1. General
The flashlink ® DA-AA is a dual 4 output analogue Audio Distributor. The DA-AA can be configured as
either a dual 1x4 or a single 1x8 amplifier. The latter configuration is made by connecting the inputs in
parallel or using DIP switch on PCB. The Distribution amplifier has differential inputs and differential
outputs. Overall gain can be set by DIP switches or by potentiometer for high precision gain setting. The
gain range setting is from -12 to +12 dB. The input signal can be mixed to the other channel using a DIP
switch. The Distribution Amplifier handles analogue audio signals from 20Hz to 80 kHz. The DA-AA is
designed for all audio distribution purposes in studio, duplication and Broadcast applications.

OUTPUT CONFIGURATION
There are two groups of four outputs, ANA1 and ANA2 output. The two groups are individually
configured using DIP switch 3 and DIP switch 4. The switch sets which of the input that is connected to
the output.
