3.0 Rear Panel
1. Power Supply Input
Connect the included JBL power supply here.
2. Firmware Update
The USB connector allows you to connect your computer to the mixer for updating the firmware.
To retrieve the firmware version of your mixer, observe the LEDs on the rear panel while the mixer
boots. The LED in the SOURCE 1 section represents major. The LED in the SOURCE 2 section
represents minor. The LED in the SOURCE 3 section represents build. The LED beside the MIC
connector represents revision. Each LED will flash green a number of times for the numeral it stands
for. The format is “major.minor[.build[.revision]]”. For example, if the first released version is “v1.0.0.0”,
when you switch the mixer on, the LED in the SOURCE 1 section will flash green once, and the
remaining LEDs will turn red. The unit is then ready for use.
3. Crossover
This switch activates the crossover feature for the left, right, and subwoofer ZONE outputs. When the
crossover switch is “in”, the left and right outputs will allow frequencies above 125Hz to pass and the
subwoofer output will allow frequencies below 125 Hz to pass. When the crossover is switch is “out”,
the left, right, and subwoofer outputs will pass full-range audio to allow the end-user to utilize the built-
in crossover functionality on their speakers, if desired. Use this crossover feature if the bass response
of your room is too boomy when you are using inexpensive loudspeaker transformers or in conjunction
with the subwoofer crossover (see subwoofer crossover section).
4. Zone Output(s)
The mixer ZONE outputs utilize balanced Euroblock connectors. These outputs carry the Left, Right,
and Subwoofer signals. Connect these outputs to your power amplifier(s).
5. AutoWarmth™ Indicator and Trim Pot
These indicators flash green when the AutoWarmth function is triggered. This trim pot adjusts the point
at which the signal level must drop to before AutoWarmth™ will kick in (referred to as threshold).
