{{ToneMatch Mixer Gain Staging and ToneMatch Preset}}


===== Set Up Your Source =====
Set your source at the maximum that it will be when performing.
* Microphone
:Sing directly into the microphone using close microphone technique (lips just brushing the windscreen). Sing as loudly as you will sing during your performance. You want to set the Trim to work at your maximum volume.
* Instrument
:Turn your input as high as it is likely to go during performance.
===== Trim Controls =====
The {{ToneMatch Mixer}} trim controls for Channels 1-4 (1-8 for the {{T8S}}) provide a significant gain increase when you reach the upper limit. This increase in gain is normal operation.
Most sources like typical microphones and piezo pickup systems can provide enough level without the need to add significant gain from the trim control. Certain sources like passive acoustic guitar pickups require additional gain and in these cases it can be necessary to set the trim level to the upper range of the control. When the trim control is set this high you may notice the gain change. This is normal operation. If you want to run the trim control at lower settings we recommend using a preamp or simple stomp box level booster.
The trim for Aux input channels 5/6 (9/10 for the {{T8S}}) do not exhibit the same behavior as the trim controls for Channels 1-4 (1-8 for the {{T8S}}).  The Aux inputs are designed for line level sources and do not have the same gain staging as channels 5/6 (9/10 for the {{T8S}}).

===== Set Input Trim =====
Turn the Trim setting up until the Trim Light is solid green with occasional flickers of yellow. Use the Trim lights as your guide. (The exact position of the Trim knob is not important).

Sometimes the geometry and configuration of the mic(s) will cause one particular frequency to be reinforced more than all the others, relatively independent of the positioning of the microphone.  By identifying that particular frequency, one can use the T1® to reduce ("notch out") just that one particular "problem" frequency.
