JBL Portable Powered Loudspeakers

EON700 SeriesJBL changed the live sound market when they introduced the original EON powered loudspeaker in 1995. The EON was a radical concept – a compact, portable loudspeaker with a built-in amplifier and simplified mixer that allowed musicians, DJs, and public speakers to roll up to a gig and be ready to play or present within a matter of minutes without the need for any outboard mixers or amplifiers.

Since its introduction, the compact, portable powered loudspeaker market has continued to grow and be a first choice for performers and rental houses thanks to its convenience and ease of use. While the JBL EON is still alive and well (currently sold as the EON 700 series), JBL Professional has continued to innovate and evolve their offerings in this category. Whether you are a street busker or a house DJ, a motivational speaker or a fitness instructor, JBL has a portable powered loudspeaker to fit your needs. Let’s take a deeper dive!

“Traditional” Powered Loudspeakers

As mentioned above, the original JBL EON set the standard for portable powered loudspeaker systems. These products are typically deployed in a stereo or dual-mono arrangement of two speaker cabinets on stands flanking the performer, but can also be deployed in a single, mono configuration, on top of powered subwoofer cabinets, or even used as stage monitors. They can be used “out of the box” by connecting one or two microphones directly to one of the speakers, or by connecting a mixer to one of the inputs if more channels are needed.

IRX SeriesThe JBL IRX108BT and IRX112BT are affordable options for small engagements and solo performers. They offer big-system sound in a compact footprint and are lightweight and durable. Both models have two mic/line-level inputs, EQ presets, Bluetooth streaming, and automatic feedback suppression (AFS).

The EON700 series is a big step up in terms of capability, sound quality, and power. Packed with on-board features like Bluetooth (for audio streaming and control), DSP, and a backlit LCD, JBL offers the EON700 in a 10”, 12”, 15”, and 18” subwoofer option.

The JBL PRX900 series offers professional sound quality at an affordable price in a wide range of sizes, from 8” to 15”, plus an 18” subwoofer option. They are loaded with a comprehensive DSP suite and have massive amounts of power on tap – 2000W peak! They shine as main PA cabinets and as stage monitors thanks to their wide frequency response and built-in tuning presets.

Finally, the newest line from JBL Professional – the SRX900 series – offers best-in-class power, performance, and quality from a portable powered loudspeaker. JBL’s patented Progressive Transition waveguide makes sure sound goes where you need it (and not where you don’t). The entire SRX900 series is voiced to match each other in both frequency and phase response, so the new SRX912M, SRX915M, and SRX922 can be used seamlessly side-by-side with an SRX900 line array system.

The Newcomers: All-in-One Column Systems

All-in-One column PA systems have become extremely popular in the last decade, and it is no surprise why. They offer full-range sound in a compact, portable package which doesn’t require any mounting hardware. Portable column systems typically consist of a powered subwoofer at the base (with a built-in mixer system), and a thin column speaker above which provides an extremely wide coverage pattern, typically capable of covering a room with just one main loudspeaker. Performers can wheel in one piece of equipment and be up and running in a matter of minutes.

If you’re in the market for an All-in-One Column PA, JBL has you covered, no matter the size and input needs you might require!

EON OneThe JBL IRX One was created to be so simple to operate that anyone, regardless of background, can feel comfortable operating the system. It has plenty of power on tap (1300W!), and features a three-input mixer with XLR and ¼” inputs, audio ducking, and Bluetooth audio streaming. It is easy to set up and tear down, and a perfect fit for public speaking, outdoor performances, and fitness instructors.

The EON One MK2 improves on the IRX One by adding more power, more inputs, fully-featured DSP processing, and Bluetooth streaming and control. Not only that, the EON One MK2 can be powered by AC or a built-in battery, providing up to 6 hours of performance time. Just like the IRX One, the EON One can be packed up easily and carried with one hand, making it perfect for solo performers.

