Block diagram #1 When FILTER is set to LPF, the sound is monaural (L+R).

#2 When INFRASONIC is set to 15Hz or 25Hz, the sound is monaural (L+R). * Note that if OPERATION is set to MONO, Lch is still monaural.

❖SPEAKER OUTPUT terminals

•Stereo Connections:

When you wish to use the unit as a stereo amplifier, stereo connections are used.

The speakers to be connected should have an impedance of 2Ω or greater. When multiple speakers are to be

connected, ensure that the combined impedance is 2Ω or greater for each channel.

•Bridged Connections:

When you wish to use the unit as a high- output monaural amplifier, bridged connections are used. (Make connections to the LEFT channel (+) and the RIGHT channel (-) SPEAKER OUTPUT terminals.)

The speakers to be connected should have an impedance of 4Ω or greater. When multiple speakers are to be connected, ensure that the combined impedance is 4Ω or greater.

2CAUTION

The rated input of the speakers should be no less than the maximum output of the amplifier. Otherwise malfunction may result.

9LINE OUT terminal

These jacks output respectively the signals input to amplifiers A and B. They always output the stereo signals regardless of the position of the OPERATION switch.
