BASIC DESCRIPTION
The SD8 is an 8-channel microphone preamplifier combined with a line amplifier. It is designed for
primary processing of microphone signals. Impedances of the SD8 inputs are properly adapted to
most of the microphones used, the signals are amplified and the inputs, thanks to their low imped-
ance - (50 ohms) can drive, without any loss, long symmetrical lines to the mixers - (up to 500m).
It is suitable to place the SD8 directly on the stage, close to the active microphones as practical, as
most microphones cannot provide loss-free excitation of long cables. 48V phantom supply is available
to supply condenser microphones. Each channel is equipped with two identical outputs that can be
used for connection of a main mixer and monitoring desk, recording device, etc.
