All M&K powered subwoofers have exceptionally sharp (36 dB/octave) low-pass filters to remove the midbass and
midrange frequencies unwanted in a subwoofer. This makes your M&K subwoofer truly non-directional.
No matter where you put the subwoofer, you must allow room for ventilation of its heatsink and backplate. The subwoofer's
power amplifier is mounted on the backplate, and it generates heat.
1. Leave clearance around the subwoofer's heatsink. Do not cover it with drapes.
2. Do not place the subwoofer near baseboard heaters or forced air heating outlets.
3. Do not use the subwoofer outdoors or in a humid environment.
Do not plug the subwoofer into an AC outlet until all system wiring is complete.
4. SUBWOOFER HOOK-UP
There are two different ways to connect the Subwoofer to your system. One uses speaker wire, and the other uses inter-
connect cable with RCA-type jacks. If your receiver or processor has a SUBWOOFER OUTPUT RCA-type jack, use it. This is
the preferred connection for your M&K subwoofer. If your component does not, skip to "USING SPEAKER WIRE CONNEC-
TIONS" on the next page).
NOTE: Do not use "TAPE OUT" jacks to connect your subwoofer, because these jacks have a fixed output level that does
not change when you adjust the system volume control.
WIRING WITH THE RCA JACK INPUTS
The "INPUT" RCA jacks on the back panel of your Subwoofer allow you to directly connect the Subwoofer to preamp-level
components such as surround sound processors, preamplifiers, integrated amps and receivers with preamp outputs, Electronic
High-Pass filters, crossovers, etc. This will give you better bass quality than using the speaker inputs, because it bypasses your
amp or receiver's amplifier stage.
To connect the Subwoofer in this way, simply run one or a pair of shielded RCA - RCA interconnect cables from the
output jacks on your component to the "INPUT" jacks on the Subwoofer's backplate. See Figure 1. It is not necessary to use
both input jacks on the subwoofer.
USING THE BMC-MINI BASS MANAGEMENT CONTROLLER
The M&K BMC-MINI bass management controller can improve the performance of any system that allows for separation
of its preamp and power amp stages by filtering the bass signal fed to the main amplifier and Satellite speakers. This is not
necessary with home theater components that have built-in crossovers.
To use the BMC-MINI with an integrated amp or receiver, the amp or receiver MUST have back panel RCA jacks labelled
Preamp/Main Output AND Power Amp/Main Input. There may be a switch or jumper connections between them. Do not run
