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.

When an external amplifier is used for
the front channels, the AVI250’s rear
channel outputs and a passive (non-
powered) subwoofer may be reconnected
to this unit’s front channel amplifiers for
higher power output. To make these 
connections, follow the diagrams on 
this page. Using short RCA to RCA
jumpers, connect the left and right

jacks to the left 

and right 

jacks. 

A subwoofer may be connected by 
connecting the 

to the 

. 

If these connections are used, changes
must be made to the speaker connections.
Connect the left and right surround
speakers to the speaker terminals labeled

˚¬

and the passive subwoofer

to the speaker terminals labeled

ø

. 

NOTE: When external power amplifiers
are used, the center channel speakers
should receive at least as much amplifier
power as the front left and right speakers. 

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 amplifiers (not more than
50 W each).

The 

†

outlet 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.

Most devices with electronical power
switch may only switch on to standby
mode.

The 

ü

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
non-switched 230 volt AC wall outlet.
Note that the ring surrounding the Power
Switch 

^

will turn amber. You’re 

almost ready to enjoy the AVI250!

Remote Control Programming & Operation

13

This product is equipped with a powerful
remote control. As supplied, it will operate
the unit, as well as most tuners, CD
players and tape decks manufactured by
Harman Kardon. In addition, it is
preprogrammed with the remote codes to
operate VCRs, LD players and TV sets that
are based on the popular RC-5 control
code system. If your equipment requires
different codes, it may be programmed to
copy the codes from most infra red
remotes. 

Loading Batteries
The life of the batteries for the remote
control is about one year in normal
operation. If the green

x

indicator does not flash when remote
buttons are pushed, that is an indication
that the batteries need to be replaced.
Don’t simply through old batteries away
but recycle them or return to your dealer.

To change the batteries:
1. Remove the back cover by sliding it in
the direction of the arrows. 

2. Remove the old batteries and insert
fresh AAA type cells. Be certain to observe
the correct polarity by noting the (+) and
(–) marks on both the inside of the case
and on the battery cells. It is
recommended that both batteries be
changed at the same time.

3. Close the cover until it clicks shut.

NOTE: It is important that the batteries
be replaced within ten minutes after the
old batteries are removed to avoid losing
any remote codes that have been
programmed into the remote’s memory.

Remote Control Range
The remote will operate at a range of up
to 5 meters from the unit, when the
batteries are fully charged. The remote
will also operate at an angle of up to 30°
to either side of the unit.

Always point the remote transmitter at the
front of the unit when issuing
commands. If you find that remote
commands are not being received by the
remote, it may be necessary to use a
remote IR sensor.

Remote Programming

Programmable Keys
Most of the buttons on the remote control
that may be user programmed to new
functions to operate virtually any
component in your system. Ten CANNOT
be programmed with a new code, as they
control high level functions of the AVI
250. These keys are 

,

, and the eight source

input keys: 

, 

, 

, 

,

, 

, 

and 

. 

Programmable keys are divided into two
groups. Some keys may be programmed
with a separate function for each of the
inputs. Thus, these keys may change their
code when the input source is changed.
(i.e. The 

key may transmit a

different code when 

is selected as

opposed to when 

is selected.) The

keys that may be programmed with
multiple codes are the following:

Another group of keys may only be
programmed with one remote code. The
code contained in these keys remains the
same regardless of the source selection.

WARNING: These keys transmit codes
that are vital to the operation of the
product. It is not recommended that they
be programmed with alternative codes, as
it may then be impossible to operate
certain functions of the amplifier.

To program the remote, you need the re-
mote of the device, the functions of which
shall be programmed. Note that it is not
necessary to program all keys, only those
that are required to operate the subject
device. Keys not programmed will retain
the codes preprogrammed at the factory.

1. Slide 

a

switch at the top

left corner of the remote to the right so
that it is next to 

.

2. To program one of the multi-function
buttons press the source button (i.e. 

,

, etc.) you wish to have this function

associated with. If you are programming
a single function key, proceed to the next
step.

3. Press the button on the AVI250-remote
that is to be programmed. Note that the

y

LED will illuminate.

4. Place the remote head to head with the
remote control whose function is being
learned. The two remotes should be no
more than 20 centimeters apart.

5. Press and hold the button on the other
remote corresponding to the function to
be memorized until the 

LED

on the AVI250 remote starts to blink.
When the LED goes out, release the
button on the transmitting remote. The
function code has been successfully
captured by the AVI250-remote.

NOTE: If both LEDs flash during a
programming operation, it indicates that
the remote’s memory is full or that the
remote codes from the transmitting
remote are not compatible with the unit’s
signal format.

6. Continue to program any additional
remote commands required using steps
2 through 5. When you have finished
programming the remote, slide the

switch to the left so that it

is in the

position.

Clearing the Remote Memory
In normal operation, codes for a new
device may be programmed “over” the
codes that have been previously
programmed into the remote. It is also
possible to clear the memory for
individual keys, or for the entire remote.
When a memory position is cleared, the
remote will return to the original factory
preset command.

To clear the memory for a specific
individual key location, put the

switch in the 

position. Press the 

b

button and the button to be cleared at the
same time. Both the 

and

indicators will light

momentarily. When the lights go out, the
memory has been cleared of the user
programmed code and returned to the
factory preset. Return the 

a

switch to the 

position when you

are finished. 

To clear the remote’s entire memory 
and return all keys to their factory preset
commands first put the 

a

switch in the 

position. Then press

the 

button 

b

and

confirm that the 

indicator 

y

has illuminated. While continuing to
press the 

button, press and

hold the 

b

button until the

indicator goes off for about 3

seconds. It will then blink twice. Then
release the two buttons. This indicates
that the memory has been cleared of any
user programmed commands and that
the original commands have been
restored. Slide the 

switch

back to the 

a

position to return

the remote to normal operation.
