Principle of Tri-mode
Method of frequency band division using a coil and capacitor...in case of 6dB/oct. slope.

0 dB

L=
(mH)
C=
fc
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.
• Be sure to connect capacitors to speakers to which high frequencies will be passed.
Failure to do so will result in a drop of the combined impedance with the subwoofer.
• Ensure that the withstand voltage and current ratings of the capacitors (C) and coils
(L) are sufficient.
