Input terminal

Electrically-balanced input terminals. The 3P screw terminal is connected in parallel with a balanced phone jack.

Also, the input can be converted into a transformer- balanced input using an optional matching transformer

LT-101.

Level control switch

Usually, set this switch to OFF. When an interface unit is connected, shifting this switch to ON permits external input level adjustment.

[Precautions]

No sound is output if the level control switch is set to

ON without connecting an interface unit. Confirm the switch position before switching on the power. Be sure to switch off the power when changing control switch

settings.

Control I/O terminal

Connects to the an interface unit when monitoring or

performing remote controls from external equipment. For details, contact your TOA dealer.

[Precautions]

No other unit other than an interface unit must be

connected to the terminal. Be sure to switch off the

power when connecting an interface unit.

Output mode selector switch

Selects STEREO, BTL or PARALLEL mode.

STEREO mode

Channels 1 and 2 are operated independently. (The

unit functions as a normal stereo amplifier.) Channel

1 input signal goes to Channel 1 output, and Channel 2 input signal goes to Channel 2 output.

BTL mode

The unit functions as a monaural amplifier with 1 input and 1 output. Channel 1 input signal goes to both output BTL (+) and (-) terminals.

PARALLEL mode

The unit functions as a monaural amplifier with 1 input and 2 outputs. Channel 1 input signal goes to

the outputs of both Channels 1 and 2. Input signal

levels of channels 1 and 2 can be set independently.

[Precautions]

Use only Channel 1 input terminal when in BTL or

PARALLEL mode. Do not use Channel 2 input terminal.

Confirm the position of the output mode selector switch

before switching on the power. Be sure to switch off the

power when changing mode switch settings.

Output terminal (with a protection cover)

Connect speaker cables to these terminals. Because the upper terminals are connected in parallel with the lower terminals, both terminals can be used simultaneously. Refer to p.8 for speaker cable connections.

[Precautions]

Be sure to switch off the power when connecting the speaker cables. Never connect two amplifier outputs in parallel under any circumstances.

Grounding terminal for signals

When the power amplifier is connected to other equipment, grounding sometimes creates a loop,

producing hum noise. This loop can be cut and noise reduced by removing a shorting metal piece connecting two terminals.
