REAR/ contRoLS
(LDDDQ12 pIctuRED)
:
1
ANALOG INPUT
Balanced XLR line input (23 dBu max.).
2
INPUT LINK
Balanced XLR line output
3
SUB OUT
Balanced XLR subwoofer line output
4
GAIN DB
Input sensitivity control with respect to the volume
of the amplifier module. If the maximum input
level (23dBu) is exceeded, this is indicated by
collective flashing of LEDs 7-10. In this case,
reduce the level of the signal source to avoid
negative effects on the sound.
5
LOW CUT / SUB OUT
Enabled switch activates both the high pass filter
for DDQ10/12 (100 Hz, 18 dB/oct. Butterworth)
and the low pass filter (100 Hz, 18 dB/oct.
Butterworth) for the SUB OUT. If the switch is not
enabled, the sub output signal is not affected by
any filter.
6
GROUND LIFT
Can eliminate ground loop hum if devices with
varying ground potentials are connected.
7
OPERATE LED
Lights up once the speaker system is switched on
and properly connected to the power mains.
8
SIGNAL LED
Lights up when an audio signal is present at the
line input (> -30dBu).
9
PEAK LIMIT LED
Lights up if the speaker is operating in the
clipping range. Brief flashing is not a cause for
concern, since the internal audio limiter compen-
sates for over-modulation. Permanent illumination
should be avoided by reducing the input level.
