Hearing Loss: The Invisible Disability - Is your facility ADA Compliant? 
Almost anyone can easily explain the purpose of a wheelchair ramp, wheelchair signage on doors, or signs translated into Braille. Less known are the effects of the "invisible disabilty", also known as hearing loss. In 2012, legislation went into effect that requires all new construction and renovations to meet enhanced ADA standards for assistive listening sytems. Listen Technologies has published a white paper outlining these new requirements that you can DOWNLOAD NOW. 

Thinking Outside the Box with ListenIR - SIMPLY BRILLIANT

ListenIR systems use infrared light to transmit audio, much like a television remote control. An IR system is made up of a radiator, transmitter, and receiver. Unlike RF systems, an IR system incorporates line-of-sight technology, and is therefore very secure for confidential transmission fo the audio signal within a room. Listen LT-84-01The ListenIR system is great for classrooms, corporate boardrooms, courtrooms and wherever a private audio signal is needed. Because of its versatility, ListenIR can be used for a wide range of unique applications. Listen Technologies has detailed many of these ideas in this blog that you can read here...

The Installed System Amplifiers are designed to meet the needs of sound system designers and contractors. Versatile loading options and a comprehensive feature set make the ISA Series a rugged, cost-effective power solution for any permanently installed sound system.

Designed as a cost-effective solution specifically for sound contractors, the ISA Series features seven models including four low impedance models (ISA 280, ISA 450, ISA 750, ISA 1350) rated for 2-ohm operation, and three "Ti" versions with isolated 25, 70 and 100 volt outputs for distributed audio systems (ISA 300Ti, ISA 500Ti, ISA 800Ti). Versatile loading options and a comprehensive feature set make the ISA Series a rugged, cost-effective power solution for any permanently installed sound system.

Unique among distributed sound power amplifiers, the "Ti" versions will drive 8 or 4 ohm loads and a distributed system on the same channel simultaneously. This enables a contractor to reduce the number of required amplifier channels by allowing a limited number of distributed speakers to be attached to the same amp as is powering the main sound system. 

Housed in a rugged 3-U chassis, all seven models feature rear panel gain controls for tamper resistant operation with 2 dB detents for quick and repeatable settings. Inputs include both XLR and detachable Euro-style connectors. Outputs feature covered barrier strip connectors for safety agency compliance, and for added versatility, a DataPort V2 (Version 2) terminated with an HD-15 connector is provided for use with DPV2-compatible signal processing accessories such as the XC-3 Crossover, SF-3 Subwoofer Filter, LF-3 Low Frequency Filter and the DSP-3 with external power supply.

Selectable high-pass filters are included to protect speakers and prevent speaker transformer saturation with minimal effect on program material. The ISA Series provide additional protection circuitry including DC, infrasonic, thermal overload, RF and short circuit protection.

On the ISA 750 and ISA 800Ti, class H complementary bipolar output circuitry increases system efficiency by reducing AC power draw and waste heat by 40%. Cooling is accomplished via an automatic variable speed fan, which pulls air from back to front.
