SYSTEM CONFIGURATION
When the
CHANNEL ADJUST
menu first
appears the test tone is off. If desired, you may imme-
diately use the
⁄
/
¤
Navigation Button
n
to
select any channel for adjustment using an external
source, such as a test disc, from which to judge the
output levels. After the
›
cursor is pointing to the
channel to be adjusted, press the
‹
/
›
Navigation
Button
o
to raise or lower the output level.
However, before proceeding with any manual adjust-
ment we recommend that you first use the AVR’s
internal test tone generator and automatic sequencer
to send a tone to each channel so that you may verify
that all speaker connections have been properly made.
To turn the test tone on and have it automatically cir-
culate among the channels where a speaker has pre-
viously been configured (see page 20), press the
⁄
/
¤
Navigation Button
n
until the
›
cursor is
pointing to the
TEST TONE
line on the menu.
Next, press the
‹
/
›
Navigation Button
o
until
AUTO SEQ
is shown in highlighted video. At this
time the test tone will immediately begin to circulate
clockwise around the room, playing for two seconds in
each speaker before switching to the next speaker
position. The
›
cursor will blink next to the active
speaker to indicate which speaker the sound should
be coming from.
As the test noise circulates, listen to make certain that
the sound comes from the speaker position shown in
the
Lower Display Line
. If the sound from a
speaker location does NOT match the position indicated
in the display, turn the AVR 235 off using the
Main
Power Switch
1
and check the speaker wiring or
connections to external power amplifiers to make cer-
tain that each speaker is connected to the correct out-
put terminal.
After checking for speaker placement, let the test
noise circulate again, and listen to see which channels
sound louder than the others. Using the front left
speaker as a reference, press the
‹
/
›
Navigation
Button
o
to bring all speakers to the same volume
level. When the
‹
/
›
Navigation Button
o
is
pushed, the test noise circulation will pause on the
channel being adjusted to give you time to make
the adjustment. When you release the button, the
circulation will resume after five seconds.
Continue to adjust the individual channels until the
volume level sounds the same from each speaker.
Adjustments should be made with the
‹
/
›
Navigation
Button
n
only, NOT the main volume controls. If you
are using a sound-pressure level (SPL) meter for pre-
cise level adjustment, set the volume so that the meter
reads 75dB on the C-Weighting, Slow Scale.
You may also make these same adjustments with
complete manual control over the channel being
adjusted by pressing the
⁄
/
¤
Navigation Button
n
until the
›
cursor is pointing to the
TEST
TONE SEQ
line on the menu and then using the
‹
/
›
Navigation Button
o
to select
MANUAL
in the highlighted video. In the
MANUAL
mode, the
test tone will also start immediately, but the tone will
only be moved to another channel by pressing the
⁄
/
¤
Navigation Button
o
. When the manual
sequencing mode is active, the tone is turned off by
pressing the
⁄
/
¤
Navigation Button
o
until the
›
cursor is pointing to the
TEST TONE
line and
the
‹
/
›
Navigation Button
o
is then pressed to
select
OFF
.
Using the Semi-OSD System
The output levels may also be adjusted at any time
using the remote control and semi-OSD system.
To adjust the output levels in this fashion, press the
Test Button
i
. As soon as the button is pressed,
the test tone will begin to circulate as indicated earlier.
The correct channel from which the test noise should
be heard will be shown in the lower third of the video
screen and in the
Lower Display Line
¯
. While
the test noise is circulating, the proper channel
position will also be indicated in the
Speaker/
Channel Input Indicators
ˆ
by a blinking letter
within the correct channel.
To adjust the output level, press the
⁄
/
¤
Buttons
n
until the desired level is shown in the display or
on-screen. Once the buttons are released, the test
noise will begin to circulate again in five seconds.
When all channels have the same output level, press
the
Test Button
i
again to complete the process.
If you find that the output levels are either uncomfort-
ably low or high, you may repeat the procedure, but
first adjust the master volume either slightly higher or
lower (but not higher than 0dB) to compensate. Do
not adjust the volume during the procedure, as that will
cause the output levels to be higher or lower for only
some channels, resulting in uneven balance.
To make channel level adjustments to an external
source, rather than using the AVR's internal test tone,
simply press the
Channel Select Button
m
, and
each individual channel and its level offset will be dis-
played on-screen in the semi-OSD display. This is the
equivalent of using the
CHANNEL ADJUST
menu with the test tone set to
OFF
.
NOTE:
Output level adjustment is not available for the
VMAx or Surround Off modes.
Additional Input Adjustments
After one input has been adjusted for Surround mode,
digital input (if any), speaker type and output levels,
go back to the
INPUT SETUP
line on the
MASTER MENU
(Figure 1) and enter the set-
tings for each input that you will use. In most cases,
only the digital input and surround mode will be differ-
ent from one input to the next, while the speaker type,
Night mode and output level settings will usually be
the same and may be quickly entered by entering the
same data used for the original input.
When all settings and adjustments have been made,
press the
OSD Button
v
to return to normal oper-
ation of the AVR.
Once the settings outlined on the previous pages have
been made, the AVR 235 is ready for operation. While
there are some additional settings to be made, these
are best done after you have had an opportunity to lis-
ten to a variety of sources and different kinds of pro-
gram material. These advanced settings are described
on pages 32 and 33 of this manual. In addition, any
of the settings made in the initial configuration of the
unit may be changed at any time. As you add new or
different sources or speakers, or if you wish to change
a setting to better reflect your listening taste, simply
follow the instructions for changing the settings for that
parameter as shown in this section.
Having completed the setup and configuration process
for your AVR 235, you are about to experience the
finest in music and home theater listening. Enjoy!
