The input channel strip is the fundamental element in the mixing window. This is where an audio signal is routed, processed, and then sent to either a mix bus or the master channel. An input channel strip can be mono or stereo.
- New in Mixbus v6 are the positions of the Polarity and VCA assign buttons. They are now always displayed at the bottom of the channel strip.
The features of the input strip include:
- The Rec/Input switcher – see section Rec/Input (“Switcher”) Section
- The redirect box – see section Redirects – Plugins, Sends & Inserts
- The EQ section: see section EQs
- EQ “IN” – Enables the EQ section
- 3 EQ bands, each with +/-15 dB gain:
- low and high bands are shelving with adjustable corner frequency
- the midrange band is parametric with proportional-Q peaking ( Q increases with additional boost/cut ) with frequency and cut/boost variable
- highpass filter knob – changes the the highpass filter corner frequency
- filter is second-order ( 12 dB/octave ) and always enabled when the EQ is enabled
- Mixbus Sends Section: see section Bussing
- 8 mixbus sends, each with On/Off switch, and level control
- Stereo Pan Knob
- Master Bus Assign (“Mstr”) : when this is lit, the signal will be sent directly to the Master bus (in addition to any mixbus assignments) post panpot
- Channel Mute and Solo
- Input Trim knob : the input trim value is applied immediately after track playback, and BEFORE any plugins in the redirect box
- Meter : the channel meter is a digital peak-reading meter; the scale is the same as the fader and the compressor threshold
- The Compressor Section: see section Compression Techniques
- Comp “IN” – Enables the compressor section
- Makeup Gain – provides up to 10dB of Makeup Gain; this gain is only active when the compressor is enabled
- Threshold – the threshold indicates when the compressor will begin working on the signal; reduce the threshold slider to compress more
- Gain-Reduction meter – indicates gain reduction, in 1dB increments
- “Speed” & “Mode” knobs : see Compression
- Fader level : this displays the curent fader position, in dB. Click to enter a value.
- Meter peak-hold : this displays the loudest digital-peak value that has been detected by the meter. It turns red when the value is over 0dBFS. Click to reset the value.
- Fader Automation selector : select between Manual, Play, Write, and Touch. This control only affects the channel’s fader
- Group selector : click this button to assign the channel to a Group ( see: Groups )
- Meter Position selector : click this button to select the meter position ( Input, Pre-Fader, Custom, Post-Fader, Output )
- Polarity switch
- VCA Assign
There is an additional method for displaying the Rec/Input menu on the channel strips. Rather than clicking the button on the channel strip, the View pulldown menu provides either a menu click or keyboard shortcuts for switching the display. The display changes for ALL channels, not just a selected channel. The figure below shows how to access this control and also shows the associated keyboard shortcut.
Other Buttons and Controls
- Click this button to invert the signal’s polarity. On a stereo channel, you will see 2 polarity switches, one for each channel.
- Click this button to assign one or more VCA faders to control this channel’s fader and mute. See the section VCA Strip for details.
- Grouping links faders together for common control. Click this button to assign this channel’s fader to a group. See the section Groups for details.
- Click this button to select the desired fader automation mode. The choices are Manual, Play, Write, Touch and Latch. See the section Fader, Pan and Plug-in Automation for details.
Channel strip operation is the same as everywhere in Mixbus.
- mouse left-click on a button to activate it
- to turn a knob or move a fader, click and hold on it and move the mouse up and down
- double clicking on most knobs will snap it to its centre position, 0dB position (3 o’clock) on a mixbux level knob
- right-clicking on the channel slate will bring up a menu where you can change the name, colour, input or output routing, and other options:
- right clicking on the compressor button allows you to select between leveller, compressor or limiter operation:
