ADA-881 Audio Distribution Amplifier

Module

Overview

The ADA-881 is a high quality audio distribution amplifier with 8
low-impedance outputs. Excellent output isolation is assured by individual
drivers for each output. The amplifier is designed to meet the most demanding
requirements for AM/FM/TV broadcast and program production systems.
Heading the list of the amplifier’s exceptional performance characteristics is the
100 dB S/N ratio. Flat frequency response, carefully controlled roll-off and very
low distortion ensure a virtually transparent transmission path.
The input is overvoltage protected up to 120 volts AC or DC. The
transformerless, balanced input is normally bridging, but can be terminated by
installing a suitable resistor. Unbalanced input is converted to balanced output.
Isolation between modules in the mounting frame is better than 100 dB over the
entire audio frequency band.
