1. LEVEL: Used to set the overall output level.

indicator illuminates. Mono mode reduces the channel count on
the PA or lets you send the signal 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 trouble shooting. Works
with ear buds and standard headphones.

4. POWER INPUT/USB: Used to power the BT-Pro. Connect the
included USB Mini-B cable to a computer or wall power supply. This
is a power input only that will not pass audio or other data.

5. XLR OUT: Standard XLR male outputs follow AES format with pin-1
(ground), pin-2 (+), pin-3 (-).

6. GROUND LIFT: Used to help eliminate hum and buzz caused by
ground loops. Lifts pin-1 on both XLR outputs.

7. RIGHT-ISO/LEFT-ISO: Switches on side panel let you insert
transformer isolation when needed on each channel. Use to
eliminate hum and buzz caused by ground loops.

8. COVER: Blue Sintra® cover protects the internal antenna while
allowing the wireless signal to pass through without interference.

9. LED PAIRING INDICATORS: Red
and blue LED’s toggle back and
forth during pairing to provide visual
feedback of the wireless Bluetooth
connection status.
