NOTE!
Minimum amplifier load is 2 ohm, this connection
gives a 4 ohm load with a 4 ohm subwoofer.
For power wiring, see page 4
For High or low level input wiring, see page 5
NOTE!
The speaker
terminal has dual +
and - terminals for
easier connection if
you have more
than one sub-
woofer. They are
internally conn-
ected in parallel
and can not be
bridged.
The low pass filter (LPF)
is mostly used for
subwoofers. It will allow
low frequencies only and
blocks higher frequencies.
A typical setting is 60 –
70 Hz.
Set the switch to ON position to activate the filter.
Use this position when conncted to subwoofers.
Set the switch to
OFF position if you want to run the
amplifier in full range mode.
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.
If you use the amplifier for subwoofers, set the switch
to position
FULL .
