(13) FUSE HOLDER
Under normal operation the fuses should not blow. A blown fuse usually indicates an overload or fault
condition. To change the fuse, remove the power cord, pry off the fuse block with a small flathead
screwdriver and change the blown fuses. Refer to the Specifications section for fuse current ratings.
NOTE: If the fuses blow immediately upon power up, this indicates a fault condition and the monitor
should be returned to KRK for repair.

(14) FOOTSWITCH

The footswitch connection is a bypass feature which allows the user to defeat the sub and provide full
range audio to your recording monitor in instances where the Line Outs are being utilized. This feature is
of great benefit in that the high-pass filter is bypassed allowing full bandwidth to run to the monitors
while muting the subwoofer. This allows the user to evaluate the impact of the subwoofer on the mix. The
KRK12sHO includes one KRK KFS-1 latching footswitch with LED indicator. For the LED indicator to be
utilized a ¼" TRS cable is required between the footswitch and the KRK12sHO. A ¼" TS cable can be used
with the KRK KFS-1 footswitch bypass feature with the exception that the LED indicator will not be
required.

Connecting Your System

IMPORTANT: Before starting up the subwoofer, be sure all connections are made, all fader
and controls should be set at their minimum levels, and all other equipment should be
powered prior to powering up your KRK12sHO subwoofer. If you are connecting the sub's Line
Outs to your monitors, turn monitor power on after the subwoofer.
KRK subwoofers include a built-in crossover and amplifier, so you only need the appropriate hook up
cables to integrate it into your existing monitor system. First, you'll need to connect a pair of cables from
the stereo monitor outputs of your console (or audio hardware device) to the left and right XLR or ¼"
input jacks on the subwoofer. Next, if you are using the internal 80 Hz high-pass filter built into the
subwoofer for the existing full-range monitors, hook the XLR output jacks on the subwoofer to the line-
level inputs of your full range monitors.
A more advance system is required if the preference is to not use the internal 80Hz high-pass filter. Such
advance systems would require the use of an external crossover. It is recommended to use an external
crossover that features a subwoofer output connection. Consult the external crossover user manual to
learn how to setup and connect the full range monitors and a subwoofer.
