VS12 BACK PANEL
1
INPUTS 1 AND 2
These combo inputs are designed for either TRS or XLR balanced plugs at
line level, either from a mixer or another speaker. The source can be either
mono or stereo.
2
OUTPUTS 1 AND 2
These outputs feed through the signal(s) received from the input(s). If
the crossover is not set to Full-Range Output, the output signal(s) will
be altered by the crossover, which removes audio below the selected
frequency, to allow your speakers that are fed by the sub to focus all their
energy and fidelity on reproducing signals above the selected frequency.
3
POLARITY
This switch lets you reverse the polarity on the power amp when needed
to match the polarity of speakers that may operate with opposite polarity
to the VS12, or to account for a phase difference due to the physical
distance between the sub and the full range speakers it is operating with.
Once you get your VS12 operating as part of your full setup with your
full-range speakers, try both settings of this switch, and leave the switch on
the setting that provides the most low frequency impact.
4
LEVEL SWITCH
Set this switch to match the output level of your source:
- Use +4 when your source operates at +4dBu
- Use -10 when your source operates at -10dBV
If you notice that the rear panel LIMIT LED or front panel LED is easily or
frequently lit red, even when you have the LEVEL knob turned to a low
setting, set this switch to +4 rather than -10.
5
VOLUME KNOB
Sets volume of internal speaker.
6
CHARGE JACK
Provides power for mobile devices.
7
TIME ALIGNING DELAY
After you’ve set up your system including the VS12 subwoofer and
your full-range speakers, and are playing audio through the system
to evaluate the low frequency response, set the POLARITY switch for
maximum low frequency impact, and then turn this knob until maximum
sub bass is heard.
8
CROSSOVER
This knob controls the high precision DSP crossover. Select a value
between 70 and 150Hz to have the audio below the selected frequency
filtered out of the output signals. Select Full-Range Output to disable the
crossover, and output the same full range audio received at the outputs.
The audio sent to the internal power amp and speaker will also be filtered,
so the subwoofer’s speaker produces only audio below the crossover
frequency. When Full-Range Output is chosen, the subwoofer’s speaker
limits its top frequency range to 150Hz.
9
LEDS
- POWER: this LED and front LED will light white when power is on.
- SIGNAL: this LED lights green when audio input is detected.
- LIMIT: this LED and front LED light red when limiter is activated due
to very high level audio input, indicating the VOLUME knob should be
turned down to avoid distorted sound. If the LIMIT LED comes on when
the VOLUME knob is already at a low level, try setting the LEVEL switch
to +4.

IEC POWER INPUT
Plug in the IEC AC power cable here.
11
VOLTAGE SELECTOR
Configures VS12 for your territory’s voltage. 100-120V is the standard in
the USA.
12
FUSE CARRIER
If the speaker will not power on and you suspect its fuse may have blown,
turn off the power switch, and open the fuse compartment using a small
flat blade screwdriver. If metal strip in fuse is broken, replace with T6.3
AL 250V fuse for 100-120 volt operation, or T3.15 AL 250V for 220-240
volt operation.
13
POWER SWITCH
Turns the VARI subwoofer on or off.
