• Stereo Connections:
• 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 2
amplifier, stereo connections are used.
The speakers to be connected should
have an impedance of 2
Ω
or greater.
When multiple speakers are to be
connected, ensure that the combined
impedance is 2
connected, ensure that the combined
impedance is 2

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.)

#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.
