It is best practice to set your input volume (gains) in this manner:
1. Unplug all inputs except for the one you wish to set the gain for. In this instance, the
LINE INPUT RCA jacks.
2. Set the line-level input device volume (smart phone, tablet, MP3 player, etc.) to 60%.
3. Slowly turn up the LINE INPUT volume control. As soon as the clip indicator LED goes
on or you hear any distortion – turn it down one or two notches.

A. Because mixers feature two volume controls (channel and master), when con-
necting one via the XLR line in port, the procedure is slightly different. Set the BPA’s
LINE INPUT volume to 50% and set the mixer master volume to 50%. Make the
adjustments in step 3 on the mixer channel level control. If after making these ad-
justments the signal still isn’t strong enough, you can additionally boost the signal
by turning up the BPA’s LINE INPUT control.
B. When adjusting the MIC INPUT volume control, you must speak into the micro-
phone and adjust the control as needed. This is because adjustments to the mic
input are a matter of mic volume in relation to the music volume and not necessarily
a clipping issue.
Your BPA features balanced microphone input via XLR or ¼˝ TRS inputs.
1. Switch OFF your BPA.
2. Plug your microphone into the ¼˝ TRS or XLR jack.
NEVER USE BOTH PORTS
AT ONCE.
Make sure the LINE/MIC switch is set to MIC.
3. Switch ON your BPA.
4. Refer to the “Setting Level Controls” section of this manual for instructions on how to
properly adjust the input volume (gains).
Always stand behind the BPA when making your microphone adjustments to avoid feed-
back distortion.

You can use the MIC/LINE INPUT XLR port to connect a mixer. Use the RCA and 3.5mm
AUX inputs to connect an additional stereo signal source such as a smart phone, tablet,
MP3 player, CD player, etc.
1. Switch OFF your BPA.
2. Connect the input source unit to the 3.5mm input, RCA jacks, or XLR input.
ONLY
USE ONE INPUT AT A TIME.
If using the XLR port,
make sure the LINE/MIC switch is
set to LINE.
3. Switch ON your BPA.
