This is a 4 channel amplifier including 2 stereo amplifiers in a body. One
amplifier is referred to as amplifier A and the other is amplifier B. This unit
is compatible with a large variety of systems by combining the switches and
functions described in the following.
1 Fuse (25 A × 3)
2 Battery terminal
3 Ground terminal
4 Power control terminal
Controls the unit ON/OFF.
NOTE
Controls the unit power. Be sure to connect it with all the systems.
5 Speaker output terminals (A.ch/B.ch)
• 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
9
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.
6 RESET button
Resets the microprocessor of the unit.
7 LINE IN terminal
8 LINE OUT terminal
Outputs the audio signal set in DSP settings (stereo or center speaker/
subwoofer).
9 Power indicator
Lights when the POWER switch is turned On.
The indicator flashes several seconds when the POWER switch is turned On
or when the Protection function is activated.
0 MODE switch (A/B/LINE OUT)
This switch selects the channel set in DSP settings (A, B, LINE OUT).
! Control knob
Allows you to switch between and determine Menu System items.
@ DISP switch (SET/INFO)
• INFO position:
Sets <Status Information Display and Settings> (page 7).
• SET position:
Sets <DSP Settings> (page 8).
# INPUT SENSITIVITY control (A.ch/B.ch)
Set this control according to the pre-output level of the center unit
connected with this unit.
See <Input Sensitivity> (page 10) for details on setting.
NOTE
• For the LINE OUT level, refer to the <Specifications> in the instruction
manual of the center unit.
• When A is selected with the INPUT SELECTOR switch, the control portion for
cannot be used.
$ INPUT SELECTOR switch
This switch selects the input method of the signals to be amplified by
amplifiers A and B.
• A B position:
Amplifies both of the signals input to amplifiers A and B.
• A position:
Amplifies only the signal input to amplifier A with both amplifiers A and B.
% OPERATION switch (A.ch/B.ch)
The amplification methods of the signals input to amplifiers A and B can be
selected independently according to the setting of this switch.
• STEREO position:
The amplifier can be used as a stereo amplifier.
• MONO (Lch) position:
Amplifies the signal input from the left side only. Set to this position and
make bridged connections to use as a high-power monaural amplifier. (The
input right signal is not output.)
