PRE-OUT
h
• Connect the SW output to powered
subwoofer.
• The PRE-OUT makes it possible to use
the High Defi nition A/V Receiver as a
pre-amplifi er to external power
amplifi ers for some or all channels.
Connect FRONT L, FRONT R,
CENTER, SURR R, SURR L, SURR-BL,
SURR-BR and SUBW to the respective
channel input of a power amplifi er or
an amplifi er driving the applicable
speakers. Unlike the full range channels,
there is no power amplifi er built-into
the High Defi nition A/V Receiver for a
subwoofer.
UPLOAD (MCU, HDMI), RESET
i
• The MCU, HDMI and RESET switches
are meant for product service purposes.
In the unlikely event that your High
Defi nition A/V Receiver hangs up, you
can press RESET to restore your High
Defi nition A/V Receiver to normal
adjust settings.
IR IN
j
• These mini-sockets accept and output
remote-controlled codes in electrical
format, using industry-standard
protocols, for use with "IR-repeater"
and multi-room systems and related
technologies.
• This input is connected to the output of
an IR (infrared) repeater (Xantech or
similar) or the IR output of another
device to allow control of the High
Defi nition A/V Receiver from a remote
location.
IR OUT 1-2
• Both IR OUT 1 and IR OUT 2 have
dual-features – they can act as an
infrared command repeater or stand
alone as IR OUT. Connect the High
Defi nition A/V Receiver's IR IN to the
IR OUT of ancillary device. Connect
also the High Defi nition A/V Receiver's
IR OUT 1 (or IR OUT 2) to another
device with IR IN feature. With this
setup, the High Defi nition A/V Receiver
acts as an "IR-repeater" allowing the
device connected to the High Defi nition
A/V Receiver' s IR IN control or
command of the other device linked to
the High Defi nition A/V Receiver's IR
OUT 1 (or IR OUT 2).
• As a stand alone IR OUT, connect IR
OUT 1 (or IR OUT 2) to the IR IN of
an ancillary device. Direct the ancillary
device's own remote control to the
High Defi nition A/V Receiver's infrared
receiver to command or control the
linked unit.
+12V TRIGGER OUT
k
• The +12V TRIGGER OUT is used for
controlling external device that is
equipped with a +12V trigger input.
This output will be 12V when the
High Defi nition A/V Receiver is ON
and 0V when the unit is either OFF or
in standby. This output can drive a load
up to 150mA at 12V. (see ' Adjust
settings' > 'Settings menu' > [Trigger
setup])
