Setting the Rear Output Level
Before setting rear level controls, disconnect both the front output and the
subwoofer output and follow the directions below
.
1.
Turn the output control level to the minimum setting.
2.
Turn the amplifier gain controls to the minimum setting.
3.
Turn the source unit on and increase the volume until distortion is heard,
then reduce volume to just below this point.
NOTE: This is the maximum usable musical signal for this source unit. turning the volume beyond this point will
increase noise and distortion without an increase in musical signal. If you can increase the source unit volume to
maximum without audible disortion, raise the output level controls slightly and begin again.
4.
With the amplifier gains still at minimum and the source unit set at
maximum volume without distortion, raise the rear output level control until
distortion is heard, then reduce gain to just below this point. This is the
maximum output level for this system. For best performance, do not increase
beyond this point.
Setting the Sub Output Level
1.
Make sure all ouputs are connected and the front and rear output levels are
set correctly. Unplug the Remote Sub Level control cable.
2.
Be sure the sub output level and amplifier gains are at their minimum
settings.
3.
With the volume set at a medium level, slowly increase the sub level
control to the point where the subwoofer volume blends with the system.
4.
If maximum sub output level does not provide enough subwoofer volume,
slightly increase the subwoofer amplifier gain until desired level is reached.
5.
Fine tune the bass response using the Sub Boost Controls.
6.
Plug the Remote Sub Level Control cable back into the QA3X crossover.
Setting the Sub Boost Level
1.
Initially set the sub boost level to the minimum setting (i.e. 0dB).
2.
Listen to a variety of music styles (e.g. Rock, Rap, etc.) and slowly
increase the Sub Boost control until a noticeable increase in low bass
response is perceived.
3.
Slowly adjust the Sub Boost Frequency control (up or down) to realize the
best bass response.
CAUTION: This feature can make a subwoofer put out more energy at very low frequencies. Be cautious with this
control because with too much boost at low frequencies the power handling of the subwoofer will be decreased.
This is a subjective setting and will depend on your personal listening preferences. If you hear a “pop” (due to
over-excursion), lower the Sub Boost to prevent speaker damage. If the system sounds muddy and distorted (due
to amplifier clipping), lower Sub Boost to avoid shutdown from overheating.
