NOTE!
Minimum amplifier load is 2 ohm, lower
impedances may damage the amplifier. This
connection gives a 2 ohm load with two 4 ohm
subwoofers.
The low pass filter (LPF)
is used for subwoofers.
It will allow low
frequencies only and
blocks higher frequencies.
A typical setting is 60 –
70 Hz.
The LPF filter can not be switched OFF .
The high pass filter (HPF)
blocks very low
frequencies from reaching
the speakers. It is mostly
used to protect small
speakers ( like 5 inch and
smaller ) from deep bass.
Set the swich in position 70 Hz or 90 Hz to activate
the filter. Test which setting sounds best.
The filter can be set at
FULL position if you want to
run the amplifier in full range mode without limiting
the frequency range.
