TouchMix-30 Pro FAQ

What is the Patch Matrix, why do I need it & how do I use it?

The patch matrix allows a physical, analog input to be routed to a channel other than the one it is assigned to by default. This may be useful to rearrange the mixer’s layout. Let’s say you’ve got audio coming from video gear and you want to use the mixer’s line inputs (25, 26, 27, 28) because they can accommodate the high signal levels that some broadcast gear outputs. But you’d like the controls for these inputs to show up on fader bank 1-8. The Patch Matrix allows this rerouting.

In addition a single analog input may be routed to multiple channels. This is known as “multing”. Let’s say the band does a song where the singer goes to a “telephone voice” for part of the song. The Patch Matrix can connect the singer’s microphone input to two channels. One can be set normally while the other is adjusted to sound like the singer is talking on a telephone. Then the singer’s voice can be switched between the two using the channels’ mute buttons.

There is a training video on this topic, it is covered in the mixer’s Info System (Misc Features, Patch Matrix) and the User Manual.

What kind of microphone should I use when I use the Room Tuning Wizard? Can I use a vocal mic?

A: Many vocal microphones have a rise in their high-frequency response. For example, an SM58 has a frequency response that rises up to 5 dB between 2 kHz and 10 kHz. If these microphones are used the resulting room tuning will have a corresponding dip. A microphone with fairly flat frequency response will provide good results. There are a number of measurement microphones available at reasonable prices ($100 or less) and it isn’t necessary to use a precision, calibrated microphone. Note that the Talkback input of the mixer has phantom power to support condenser measurement microphones.

Can I move more than “one” fader at a time?

What is “Solo in Place” & how is it used?

Solo In Place (SIP) is a handy function for system set up. SIP mutes all the mixer inputs except the input (or inputs) that is (or are) soloed. The “In Place” part means that the channel is still routed to wherever it was routed before SIP was engaged. It is used as an alternative to manually muting all the channels other than the one the operator is working on. SIP mode may be selected / deselected from the Mixer Setup page. Note that the Cue function functions normally for the outputs when SIP is used.

The Feedback Wizard doesn’t seem to be doing anything. The channel fader isn’t moving.

This can happen if the environment is too quiet or if the only noise in the space is low frequency noise such as air-handling noise. The solution is to apply a little noise using the noise control located on the lower left corner of the Anti-Feedback Wizard screen. One other possibility is that the inputs are muted or that noise gates are preventing input signal from reaching the mixer output.
