Pro Acoustics Designs Custom PA System For State Corrections Facility In Oklahoma

When the Oklahoma Department of Corrections state facility where Tod Dillard works needed new audio systems, Todd reached out to Pro Acoustics for help. The facility opened in 1962 and was in need of an updated public address system for its three housing units.

Two of the housing units are open bay type living areas with approximately 215 inmates in each. Due to large fans running constantly, these units are very noisy so inmates couldn’t hear when they were being paged or when announcements were being made.

Tod explained the trouble they were having with their old units to Merry Grant, a sales engineer with Pro Acoustics. After receiving the floor plans for the units, Merry designed two systems to meet their audio needs.

The custom PA systems that Merry designed featured Atlas Sound GA-15T Horn Loudspeakers, Pure Resonance Audio RZMA120BT 4 Zone Mixer Amplifiers, and Desktop Microphone Packages with Pure Resonance Audio UC1S vocal mics and adjustable stands.

Merry chose to use the Atlas Sound GA-15T horn loudspeakers in the systems because they are perfectly suited for voice paging and music transmission. The double re-entrant construction of these horns optimizes loudspeaker output to penetrate ambient sound levels. They are also made from high-impact plastic and will withstand outdoor installation in high-humidity environments.

The Pure Resonance Audio RZMA120BT is a multi-zone mixer amplifier with 4 x 120-watt output capability at 4 Ohm, 70, and 100 Volts. Its advanced matrix technology allows four-zone selectable inputs to be assigned to a zone, or across multiple zones with the push of a button, making this mixer amp a perfect choice for paging and announcements in the different housing units. The RZMA120BT is also equipped with built-in MP3, FM tuner, Bluetooth, and recording capability.

Completing the systems are two desktop microphone packages that include Pure Resonance Audio UC1S vocal mics, Atlas Sound DS7E adjustable desktop stands, and 20ft cable. The Pure Resonance Audio UC1S Ultra-Clear™ dynamic vocal microphone delivers ultra-clear audio with a super heavy-duty housing and ultra-quiet On/Off switch. The Atlas Sound DS7 adjustable height desktop mic stand is a versatile stand that may be adjusted from 8" to 13". This package is an excellent value perfect for public address and announcements, the two audio solutions that Tod was looking for.

Tod says that he had no reservations about the systems or any of the products, and he has seen the audio “greatly improve” in his facility thanks to the quality of the system that Merry designed. He gives the equipment a strong “10/10” after experiencing the improvement in his audio.

Merry successfully customized a system to meet the needs of Tod’s facility, and Tod says, “I really enjoyed working with Merry. I wish all the vendors I deal with could be just like her. She was definitely a pleasure to deal with. Don’t let that girl getaway.”

It was a pleasure working with Tod, and we were pleased to help provide a solution to the audio issues that his facility was facing.
