Setup
Level
Adjust the level of audio output from the Sub. Begin with the Level Control set to a low setting and increase
the level until the Signal/Clip Indicator illuminates green. The Level Control does not affect the Line Outputs.
The 12 o'clock position is recommended when in use with an L1 Pro32. If using two Subs with a single L1 Pro, it
is recommended that the Level Control is set to the same position on both Subs.
Line Input EQ
Change the EQ of both Line Inputs by pressing the Line Input EQ button until the
corresponding LED for your desired EQ illuminates white. Use L1 to apply an input
EQ optimized for L1 Pro products; use LPF to apply a low-pass filter to the inputs.
When a Sub is connected to an L1 Pro32 with a SubMatch cable, the Line Input EQ
will be fixed to L1.
Line Output EQ
Change the EQ of both Line Outputs by pressing the Line Output EQ button
until the corresponding LED for your desired EQ illuminates white. Use FULL for
full frequency or HPF to apply a high-pass filter to the outputs.
Note: If using the Sub with an S1 Pro, press and hold the Line Output EQ button
for four seconds to enable an EQ specifically optimized for use with an S1 Pro.
The HPF LED will illuminate green. To deactivate the S1 Pro EQ, press and hold for
four seconds.

WARNING: Do not place the equipment in an unstable location. The equipment could become unstable
leading to a hazardous condition, which could result in injury.
CAUTION: Do not stack more than two Subs together. Only stack two Subs of the same model.
For horizontal configurations, adjust the logo by rotating it.
For stacked configurations, the Sub includes four interlocking feet that will attach to another
Sub of the same model. When stacking Subs horizontally, always make sure the feet lock
together before connecting power and sources.
