Crossover Modules
FOR FM 330 SERIES OF LINEAR-PHASE ELECTRONIC CROSSOVERS
25 High-Pass and 25 Low-Pass crossover modules in the range from 63Hz to 16kHz are available as standard.
FM ACOUSTICS produces any specific crossover frequency to customer request should another frequency than the ones indicated below be required.
Standard crossover frequencies are:
| 63 Hz | 200 Hz | 630 Hz | 0.63 Hz | 2 kHz | 6.3 kHz |
| 80 Hz | 250 Hz | 800 Hz | 0.8 Hz | 2.5 kHz | 8 kHz |
| 100 Hz | 315 Hz | 1000 Hz | 1 kHz | 3.15 kHz | 10 kHz |
| 125 Hz | 400 Hz | 1250 Hz | 1.25 kHz | 4 kHz | 12.5 kHz |
| 160 Hz | 500 Hz | 1600 Hz | 1.6 kHz | 5 kHz | 16 kHz |
Order No: ACC-22000 + crossover Frequency + indication if LP (Low Pass) or HP (High Pass)
Standard crossover frequencies of the filter sections can be varied within the following range:
| FM 332-X100 | Low to high crossover frequency: | 60 Hz | -1600Hz |
| FM 332-X1000: | Low to high crossover frequency: | 0.6 kHz | - 16 kHz* |
| FM 333: | Low to mid crossover frequency: | 60 Hz | -1600Hz |
| Mid to high crossover frequency: | 0.6 kHz | - 16 kHz* | |
| FM 334: | Low to low-mid crossover frequency: | 60 Hz | -1600Hz |
| Low-mid to high-mid crossover frequency: | 160 Hz | - 3 kHz* | |
| High-mid to high crossover frequency: | 0.6 kHz | - 16 kHz* |
* If other Crossover frequencies are required, internal modules that cover other ranges can be installed on special order.

Attention
Resistor Modules cannot be swapped between the FM 122/123 and the FM 222/223 !
They are different types and if an FM 122 module would be used in an FM 223, hum and noise are the result - and vice versa.
Damage occurring from such installation errors are not covered by warranty.
