The DA103 is a high quality Line level 1X3 Distribution Amplifier which accepts a single analog audio input and provides three independent +22dBm servo-balanced outputs in a compact 1/3 RU enclosure. A master gain control provides overall level setting, and three output trim pots let you adjust each output line individually. The DA103 accepts a line level audio input, balanced or unbalanced, at -20, -10 or +4dBu nominal level 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.
