1 Gain Bass
This knob adjusts the subwoofer’s volume. When set to the 12 o’clock
position (0 dB /center-notched), the subwoofer’s volume is matched to the
LINEAR active speakers’ levels to achieve a balanced soundscape with an
evenhanded distribution of low and midrange frequencies. If you want to
increase or decrease the subwoofer’s volume, simply rotate the knob to the
left or right (control range +/-6 dB).
2 Power LED (L SUB 1200 A, L SUB 2000 A, L SUB 4000 A)
This LED lights up green when the Power button is set to On and mains
power is provided

This LED lights up red when the power amp’s input signal is too high or a
fault has been detected. The LED briefl y fl ashes red to tell you the limiter is
responding to signal peaks.
Caution! If the Limit LED stays red while the unit is up and running, it
is being overloaded. Turn down the signal level! If you are not routing a
signal in and the Limit LED stays red, the system has detected a fault.

• ELEMENTS setup:
E 110 Sub A/AS + L SUB 1500 A -> Phase = 180°
(X-Over Bass = 100 Hz)
E 210 Sub AS + L SUB 1800 A -> Phase = 180° (X-Over Bass = 100 Hz)
