Audio Technologies DA103 Distribution Amp, 1x3

The NANOAMP MIC and Line level 1X3 Distribution Amplifiers consist of independent +22dBm servo balanced outputs in 1/3 RU enclosure. The master gain controls have three output trim pots. The DA103 accepts a line level input, balanced or unbalanced audio at –20, -10 or +4dBu nominal and provides a line level output at +4dBm nominal level to balanced or unbalanced output lines. The DA103 input/output connectors are two piece solderless “Phoenix” types, individual for each input and output line.

The DA103 accepts a maximum line input level of +22dBu to high impedance (20Kohms) balanced instrumentation amplifier input (A1) and drives three servo balanced 600-ohm (minimum load) outputs (A3, A4, A5) up to +22dBm maximum. An internal input gain setting jumper plug optimizes the input stage gain, noise and headroom for nominal inputs at -20, -10 or +4dBu. The servo-balanced outputs automatically detect single-ended (one side grounded) loads; remove the drive signal from the grounded output and double the signal applied to the ungrounded output thus maintaining equal gain for both types of loading.
