1 . Sub bass high cut
This control can be used to change the bass
crossover frequency from 80 Hz to 200 Hz . For
deep sub bass response select 80 – 100Hz .
2 . Limiter control
The threshold level where system limiting begins
to occur is adjustable and can be set to protect
low power handling speakers or as a max SPL
adjustment when noise level needs to be limited for
environmental reasons .
3 . Status indicators
There are indicatiors for signal presence, clip/
compression and power . The QM 1000P soft knee
limiting will prevent severe amplifier clipping, but
when a mixer signal source is driven into severe
distortion, some audible amplifier clipping may
result .
4 . Satellite volume level controls
L + R input and sub bass volume controls drive the
satellite and bass amplifiers outputs .
5 . Sub Volume
Volume control for the internal 950 watt (4Ω) mono
sub bass amplifier . When used in conjunction with
the Master L&R input, a balance between the low
frequencies of the sub bass and the mid high output
from the satellite speakers can be optimised for the
venue and the music source .
6 . Power on/off
Operational Note:
For tuning and adjusting the bass sound, set high
cut for adjustment of the upper bass cross-over
frequency fowr the Sub bass amplifier set to below
100 Hz for low bass, above 125 for a higher range of
bass frequencies .
Subwoofer volume:
To control sub bass volume level . By increasing
input volume and adjusting subwoofer volume,
a balance the satellite speakers and the sub
bass can be achieved .
