Subwoofer Hook-Up - MK Sound MX350 MKII Operation Manual

No matter where you place your 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. Please observe the following:
1. Leave adequate clearance around the subwoofer's heatsink. Do not cover it with
drapes or close it up in an unventilated cabinet.
2. Do not place the subwoofer near baseboard heaters or forced air heating outlets.
3. Do not use your subwoofer outdoors or in an overly humid environment.
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. If your receiver or processor has a line-level
subwoofer output (sometimes labeled "Sub", "Sub Out", "SW" or "LFE") with XLR or phono
connectors, use it. This is the preferred connection for your MK Sound subwoofer.
NOTE: You cannot use the "Tape Out" connectors on the rear of your
receiver/processor to connect to the line input connectors of your subwoofer,
because these outputs have a fixed output level that does not change when you
adjust the system volume control.
WIRING YOUR SUBWOOFER USING THE LINE-LEVEL INPUTS
The line-level XLR or phono inputs on the back panel of your subwoofer allow you to directly
connect your subwoofer to corresponding preamp-level outputs on components such as surround
sound receivers and processors that have pre-amp outputs.
Simply run a shielded interconnect cable with male phono plugs at each end or a balanced
interconnect cable with a female XLR plug on one end and a male XLR plug on the other, from
the pre-amp output of your receiver or processor to your subwoofer. If your subwoofer has left
and right inputs, it is not necessary to connect both. One cable connected to the left input is
sufficient.
This will give you better quality performance from your subwoofer than using the speaker inputs,
because the pre-amp output bypasses the amplifier stage of your receiver or processor.
