12. Phase Switch - Depending on the location of the subwoofer, its sound may arrive at
your ears out of phase with the sound from the full-range monitors. Use this switch
to change the phase of the sound coming from the subwoofer by 180 degrees. In
most cases the correct phase coincides with the louder output.
13. OFF/AUTO/ON Switch - Use this switch to select your preferred method of
operation. With the switch set to the OFF position, the subwoofer will be off and any
input signal will be passed through to the outputs to drive other speakers. With the
switch set to the AUTO position, the subwoofer will automatically shut down when no
signal is present and will turn on when a signal is detected. With the switch set to the
ON position, the subwoofer is always on, regardless of whether or not it is receiving
a signal.
14. Sub Bypass (Foot Switch) - Connect a foot switch (not included) to this 1/4" TS
jack. When the foot switch is engaged, the subwoofer and crossover are bypassed,
allowing the original, full-range signal to be sent to the outputs. This allows you to
compare your mixes with and without the subwoofer handling the lower frequencies.
15. Power Switch - This switch turns your subwoofer on and off.
16. AC Jack - This AC input accepts a power cable with a grounded IEC 60320 C14
plug on one end and a grounded NEMA 5-15 plug on the other. The appropriate AC
cable is supplied with the unit. If you need a replacement or want a longer cord, use
a cord with the exact same connectors and at least the same wire gauge.
17. Fuse Holder - A fuse is used to protect the amplifier and crossover circuit from
excessive current. The fuse used in a T4AL 250V fuse. Replace the fuse only with
the exact same type.
