17 INSTALLATION AND CONNECTIONS
Installation and Connections
IMPORTANT NOTE: Any cables run inside walls
should be CL3/FT4-rated or carry any other certi-
fication that is required by the NEC or state and
local building and electrical codes. To avoid inter-
ference, audio and speaker cables should not be
parallel to, or run in the same conduits or path
with, AC cables. If you have any questions about
multiroom wiring, consult your dealer, custom
installer or low-voltage electrical contractor.
External Audio Power Amplifier
Connections
If desired, the AVR 510 may be connected to
optional, external audio power amplifiers or
used with equalizers or speaker systems that
require connection between the preamp and
amplifier sections of a receiver.
To make these connections, remove the jumpers
that connect the
Preamp Out jacks ¤ and
Amplifier In jacks ⁄ for the channels to be
used with external devices. Store the jumpers in
a safe place so that the AVR 510 may be used
in its normal mode at a future date, if desired.
When an external amplifier is used, connect the
Preamp Out jacks ¤ to the inputs on the
amplifier.When an equalizer or speaker proces-
sor is used, connect the
Preamp Out jacks ¤
to the inputs of the processor, and connect the
outputs of the processor back to the
Amplifier
In
jacks ⁄ on the AVR 510. Note that when
external amplifiers or devices are used, the vol-
ume control is still controlled by the AVR 510,
although additional volume controls on the
external device may impact the volume settings
and output levels from the AVR 510.
External Audio Decoder Connection
To provide for ultimate flexibility, the AVR 510
may be used in conjunction with optional,
external decoders for digital audio systems
other than the AVR 510’s own built-in Dolby
Digital and DTS decoding system or with DVD
players using the DVD Audio Format. If an
external decoder is used, connect the output
jacks of the decoder to the
6-Channel Direct
Inputs
ª, making sure to match channels.
These jacks may also be used for connections to
devices such as DVD players or High Definition
Television (HDTV) sets or decoders that feature
built-in digital surround decoders. Although the
digital decoding system in the AVR 510 will typi-
cally provide audio performance that is superior
to other decoders, you may use these jacks to
provide an additional 6-channel input for connec-
tion to a DVD player or HDTV set with a built-in
decoder and discrete 6-channel analog outputs.
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 equipment such as power ampli-
fiers. The total power draw to each outlet may
not exceed 100 watts.
The
Switched AC Accessory Outlet fl will
receive power only when the unit is on. This is
recommended for devices that have no power
switch or 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 outlets, and cannot be fully turned on
using the outlet alone without a remote control
command.
The
Unswitched AC Accessory Outlet ‡
will receive power as long as the unit is
plugged into a powered AC outlet.
Finally, when all connections are complete, plug
the power cord into a nonswitched 110-volt AC
wall outlet.You’re almost ready to enjoy the
AVR 510!
