Installation, Set Up & Configuration

11

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
configuration. 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
proceeding, or consult the speaker’s
manufacturer.

4. Connections to a subwoofer are made
via a line level audio connection from the
AVI250 

î

to the line level input of a

subwoofer with a built in amplifier. If a
passive subwoofer is used, the connection
first goes to a power amplifier, which will
be connected to one or more subwoofer
speakers.

5. If an outboard multichannel digital
audio adapter is used, connect the six
outputs of the adapter to the 

inputs 

∆

. 

Video Input and 
Output Connections
Video connections are made in a similar
fashion to those for audio components.
Again, the use of high quality
interconnect video cables is
recommended to preserve signal quality.

1. Connect the VCR’s audio, video and
“S” Video OUT jacks to the 

jacks

ACFHJL

on the rear panel. The

audio, video and “S” video IN jacks on
the VCR should be connected to the 

jacks 

BDEGIK

on the AVI

250.

2. Connect the audio, video and “S” video
outputs of a satellite receiver, cable TV
converter or television set to the 

jacks

MNO

.

3. Connect the audio, video and “S” video
outputs of a Laser Disc player to the 

jacks 

PQR

. If your LD player has a

coax digital output for 44.1kHz PCM
audio, you will obtain higher sound
quality by connecting that output to the

jack 

S

.

4. Connect the 

TU

jacks on 

the AVI250 to the video or “S” Video
inputs of your television monitor or video
projector. 

5. There is no mix or change between
”Video” (composite) and ”S” Video
signals inside the AVR70 and no system
selection. If watching to both signal
systems, both 

jacks 

P 

and

Q

must be connected to the TV Monitor. The
”On Screen” menus are visible only on
the ”Video” Output, not on ”S”Video.

System and Power Connections

The AVI250 is designed for flexible use
with external control components and
power amplifiers. These connections are
easy to make during an initial
installation, or at a later date should you
choose to upgrade your system.

Remote Control Expansion
If the unit is placed behind a solid or
smoked glass cabinet door, the
obstruction may prevent the remote
sensor from receiving commands. In this
event, an optional remote sensor may be
used. Connect the output of the remote
sensor to the 

jack

√

. 

If other components are also prevented
from receiving remote commands, only
one sensor is needed. They may use this
unit’s sensor or a remote eye by running
a connection from the 

jack 

∑

to the Remote In

jack on Harman Kardon or other 
JR-code-compatible equipment. 

External Audio Power 
Amplifier Connections
Using the 

jacks 

˙

,

connections may be made to external
power amplifiers. To make these
connections, remove the jumpers between

and 

, and save

them for future use. Connect the 

of the channels to be connected to

external amplifiers to that amplifier’s
inputs. Volume will still be controlled by
this amplifier.