The top of the line column PA system from JBL is the PRX One, featuring up to 2000W of power, a 7-channel digital mixer, a fully-featured onboard DSP, and Bluetooth functionality, all in a compact, portable footprint. Thanks to its XLR through output, coverage can be expanded with satellite speakers, allowing the PRX One to be the main component of a PA system for large rooms. The powerful subwoofer extends frequency response to 35 Hz, and the array of 12 2.5” drivers deliver even coverage throughout the room.

Conclusion

Whether you decide to go with a more traditional solution or prefer the convenience of an all-in-one column, JBL has you covered for on-the-go PA systems. If you need help specifying the right system for your needs, reach out to the Almo Audio Team at [email protected].

AKG Wireless Microphones – An Overview

AKG Wireless Microphones

Selecting a wireless microphone system can be an intimidating experience. The amount of choices, configurations, and specifications available can be dizzying, even for those of us with experience in the industry.

Thankfully, AKG makes a wide range of high-quality wireless microphone systems to fit any application and budget, and once you know the major differences between them, you’ll be able to select the right product for your project in no time.

AKG wireless microphone systemWhat’s the Use (Case)?

Perhaps the most important consideration in selecting a wireless microphone system is where and how it will be used. Is it for a professional stage or broadcast environment where sound quality and reliability are paramount? Or is it for the lead singer for a local cover band where the highest quality for a limited budget is the key factor? Is it for a corporate or government environment where the signals may need to be encrypted to remain confidential? Identifying the needs of your end-user is the first step to determining which system is right for you.

Changing Channels

Another primary consideration is the number of simultaneous channels you will need at a particular location, as well as the amount of other wireless signals in the area. Professional touring environments may require as many as 40-50 open wireless channels (think stadiums, Broadway shows, large houses of worship), whereas a simple fitness studio may only require one or two. The ability to have a large number of simultaneous wireless channels running at the same time is a key differentiator in cost when it comes to wireless systems.

If you are installing the system in an area where there might be a considerable amount of wireless interference, such as a campus or dense urban environment, having a wide frequency range and the ability to easily identify clear frequency bands should be a prime consideration.

Digital vs. Analog

Newer digital wireless systems offer better audio quality and the ability to encrypt the signal for better security, but operate in the 2.4 GHz band, which is also where omnipresent WiFi and Bluetooth signals reside, so in dense commercial environments they may not be the best choice. Although analog RF-based systems operate on older technology, they are still the preferred choice for professional broadcast and live event systems.

So which AKG wireless system is right for you? Let’s take a look at their entire range and their pros and cons:

AKG WMS 40 MINI

AKG’s WMS 40 MINI series offers incredible value for the money. These are simple-to-operate, single-channel fixed-frequency systems which offer plug-and-play setup and a small form factor.

AKG PERCEPTION WIRELESS

The Perception Wireless series is an excellent choice for simple small-scale systems with a tight budget. It is an analog UHF-based system with basic frequency selection ability.

AKG WMS420

The most cost-effective professional system in the AKG range, the WMS420 offers a wide frequency selection band, detachable antennas to allow remote mounting, and rechargeable transmitters.

AKG WMS470

The WMS470 series is the best choice for a cost-efficient, high-performance, multi-channel system. Rechargeable batteries can be used and charged while remaining in the transmitter using the optional CU400 stand charger. The rear-mounted antennas can be detached for remote mounting.

AKG DMS100 & DMS300

The DMS100 and DMS300 systems are professional digital wireless systems from AKG, which offer pristine 24-bit/48 kHz audio and AES 256-bit encryption operating on the digital 2.4 GHz platform and are an excellent entry point to the world of digital wireless. The primary difference between the DMS100 and DMS300 is the simultaneous channel count – DMS100 allows up to (4), and the DMS300 allows up to (8).

 

AKG DMS800

The DMS800 is a reference professional-level digital wireless system designed for theaters, live productions, and tour sound applications. It offers the most accurate and reliable signal transmission in their digital line, and can be remotely monitored by Harman software.

