The VHD SD8 is an eight-channel stage preamp 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. The SD8 features eight independent mic inputs with gain control adjustment, -20 dB pad, and 48V phantom power. Each input has two outputs, allowing signal routing to two separate locations such as front of house and monitoring consoles. A five-bar LED display provides signal level information, and a rotary knob provides 0db to +30 dB of gain control.
