17. AC power cable
Connects to power source.
18. Speaker output terminals
Connect to speakers.
19. Output terminals
Select output impedance with this terminal.
20. Low-cut switch
Cuts off unnecessary low frequency.
21. Module input ports
Accept 900 series plug-in modules. For the
selection of the most appropriate modules, refer
to Plug-in Module Instruction manual.
22. Bridging input/output terminals
–20 dB (100 mV), 3.3 kΩ
This terminal is used as a mixing bus.
Connecting this terminal to the similar terminal of
another amplifier achieves mixing. The signals
appearing at the terminal are independent of all
controls except input volume controls so that this
terminal can also be used as recording output.
The input impedances of the equipment to be
connected here should be more than 10 kΩ.
23. Mute terminals
Activate mute control only to the modules having
mute function.
Short-circuiting the Mute terminals mutes the
modules set for “mute receive” function.
24. Cord clamp
Clamps off lead wires from module inputs, mute
terminals and bridging input/output terminals.
