ADA-210/ADA-210A Audio Distribution Amplifier
The ADA-210 and ADA-210A are two channel, 1 input by 10 output audio distribution amplifiers for analog audio signals.
On the ADA-210, a gain control is provided for each of the two channels. All ten outputs for each
channel are adjusted simultaneously. On the ADA-210A, a gain control is provided for each
individual output. Gain controls for both models are easily accessible from the front panel.
Each unit occupies a single EIA rack unit of space, and can function as two independent 1x10
distribution amplifiers, a 1x20 mono distribution amplifier, or as a stereo 1x10 audio distribution
system.
All inputs and outputs are balanced, and the outputs feature short circuit protection.
All connections to the ADA-210 and ADA-210A are made on the rear panel of the unit. The rear
panel configuration is shown below.
