3.1 CONTROL PANEL - AS 101S -
LEVEL CH1/CH2 (1)
- High-pass output level control,
which determines the amount of signal sent to the
satellites. Turn the knob completely clockwise for
unitary gain.
PHASE (2)
- Phase inversion 0°- 180°. In some
installations, the subwoofer may be out of phase with
the satellites. This switch allows you to reverse the
phase of the subwoofer and align the system.
CLIP (3)
- Clip indicator LED. This indicator
allows you to visually monitor the volume level of
the loudspeaker. LED OFF: compressor/limiter is not
engaged. LED ON for a few moments: brief engaging of
the compressor/limiter, inaudible to the ears—you are
approaching maximum power output, and the speakers
are being protected. LED ON: the audio signal is too
high, and you should lower the output level of your
audio source, or turn the level knob (5)
counterclockwise.
LEVEL (4)
- This control determines the amount of
signal that passes through the input stage of the
subwoofer. Turning it completely clockwise will
result in maximum gain. The appropriate subwoofer
level can vary significantly depending on the
acoustics of the venue and the genre of music you’re
playing. Carefully set the satellites’ level first
and then add bass frequencies (subwoofer level) as needed.
ON (5)
- Power status indicator LED. Illuminates when the power switch is ON and the power
cord is plugged into a power source.
HIGH-PASS OUT CH1 & CH2 (6)
- Line out for connecting to OAS system satellites. The
crossover frequencies for the AS Series satellites are sent from these outputs. The
crossover frequency is set at 120 Hz.
INPUT CH1 & CH2 (7)
- Line input jacks for connecting stereo audio sources. The XLR 3-pole
female jacks are electronically balanced (hot pole #2). You can use unbalanced sources if
your cables have pole 3 jumpered with pole 1.
INPUT CH1 & CH2 GROUND LIFT (8)
- A switch that disconnects the ground of the input audio
signal from the electric ground of the power amp module. This switch may be needed for the
cancellation of hum due to ground loops with other apparatuses. If flipping this switch
does not solve the problem, identify the apparatus upstream that is creating the problem
and take whatever measures are necessary to eliminate
the hum.
LINK CH1 & CH2 (9)
- Line out to connect more subwoofers downstream from the principal
system. This 3-pole male XLR jack receives a female XLR plug (7) and sends out a passive
signal.
LINK CH1 & CH2 GROUND LIFT (10)
- A switch that disconnects the ground of the input audio