AKG WMS4500

AKG’s flagship analog wireless system, the WMS4500, offers the highest channel quantity – up to (70) simultaneous channels, maximum reliability, and ultimate audio quality. Designed for touring sound, live performances, and broadcast applications, it is the system by which other AKG wireless systems are measured.

Conclusion

AKG offers a fit for every price point and project need. All of the above systems are available in a number of different configurations, with different transmitter options such as handheld, instrument, lavalier, and head-worn versions.

And don’t worry, if you still need assistance in selecting the appropriate AKG wireless system for your project, the Audio Team at Almo ProAV is here to help any time, at [email protected].

Pro Audio Trends 2025: The Good, The Smart, and The Acoustically Ugly

As we continue to barrel through 2025 (how is it the middle of August already?!?), I wanted to take a second to look at some of the trends that are shaping pro audio in our current landscape. We are seeing a steady march of technological breakthroughs – particularly in the conferencing space – which make our lives as audio professionals easier and our solutions more effective. However, as they say – physics is physics – and the spaces in which we are having to implement these solutions are making our success harder and harder to come by.

Let’s take a look at the pro audio landscape in 2025 – the good and the not-so-good.

All 1s and 0s – Networked Audio

In my opinion, we can declare the networked audio wars over, and Dante has emerged the victor (for better or for worse). Although many networked audio protocols still exist and see limited, niche use (AVB, I’m looking in your direction…), Dante now sees the most widespread use and adoption across the pro audio industry. Dante has become so popular and inexpensive that we are now seeing it at almost every price point – from budget mixers to entry-level speakers, and even some in the consumer audio world.

Networked audio is such a revolution that it deserves its own blog post, but put simply, it maximizes installation convenience and flexibility by routing all audio channels through a digital, networked backbone of Cat cables and network switches. For example, an event that used to require 32 individual input cables run from the front to the back of the room can now be handled by one Cat6 cable.

Not only is networked audio convenient, but it is also incredibly flexible. Routing one input to multiple outputs can now be done with a few mouse clicks. Changes can be made on the fly without even having to touch a physical cable.

Will Dante be the ultimate networked audio solution into the future? Due to its channel count limitations, likely not. But for now, its ease of use, flexibility, widespread adoption, and low cost, Dante is the go-to solution for 2025 and at least the next few years.

Audio-Technica beamforming ceiling micCeiling and Wall Microphone Arrays

We all work in the conferencing space extensively these days, and most of these spaces have the same needs: effective and professional-sounding audio which is as aesthetically unobtrusive as possible. Into this breech have stepped most of the major audio manufacturers – Shure, Yamaha, Sennheiser, Audio-Technica – with ceiling- or wall-mounted beamforming array microphones.

The amount of choices here is dizzying, but the technology in all of them is similar. They use sophisticated beamforming algorithms to isolate individual speakers, suppress background noise, and automatically adjust pickup patterns based on who is talking. Typically these are mounted on the ceiling, which eliminates the paper-shuffling noise of a table microphone, and the inconvenience and limited durability of gooseneck microphones.

Are beamforming microphones the correct solution for all conference rooms? Of course not. Most are limited to a maximum 25’x25’ coverage area, and audio at the edges of these coverage zones can sound thin. Locating microphones as close as possible to the speaker is always best practice, and some room configurations may not lend themselves to a ceiling mic array. Beamforming mics can also tend to be on the expensive side, so some situations may be better served by a more traditional solution.

The Challenge: Did Architects Forget About Sound?

modern conference roomFinally, for the trend that is assuredly NOT one that I hope sticks around, is the continued assault on acoustics that is modern conference room design. The aesthetics of modern conference room design seem to be engineered to be in direct opposition to what makes a room sound good.

Take a look at pretty much any conference room designed in the last 5-8 years: floor-to-ceiling glass walls and polished concrete floors that reflect every minute sound, exposed HVAC duct work that creates a continuous low-frequency rumble, open, cavernous ceiling spaces – it’s a miracle that we can hear anything intelligible in these spaces.

