The C-001T is Control I/O expansion module designed for use with the M-9000 and can provide up to 8 channels each of input and output expansion. Since the main unit has 4 preinstalled inputs and outputs each, the control input and output can be expanded to up to 12 channels each when the C-001T is used.
The ZP-001T is a zone paging module designed for use with the M-9000
and functions as interface to connect the M-9000 to an analog PABX,
allowing zone paging to be initiated from the PABX. There are two operation modes: ring signal and paging port modes. Broadcast can be initiated regardless of operation mode.
The AN-9001 is an electret condenser microphone designed for ambient
noise sensing. It is used in conjunction with the AN-001T Ambient Noise control module in the M-9000. It can be mounted in an American Standard 1-gang electrical box in the ceiling or wall.
The T-001T is a plug-in module designed for use with the M-9000 and provide two independent balanced outputs. It can drive load of 600Ω up to +16dB. It can process effect for TONE/EQ/ COMPRESSOR to two inputs independently.
The D-001T is a plug-in module designed for use with the M-9000 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 -60dB to -10dB. Phantom power (+24V) can be supplied for condenser microphone use. The D-001T can process effect for TONE/EQ/COMPRESSOR to two inputs independently.
