6. SPEAKERS TERMINALS x 8
7. RS232 Connector.
8. IR IN & IR OUT
The XG is equipped with 4-circuit plug-
able
Terminal Blocks allow quick
connections of the internal amplifiers to
stereo pairs of speakers in the various
zone rooms. They accept wire sizes for
14 to 28 AWG. The following describes
the connections for Bridge and 2 CH ope
rations;-
XG can be hooked to a control system
through the RS232 connector. The XG
can be hooked up to USB Hub or
Ethernet Switch through RS232 to USB
or RS232 to Ethernet adaptor. Through
the RS232 connector the control system
can turn XG ON or OFF. For details of
Commands, please refer to appendix I.
IR signal from rooms or IR OUT of other
units can be connected to the 3.5mm mini
IR IN jack on the rear panel of XG. So,
XG can be controlled by the IR remote
control in each room through IR sensor.
There is IR OUT as buffered output of IR
IN for controlling units hooking up to XG
or operating as daisy chain for the IR
signal passing through the system.
2 CH MODE.
BRIDGE MODE.
When the MODE SWITCH
of the XG are set to 2 CH operation,
simply
connect the wires from L
loudspeakers to the L sides of speaker
terminal blocks (marked - and +) of CH-A
to CH-H and R loudspeakers to the R
sides of speaker terminal blocks (marked
- and +) of CH-A to CH-H.
Make sure
that the red terminal on each loudspeaker
is connected to the corresp
terminal on each speaker terminal block
and likewise for the black terminal on
each loudspeaker to each - terminal on
each speaker terminal block .
When the MODE
SWITCHES are set to BRIDGE mode
operation, only the + terminals on the
speaker terminal blocks of XG are used.
For this mode of operation, connect the
red terminal of the each speaker to the L+
terminal of each CH speaker terminal
block and the black speaker terminal to
the R+
terminal of each CH speaker
terminal block.
NOTE: The XG amplifier is normally used
in Bridge or 2 CH
modes for all CH A
through CH H. However, it can also can
be set to operate as some Channels for
2CH and other channels for bridge mode.
So the XG will be capable of driving some
8 ohm loudspeaker at 100 watts and
other 4 ohm loudspeakers at 50 watts per
channel. To set the XG in this mode of
operation,
please consult your AMC
dealer.
9. AUDIO SENSE/TRIGGER/CONSTANT
SWITCH
The remote power switch is located on
the back panel of the AMC XG and
provides the following functions;
When the remote power
switch is set in the AUDIO SENSE
position, the XG is turned on or off
automatically, depending on the audio
signal level at the inputs. With an audio
signal greater than 10 mV at any of the
four stereo inputs of XG, the amplifier will
automatically turn on. If the signal level
drops below this level, the amplifier will
remain on for a period of approximately 5
minutes before it automatically reverts to
standby mode.
Please note that when AC power is first
applied to the XG while the remote power
switch is in the AUDIO SENSE position,
the amplifier will automatically turn on,
even
without an audio signal being
present at any of the audio inputs.
However, after approximately 5 minutes,
the amplifier will revert to standby mode,
assuming no signals are present at any of
the inputs.
