This is a normal step to
adjustment, for more
professional adjustment you
should have a professional
person to do that.
For high power system, the
Power-on order is very
important,not in the order is
likely to damage the
equipment.Therefor we
suggest that you use the
sequence power device.
Music Audition
Adjust the volume from very small to loud slowly, after you confirm
the sound is normal then make it more louder. When the speaker
output is close to its limit, the CLIP light will lights up and you
should turn down your volume now, don't let the CLIP lights on long
time, it means over load, may damage the system.
This step should operated by
professional person, if you
don't know how to do, please
be careful!
