MPC-XU

2-Way Active Crossover

This configuration routes the frequencies below a particular frequency to amplifier Channel 1, which will driver the low-frequency speaker(s), and the frequencies above to Channel 2, which will drive the high-frequency speaker(s). Using the MPC-XU as a crossover requires that you drive both amplifier inputs with the same full-band signal.

Program settings:

1On the input module, set the amplifer mode to parallel. Alternately, you could use a Y- cable to provide the same signal to both channel inputs.

Channel 1:

2Set J101 to enable the Channel 1’s low-pass filter by placing jumper across pins 2 and 3.

3 No jumper on J103.

4 Insert a resistor network into RN102 that is appropriate to the desired crossover frequency.

5Subsonic (infrasonic) filter—If you need subsonic (infrasonic) filtering, set J102 to enable the high-pass filter by placing jumper across pins 2 and 3, and insert a resistor network into RN104 corresponding to the roll-off frequency you desire. If you do not want subsonic (infrasonic) filtering, set J102 to disable the high-pass filter by placing jumper across pins 1 and 2.

Channel 2:

6Set J202 to enable the Channel 2’s high-pass filter by placing jumper across pins 2 and 3.

7 Insert a resistor network into RN204 that is appropriate to the desired crossover frequency.

8CD horn EQ—If you need equalization for a constant-directivity horn, set a jumper on J203 for the amount of boost you need. If you do not want CD horn equalization, do not place any jumper on J203.

9Ultrasonic filtering—If you need ultrasonic filtering, set a jumper on J201 across pins 2 and 3 to enable Channel 2’s Low-pass filter and insert a resistor network into RN202 that corresponds to the desired roll-off frequency. If you do not want any ultrasonic filtering, set the jumper on J201 across pins 1 and 2 to bypass the low-pass filter.

Multi-way Crossover System

The MPC-XU allows you to set up 3- and even 4-way systems. Of course, this also requires that you use more than one amplifier and more than one MPC-XU. You must feed each amplifier with the same full-range signal and use the MPC-XU to filter the signals in the individual channels. Each MPC-XU should be configured in the bandpass filter configuration as described above.
