DJs. This manual is intended to inform you of the many features of your new KRK subwoofer and its operation. We encourage you to take a few minutes to familiarize yourself with the information in this manual.
After unpacking your subwoofer, carefully inspect it for exterior damage and immediately report any physical damage during transit to your shipping carrier. Save the shipping boxes and all packaging materials in case the unit needs to be returned to your local dealer or KRK Systems, LLC.

Using the Ground Lift Engaging the ground lift switch can sometimes reduce ground loop noise in your system. By providing an AC mains ground on the KRK10s and proper installation in a 'quiet studio' environment, the system is happily quiet.
Hooking Up Your Subwoofer: Stereo Systems 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, 1/4”...

Subwoofer Hook Up with Passive Monitors If you are using passive (non-powered) monitors that require an external amplifier, connect the two outputs of the subwoofer to the inputs of the stereo monitor amplifier. Typically this would also be a XLR connector, but if need be, you can use the other connections providing the amplifier will accept them at the amp input.
There are some basic steps necessary to ensure you have a subwoofer operating in top form: 1) a room correction system such as KRK’s ERGO and/or room treatment; 2) proper placement of the sub within the room; and 3) proper electrical settings.

Using the Bypass Feature Your KRK subwoofer is equipped with a by pass feature which allows you to defeat the sub and provide full range audio to your recording monitors in instances where your Line Outs are being utilized.
Hooking Up Your Subwoofer: 5.1 Surround This is a bit more involved than a stereo hook up since there are now six speakers involved— as well as something called Bass Management (see the Bass Management Theory section). Notice from Figure 3 that for professional use a separate 6-channel level control box is required between the mix-down deck and the monitor speakers.

Beyond Stereo to 5.1 Surround When using a subwoofer for the LFE (Low Frequency Effects) channel in a 5.1 surround monitoring system, rotate the low pass filter all the way to the right to the 130Hz position. Note that the LFE channel is set with an additional 10dB of monitoring gain. To set this level, we recommend using 2-octave wide, band-passed, pink noise from 20 to 80Hz for the LFE channel and 500 to 2,000Hz for the near-field speakers.
Bass Management Theory Bass management is a method for extending the bass response of small, near-field speakers used in 5.1 surround sound systems (familiarly called home-theatre systems). This is done by routing frequencies below a cutoff point to a separate subwoofer (sometimes called “bass redirection”...
The subwoofer grill can be removed and the grill’s rubber gasket can be reinserted to show off your KRK10s woofer. However, if you place your subwoofer in proximity to your feet we highly recommend leaving the grill on to protect the speaker! To Remove the grill and replace the grill’s rubber gasket, follow these directions:...
