PA55/BT Control Panel

OVERVIEW: CONTROLS & FUNCTIONS BACK PANEL:

INPUT SECTION:

This is where you may plug in microphones, instruments, keyboards, drum machines and other audio devices, adjust the 

volume, bass and treble.

1.

MIC Inputs:

 These XLR inputs are designed for low-impedance microphones or equipment that has a mic-level, balanced

output (often called a Direct Out). Note: These inputs receive 15-volt phantom power. This is used to provide power to

condenser microphones. Phantom power will not damage any dynamic or non-condenser microphone.

2.

LINE Inputs:

 These ¼-inch inputs may be used to connect high-impedance microphones or keyboards, drum machines

and other audio devices.

3.

AUX IN:

 Use this stereo input to connect an external audio device such as an MP3, CD player or computer for playback.

Note: Right and Left channels are summed to mono on this input.

4.

Volume:

 Use these controls to adjust the volume level of each channel and the relative balance between them.

5.

Low:

 Determines the emphasis of bass frequencies. Turning this knob clockwise creates a deeper, warmer tone. If you

need a brighter sound, reduce the bass by turning counterclockwise.

6.

High:

 Turned clockwise, this control accents treble frequencies to produce clearer, crisper sound. Turn counterclockwise

to make the sound softer and less bright.

7.

Master Volume:

 Controls the overall volume of all channels and input on 

SYNC

 Note: Does not affect SYNC Output

 

level.

8.

SYNC IN:

 This balanced XLR Jack accepts the 

SYNC

 output from another PA55/BT using a standard

mic cable. Channels from both PA55/BT's are summed together. Use the channel volume controls to get the mix of the 6

channels (If a channel is not used turn the volume all the way down).  MASTER volume controls the loudness of the

mix

through its PA55/BT. It does not affect volume of synced PA55/BT. Note: The shield connection (pin 1) on this jack is

connected to chassis ground. It is not lifted.

9. SYNC OUT:

 This balanced XLR Jack accepts the 

SYNC 

input from another PA55/BT using a standard

mic cable. Channels from both PA55/BT's  are summed together. Use the channel volume controls to get the mix of the 6

channels (If a channel is not used turn the volume all the way down).  MASTER volume controls the loudness of the mix

through its PA55BT. It does not affect volume of 

synced

 

PA55/BT. This jack may also be used to connect the PA55/BT to a 

power amp with a balanced line input. Note:  The shield connection (pin 1) on this jack does not connect to chassis ground. It 

is lifted.

10. Subwoofer Out:

 The PA55/BT subwoofer output jack sends a line level unbalanced low frequency signal crossed over at

150Hz to a PA112-S powered subwoofer. It will also work with any powered subwoofer that accepts a line level input. A

crossover that rolls off the frequencies below 150Hz through the PA55/BT’s speakers is activated when using this jack with

 

a

standard ¼” mono (tip/Sleeve) SHIELDED instrument cable. When Subwoofer jack is not used, this crossover is bypassed

and PA55/BT speakers are full range. Note:  It is recommended to connect subwoofer using a standard ¼” mono (tip/sleeve) 

SHIELDED instrument cable because the sleeve connection to ground activates crossover on PA55/BT speakers. When 

possible, plug AC cable on PA55/BT and Subwoofer into same outlet or power strip. This will prevent possible ground loop 

hum through the system.

11.

Power:

 T

his switch activates AC power to the powered PA.

12.

AC Power Cord Receptacle:

 Insert the PA55/ BT’ s AC cord firmly into the AC receptacle. Be sure to use the

cable provided with your PA55/BT. The power cord can be removed for storage or replaced if damaged. Note: Replace

 

the

 

AC cord if its protective jacket is damaged or ground pin is damaged or removed.

13.