Although current mic and DSP technology can work miracles to overcome some of these challenges, the frustrating part of this is that with proper acoustic design choices, we wouldn’t need as many of these work-arounds. We are spending thousands of dollars on sophisticated signal processing to compensate for poor design choices.

These trends tend to come and go, so my fingers are firmly crossed that the open-ceiling, glass wall, concrete floor trends of this era go away – and quickly!

Wrapping Up

The professional audio industry has always been about solving problems and making communication clearer. We are seeing the promise of networked audio and advanced processing in action on a daily basis to make projects successful.

The future of pro audio is networked, intelligent, and unfortunately, still dealing with some questionable architectural choices.

Case Study: High School Stadium Audio Upgrade

One of the great parts about my job is that I get the chance to work on a wide range of exciting projects, each with their own unique challenges. The particulars of each project help keep me on my toes and ensure that we never apply a “one size fits all” approach. I wanted to share with you a recent high school stadium audio upgrade project that I worked on which is a great example of overcoming challenges – and bringing in external resources to help bring things home.

A customer came to us with an opportunity to upgrade a high school football stadium’s sound system, which was working but in need of a refresh. The existing sound system consisted of a series of Community outdoor loudspeakers mounted above the home side press box:

stadium press box

Although these speakers were functional, attendees were complaining that announcements and music could not be heard over the crowd noise, particularly at larger events with a full capacity crowd, and particularly on the visitors’ stands, which are over 400’ away on the other side of the stadium.

stadium aerial view

My first thought was to add speakers to the light poles on the visitors’ side to improve coverage and intelligibility. However, according to the customer, the school was unwilling to add trenching to the other side for this project, and there were no known pathways connecting the two sides.

With this disappointing piece of news in hand, I knew I needed a second opinion, so I decided to reach out to one of the most capable and helpful people in the industry – Harman’s Dave Tewksbury. Dave is an amazing and knowledgeable resource on all things JBL and BSS, and I knew he could help to find a creative solution.

AW566 loud speakersAfter explaining the limitations of the project, Dave surprised me when he stated that JBL’s AW series of speakers (the AW566 in particular) have the ability to project over that distance when paired with the proper amount of amplification.

But what is the proper amount of amplification? In order to determine that, we need to have a target sound pressure level at a given distance. Although ideally we would want something above 90 dB SPL to truly overcome all crowd noise, the amount of amplification required to hit that from 430’ away would be both impractical and would overload the speaker.

Together we settled on a target of 85 dB SPL, which according to both Crown’s amplifier power calculator and JBL engineers, would require approximately 1083 watts of power for the AW566:

amplifier requirementsFinally, something we could work with! We settled on the Crown DCi 2×1250 to power (2) JBL AW566 loudspeakers mounted above the press box to provide sound to the visitors’ side. The home side situation was much easier to solve for – it simply required selecting speakers with the appropriate coverage patterns. Those turned out to be (3) JBL AWC82 speakers, powered by a Crown DCi 4×600. We also recommended relocating the home side speakers so that they would no longer be in the acoustic shadow of the press box roof, as the previous Community speakers were.

Through all of this legwork we were able to provide the customer with a reasonably-priced solution to drastically improve the acoustics and intelligibility of their sound system. We were able to navigate challenges which prevented implementing the “ideal” solution, and were able to provide them with an easy-to-implement significant upgrade to their current system.

My thanks as always to the invaluable Dave Tewksbury, as well as all of the great folks at Harman, for their continued support, knowledge, and help!

Digital Signal Processors – a Beginner’s Guide

I was recently asked to advise on a project where the customer was installing new AV equipment in a public meeting space. The audio system was to include ceiling array microphones, gooseneck podium microphones, as well as a number of wireless lavalier and handheld microphones. The question I was being asked was “can you recommend an appropriate mixer for this application?”.

At first glance, an audio mixer seems to be the appropriate tool for the job – after all, a mixer takes a number of audio input sources, allows you to control the volume and equalization of each source, and mixes them into a combined output signal to be sent to an amplifier and eventually loudspeakers.

