**Installing the Compact Power Amplifier

**

Wiring Step 1
If you are connecting the sound sources directly to the projector, follow the suggested Option A wiring diagram (Figure 1) for reference.
If you are connecting the sound sources directly to the JIB/PA50 Power Amp and are using the external volume control, follow the suggested Option B wiring diagram (Figure 2) and 10k Pot Volume Wiring Diagram (Figure 3) for reference. Step 2

1. Use standard RCA connectors and/or 1/8″ (3.5mm) mini-cables to connect the input devices (e.g., the projector, other audio sources) to the power amp.
   Match the wiring polarity. For example, red for positive, black or white for negative.
   Make sure no wire strand bridges (shorts) the adjacent terminals.

2. Insert all four wires on each speaker into the blue 4-pin captive screw plug supplied with the power amp.
   Use a #1 Phillips screwdriver to tighten the locking screws.

3.  Insert the captive screw plug into the receptacle on the amp’s rear panel (see drawing).

4. Attach the power amp plug to the amplifier.
   Do you need to wire the 10k pot volume? If Yes, proceed to Step 3 below

Step 3
When wiring the 10V, Vol/Mute and GND outputs, strip off the insulation from the external volume control wire by 3/16″. Make sure the wire ends do not touch. Keep
exposed wire ends short after stripping. If the wires touch, they may short the amp.

1. Follow the 10k Pot Volume Wiring Diagram to connect the external volume control to the amp (Figure 4).

2. Insert all three pins from the external volume control into the green 3-pin captive screw plug supplied with the amp (see drawing).
   Use a #1 flat blade screwdriver to tighten the locking screws.

3. Insert the captive screw plug into the receptacle on the amp’s rear panel (Figure 5).

6. Turn the Input 1 control counter-clockwise until the distortion disappears.
7. Adjust the projector volume until you reach the desired sound level.

If you are using the Option B wiring method of installation on page 3, do the following:

1. Insert a #1 flat blade screwdriver to the Input 1 control.
2. To test the volume, use the screwdriver to gently turn the Input 1 control on the amp counter-clockwise to the end (Figure 6).
3.  Turn the Input 1 control clockwise 1/4 turn.
4. Turn the 10k pot volume to the maximum level.
5. Play sound through all the audio inputs on the amp.
6. Choose the loudest audio source to help adjust the amp volume.
7. Turn the Input 1 control on the amp clockwise slowly until the sound distorts.
8. Turn the Input 1 control counter-clockwise until the distortion disappears.
9. Adjust the 10k pot volume until you reach the desired sound level.

After setting up the Input 1, let the sound continue to play and proceed to the “Input 2 Setup” section on page 6.
Input 2 Control Setup

1. Attach a device such as a wireless microphone to the amp input.
     Be sure the mic is turned on.

2. Insert a #1 flat blade screwdriver to the Input 2 control.

3. Use the screwdriver to gently turn the Input 2 control on the amp counterclockwise to the end (Figure 7).

4. Turn on the mic receiver, if applicable.

5. Have someone stand in the desired presentation location and speak into the mic.

6. Turn the Input 2 control clockwise until you reach the desired sound level.

7.  Test feedback by having someone walk around the room and speak into the mic.
   Is there feedback coming from the mic? If Yes, turn the Input 2 control counterclockwise until the feedback is gone.

8. If No, continue to step

9. Play music through the amp as you test the mic.
