1. Monaural input terminals [1, 2]

Electronically-balanced 3P removable terminal blocks.

Input level: –60 dB to –10 dB selectable.

Input impedance is 10 kΩ when the phantom power is OFF, and

3 kΩ when ON.

2. Monaural output terminals [1, 2]

Electronically-balanced 3P removable terminal blocks.

Output level: 0 dB

Output impedance: 600 Ω

For unbalanced connection, connect the unit's Hot and Earth

terminals to the connected equipment's Signal and GND

terminals, respectively. (Keep the unit's Cold terminal free.)

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

meter.

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).
