INSTALLATION AND CONNECTIONS

System Installation

After unpacking the unit, and placing it on a solid
surface capable of supporting its weight, you will
need to make the connections to your audio and
video equipment.

Audio Equipment Connections

We recommend that you use high-quality inter-
connect cables when making connections to
source equipment and recorders to preserve the
integrity of the signals.

When making connections to audio source
equipment or speakers it is always a good prac-
tice to unplug the unit from the AC wall outlet.
This prevents any possibility of accidentally
sending audio or transient signals to the speak-
ers that may damage them.

1. Connect the analog output of a CD player to
the

inputs

•

NOTE:

When the CD player has both fixed and

variable audio outputs it is best to use the fixed
output unless you find that the input to the
receiver is so low that the sound is noisy, or so
high that the signal is distorted.

2. Connect the analog Play/Out jacks of a cas-
sette deck, MD, CD-R or other audio recorder to
the

Tape Input

jacks

. Connect the analog

Record/In jacks on the recorder to the

Tape

Output

jacks

™

on the AVR 110.

3. Connect the output of any digital sources
to the appropriate input connections on the
AVR 110 rear panel. Note that the

Optical

and

Coaxial Digital Inputs

may

be used with a Dolby Digital or DTS source or
the output of a conventional CD or LD player’s
PCM (S/P-DIF) output.

4. Connect the

Coaxial

Optical Digital

Outputs

on the rear panel of the AVR 110 to

the matching digital input connections on a CD-R
or MiniDisc recorder.

5. Assemble the AM Loop Antenna supplied
with the unit as shown below. Connect it to the

and

GND

screw terminals

6. Connect the supplied FM antenna to the

(75 ohm) connection

. The FM antenna may

be an external roof antenna, an inside powered
or wire lead antenna or a connection from a
cable TV system. Note that if the antenna or
connection uses 300-ohm twin-lead cable, you
must use the 300-ohm-to-75-ohm adapter sup-
plied with the unit to make the connection.

7. Connect the front, center and surround
speaker outputs

‹›fi

to the respective

speakers.

To ensure that all the audio signals are carried
to your speakers without loss of clarity or reso-
lution, we suggest that you use high-quality
speaker cable. Many brands of cable are avail-
able and the choice of cable may be influenced
by the distance between your speakers and the
receiver, the type of speakers you use, personal
preferences and other factors. Your dealer or
installer is a valuable resource to consult in
selecting the proper cable.

Regardless of the brand of cable selected, we
recommend that you use a cable constructed of
fine, multistrand copper with a gauge of 14 or
smaller. Remember that in specifying cable, the
lower the AWG number, the thicker the cable.

Cable with a gauge of 16 may be used for short
runs of less than ten feet. We do not recom-
mend that you use cables with an AWG equiva-
lent of 18 or higher due to the power loss and
degradation in performance that will occur.

Cables that are run inside walls should have the
appropriate markings to indicate listing with UL,
CSA or other appropriate testing agency stan-
dards. Questions about running cables inside
walls should be referred to your installer or a
licensed electrical contractor who is familiar
with the NEC and/or the applicable local build-
ing codes in your area.

When connecting wires to the speakers, be cer-
tain to observe proper polarity. Remember to
connect the “negative” or “black” wire to the
same terminal on both the receiver and the
speaker. Similarly, the “positive” or “red” wire
should be connected to like terminals on the
AVR 110 and speaker.

NOTE:

While most speaker manufacturers

adhere to an industry convention of using black
terminals for negative and red ones for positive,
some manufacturers may vary from this config-
uration. To assure proper phase and optimal

performance, consult the identification plate on
your speaker or the speaker’s manual to verify
polarity. If you do not know the polarity of your
speaker, ask your dealer for advice before pro-
ceeding, or consult the speaker’s manufacturer.

We also recommend that the length of cable
used to connect speaker pairs be identical.
For example, use the same length piece of
cable to connect the front-left and front-right
or surround-left and surround-right speakers,
even if the speakers are a different distance
from the AVR 110.

8. Connections to a subwoofer are normally
made via a line-level audio connection from the

Subwoofer Output

to the line-level input

of a subwoofer with a built-in amplifier. When a
passive subwoofer is used, the connection first
goes to a power amplifier, which will be con-
nected to one or more subwoofer speakers. If
you are using a powered subwoofer that does
not have line-level input connections, follow the
instructions furnished with the speaker for con-
nection information.

Video Equipment Connections

Video equipment is connected in the same man-
ner as audio components. Again, the use of high-
quality interconnect cables is recommended to
preserve signal quality.

1. Connect a VCR’s or other video source’s
audio and video Play/Out jacks to the

Video 1

Video 2 In

jacks

on the rear

panel. The Audio and Video Record/In jacks on
the VCR should be connected to the
