Persistent Systems Unveils New Dual Channel PTT Device for the MPU5

Tuesday, October 10th, 2017

Dual PTT will improve networked communications and eliminate extra legacy radios

New York, NY  – Persistent Systems, LLC (“Persistent”) announced today that it is unveiling its new Dual Channel Push-to-Talk (“Dual PTT”) accessory for the MPU5. The Dual PTT, said company officials, will allow the MPU5’s audio capabilities to reach their full potential.

The Dual PTT allows the user to quickly and easily select between 16 talk groups as well as control volume levels for each talk group independently. When paired with a stereo headset, the two selected talk groups are heard in the left and right ears, and the volume level in each ear can be controlled independently.

With the MPU5 and Dual PTT, a single MPU5 can communicate on two talk groups either independently (by pressing a single PTT button) or simultaneously (by pressing both PTT buttons). In the past, when a user needed to communicate with two different groups (channels) of users, that user needed to carry two separate Land Mobile Radios (LMRs). Therefore, the MPU5 and Dual PTT significantly reduces size, weight, power, and cost (SWaP-C) burdens on users.

This is possible because the MPU5 is an IP radio, where talk groups are multicast addresses, instead of an LMR radio, where channels are different RF frequencies.

“It used to be that a commander would have to carry a PRC-148 and a PRC-152,” said Brian Mcdonald, Field Operations Manager at Persistent. “Now the commander just carries the MPU5 and can use the Dual PTT to talk to both groups. Carrying one radio instead of two will both save money as well as reduce the load on the soldier, which is a major selling point with customers,” Mcdonald explained.
The Dual PTT also serves as the interface into the MPU5’s Radio over IP (RoIP) subsystem. Users can tether legacy LMR radio systems to the MPU5, and associate each of those radios with one of the 16 talk groups as a multicast address on the network. When an MPU5 user communicates on that talk group, the MPU5 “keys up” the LMR radio and transmits audio through it.

“For the warfighter, this means one can tether a TACSAT channel on a vehicle to the RoIP port on the MPU5 and talk on TACSAT from within a building or tunnel while carrying only an MPU5 and Dual PTT,” said Dr. Herbert Rubens, Founder and CEO of Persistent. “The MPU5’s RoIP capability is compatible with PRC-148s, PRC-152s, Tactical Satellite (TACSAT), Fires Net, Public Safety LMRs, or standard walkie-talkies, which means, for example, being able to talk to Command Net, Assault Net, Fires Net, etc. whenever it’s suddenly required by the mission.”

Persistent has begun accepting orders for the Dual PTT.


AUSA 17 – NoizeBarrier by OTTO Engineering

Tuesday, October 10th, 2017

OTTO’s NoizeBarrier consists of in ear plugs and a case which doubles duty as a charger. The plugs offer increased situational awareness by digitally lowering ambient noise up to 15 dB in high noise environments, with up to 40 dB protection from high impulse noise. Additionally, in enhanced hearing mode, they amplify low noise up to 5 x.

While it may take 12 hours to charge the waterproof case from shore power, it offers 15-30 recharges of the ear pieces. Each of those charges will last up to 16 hours.

Revision Introduces New ComCentr2 Tactical Communications Headset System at AUSA 

Monday, October 9th, 2017


Essex Junction, Vermont (October 9, 2017) – Revision Military, a world leader in integrated soldier solutions, is proud to unveil the SenSys ComCentr2TM Tactical Headset System at the Association of the U.S. Army (AUSA) Annual Meeting & Exposition in Washington, D.C., October 9 – 11. Drawing from Revision’s background in operational focused integrated head protection systems and power management solutions, this next-generation communications and hearing protection device represents the newest addition to the Company’s line of integrated soldier system products. The ComCentr2 Tactical Headset System will be commercially available in the first Quarter of 2018.


“This is not a one-off product; this R&D direction represents Revision’s tenacity and long-standing dedication to integrated soldier systems,” said Jonathan Blanshay, CEO, Revision Military. “Revision has worked in parallel with companies in this field, collaborating to seamlessly integrate helmet systems with tactical headsets. Leveraging past successes, our extensive knowledge of this technology, and our considerable capabilities, we are now taking the bold step to set the bar higher in the tactical communications and hearing protection industry, and to take our head systems solutions to the next level of integration. The ComCentr2 Tactical Headset System will integrate with a variety of helmets, hubs and devices, will improve team communication, will keep pace with future technology, and, crucially, will provide unfettered situational awareness for warfighters in hostile, noise-cluttered settings.”


Integrating advanced electronics and software into a sleek, comfortable and user- focused design, Revision’s ComCentr2 Tactical Headset System offers high quality, natural sounding audio and enhanced sensory performance. The fully digital system enables mission critical communication; improving command, control and communication on the battlefield while enabling dismounted close-combat users to detect vital sounds in a noise polluted environment.


The SenSys ComCentr2 Tactical Headset System is designed to integrate seamlessly with modern helmet systems, including Revision’s Special Operations Forces helmet, the Batlskin Caiman Head Systems suite. The headset’s fully digital design allows for advanced electronic features and provides an upgrade path for technological improvements. User customizable, the ComCentr2 is an ideal communications solution for the modern dismounted close-combat warfighter and plug and play with the wider soldier system.


Digital Active Noise Reduction (ANR) technology mitigates low frequency noise generated by military vehicle platforms, protecting hearing, preventing fatigue and improving speech intelligibility. Full 360° situational awareness provided by an array of two forward and two rear facing microphones provides front and back audio detection, enhancing user awareness and closing the gaps left by existing systems. 3D spatial communication enables users to hear radio communications in a three- dimensional listening environment, further decreasing the cognitive burden caused by monitoring multiple nets.


The ComCentr2 System includes the Human Interface Device (HID), an intuitive, hand held control unit designed to fit comfortably in the user’s hand. Buttons on the device enable radio transmission, volume adjustment and switching between radios. Unlike systems containing a fixed number of ports, the HID includes a lower section outfitted with a custom dongle. Supporting a wide variety of system configurations and communication devices, dongle attachments enable mission specific configurations in multi-role and multi-channel environments, while ensuring compatibility with legacy and future systems.

Inside Safariland’s Acoustic Lab

Monday, October 2nd, 2017

Safariland’s TCI boasts an acoustic lab where they can replicate and work to mitiagte those sounds which threaten the hearing of military, law enforcement, other ar ed professionals and recreational shooters alike.

“There’s a few different ways we can use our equipment to confirm a reading, and we use it for both R&D and production, and getting certifications,” says Brad Medine, Category Director for TCI.

Additionally, they can record sounds created dueing ballistic testing and use those as samples for their work. This video gave you a quick overview of their efforts.
