11. +48V (phantom power)This switches the phantom power on/off.Phantom power provides 48 volts to the corresponding channel.This is most often used for condenser mics.2
2. GainThis adjust the input sensitivity.The higher the gain, the larger the input signal will be. Think of the Goldilocks Rule for gain.Gain is low + Fader is high = Increased NoiseGain is high + Fader is low = Incr. Chance of DistortionGain just right + Fader just right = Purrrrrrrfect.33. 26 dB Pad (attenuator)This attenuates, or reduces, the input signal by 26 dB.Attenuators are use to decrease the power of an input signal without distorting the waveform. Think of it as the opposite of an amplifier.44. Phase SwitchThis reverses the phase of the input signal.Used to prevent sound waves from going out of phase and cancelling each other out.
55. High pass filterThe High pass filter attenuates any frequency below 80 Hz by an 18 dB/oct curve.66. Equalizer (EQ) ControlsThis is a four band equalizer.Meaning you can adjust four different frequencies on one channel.

Shelf vs. Peak
Top Shelf Boosts or Reduces all frequencies above the center frequency.Bottom Shelf Boosts or Reduces all frequencies below the center frequency.Peak Boosts or Reduces center frequency as well as some frequencies above and below.77. EQ SwitchTurns the EQ on and off.When off the signal bypasses the EQ pots.88. AUX Controls (1-14)The adjust the level at which the signal of the monaural input channel is set to AUX buses 1 to 14.Provide additional or auxiliary mixes.We mainly use them for Monitors.99. AUX Pre SwitchesIf theses switches are on, the post-EQ signal will be sent to the AUX buses. If they are turned off the post-Fader signal will be sent.In other words when the pre button is pressed, the pre-fader signal is sent to the AUX bus. This means that the fader can be turned down and you still get signal to the AUX bus.1010. PanAdjusts the pan or balance of the signal.Can do 3 different thingsWhen the ST switch is on: Pan adjusts the signal from right to left in the STEREO L/R bus.When the LCR switch is on: Pan adjusts the signal between the STEREO L/R bus and the MONO bus.When a 1-2/3-4/etc. switch is on: Pan will send signal to either odd (Left) or even (right) group buses.1111. Channel(Bus) Assign SwitchesThese switches assign the post-fader, post-pan signal to the desired bus.1-2/3-4/etc. When pressed signal will be sent to the corresponding GROUP bus.ST When pressed signal will be sent to the STEREO bus. (Our Main Faders)MONO When pressed, signal will be sent to the MONO bus.LCR When pressed, signal will be sent to both the STEREO and MONO buses. 1212. ON/EDITTurns the channel On and Off.When On, the signal is sent to all selected buses.When Off, no signal leaves the mixer, however the input can still be monitored with the PFL button. 1313. PEAK/NOM/SIGNALThese are three indicators that all you to monitor the pre-fader signal.Peak Lights up Red when the signal exceeds the nominal level of 17 dB. (Peaking Causes Distortion)Nom Lights up Yellow when the signal reaches the nominal level of 0 dB.Signal Lights up Green when the signal reaches the nominal level of -13 dB.1414. Channel FaderThis adjusts the output level, or amplitude or the channel signal. It affects the level of signal sent to the GROUP, STEREO, MONO/C, and AUX (if pre is not selected) buses.
1515. PFL (Pre-Fader Listen)When the switch is on, the pre-fader signal will be sent to the MONITOR INPUT PFL bus, and can be monitored from the MONITOR OUT and PHONES jacks.
