Channel Safe During Scene Recall
When a Scene is recalled, it sets all the controls to the settings saved with the Scene. There
may be times you do not want to change a specific output channel, or channels. The default
position, Recallable, allows the scene to recall the saved settings. The Safe position does not
allow the scene to change any settings of this channel.

Refer to "Using TouchMix with QSC Amplifiers and Loudspeakers" on page 9 and "QSC GXD Amplifier Settings" on page 10 . Also see "What
is a Channel Preset?" on page 2 for information on preset voices for QSC E-Series loudspeakers.
Aux Pick-off
Pre Fader Post Fader Pre All Pre Dynamics
Available for the Aux mixes only, these buttons determine whether the point from which the signal is taken is before or after the channel fader. For
most monitor mixing applications, this should be set to Pre Fader.
Assignments DCA 1 Mute 1
These buttons assign the output to a Mute Group or a DCA Group. Refer to "Mute Groups" on page 6 and "DCA Groups" on page 6 for details.
Recording
TouchMix mixers make it easier than ever to capture a live performance in a stereo or a multi-track recording. All you need is a USB hard-drive.
NOTE: Hard-drive requirements – A list of hard-drives that QSC has qualified may be found at qsc.com. There are far too many
hard-drives available for us to test them all so there are certainly many unlisted drives that will work well with TouchMix. Higher speed
drives (>7200 RPM) tend to work best. Some higher speed drives don’t do their best when powered from the USB port but will work
when used with an external power supply. We have also had very good luck with solid state drives. USB thumb-drives may work for
recording a small number of channels but are not recommended although users report good results with better quality, USB 3.0
thumb drives.
Formatting the drive
The drive must be formatted as FAT 32 and de-fragmentation improves seek time.
If formatting the drive from an Apple Mac computer select MS-DOS (FAT) as the Format and MBR (Master Boot Record) as the scheme.
The TouchMix mixer can also format a drive. The format function is available from the Recording Setup screen.
Drive space for recording
Be sure that there is sufficient space on the drive for your recording. To calculate the space required for your recording…
• For 48 kHz – Space required (in MB) = 11.5 x minutes x tracks
• For 44.1 kHz – Space required (in MB) = 10.6 x minutes x tracks
It is good practice to have more disk space available than you need. If the drive is nearly full, TouchMix has to look for nooks and crannies of
available space. This will result in fragmented wave files and potential loss of audio data and synchronization across tracks. At approximately 3
hours of non-stop recording, the maximum file size supported by FAT32 is exceeded. To avoid problems, stop and then resume recording. It is not
necessary to create a new session. The TouchMix displays a pop-up that warns you when this limit is approaching. If you do exceed the FAT32 limit,
track synchronization may be lost.
NOTE: Depending on the number of tracks recorded and the performance of the hard drive, multi-track playback may slow down the
rendering of objects on the mixer screen resulting in lagging display of control movement.
