Professional Audio System Components Date printed: 11.12.2006 Distribution Amplifier 1.915.307/308 The distribution amplifier cards offer splitting of one input to four or six individually adjustable outputs (versions 1.915.308 or 1.915.307, respec- tively). The input and all outputs are transformer-balanced and floating. These cards satisfy any complex requirement of signal routing and distribu- tion.
