L2404-USB

USB MIXER

12

Peak LED

The Peak LED lights up when the level coming into that channel is too loud. If you see this light flash, 
turn that channel's Gain control down and the Level control up.

13

Mute LED and Button

Press this button to mute the channel. If the LED is lighted this means that you have the button pressed and 
that the channel is muted and there will be no audio sent to the main mix and post-fader buses. Pre-fader 
aux sends are unaffected by the mute switch.

14

Fader

This controls the volume level of the channel coming into the mixer. Once you have the gain level set 
to not distort the input you should use the fader to control the volume of the input channel.

15

Channel Assignment Buttons

These buttons determine where the input channels are routed. Pressing the Sub 1-2 button will send 
the channel to Subgroup 1 and 2. Pressing the Sub 3-4 button will send the channel to Subgroup 3 
and 4. Pressing the MAIN L-R will send the channel to the Main Mix.

16

Solo

This Solo button allows the user to route the channel signal to the solo bus. This allows you to listen 
to the selected channel's signal without affecting the main output signal. The signal is either routed 
pre-fader or post-fader, depending upon whether or not the Solo Mode button is pressed. You can 
read more about solo mode in section 32.
