LEVEL SUB (12) - 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.
CLIP (13) - 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.
ON (14) - Power status indicator LED. Illuminates when the power switch is ON and the power
cord is plugged into a power source.
POWER JACK (15) - Power jack for connecting the unit to a power source. Fuse housing.
ON/OFF SWITCH (16) - On/off power switch. It's good practice to power on the subwoofer only
after you've plugged in the power cord and signal cables, and turned on all audio sources
(mixer, effect units etc). Turn the switch off BEFORE unplugging the cabinet and before
turning off any connected equipment.

3.3 CONTROL PANEL - AS 211S
INPUT RIGHT & LEFT/MONO (1-3) - 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.
LINK RIGHT & LEFT/MONO (2-4) - Line out to connect more
subwoofers downstream from the principal system. This
3-pole male XLR jack receives a female XLR plug and sends
out a passive signal.
INPUTS & LINKS GROUND LIFT (5-6-7-8) - A switch that
disconnects the ground of the input audio signal from the
electrical ground of the power amp module. This switch may
be needed for the cancellation of hum due to ground loops
with other apparatuses.
If the audio signal is already disturbed when it arrives to
the loudspeaker, this switch will not solve the problem.
Identify the upstream component that is creating the
problem, and take whatever measures are necessary to
eliminate the hum.
PC CONTROL - INPUT & LINK (9-10) - OPTIONAL (SOLD
SEPARATELY) - RJ45 connector links your cabinet to your
computer through the MARKAUDIO PC BOX (sold separately).
Thanks to the Markaudio software you can tune the cabinets
to any venue, with both 21-band graphic and parametric EQ,
modifiable limiter and crossover settings, and more!
