M-AUDIO Fineline - Manual (Page 6)

Turning a send pot all the way down will prevent any of that signal from
appearing at the Send mix Output, while turning it all the way up will
send it out the Send mix Output with 6 dB of gain.
Mono Mic Switch & MIC 1,2/3,4 Outputs
With the Mono Mic switch located on the back of FineLine in the Off posi-
tion, the four XLR microphone inputs and the two Mic outputs are inde-
pendent of the rest of the FineLine mixer.
When the MIC 3,4 Output is used and nothing plugged into the MIC 1,2
Output, all four microphones are mixed monaurally according to the lev-
els set by the corresponding four front panel MIC pots. This mixed mono
signal appears at the MIC 3,4 Output.
When a cable is plugged into the MIC 1,2 Output, microphones 1 and 2
will only appear at the MIC 1,2 Output, while microphones 3 and 4 will
only appear at the MIC 3,4 Output.
When the Mono Mic switch is turned On, the signal at the MIC 3,4 Output
is additionally routed to both the Left and Right main Outputs.
Signal levels of all four microphones are summed together and monitored
by the two Mic indicator LEDs which show signal presence and clipping
level.
Power Indicator
FineLine runs on 9 to 12 volts AC. Whenever FineLine is plugged in the
Power LED should remain lit. If the Power LED goes off check to make
sure your wall supply is properly plugged in and powered.
