Ultrasonic Filter

Applications: An ultrasonic filter is useful for minimizing RF interference, oscillations, leakage or aliasing from digital devices, or other signals that are too high in pitch to hear but may wreak havoc in an amplifier system.

Typical ultrasonic filters are set at 16 kHz or 20 kHz.

Program settings:

1 Set Jx01 to enable the low-pass filter by placing jumper across pins 2 and 3.

2Set Jx02 to disable the high-pass filter (if not using) by placing jumper across pins 1 and 2.

3 No jumper on Jx03.

4 Insert proper resistor network in RNx02 socket.

Bandpass Filter

Applications: A bandpass filter is useful if the speaker system has a limited bandwidth.

Program settings:

1Set Jx01 to enable the low-pass filter by placing jumper across pins 2 and 3.

2 Set Jx02 to enable the high-pass filter by placing jumper across pins 2 and 3. 3 No jumper on Jx03.

4Insert proper resistor network corresponding to the lower limit of the desired passband in RNx04 socket.

5Insert proper resistor network corresponding to the upper limit of the desired passband in RNx02 socket.

CD Horn Equalization Filter

Applications: A constant directivity horn requires a 6 dB per octave boost at high frequen- cies to provide a flat frequency response. On the MPC-XU you must use the CD horn equalization in conjunction with the high-pass filter.

Program settings:

1Set Jx01 to bypass the low-pass filter (if not using) by placing jumper across pins 1 and 2.

2 Set Jx02 to enable the high-pass filter by placing jumper across pins 2 and 3.

3Set Jx03 to select the EQ curve you desire: across pins 1 and 2 to +6 dB at 20 kHz, or across pins 2 and 3 for +10 dB at 20 kHz.

Subsonic Filter with CD Horn EQ

Applications: This would be suitable only if the loudspeaker system uses a passive crossover.

Program settings: Use settings 1, 2 and 4 from the subsonic filter instructions and setting 3 from the CD horn equalization filter instructions above.

Subsonic and Ultrasonic Filter

Program settings: Use settings 2, 3 and 4 from the subsonic filter instructions along with 2 and 3 from the ultrasonic filter instructions above.
