Product Research


Overview: The MAX Module Assortment Kit for Crossovers and PFM Filters contains 60 resistor modules and 10 blanks for creating custom modules. These modules can be used in Audio Control products, such as the 2XS or 6XS, for frequency programming of crossover and PFM filters. The modules come in a handy 30-drawer storage case.

Supplied Modules: The kit comes with both 18dB/octave and 24dB/octave modules in the following frequencies (quantities in parentheses):

18dB per octave24dB per octave
20 Hz (3)35 Hz (2)40 Hz (2)50 Hz (3)60 Hz (5)
50 Hz (3)60 Hz (4)70 Hz (5)70 Hz (5)80 Hz (2)
80 Hz (2)120 Hz (2)150 Hz (3)150 Hz (3)250 Hz (2)
270 Hz (2)500 Hz (2)3.0 kHz (2)500 Hz (2)3.5 kHz (2)
4.5 kHz (2) 4.5 kHz (2) 

Blank Modules: Ten blank modules are included to allow you to make your own custom modules. There are five 18dB/octave module blanks, each requiring 7 resistors, and five 24dB/octave module blanks, each requiring 8 resistors. The use of 5% carbon film resistors is recommended, or 1% metal-film resistors for better accuracy. A guide to module resistor values is included.

Storage Case: The MAX Module Assortment Kit comes with a handy gray plastic storage case with 30 clear-plastic drawers. All but 6 of the drawers are labeled. Extra labels are included for custom-made modules in selected frequencies. The storage case has 2 keyhole slots for wall mounting.
