Setting Auto-Gain On Showbox - Mackie SNOWBOX Owner's Manual

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

SETTING AUTO-GAIN ON SHOWBOX:

Here is how to set up auto-gain in seven easy steps:
1. Select the channel.
2. Press-and-hold the volume/gain knob down for two seconds in order to enter "auto-gain listening mode".
Note: this works whether the channel is in 'volume' mode or 'gain' mode.
3. The LED to the left of the 'gain' silkscreen will illuminate solid white and the LEDs surrounding the volume/gain
knob will slow flash white. ShowBox is now awaiting your input... ten seconds, get on it!
4. ShowBox will listen to the input and determine the best gain setting for that input after 10 seconds has elapsed.
It may be difficult to do, but please try and keep your voice (and/or instrument) at the level you plan
to sing/play. Otherwise, auto-gain may have a difficult time with a voice/instrument that raises and lowers
often in a 10-second period!
5. The LEDs surrounding the volume/gain knob will display the position of the gain knob – in real-time – as the auto-gain
is adjusted during the "listening" period.
The gain is unable to be adjusted manually during the "listening" period.
6. Once the gain has been decided on, the LEDs surrounding the volume/gain knob will quickly show the position
before flashing all gain LEDs – first slowly, then quickly – before reverting back to volume mode and its green LEDs.
7. On the bottom of the breakaway mixer is a CliffsNotes® version of how to quickly set auto-gain... or you could always
come back here and read the whole shebang!
As you might suspect...
Any manual adjustments to the gain will erase the set auto-gain and revert back to manual operation, and...
...auto-gain listening mode may be accessed and overwritten at any time by holding down the knob for two
seconds.
Have you had enough talk about gain? We sure have, so let's move onto another favorite topic of ours... volume!
Volume is the last control in a channel's signal path, and it adjusts the level of each channel onto the main mix. As mentioned
earlier, by default, this knob is always on 'volume'. The volume knob ranges from -∞ (OFF, knob far-left) to +10 dB of gain
(MAX, knob far-right). Unity is at 12 o'clock (noon, first five LEDs illuminated).
The default position for the volume knob is 1:00 o'clock (first six LEDs 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 the volume.
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.
