MK Sound LFE-4 - Manual (Page 8)

6. CONNECTING FOR STEREO
1. Connect the left and right outputs of your mixer to the left and right input channels of the LFE-4.
2. Connect the left and right outputs of LFE-4 to the inputs of your power amplifiers or directly to your
powered loudspeakers.
3. Connect one of the subwoofer outputs of the LFE-4 to the XLR input of your subwoofer. Set your M&K
Professional subwoofer as follows: set the filter switch for THX, set the phase switch to plus and set the
gain switch to the THX position.
4. If you are using passive speakers with external amplifiers, connect your speaker system to the
power amplifiers.
5. Locate the external power supply for the LFE-4 and plug it into the 4 pin power connector on the back of
the LFE-4. Secure it in place by turning the outer ring clockwise. Plug the external power supply into a
power outlet. The front panel LED will glow red when power is applied.
(NOTE: If you are working in mono or stereo, do not connect any cables to the low frequency effects (LFE)
inputs as these formats do not use a discrete low frequency effects track.)
