The DAV Electronics BG9 is a single channel Decca Heritage Mic-Pre (from the BG1) with a dedicated DI channel.

The features of this channel microphone amplifier consist of low noise and low distortion. It offers switched gain controls for high accuracy level setting in 4 dB steps.

One mic channel (channel 1) and one dedicated D.I instrument input (channel 2) with balanced line level output and buffered output to amp (ideal for mixing live and D.I. guitar for fuller sound), level indication, high pass filter (switchable on channel 1 onyl), 26dB pads (switchable on channel 1 only) and 48v phantom supply (switchable on channel 1 only).
