• A multi-channel system can be set up using a
combination of filters. The inductance (L) and
capacitance (C) will determine the frequency (fc)
that the speaker will reproduce. Refer to the chart
below to determine the components required.
• Use the capacitors specified. Non-polarized
capacitors rated at over ±25 V should be used for
C1 and C2 in the diagram. Because of the voltage
output of the amplifier, it is very important to use
non-polarized capacitors rated at or over 25 V.
This will prevent a safety hazard.