But what if you need to send multiple output signals to multiple destinations? What if some signals need to be sent to some outputs but not others? What if you need to instantly change the signal routing based on the room configuration? What if you need to apply auto echo cancellation (AEC) to any of the signals to prevent echo and feedback? And most importantly – what if you do not have a dedicated technician willing and able to sit behind the mixer to configure it and make adjustments?

For all of these reasons (and plenty more), the appropriate tool for this application is a digital signal processor (DSP), not a mixer. So, let us take a look at DSPs, their features and benefits, and where they are appropriate (and not) to use!

Anatomy of a DSP

One way of looking at a DSP is as a “mixer in a box” which can be remotely controlled. Similar to a mixer, a DSP will have a number of input channels and output channels – typically 12 (in) x 8 (out) – but many other configurations exist. Unlike a mixer, which is made to lay on a table or desk and features lots of volume sliders and knobs, a DSP is a small box which is made to be installed in an equipment rack and typically features no knobs or obvious controls.

blu101Below is the front and rear of a BSS BLU-101, one of the most popular and powerful DSPs that we sell:

As you can see, it does not look much like a mixer at all, but the functionality is similar. It has twelve inputs (the green ports on the right side), eight outputs (the orange ports in the middle), an ethernet port for connecting it to a network, an RS232 port for allowing the unit to be controlled remotely, BluLink for connecting to other Harman devices, and a set of GPIO control ports which can be used for monitoring other devices or accepting signals from external devices.

ac5swhtusAs mentioned above, there are not any controls or buttons on the front panel. Instead, DSPs are generally controlled by external control systems, such as AMX, Kramer, or Atlona. Users interact with a custom touch panel to send control signals such as channel mute, volume control, input/output routing and mixing, gating, and more! In simpler systems, BSS DSPs can also be controlled by a simple button/volume knob control panel, such as the BSS Contrio series.

Due to the versatility and abilities of DSPs, they do require configuration and setup before being deployed. When selling a DSP, always check to make sure that your customer has someone on their team who is familiar with configuring and setting up DSPs. In most cases, the manufacturer will have online training programs which can help them get up to speed. For example, Harman’s Professional Training Portal offers full courses on BSS programming for free! If the customer needs additional help or is simply pressed for time, Almo’s own LinkLab Professional Services team has certified DSP programmers ready to help!

When to Recommend a DSP

Now that you know a bit about what makes a DSP tick, when should you be recommending a DSP solution over a regular mixer?

  • Medium to Large Conference Rooms: any time a customer mentions conferencing, particularly for larger rooms with multiple microphones, a DSP should be recommended. DSPs have the flexibility and power to manage the complex routing needed to interface with conferencing devices. Make sure that your DSP has a USB port for conferencing, as well as auto echo cancellation (AEC)!
  • Training Rooms/Lecture Halls: for applications where there will not be a dedicated AV Tech available to manage the system, a DSP with preset scene recall and automatic level control is essential.
  • Building-wide Systems: any complex system where multiple rooms are being controlled from a central head-end system requires a DSP (and usually a large one) to manage the routing of audio from room to room.

cms14Of course, a DSP is not a fit for every situation. For example, most live performances (musical or otherwise) are better suited to being controlled by a real live person in front of a mixer who can respond in real time to the action on stage. Additionally, smaller, less complex systems (such as in a bar, restaurant, or retail store) which do not require advanced routing or signal control might be better suited to use a rack-mounted mixer (such as the JBL CSM series) or a zone controller (such as the dbx ZonePro).

Conclusion

Hopefully, this serves as a good introduction into the capabilities and use cases for audio digital signal processors. Do not be intimidated by the complexities of DSPs – at their heart they are simply tools for making audio sound great and getting it where it needs to go.

The good news is that you do not have to be an expert to sell DSPs. The audio team at Almo is here to help you navigate the details. Simply be on the lookout for the opportunity, ask some questions, and email [email protected] to help figure out the details. We are here to help!
