NOTE!
Minimum amplifier load is 2 ohm in stereo mode,
lower impedances may damage the amplifier.
NOTE!
Minimum speaker impedance in bridged connection
is 4 ohm, this connection gives a 2 ohm load with a
4 ohm subwoofer. The load is halved when
connected in bridge mode.
Do
NOT use subwoofers with lower impedance
than 4 ohm.
Connect s to R ch+ and speaker - to L ch -.
Filter settings CH R/L for 2-channel stereo use
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 .
Filter settings CH R/L for subwoofer use
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.
When using the amplifier
for subwoofers, set the
HPF -switch to position FULL .
