Rear Panel

AC Power Cord

Connects to power source.

AC Outlet (Unswitched)

Provides AC power for auxiliary equipment with

power consumption of up to 500W.

Output terminals

Connect to speakers.

Impedance Select Switch Selects the desired impedance.

Enables unbalanced output of low impedance when this switch is set to "DIRECT".

Module Input Ports

Accepts optional PLUG-IN MODULES. Module selection is determined by application. For details, refer to Plug-in Module Instruction

Manual.

AUX Out

Provides connections for a booster amplifier or

tape recorder.

The input impedance of the equipment should be of more than 10k ohms.

Power Amp In

Connect to accessory equipment.

Preamp Out

Connects to a signal processing equipment such

as a limiter, an equalizer, etc. The input

impedances of the equipment should be of more

than 600 ohms.

Bridging Input/Output

This terminal is used as a mixing bus. Mixing is achieved when the similar terminal of another amplifier is connected to this terminal. The output

level taken from this terminal is independent of Master Volume Control, Bass and Treble

Controls so that the terminal can also be used as

recording output.

The input impedances of the equipment to be

connected here should be of more than 10k

ohms.

Remote Volume Control Terminals

Connecting a 10k linear taper potentiometer across these terminals will allow remote control

of preamplifier output.

Mute terminals

Mutes input signals fed to plug-in modules

employing muting function by short-circuiting at these terminals.
