Installation and Configuration
External Amplifier Connections
The flexibility of the AVR41 permits you to
use external power amplifiers in place of
the unit’s built-in amplifier. If an
external five channel amplifier is used,
remove the jumper pins connecting the
front left/right outputs
a
and the
main amplifier inputs
b
. Connect all
preamp output channels
a c d
to the
appropriate input connections of your
power amplifier. Remove the speaker wire
connections from the receiver and
connect them to the external amplifier.
All other operation of the receiver
remains normal.
NOTE:
Although there are two outputs
for the centre channel, both are identical.
It is also possible to use a higher power
external amplifier for the two or all three
front channels and use the AVR41’s inter-
nal amplifier to power the surround
channels. For this installation remove the
jumper pin connecting the
front
left/right outputs
a
and the
main
amp inputs
b
. Flip the pins so that the
rear outputs
c
are connected to the
main inputs.
Connect the front channel outputs
a
as
shown above, with 3 channel amplifiers
any of the
Center Pre Outs
d
too, to
the appropriate inputs of the external
amplifier, and move the front channel
speaker wire connections from the AVR41
to the power amplifier.
Finally, connect the rear channel speaker
wires to the front left and right speaker
outputs on the AVR41
¤‹
, as shown
on the accompanying diagram.
NOTE:
When using an external amplifier
for the front channels it is highly recom-
mended that the same power be used for
the left, centre and right channels.
NOTE EXTERNAL DECODES
When using an external 5 channel (option
1 above) or 3 channel (option 2) amplifier
it is possible to accommodate external
5.1
Digital Audio Decoders
with cinch
in/outputs for all channels (as f.e. the HK
ADP 303). Connect it between all Preamp
Outs

of the AVR41 and the

channel amplifier (option 1) respectivelly

(option 2). Reduce the Volume control of

playing any 5.1 source.

Center Channel Mode
This setting enables you to tailor the out-
put of the AVR41 to the type of centre chan-
nel speaker in use. Press the
Center
button
^
until the front panel display
indicates the type of speaker used in your
listening environment.
LG CENTR
: Choose this setting if your
centre speaker is a traditional full range
model capable of extended bass response.
Subwoofer output may be low in this mode.
SM CENTR
: Choose this setting if your
centre speaker is a smaller type with limited
bass response. This is the mode used in
most systems.
NO CENTR
: Choose this setting if no
centre speaker is installed.
Rear Channel Setting
This setting tells the AVR41 if rear channel
speakers are in use. Press the
Rear
button
&
until the front panel display indicates
the appropriate condition for your
listening system.
REAR
: Choose this setting if rear channel
speakers are installed.
NO REAR
: Choose this setting if rear
speakers are not in use.
Output Level Calibration
For proper operation in the surround
modes it is important that the level from
all channels be as close to one another as
possible. A small amount of time spent to
properly calibrate the AVR41’s output levels
will enable the unit to deliver all the per-
formance it is capable of within the specif-
ic environment of your listening room.
