– Channel Label

This simply labels which channel is associated with the channel strip. Click in the label to edit the channel
name.
– Channel Level Meter
This is a peak reading, high-resolution, fast PPM meter. It shows the post converter level of the input signal of
the associated channel. The peak hold bar indicates the highest level seen on the channel since the last reset.
You can reset the hold by clicking on the meter. These meters are simply high resolution versions of the meters
shown on the front panel of the box – all the meter data is generated by the Mobile I/O hardware.

Optimizing Input Levels
The Analog to Digital converters (ADC) in most devices function best when the peak level is around -6
dBFS (lowest distortion, best sound). This is also true of the ADCs in Mobile I/O. Since you have full
level control of the input with the gain trim knob, you will find that you get the best quality recordings
if you try to set the nominal peak level of the input at about -6 dBFS. In addition to providing the best
recording quality, it has the added benefit that you will be operating with an extra 6 dB of headroom
before clipping. There is no drawback to optimizing your levels in this way, and plenty of benefit.
Analog Input Channel Link

In addition to the channel specific controls, each channel pair shares a Link button. When the Link button is
engaged, the trim-value is set to 0 and changes made to one channel of the pair will automatically be applied
