8.2. Optional Modules

8.2.1. D-001T (2-channel input module)

The D-001T module is designed for use with the 9000 Series amplifiers.
Up to 4 modules (8 channels in total) can be inserted into the amplifier.
The module can handle signals ranging from microphone level (–60 dB) to line level (–10 dB) in 9 input
sensitivity levels.
Phantom power (24 V) can be supplied for microphone level (–60 dB to –30 dB) signals.
The D-001T module has an internal digital signal processor that can process input signals.
The D-001T module is required to use a VOX (Voice Operated Exchange) function and input channel level

8.2.2. T-001T (Audio output expansion module)

The T-001T module is designed for use with the 9000 Series amplifiers and can expand 2 output channels per
module.
Since the main unit has 2 fixed outputs, the audio output can be expanded to 8 channels by using a maximum
of 3 modules (6 channels).
