In the Spring of 2010 while working to set up sound for a ballroom for a big wedding DJ Rick (now retired we’ll just call him Rick) and DJ Ty.. yep that DJ Ty from all those videos on YouTube came up with a solution. A repurposing if you will of a wireless microphone system to send audio to a powered speaker. Although they were not likely the pioneers in doing this, after some refining and tons of research and education the AGIPRODJ Wireless Speaker Solution was born. At the time using the Sennheiser EW G2 ENG kits to create an extremely portable and reliable way to link from a powered speaker to a remote powered speaker as much as 100 ft away.

Since that time, Sennheiser has released updated versions of the ENG kits: first the G3, then the G4. Both continued to anchor our portable wireless speaker systems. Over the years, plenty of other wireless audio products have come onto the scene, but in our experience—and backed by hundreds of five-star reviews from working DJs—the Sennheiser-based kits are still the most trusted, road-proven, and flexible solution out there.
With more than 2,500 kits sold, each one built specifically to deliver clean, reliable wireless audio to powered speakers, the feedback has been consistently strong. When Sennheiser announced the phase-out of the EW 100 G4 lineup in 2024, we knew it was time to evaluate next-gen options without giving up the performance that made this system a go-to for so many DJs.
In April of 2023 the first kits in the EW-DP lineup were introduced as the 5th generation of transmitters and receivers for use with video camera and recording applications in mind. This of course is what the ENG kits had been designed for; Use with video camera rigs’ but as we found out early on, they can send high quality audio from mixer to speaker, controller to speaker, and as a relay sending audio from one speaker to another.
It’s time to dig in and see how these kits work and what make EW-DP a better solution than the previous versions. With traditional UHF system they rely on companding which means it must compress analog audio at the transmitter and then decompress once it arrives to the receiver and although in most cases you never notice, but when compared to a digital wireless UHF removing the commanding process creates a noticeable improvement in sound quality. With EW-DP, the transmitter can now support up to 134 dB of dynamic range which is roughly 5X what EWG4 systems could support. Because of this dynamic range there is no longer a need to adjust the sensitivity of the system. All the settings can be controlled on the receiving unit, or with the use of the Sennheiser Smart assist app on your phone or tablet. Another spec that sets this EW-DP far and away ahead of any competition we looked at is it provides the lowest latency for sending audio at 1.9 milliseconds.
There has been talk in recent years of several solutions that are digital but operate in the sometimes crowded 2.4 GHz range to offer wireless speaker systems. Picture this you are using a 2.4 wireless system to send audio from a mixer in a ballroom for a big wedding. You could be competing with wireless routers and modems, along with wireless DMX which can interfere with your audio. With the EW-DP digital over UHF you have thousands of channels to choose from and the ability to do a scan of best frequencies can aid in reducing and even eliminating signal interference.
We are excited to introduce our updated version of the AGIPRODJ Wireless Speaker Systems all built around the EW-DP Portable digital UHF wireless systems for filmmakers, content creators, and broadcasters. With the addition of a single cable connected to the transmitter you will be able to send near latency free wireless audio from any mixer, DJ controller or powered speaker output to relay sound to a remote speaker. We have curated three solutions that we feel cover most applications. You can even add additional receivers as you need. Keeping in mind that you can tune an infinite number of receivers to one transmitter and if they are within range. This will give you the flexibility to place speakers around an event space or in outdoor settings without the pain of long cable runs.

AGIPRODJ / SENNHEISER Wireless Speaker Solution FAQ:
Q: What’s the max range of the EW-DP wireless audio system?
A: You can expect up to 100 feet line-of-sight range in typical event spaces. Keep transmitters elevated and clear of obstructions for best results.
Q: Is there any audio delay or latency?
A: Latency is just 1.9 milliseconds — completely unnoticeable and far better than most 2.4GHz systems.
Q: Can I use more than one receiver with a single transmitter?
A: Yes! You can pair multiple receivers to a single transmitter as long as they’re within range and tuned to the same frequency.
Q: Do I need to set gain levels on the transmitter?
A: Nope. The EW-DP system has 134dB of dynamic range and handles level control on the receiver side. Just plug in and go.
Q: Can I use this with my DJ controller or mixer?
A: Absolutely. Each kit includes locking XLR cables to connect straight from your balanced output to the transmitter and from receiver to speaker.
Q: How is this different from using 2.4GHz wireless audio systems?
A: EW-DP uses UHF, not 2.4GHz — so you’re not fighting Wi-Fi, Bluetooth, or wireless DMX signals. Better reliability, more channels, less interference.
