Controls and Functions
1. MASTER LEVEL -
This control adjusts the overall signal level at the input of the
D1800's power amplifier. This control does not affect the signal sent to the Full
Range and High Pass Outputs.
2. PHASE Switch -
Use this switch to set the polarity of the amplified signal. In the
out (NORMAL) setting, there is no change to the signal. When the switch is pressed
to the in (INVERT) setting, the signal's polarity is changed by 180°. The setting of
the Polarity switch has no effect on the signal sent to the Full Range and High Pass
Outputs.
3. PEAK Indicator -
This red LED lights when the amp is near the clipping point.
If the Peak indicator lights frequently, turn down the Level control on the Auro
subwoofer or turn down the signal at the source, until the indicator does not light
anymore, or lights only occasionally with signal peaks.
4. SIGNAL Indicator -
The green SIGNAL LED lights whenever signal is present at the
D1800's inputs.
5. POWER Indicator -
This LED lights RED when the amp is active.
6. INPUTS (L and R) -
The D1800 features electronically balanced female XLR stereo
line inputs. The left (L) and right (R) input signals are mixed together before they
are routed to the internal amplifier.
7. HIGH PASS Outputs (L and R) -
Electronically balanced male XLR stereo line
outputs, for sending the signal present at the INPUTS to your full range main
loudspeakers. The signal is first processed by the internal 12dB per octave, 126Hz
Linkwisz-Riley active crossover before reaching the outputs.
