BEFORE plugging it into the AC wall socket. 4. WHERE TO PLACE YOUR SUBWOOFER MK Sound subwoofers perform well in most room locations. With a properly tuned speaker system, you should hear deep bass coming from the front of your system as if your satellites and subwoofer were one big system rather than separate speakers.
Some people believe that we can determine directionality from frequencies down to 60 Hz. In any case, MK Sound satellite speakers are tuned to crossover to an MK Sound subwoofer at 80 Hz. This is also the Dolby Laboratory and THX specification.
4. Do not plug the subwoofer into an AC outlet until all system wiring is complete. 5. SUBWOOFER HOOK-UP Some MK Sound subwoofers come with speaker wire connections as well as line-level phono (sometimes referred to as RCA) connectors. Some models are fitted with line-level phono and XLR connectors, but no speaker wire terminals.

FIGURE 1. CONNECTING TO A COMPONENTʼS SUBWOOFER OUTPUT FIGURE 2. CONNECTING TO A STEREO AMP OR PRE-AMP If your processor, receiver or amplifier has XLR-connectors, use these. If you don’t have a subwoofer output available, check to see if you have pre-amp outputs on your pre-amp, amp, receiver or processor.
USING SPEAKER WIRE CONNECTIONS Some MK Sound owners hook up their subwoofers by connecting them to their receiver or amplifier using speaker wires. To do this, you make the same kind of connections that you would use to connect your satellite (or main) speakers, except that both the left and right channels first go to the subwoofer.
If the system is not working properly, unplug the subwoofer and check all of your connections. If you still have no success, contact your MK Sound dealer. NOTE: Once you have achieved a rough subwoofer level setting, refer to the system set-up guide found later in this manual.
6. USE OF THE PHASE CONTROL Some MK Sound subwoofers feature a phase switch (0 or 180 degrees) and some feature a phase control (continuously variable from 0 to180 degrees). This control will help you to fine-tune the transition between sound sent to your main speakers and your subwoofer.
It provides a roll-off of 12 dB/octave up to 200 Hz where the filter shifts to 36 dB/octave. In most systems, including MK Sound systems, 80 Hz gives the best blend. The satellites, or main speakers, will reproduce frequencies from 80 Hz to 20 KHz and your subwoofer will reproduce frequencies from 80 Hz down to 20 Hz.
(“ON” or “Yes” in the set-up menu). 11. TROUBLESHOOTING Your MK Sound subwoofer amplifier provides high reliability and, in the rare event service is ever required, easy modular replacement of parts. This section of the manual will help you to solve or diagnose most problems that can occur with your subwoofer.

After that time, plug it back in. It should operate normally. If you find this happens frequently, contact your MK Sound dealer. If you are using the “FROM AMPLIFIER” speaker wire terminals and the subwoofer has very little output: 1.
12. IF YOU NEED SERVICE Contact your MK Sound dealer. Do not send your speaker to MK Sound directly without obtaining prior authorization. SYSTEM SET-UP GUIDE The 5 Most Important Items in System Set-up: 1. Find the best location for the subwoofer for maximum output and flattest response (possibly the corner closest to the listening position) 2.

Speaker Set-Up 1. Front Speaker Placement The left, right, and center speakers should be equidistant from the main listening position. Try to set up the speakers so that they are reasonably symmetrical to room surfaces. A tape measure may be very helpful. Subwoofer Placement One possible location for the subwoofer is the corner with the best structural strength.

A. High-Pass Filters: All Dolby Digital processor/receivers have built-in high-pass filters for the Left, Center, Right, Left Surround, and Right Surround channels. When using MK Sound speaker systems, turn these filters ON by using the SMALL setting. If you have a THX component, use the THX setting.

10. Check phase. Make sure that all five main channel speakers are wired in phase. The Video Essentials disc has tests for main speaker phase. 11. Make sure that the subwoofer and main speakers are in phase at the 80 Hz crossover point. Listen to something with a consistent bass line around 80 Hz while a partner switches the “Phase”...
