° 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 2Q or greater. When
multiple speakers are to be connected,
ensure that the combined impedance is 2Q
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 4Q or greater. When
multiple speakers are to be connected,
ensure that the combined impedance 4s 4Q
or greater. :
The rated input of the speakers should be
no less than the maximum output of the
amplifier. Otherwise malfunction may
result.
