JBL MPC-X100 100 Hz IV. Typical configurations

Inserting the resistor networkThe factory preset frequency is 20 kHz. If there is a

resistor network already installed in the socket, carefully pull it straight out. Insert the pins of

the new resistor network into the socket holes and carefully press the network into the socket.

Be careful to avoid bending the pins of the resistor network. Orientation of the resistor

network is unimportant, as long as all 8 pins are well seated in the socket.

CD Horn Equalization (Boost)In addition to enabling the 100 Hz high-pass filter at

J202, if you opt for CD horn equalization you must place a jumper at J203 as well. The MPC-

X100 offers two equalization curves for CD horn correction:

 For +6 dB of boost at 20 kHz, place the jumper across pins 1 and 2 of J203.

 For +10 dB of boost at 20 kHz, place the jumper across pins 2 and 3 of J203.

 To bypass the CD horn equalization, do not place a jumper across any pins on J203.

IV. Typical configurations

Applications: Subsonic filters are commonly used in sound installations to filter out rumbles

and other inaudible or unwanted low frequency signals and to protect speaker tuned vented

speakers from damage due to excessive energy below the tuning frequency.

For a subsonic filter, determine the lowest useable frequency that the speaker can safely

handle and set the high-pass filter to that frequency. Typical subsonic filters are set at 50 Hz,

40Hz, 30 Hz or 20 Hz.

Program settings:

1 Set J102 to enable the high-pass filter by placing jumper across pins 2 and 3.

2 No jumper on J103.

3 Insert proper resistor network in RN104 socket.
