 AMP1A Series User Guide
Description
Power
Each unit comes with a standard 24VDC/3.0A internal power supply 
and connects an A/C mains power source (65W, 100 to 240 VAC, 50/
60Hz) to the IEC connector provided on the rear panel of the unit.
Electrostatic Discharge (ESD)
As with most electronic equipment, static discharges can damage 
components within the unit. Take precautions to ensure your 
installation environment is not subject to ESD.
Description
All models in the AMP1A series contain four high performance 
transducers driven by three power amplifiers: two amplifier/driver 
combinations handle midrange and high frequency information in 
stereo, while the third center channel reproduces information below the 
500 Hz crossover point through dual woofers.
All AMP-1A analog audio models come equipped with stereo volume 
and balance potentiometers, a power indication LED, and a headphone 
output. Output limiter circuits are incorporated to protect the speakers, 
and extensive magnetic shielding allows placement immediately 
adjacent to video monitors with no color impurities.
Application
The AMP1A Series is ideally suited for use in VTR bays, mobile 
production vehicles, teleconferencing installations, multimedia 
systems, satellite links and cable TV facilities, and on-air radio studios. 
Designed and manufactured in the U.S., the AMP1A is backed by a 
strong warranty and a satisfaction guaranteed return policy.
