If you hear a thump through your MK Sound Subwoofer every time you turn the system on while using the "FROM PREAMP" input terminals, switch to the speaker wire "FROM AMPLIFIER" input terminals. This thump is likely generated by the preamp, receiver, or surround sound processor.
What to do if MK Sound MX-200 cuts out at high volume?
If your MK Sound Subwoofer cuts out or becomes intermittent after prolonged operation at high volume, unplug the unit and let it sit for at least half an hour. After that time, plug it back in. It should operate normally. This may occur because, after hours of continuous operation at extremely high volume levels, a protection circuit may kill the power to the Subwoofer.
Why is my MK Sound Subwoofer volume low when using amplifier terminals?
If your MK Sound Subwoofer has very little output when using the "FROM AMPLIFIER" terminals, make sure that the input cables are in phase. Reverse the (+) and the ( — ) connections for ONE CHANNEL ONLY at the "FROM AMPLIFIER" terminals. If the problem remains, put the cables back as they were.
How to fix MK Sound MX-200 with no output?
If your MK Sound Subwoofer has no output, ensure it is plugged into an AC outlet. Check the "BASS LEVEL" control and make sure it is set above the "MIN" position, rotating it clockwise if needed. Examine the red LED on the Subwoofer's back panel. If it's unlit, check the AC fuse next to the LED (unplug the Subwoofer before changing the fuse) and replace the fuse if the element inside is broken. If the red LED is lit, turn the "BASS LEVEL" control to "MIN", plug a standard RCA cable into the "FROM PREAMP" jacks, and lightly touch the plug at the free end of the cable while slowly turning the "BASS LEVEL" control clockwise. If you hear noise from the Subwoofer when you touch the cable, the Subwoofer is functioning, and you should look elsewhere in your system for the problem. Also, make sure...
Why does my MK Sound Subwoofer hum?
A hum or buzz in your MK Sound Subwoofer can often be due to the Subwoofer reproducing a 60 Hz hum frequency, which originates elsewhere in your system. To address this, avoid running speaker wires and RCA interconnect cables near AC cords and component power supplies. Reroute your cables if necessary. To identify the source, remove all input cables to the Subwoofer, but leave it plugged into the AC outlet and carefully turn the "BASS LEVEL" control up towards the "MAX" position. If you hear hum coming from the Subwoofer's speaker driver, the Subwoofer is the source of the hum. If you hear no hum or less hum, the problem is probably coming from another component. Hum can also be caused by AC ground loops. If the Subwoofer is plugged into a separate AC outlet, try plugging it into the same ...
