1 MAIN SIGNAL XLR INPUT (BAL/UNBAL). The system accept female XLR input connectors
and line-level signals from a mixing console or other signal source.
2 SIGNAL LINK XLR OUTPUT. The output XLR male connector provides a loop trough for
speakers daisy chaining.
3 XOVER SIGNAL OUTPUT. The output XLR male connector provides a crossover high passed
signal (24 dB/octave) for satellites speakers.
INPUT SENSITIVITY. Controls the overall signal level at the input to the power amplifier. The
4
control ranges from + ∞ dBu (maximum attenuation) to the –2 dBu – MAX sensitivity (maxi-
mum input gain). The centre detent is +4 dBu (nominal level required to drive the amplifier at
maximum power).
5 DEEP - PUNCH. This switch provides a DEEP equalisation (flat response down to 30 Hz) or
a PUNCH equalisation with a boosted equalisation at 70 Hz.
6 XOVER 90/120 HZ. Provides 24 dB/octave low-pass filtering at 90 Hz if released, at 120
Hz if pressed. The same crossover frequency in high-pass is available from XOVER OUTPUT XLR.
7 TIME DELAY ENCODER. This encoder provides a time delay setting expressed in meters.
POWER INDICATOR. Power on indicator. When the power cord is connected and the power
8
switch is turned on this indicator lights green.
SIGNAL INDICATOR. The signal indicator lights green if there is signal present on the main
9
XLR input.
10 LIMITER INDICATOR. The amplifier has a built in compressor/limiter circuit to prevent clip-
ping of the amplifiers or overdriving the transducers.
When the compressor is active the led is blinking yellow. When the soft clipping circuit is active
the LED blinks orange. It is okay if the limit LED blinks occasionally. If the LED blinks frequently
or lights continuously, turn down the signal level. The amplifier has a built in RMS limiter. If the
RMS limiter is active the LED lights red. The RMS limiter has the purpose to prevent damages the
transducers. The speaker shall never be used with the limit indicator red, continuously. Continu-
ous operation with the RMS protection active can cause damages to the speaker.
11 PHASE SWITCH. This switch reverse the phase of the output signal.
