Channel Screen - Advanced Mode
The MixPre II’s flexibility is enhanced by its ability to select various input types to its mixer channels. On the MixPre-3 II, channels
can be sourced from XLR mic/line input, 3.5 mm Aux line or mic input, or from USB channels. On the MixPre-6 II and MixPre-10 II,
channels can be sourced from XLR or TRS mic/line input, 3.5 mm Aux line or mic input, or from USB channels.
Access the channel’s input settings by pushing in the channel’s knob. There are three channel inputs on the MixPre-3 II, 6 channel
inputs on the MixPre-6 II, and 10 channel inputs on the MixPre-10 II.
Channels 5 and 6 on MixPre-6 II and 9 and 10 on the MixPre-10 II are controlled in the Inputs menu. Input source, solo, mute, arm,
gain, pan, low cut, and linking are all available in this menu.
Channels use a dual gain stage. Adjust the gain control in the Channel Screen and fader level with the knob. Limiters are present on
each channel and the LR mix bus and will ensure that your audio is safe from accidental clipping.
Solo
Lets you “solo” the selected channel in the headphone output. Solo mode can be set to “Individual” or “Multiple” in the HP menu.
When a channel is soloed, the LED ring will flash orange.
Mute
Provides quick access to muting an input.
Arm
Allows pre-fade recording of the channel to an individual track on the SD card.
Gain
Sets the sensitivity of the input. Generally, the Gain should be set so that the loudest parts of the audio signal just touch the red
segments of the meters. The control knobs on the front panel act as faders.
Pan
Lets you position the audio of the channel anywhere between Left and Right in the stereo image of the LR mix and Stereo Out.
Low Cut
Turn Low Cut filter on or off. Useful for reducing unwanted low frequency in the audio of the select channel. Frequency is adjustable
from 40, 80, 100, 120, or 160 Hz.
Input
Select one of the available Mic, Line, Aux (available when Aux In Mode is Mic or Line) or USB inputs as the channel source.
Phantom
Turn on 48 V phantom power when using a condenser microphone in the selected channel (available when Input is Mic)
Phase
Phase inversion (or polarity reversal) is used to compensate for incorrectly wired, balanced cables, to prevent signal cancellation
when a source is dual-mic’d from opposite directions, or to reverse left/right with microphones in a mid-side (MS) configuration.
Delay
Input delay may be used to compensate for ‘phasey’ sounding audio because of time-of-arrival differences between sound sources,
such as a boom mic and wireless radio mic picking up the same sound source.
NOISEASSIST (Requires Plugin)
Sets the amount of noise suppression applied to a channel. Adjust from 0 dB (no suppression) to -20 dB (maximum suppression) in
1 dB steps. Only available when the channel is selected in the System > NoiseAssist menu.
Linking
All MixPre II’s can link channels 1 and 2 either as a stereo pair, mid side pair, or turn linking off.
