1. LEVEL: Used to set the overall output volume at the XLR and
headphone outputs.
2. MONO: Sums the stereo signal to mono. When active, the LED
indicator illuminates. Mono mode allows you to reduce the channel
count on the PA or send identical mono signals to two separate
audio systems simultaneously.
3. HEADPHONE: Mini 3.5mm stereo (1/8”) TRS headphone output is
used to check the output from the source for troubleshooting.
4. PAIR/RESET: Press and hold the PAIR button for three seconds to
disconnect from any Bluetooth devices and force the BT-Pro into
pairing mode. Press the recessed RESET switch to power-cycle
the BT-Pro. The red/yellow PAIR LED indicates the pairing and
playback status of the BT-Pro.
5. POWER INPUT/USB: Used to locally power the BT-Pro. Connect
the included USB Type-C cable to a computer or a USB wall charger
(included). This is a power input only that will not pass audio or other
data.
6. XLR OUT: Standard XLR male outputs provide balanced audio
outputs to connect to a PA system. The BT-Pro can be powered
remotely by providing 48V phantom power to these outputs.
7. GROUND LIFT: Used to help eliminate hum and buzz caused by
ground loops. Lifts pin-1 on both XLR outputs.
8. PLASTIC INSERT: The BT-Pro combines a 14 gauge steel outer
shell with an injection-molded plastic insert which allows wireless
signals to pass though unimpeded, enhancing the eective range
of the device while ensuring it handles the stresses of nightly use
on tour.
