Subwoofer - DLS Reference RM10 Owner's Manual

Speaker connections to RM20
Two full-range
speakers, coaxial
or component,
connected to left
& right channel.
NOTE!
Minimum amplifier load in stereo is 2 ohm, lower
impedances may damage the amplifier.
Filter setting LPF low pass filter
The low pass filter is
mostly used for
subwoofers. It will allow
low frequencies only and
blocks higher frequencies.
A typical setting is 50 –
70 Hz.
The Subsonic filter
blocks the very deepest
frequencies from reaching
the subwoofers. It can be
set from 15 to 150 Hz and
can be switched on / off.
A typical setting for
subwoofer use is 25-30
Hz
The high pass filter can also be used to block 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.

For high or low level input wiring, see page 5

One 4 ohm

subwoofer

connected in
bridge mode
to the outer
connections of
the speaker
terminal.
NOTE!
Minimum amplifier load in bridge mode is 4 ohm.
This connection gives a 2 ohm load with a 4 ohm
subwoofer (the load is halved when connected in
bridge mode).
BASS EQ
is used to increase the bass
BASS EQ
volume at a low frequency.You can
select the amplification between 0 dB (
no amplification ) and +6 dB ( full
amplification ) at 80 Hz center frequency.
This function is used to compensate for
the bass function on your front system
and adjust for your own taste of bass.
Set level control at 0 dB if you want it to
be inoperative.
