Monitor
VGA monitor connection.
Ethernet
Ethernet port for connecting to a network (see the ‘Networking your
640H’ section of this manual for more information).

IR (Infra Red) Emitter In/Out
In - Allows modulated IR commands from multi-room systems to be
received by the unit. Commands received here are not looped out of
the Control Bus (they are looped out of IR Out).
Out - Loop out of IR modulated commands. Also allows the unit to
generate IR commands (for future use).
RS232
For custom install use.

Control Bus
In - Allows un-modulated commands from multi-rooms systems or other
components to be received by the unit.
Out - Loop out for control bus commands to another unit.
Toslink Optical Digital output
Use to connect to the input of a separate DAC or digital recording
machine. Use a high quality TOSLINK fibre optic interconnect cable
designed specifically for audio use.
S/P DIF Co-axial Digital output
Use to connect to the input of a separate DAC or digital recording
machine. To obtain best results, use a high quality 75 ohm digital RCA
interconnect cable (not one designed for normal audio use).
Audio In/Out
In - Connect to the line level output terminals of a source device for
recording (ie CD input or Aux input etc).
Out - Connect to the line level input terminals on your amplifier.
Power On/Off
Switches the unit on and off.
Mains Voltage Selector Switch
Switches the mains voltage between 115V and 230V. For use by
installer/dealer only.
AC power socket
Once you have completed all connections to the amplifier, plug the AC
power cable into an appropriate mains socket. IMPORTANT - Do not
remove the power cable without switching the 640H off first.
