Principle of Tri-mode
Method of frequency band division using a coil and capacitor•••in case of 6dB/oct. slope
Crossover Frequency
0 dB
-3 dB
L
Example:
When it is required to set a crossover frequency of 120 Hz using speakers with an
impedance of 4 ohms.
Prepare commercially-available coil and capacitor with the closest ratings to the results
calculated from the formula above. The capacitor rating should be as close as possible to
331.25 (µF) and the coil rating should be as close as possible to 5.3 (mH).
2CAUTION
If you wish to bridge-connect a speaker, the speaker impedance must be no less than 4 ohms.
Connecting a speaker with an impedance lower than 4 ohms may damage the unit.
