Listening Adjustments
After further checking to ensure that all connections have been correctly made, push the AC power
switch of the Adp-3 to turn on the unit and turn on the pre-amplifier/amplifier. You now need to adjust the
sound balance between the main and sub-speakers as follows:
1. Turn the VOLUME control at (6) to a minimum.
2. Select position 2 of the MODE control at (3).
3. Adjust the volume control on your main amplifier so that
the sound level from the front speakers is a little below that at
which you would listen to for ordinary 2-channel stereo
4. Turn up the VOLUME control (6) of the Adp-3 slightly and
check to ensure that sound is coming from both sub-speakers.
5. Increase the VOLUME of sound from the sub-speakers to a
level where the best SuperStereo effect is had. Usually, this is
the point where the sound level from the sub-speakers is about
the same or slightly greater than that from the front speakers.
Continue to adjust the sound levels from the front and
sub-speakers to get the most pleasing SuperStereo sound.
6. After adjusting the sound balance to your liking, try out
different positions of the MODE (3) control and choose the one
best suited to your room acoustics, the nature of the recording
and your own personal preferences.
7. You can adjust the overall sound level using the volume
control of the pre-amp or integrated amplifier which now
becomes the master volume control.
Mode Control
Polarity Adjustment
The polarity switch at (4) on the front panel changes the po-
larity of the sub-speakers. Choose the position which gives
the fullest and most natural bass.
Overload Indicator
Should this indicator blink more than occasionally, turn down
the volume of your main amplifier and the Adp-3 to a minimum
and select the LOW position of the INPUT SENSITIVITY
switch at (8) on the rear panel. Then re-adjust the volume
controls to your preferred listening levels.
The MODE control allows a choice of SuperStereo
characteristics.
Typical positions are:
MODE 1 for rock and jazz, MODE 2 for classical music and
MODE 3 for church music.
The 3 different delay patterns for SuperStereo allow a closer
match to the performing or recording venue to be obtained.
l
Position 1 has time delays for a small hall or intimate jazz
club. It can also be used when listening to solo instruments or
a group of performers in a small hall.
l
Position 2 is appropriate for venues rather larger than 1
and for many users this will be the position used most often.
l
Position 3 is for large halls. The choice of mode will also be
influenced by the conditions of the recording (or broadcast)
so that music played in an empty reverberant hall may sound
more natural when a lower mode position is selected. When
listening to radio plays, news broadcasts and other spoken,
non-musical material, you should turn the volume of the Adp-3
to a minimum.
