Distribution Amplifier
The ATI DA416S Quad Distribution Amplifier is a four-input, sixteen-output distribution amplifier that
accepts four input signals and distributes each input to four individually adjustable, active balanced outputs.
Other features include:
• Separate LEDs for each 1x4 channel indicate input signal presence
• Phoenix connectors for easy pre-wiring and flexible output channel assignment
• Individual wide range audio taper output level controls
Feedback Reducer
The Shure
®
DFR22 is a two-input, two-output digital audio processor with feedback reduction. The 2 x 2
matrix mixer allows either or both inputs to be routed to either or both outputs, with additional controls for
levels and polarity. The unit stores sixteen presets and provides 24-bit conversion, 48kHz sampling and a
minimum dynamic range of 100 dB. Other features include:
• Digital feedback reducer, in both mono and stereo processors
• Automatic gain control
• Parametric and graphic equalizers
• Mono & stereo compressor/limiter
• Ducker
• Two-way crossover & splitter
• Subwoofer control
• Peak stop limiter
ADA Hearing Assist System
The Listen
®
LT-800 Stationary Transmitter in the audio rack allows individuals to
experience every word at an event. This system is designed to broadcast the audio
signal throughout the facility. It is capable of transmitting to multiple receiver types
and its adjustable receivers allow each user to have full volume control.
The Listen LT-4200 Portable FM Receiver ( Figure 10 ) provides users with the choice of
57 channels and accessory options ideal for a wide range of applications. The receivers
are digitally tuned so transmission will not drift, assurance that when you select a
channel it stays on the channel.
Wireless Personal Stereo Monitor System
The Shure
®
PSM
®
900 Wireless in-ear monitor system is used for on-field/on-stage talent.
The system includes a transmitter in the audio rack and a receiver ( Figure 11 ) worn by the
performer that allows for personal adjustment of mix and volume and compensates for
delay from the sound system.
Sound travels at 1120' (341 m) per second. This produces a noticeable delay as one moves
away from the speaker. Even experienced performers have trouble adjusting to this delay.
A wireless in-ear monitor system provides a real-time signal to the talent and blocks the
sound delay from their ears.
Note: If more receivers are required and the transmitter is already installed,
additional receiver packs and headphones are available to purchase.
