Kappa 52a

INSTALLATION (continued)
3. Make sure the wires are firmly seated in the Weco 2-pin connector and that each screw is completely tightened. Insert the wired connector into the POWER socket on the amplifier. Press it in until it stops. 4. Using the Weco 5-pin connector, connect a blue wire from the source unit�s remote connection to the REM terminal. Depending on polarity requirements (e.g., bridged-mono or tri-mode configurations � see Figures 1 through 3 on page 3), connect speaker wires from the speakers to the L and R (+ and �) terminals, as required by your system plan. 5. Make sure the wires are firmly seated in the Weco 5-pin connector and that each screw is completely tightened. Insert the wired Weco 5-pin connector into the 5-pin socket on the amplifier. Press it in until it stops. 6. Connect RCA cables from a source unit to the L and R INPUT jacks.

SETTING INPUT SENSITIVITY...
Initially, turn the input sensitivity GAIN control to its minimum (counter-clockwise) position (refer to Figure 8). 1. Reconnect the (�) negative lead to your vehicle�s battery. Apply power to the audio system and play a favorite music track from CD or tape.
NOTE: After the source unit is on, green LEDs (on the top pane)l will illuminate, indicating the amplifier is on. If not, check the wiring, especially the remote connection from the source unit. Also refer to �Troubleshooting� on the next page.

2. On the source unit, increase the volume control to maximum position. Slowly increase the GAIN control (clockwise) towards three o� clock and, at the same time, listen to the quality of the reproduced sound. At some point, you�ll hear distortion on the music peaks. Stop the adjustment and turn it back slightly.

SETTING THE CROSSOVER...
IMPORTANT: If you plan to use the Kappa 52a to drive full-range speakers, set both AMP and AUX filters to FLAT (refer to Figure 1 on page 3 and Figure 8 below) and skip to the next section, �Setting Input Sensitivity�.

INSTALLING THE CONTROL COVER...
After wiring and testing the Kappa 52a amplifier, install the control cover using the enclosed machine screws to deter tampering and help seal out dust.
NOTE: Do not over-tighten the machine screws. Doing so may crack the cover.

1. Set the CROSSOVER control to the frequency recommended by speaker manufacturer (refer to Figure 8). If the value is unknown, set the control midway. If needed, adjust the X1/X10 switch to obtain the proper value.

Figure 8. Kappa 52a controls for crossover, input, and output.

2. Depending on your system plan, set the AMP and AUX switches to LP (low-pass), HP (high-pass), or FLAT (refer to Figure 8).
