9-pin removable terminal block, 8-circuit control input terminal.
Individual input functions are assigned on the front panel setting screen
of the main unit.
8. Control output terminal [OUT 1, 2, 3, 4, 5, 6, 7, 8, E]
9-pin removable terminal block, 8-circuit control output terminal.
Individual output functions are assigned on the front panel setting screen
of the main unit.
The C-001T module is designed for use with the 9000 Series amplifiers and can provide up to 8 channels
each of input and output expansion.
Since the main unit has 4 fixed inputs and outputs each, the control input and output can be expanded to up to
12 channels each when the C-001T module is used.

9. Monaural input terminals [1, 2]
Electronically-balanced 3P removable terminal blocks.
Input level: –60 dB to –10 dB selectable.
Input impedance is 10 k
Ω when the phantom power is OFF, and 3 kΩ
when ON.
The AN-001T module is designed for use with the 9000 Series amplifiers and automatically adjusts the
amplifier's output volume in response to the change in ambient noise level.
Maximum 2 AN-001T modules (4 channels in total) can be used per 9000 Series amplifier.
It can handle signals from microphone level (–60 dB) to line level (–10 dB) by controlling the gain in 9 steps.
Phantom power (+24 V) can be supplied to a condenser microphone.
The AN-001T's inputs are for detecting ambient noise level and cannot be used as normal audio inputs.
Ambient noise fed to the inputs can be monitored when the monitor function is set to ON in the Input setting
flow.
