Portable Full Range Sound System TRIO LA 6/10
Volume setting of the system is made by means of the three LEVEL
knobs on top of the subwoofer:
- Left satellite is GAIN LEFT
6
6
- Right satellite is GAIN RIGHT
- Subwoofer is GAIN SUBWOOFER
3
Before switching power on and proceed to system setting, make sure that
all three knobs are completely turned counterclockwise, at level 0, and that the mixer output is set so that the peaks level
stays about within 0 e +3 dB.
Set first the satellites volume alone and then the subwoofer volume alone.
Satellites Volume setting
Switch power on and begin to turn clockwise the satellite GAIN knobs
to flash shortly for less than 1 second.
This is the optimal level being connected to a mixer sending to MAIN a signal with level peaks within 0 and +3dB.
Now listen to the satellites with this output level; if you detect distorsion or saturation of the signal (i.e of microphone) check
the possibility of reducing the level of the signal concerned at his source, otherwise try to slightly lower the mixer's main
otput. Should this not be enough, reduce the satellites volume until you have an optimal sound.
Memorize the knobs setting.
Sub Volume setting
After having memorized the knobs setting LEFT e RIGHT, take them back to 0 and begin now to turn clockwise the
SUBWOOFER GAIN knob
3
until the correspondent PEAK led begins to flash shortly for less than 1 second.
This is the optimal level being connected to a mixer sending to MAIN a signal with level peaks within 0 and +3dB.
Now listen to the Sub with this output level; if you detect distorsion of basses, turn slightly the knob back counterclokwise.
Final system setting
Bring the three knobs at the optimal level you have checked and listen to the complete system, again at the mixer
main level peaks between 0 and +3 dB.
If you detect to much basses compared with satellites output, turn slightly back the SUB LEVEL knob.
If you detect instead not enough basses, turn slightly back the setellites LEVEL LEFT and RIGHT knobs.
As a general rule , the output level of the mixers should be set so that the sound peaks remain between 0 to +3 dB
about. When the system TRIO MASTER gets in the two Line In (10 and 11) a signal with that amplitude and it is
set as explained above, it grants the maximum performance in terms of maximum undistorted amplification (at clip
limit) and in this conditions you get the maximum possible sound pressure (SPL).

When STEREO is selected, the system sends to the Right and Left channels the
correspondent Right and Left input signals.
When
MONO is selected,
the LEFT input signal, so one complete system per channel can be used..
