the input volume/gain knob and/or main volume knob.
Quickly double-tapping the main volume knob will display the firmware version of the ShowBox
("base", replacing the FX1 scribble strip) and the breakaway mixer ("UI", replacing the FX2 scribble
strip). The FX will be displayed again after 4-5 seconds. Now that you know how to view the firmware
versions, here's a friendly reminder that you should let the knob remain peaceful, calm and tranquil,
only viewing the fimrware versions if instructed by Tech Support. Thank you for listening!
Located conveniently below the main volume knob is the main mute button. Pressing it mutes all inputs...

volume knob all the way off, and make sure the headphone volume is up. We all have family, friends,
and roomates that don't want to be bothered by our songs, either.

This additional gain will typically never be needed, but it's nice to know that it's there.
As you may have noticed to the left (or on an actual ShowBox), the single-color LEDs
surrounding the main volume knob are green. The default position for the main volume
knob is 12 o'clock (noon, top-centered LED illuminated).
The far-right – ninth – LED illuminates green (if at max volume). However, if the incoming signal
is too hot, this LED will illuminate red to show that the input is clipping. If this occurs, turn down

or doing anything new that may affect the headphone volume. Then turn it up slowly
