M-AUDIO Fineline - Manual (Page 12)

If you want to use FineLine as a stereo microphone mixer you must have
1/4” phone jacks plugged into both the Mic1,2 and Mic3,4 Output Jacks.
This is because the Mic1,2 Output Jack is “switched,” and when a plug is
inserted into it stereo operation is turned on (see Block Diagram in the
back). If you also want a stereo microphone, mix the rear panel Mono Mic
Switch must be Off. If you don’t need to add effects to your microphones
and you want a stereo microphone mix you need to run a cable from the
Mic1,2 Output to any of the Left line Inputs, and from the Mic3,4 Output
to any of the Right line Inputs.
If you want a mono mix of the microphones and you don’t need to add
effects to the mix, you can turn the rear panel Mono Mic Switch On. If this
switch is On a mono mix of the microphones will be routed directly to the
main Left and Right Outputs, as well as appearing at the Mic3,4 Output.
If you wish to add effects to your microphones, connect both Mic Outputs
(for stereo) or the Mic 3,4 Output (for mono) to the input(s) of your effects
unit. Plug the output(s) of your effects unit into one (for mono) or two (for
stereo) free FineLine line level Inputs. You can now control the amount of
effects you add to the microphones by using the mix control on the front
of the effects unit.
Mic levels can be controlled by using the Mic Level pots on the front of
FineLine. The Mic Clipping LED will light when any Mic is too hot. With
this in mind, first turn all Mic Levels down. Next, test each microphone
individually by turning the its corresponding Mic Level up until you see
the Clipping LED light, and then back the Mic Level off slightly. Do this
with all of your microphones. If the Clipping LED still lights back all of
the Mic Levels off slightly.
Setting-up the Outputs
If you are using FineLine in live performance you will now connect one
Output (for mono) or both Outputs (for stereo) to the input(s) of a power
amplifier. If you are using FineLine in a studio application you will prob-
ably plug one Output (for mono) or both Outputs (for stereo) into one (for
mono) or two (for stereo) inputs on your mixing board.
If you are using FineLine as a mono mixer (i.e. if the front panel
Mono/Stereo Switch is set to Mono), the mono mix output signal will go
