Installation, Set Up & Configuration
NOTE: While most speaker manufactur-
ers adhere to an industry convention of
using black terminals for negative and
red ones for positive, some manufactur-
ers may vary from this configuration. To
assure proper phase, and optimal perfor-
mance, 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 @ 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 6 CH.
Direct Input 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 intercon-
nect cables is recommended to preserve
signal quality.
1. Connect the VCR's audio, video and
"S" Video OUT jacks to the VCR IN
jacks ENC GAG) EG on the rear panel.
The audio, video and "'S" video IN jacks
on the VCR should be connected to the
VCR OUT jacks DIEEIMIES on
the AVI250.
2. Connect the audio, video and "S"
video outputs of a satellite receiver, cable
TV converter or television set to the TV
jacks MM.
3. Connect the audio, video and "S"
video outputs of a Laser Disc player to the
LD jacks (fey. 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
LD Digital In jack &.
4. Connect the TV MON
jacks on
the AVI250 to the video or "'S" Video
inputs of your television monitor or video
projector.
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 installa-
tion, 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 obstruc-
tion 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 Remote Cont. IN 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 REMOTE
CONT. OUT jack @ to the Remote In
jack on Harman Kardon or other com-
patible equipment.
External Audio Power Amplifier
Connections
Using the PRE OUT jacks @, connec-
tions may be made to external power
amplifiers. To make these connections,
remove the jumpers between PRE-OUT
and MAIN IN, and save them for future
use. Connect the PRE-OUT of the chan-
nels to be connected to external ampli-
fiers to that amplifier's inputs. Volume
will still be controlled by this receiver.
When an external amplifier is used for
the front channels, this amplifier's rear
channel outputs and a passive (non-
powered) subwoofer may be reconnected
to this unit's front channel amplifier for
