SHOWBOX BATTERY POWERED ALL-IN-ONE PERFORMANCE RIG WITH BREAKAWAY MIX CONTROL

USB-C Charging Thru Port
This handy hidden USB-C port simply has one purpose in life: to charge a smartphone
or tablet. The plugged-in device can simply remain connected for a charge or use
the device as the Bluetooth connection, or to scroll through sheet music and/or lyrics.
This port emits 2A when the ShowBox is plugged into a live power source and half
that – 1A – when the ShowBox is running off of battery.
CHANNEL select
Channel Select Buttons
These channels align with the inputs on the rear panel of ShowBox. Pressing one of these buttons will select
the corresponding channel for input-based editing. The LED centered on the button of the currently selected channel
will illuminate green – channel 3 in the example above – and all others channels’ LEDs will be off. All stored settings
on that channel will be recalled when selected, including volume, EQ, compressor, FX, and more. Only one channel
may be selected at a time. Thusly, only one channel’s parameters may be updated at a time.

Channel Volume and Gain Knob
This push-button, rotatable knob has a massive amount of responsibilities, but lucky for us,
it’s up to the task! As you can see to the left, this knob sets the gain and volume levels, but did
you know that it also mutes the selected channel? That there is an OL LED in addition to the level
and gain LEDs? Did you know that ShowBox can properly set the gain using its auto-gain feature, too?
Read about all that and more, starting with...
If you haven’t already, please read the “Getting Started” section on page 7. Setting the gain correctly
will ensure that the preamplifier’s gain is not too high, where distortion could occur, and not too low,
where the quieter, exquisitely-delicate passages might be lost in background noise. ShowBox is also blessed with an auto-gain
feature that will set the gain automatically. We will begin by discussing gain, then moving on to volume. Read on...
The gain knob – in conjunction with the overload LED (the far-right LED) – adjust the input sensitivity of the mic and line in-
puts. This allows signals from the outside world to be adjusted to run through each channel at optimal internal operating levels.
By default, this knob is always on ‘volume’. Gain is accessed by a single tap of the volume/gain knob. When tapped, the LEDs
surrounding the volume/gain knob will turn from green to white. Additionally, the LED to the left of the ‘gain’ silkscreen will
illuminate white, while the LED to the left of the ‘volume’ silkscreen will turn off. It will remain in gain mode so long as there
is activity. It will revert back to volume mode after five seconds of inactivity (or another single tap of the volume/gain knob).
The default position for the gain knob is 1:00 o’clock (first six LEDs illuminated). The far-right – ninth – LED illuminates
white (if at max gain). 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 the gain.
Quickly double-tapping the volume/gain knob will mute the selected channel. The LEDs surrounding the volume/
gain knob will flash when muted. [Green if double-tapped when volume is shown, white if double-tapped when
gain is shown.]. The LED to the left of the volume silkscreen will illuminate solid red. Single- (or double-) tap the
volume/gain knob to un-mute the channel.
Now that you are familiar with what gain is and how to access it, let’s talk about a really cool feature on ShowBox: Auto-gain.
That’s right, ShowBox will set the gain automatically for inputs 1-5/6.
