Miller & Kreisel Sound LP-1S Operating Instructions

The M&K LP-1S gives your system full bass biamplification with your M&K Powered Subwoofer. The
LP-1S uses purely passive circuitry, introducing virtually no noise or distortion. There is no low pass filter
in the LP-1S. It feeds a full range signal to your Subwoofer. The filter circuit in your M&K Powered Subwoofer
matches the high-pass of the LP-1S and requires no additional circuitry. The LP-1S is not designed for use
with the original Volkswoofer (cube style cabinet), the Volkswoofer-A, or the Volkswoofer-III.
The LP-1S can be located almost anywhere it fits conveniently around your components. It is sensitive to
hum, however, so it cannot be placed next to a power transformer. If the LP-1S sits too close to such a
transformer (like in your power amp or receiver), it will pick up hum. If you hear hum through your system
when using the LP-1S, try relocating the LP-1S.
IMPORTANT NOTE:
your main power amplifier. This cable should be as short as possible. The capacitance and length of the
cable to the Subwoofer are not critical.
Now, look at the LP-1S. You will find four pairs of jacks. From left to right, they are: BASS OUTPUT;
TREBLE OUTPUT; INPUT; and SPECIAL. The SPECIAL jacks duplicate the INPUT jacks and are not
used.
1. Run a stereo interconnect cable from the MAIN output of your preamplifier (or PREAMP OUTPUT
jacks on an integrated amplifier or receiver) to the INPUT jacks on the LP-1S. Run one side from the preamp
Left MAIN output to the INPUT jack labelled "L". Run the other side from the preamp Right MAIN output
to the INPUT jack labelled "R".
low capacitance
2. Run a
amplifier's INPUT (or integrated amp or receiver's MAIN or POWER AMP IN jacks). Run one side between
the jack labelled "L" and the power amp's Left INPUT. Run the other side between the jack labelled "R" and
the power amp's Right INPUT.
3. Run a stereo interconnect cable from the BASS OUTPUT jacks on the LP-1S to your Subwoofer's
FROM PREAMP jacks. The jack labelled "L" feeds the Left INPUT jack and the jack labelled "R" feeds the
right FROM PREAMP jack.
If you have two Subwoofers, run a mono cable from the BASS OUTPUT jack labelled "L" on the LP-1S to
the Left Subwoofer's Left/Mono INPUT jack. Run another mono cable from the BASS OUTPUT jack labelled
"R" on the LP-1S to the Right Subwoofer's Left/Mono INPUT jack. You only need to use the Left/Mono
INPUT jack on each Subwoofer.
Your wiring is now complete.
