18 INSTALLATION AND CONNECTIONS
INSTALLATION AND CONNECTIONS
programming for control be made by a trained installer
or technician familiar with the equipment being used.
The RS-232 port may also be used as an access
point through which the AVR 635’s operating system
and surround mode memories may be updated via
connection to a compatible computer. At the time
that any upgrade is available, instructions for making
the connection and installing the upgrade will be
available through the Product Support area of the
Harman Kardon Web site at harmankardon.com.
The physical connection to the AVR 635’s RS-232
port is a standard D-SUB 9 connection,
but to ensure
compatible and proper operation,
specific software
commands and pin wiring schemes may be required.
AC Power Connections
This unit is equipped with two accessory AC outlets.
They may be used to power accessory devices, but
they should not be used with high-current draw equip-
ment such as power amplifiers. The total power draw
to each outlet may not exceed 100 watts.
The
Switched AC Accessory Outlet ⁄ is powered
only when the unit is on. This is recommended for
devices that have a mechanical power switch that may
be left in the “ON” position.
NOTE: Many audio and video products go into a
Standby mode when they are used with switched out-
lets. This type of product may not operate properly
when used with the switched outlet.
The
Unswitched AC Accessory Outlet ¤ is
powered as long as the AVR is plugged into a
powered
AC outlet.
The AVR 635 features a removable power cord
that allows wires to be run in advance to a complex
installation so that the unit itself need not be installed
until it is ready for connection.
When all needed
connections have been made, connect the AC
Power cord to the
AC Power Cord Jack ‹.
The
AVR 635 draws significantly more current than
other household devices, such as computers, that use
removable power cords. For that reason, it is important
that only the cord supplied with the unit (or a direct
replacement of identical capacity) be used.
Once the power cord is connected, you are almost
ready to enjoy the AVR 635’s incredible power
and fidelity!
