The DAA-104 Digital Audio Distribution Amplifier is solution for distribution of digital audio signal over long distances
(up to 200m). An hybrid 75/100 unit allowing signals to be converted from balanced to unbalanced format without
the amplitude and phase distortion associated with transformers. The modules mount into the SRU-312 frames 3RU,
12 module capacity.
