  1. Monaural Input Channel An in-depth look at a single channel on the Mixing Console in the Main Stage

  2. 1

  3. 1. +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.

  4. 2

  5. 2. Gain • This 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 Noise • Gain is high + Fader is low = Incr. Chance of Distortion • Gain just right + Fader just right = Purrrrrrrfect.

  6. 3

  7. 3. 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.

  8. 4

  9. 4. Phase Switch • This reverses the phase of the input signal. • Used to prevent sound waves from going out of phase and cancelling each other out.

  10. 5

  11. 5. High pass filter • The High pass filter attenuates any frequency below 80 Hz by an 18 dB/oct curve.

  12. 6

  13. 6. Equalizer (EQ) Controls • This is a four band equalizer. • Meaning you can adjust four different frequencies on one channel.

  14. Shelf vs. Peak Top Shelf – Boosts or Reduces all frequencies above the center frequency. Peak– Boosts or Reduces center frequency as well as some frequencies above and below. Bottom Shelf – Boosts or Reduces all frequencies below the center frequency.

  15. 7

  16. 7. EQ Switch • Turns the EQ on and off. • When off the signal bypasses the EQ pots.

  17. 8

  18. 8. 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.

  19. 9

  20. 9. AUX Pre Switches • If 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.

  21. 10

  22. 10. Pan • Adjusts the pan or balance of the signal. • Can do 3 different things • When 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.

  23. 11

  24. 11. Channel(Bus) Assign Switches • These 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.

  25. 12

  26. 12. ON/EDIT • Turns 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.

  27. 13

  28. 13. PEAK/NOM/SIGNAL • These 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.

  29. 14

  30. 14. Channel Fader • This 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.

  31. 15

  32. 15. 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.
