a
GND screw terminal
Connecting the source device chassis to the GND terminal of the
unit may reduce noise in the signal.
Note
The ground is not a safety ground.
b
IR IN/OUT jack
Connection: 3.5 mm monaural mini-plug
For connecting to an external remote control device and
inputting/outputting remote control signals. The output with pass-
through function is enabled even in standby mode.
c
AMP 1– 4: IN/THRU. OUT jacks
Connection: stereo RCA plug (L/R)
IN:
For connecting to an audio playback device such as a CD
player (analog out jack) and inputting audio signals in AMP1–
AMP4.
THRU. OUT:
For outputting analog audio signals input in
AMP 1– 4 : IN jacks by pass-through function. The output is
enabled even in standby mode.
d
AUTO STANDBY switch
Enables/disables the auto-standby function.
OFF
: does not set the unit to standby mode automatically.
ON
: sets the unit to standby mode when there are no operations
for 8 hours.
AUDIO SENSE switch
Enables/disables the audio sense function that detects analog
audio signals input in AMP 1– 4 : IN.
OFF
: disables the audio sense function.
ON
: detects the input in AMP 1– 4 : IN, and thereby turns
AMP1– AMP4 to on.
Note
Unplug the unit’s power cord from the AC wall outlet before
changing the AUDIO SENSE switch setting.
AUDIO SENSE MODE switch
Selects the audio sense mode that determines the amount of
time required between input of analog audio signals being
detected and analog audio signals being output.
STANDBY
: outputs analog audio signals about 7 seconds after
detecting the input of them. This setting reduces the unit’s
standby power consumption..
ACTIVE
: outputs analog audio signals within 1 second after
detecting the input of them.
e
TRIGGER IN 1– 4 jacks
Connection: 3.5 mm monaural mini-plug (Tip: + / Sleeve: -)
For inputting trigger signals (DC 12 V). Each AMP is powered on
by inputting “High”.
f
TRIGGER OUT 1– 4 jacks
Connection: 3.5 mm monaural mini-plug (Tip: + / Sleeve: -)
For outputting trigger signals (DC 12 V) iby powering on each
AMP.
g
NORMAL/BRIDGE switch
Selects NORMAL/BRIDGE connection of speakers. This switch
is normally set to NORMAL. Change the setting to BRIDGE only
when the speaker is used in bridge connection.
Note
Unplug the unit’s power cord from the AC wall outlet before
