LED Limiter: Lights up when the limiter circuits start protecting the woofer. The limiter does not
affect the signals on the XLR OUT.
Detect: When the input signal is above – 20 dB it lights green. If the line signal increases to
0 dB it turns red.
The protection circuit also measures signal levels inside the subwoofer amplifier. If
the level calibration is turned clockwise and the signal in one of the measuring
point surpass –20 dB.
Protection: Switch on the subwoofer, and the LED turns red, and for the next 5 seconds the
protection circuit checks the amplifier. When everything is all right, the protection
circuits switch the signal- and speaker relays on.
LEVEL Calibration: Adjustment of the subwoofer level.
Sensitivity: Level attenuation of input signal.
–10 dBm consumer level signal
