MK Sound MX-125 MK II - Manual (Page 8)

page 8 powered subwoofers
In the MX-300, MX-200, and MX-125 Mk II, a full-range signal (including deep bass) is fed to your
Satellites. To roll off (filter) the signal fed to the Satellite speakers for biamplification, you must:
1. Have a separate amp and preamp OR a receiver or integrated amp that allows you to
separate its amp and preamp stages.
2. Use a surround sound processor or receiver that has built-in high-pass filters and a subwoofer
output jack.
3. Add an M&K Electronic High-Pass Filter to your system. See Page 9 for more information.
WIRING WITH THE RCA JACK INPUTS
The "INPUT" RCA jacks on the 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.
Using these inputs gives you better bass quality than using the speaker inputs (it bypasses your
amp or receiver's amplifier stage). If you don't have a subwoofer output available, you must have
preamp outputs on your preamp, amp, or processor. If you have only one set of preamp outputs, use
a Y-connector to feed both the amplifier and the Subwoofer. In many cases, using a Y-connector may
slightly degrade the Satellite speakers' sound quality. Please feel free to experiment.
To connect the Subwoofer in this way, simply run a set of shielded RCA - RCA interconnect cables
from the output jacks on your component to the "FROM PREAMP" jacks on the Subwoofer's backplate.
See Figure 4.
FIGURE 4 - USING THE RCA JACK INPUTS
If you have one Preamp Output, connect both the Subwoofer and the Amplifier to it.
