LIMIT indicator alerts the user that the amplifier output signal is clipping and therefore is being compressed by the built in clip limiter Momentary Bright Red Flashes Indicates that the amplifier is clipping briefly causing overdrive distortion and the internal limiter is reducing gain The MATRIX 1500 employ a sophisticated compressor limiter circuitry which is nearly inaudible at moderate overdrive conditions It is normal to see the occasional flashing of the red LIMIT LED Continuous Bright Red Light Indicates continuous and gross overloading of the amplifier Such overloads are audible and may lead to overheating of the amplifier and shortening the life of the speaker components If the amplifier is grossly overloaded and the red LIMIT LED is on the most of the time the operator should reduce the signal level so that LIMIT LED only flashes occasionally SIGNAL LED INDICATOR The green SIGNAL indicator alerts the operator to the presence of an input signal at the amplifier If there is no indication check the gain settings on the amplifier and increase the gain if necessary Check input connections and audio source for signal If no output persists try a different signal cable from your mixer to the MATRIX 1500 If the green SIGNAL LED remains illuminated without a source connected the amp may need servicing SATELLITE CHANNELS LEVEL CONTROLS Turn the right and left LEVELs control clockwise to increase gain and c
