SD8 is a 2U 19” rack eight channel stage preamp with line drivers and designed with individual line drivers that maintain audio signal integrity over long cable lengths (As cable lengths increase, the length of the cable creates a high capacitance load that most microphones have difficulty in driving). Eight independent mic inputs, gain control adjustment, -20 dB pad and 48V phantom power, signal level bar LED display.Each input has two outputs allowing signal routing to two separate locations such as front of house and monitoring consoles.
