The D-001T is a plug-in module designed for use with the 9000 Series amplifiers and can provide two independent balanced inputs. The D-001T can handle signals ranging from microphone level to line level by controlling their input sensitivity in 9 increments from -60 dB to -10 dB. Phantom power (+24 V) can be supplied for condenser microphone use. The D-001T can process effect for TONE/EQ/COMPRESSOR to two inputs independently.
