The DLS RA50 amplifier include high pass filter (HP),
low pass filter (LP) and subsonic filter.
The slope of all filters are 12 dB / octave (subsonic 18
dB). The filters can be switched off if you want to run
the amplifier in full range mode. Some of the filters
can be used on different frequency ranges by the use
of multiplication switches.
The filter configuration on the respective channels can
be found in the technical specifications.
The HP-filter ( high pass filter )
blocks very low frequencies from
reaching the speakers. It is
mostly used at say 60 Hz to
protect small speakers ( like 6
inch and smaller ) from deep
bass.
High Pass Filter
Low Pass Filter
The LP-filter ( low pass filter) is
mostly used for subwoofers. It will
allow low frequencies only and
blocks higher frequencies.
A typical setting is 50 – 80 Hz.
The filter can be switched IN-OUT.
The LP-filter on ch 1&2 has an-
other frequency range used for
other applications.

The x-over frequency is 25 Hz.
Filters on CH 1 and CH2
CH1 and CH2 include high pass filter (HP) and low
pass filter (LP).
The slope of the filters are 12 dB / octave. The filt-
ers can be switched off if you want to run the
amplifier in full range mode.
The LP-filter can be used in two different frequency
ranges by changing a switch in the bottom plate of
the amplifer. The switch has two positions giving
the following frequency ranges:
x1 = 250 - 700 Hz
x10 = 2,5 kHz - 7 kHz
The LP-filter is used when running a 2- or 3-way
system in active mode. See the examples later in
the manual.
