Subwoofer - DLS XM20 Owner's Manual

Speaker wiring XM20
Two fullrange speakers to channel 1 / 2
+ CH2 -
BRIDGEABLE
NOTE!
Minimum amplifier load is 2 ohm in stereo mode,
lower impedances may damage the amplifier.
Filter settings CH 1/2 for 2-channel stereo use
The high pass filter (HPF)
blocks very low frequencies
from reaching the spea-
kers. It is mostly used to
protect small speakers ( like
5 inch and smaller ) from
deep bass.
Set the swich in position HPF to activate the filter.
Adjust with the HPF control after your own taste,
a normal setting is 50 - 70 Hz.
The filter can be set at FULL position if you want to
run the amplifier in full range mode without limiting
the frequency range.

One 4 ohm subwoofer bridged
+ CH2 -
BRIDGEABLE
NOTE!
Minimum speaker impedance in bridged connec-
tion 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 speaker + to CH2+ and
-.
speaker - to CH1
Filter settings CH 1/2 for subwoofer use
The low pass filter (LPF)
is mostly used for subwoo-
fers. It will allow low fre-
quencies only and blocks
higher frequencies.
A typical setting is 60 –
70 Hz.
Set the switch to LPF position to activate the filter.
Use this position when conncted to a subwoofer.
Set the switch to FULL position if you want to run
the amplifier in full range mode.
