Adjustment of the phase
The subwoofer offers extensive adjustment possi-
bilities of the phase relationship for optimal inte-
gration with your main speakers. The phase-control
makes possible variable phase between 0 ° - 180 °,
or 180° - 360°, depending on how the pertinent
switch is set. The regulator and the switch are to be used until the subwoofer
blends in harmoniously with the rest of the system. It makes sense to make the
adjustments at normal listening levels to achieve a meaningful amount of bass.
The optimal adjustment setting can be tested by temporary shifting to the
opposite phase. If the proper phase-adjustment has been made, the exchange
will produce an audible reduction of the bass level (when set to wrong/opposite
polarity at that setting).
Input terminals
The subwoofer offers two Mono inputs on the back
side, a symmetrical (XLR) and an asymmetrical
(RCA). By using the included XLR to RCA adapter
an RCA-input can be created from the XLR input
socket. So the left and right channel can be brought
together to be used, for example, in a typical two-channel stereo system where
deep bass will be reproduced through a subwoofer. These are signal level
inputs. Please never feed these inputs with higher voltage than typically
delivered to an input of a power amplifier. If there is no special “SUB OUT”
on your preamplifier/decoder, it may be connected - as a last resort over a
Y-adapter – to the subwoofer via the “PRE OUT” to both of the inputs on the
subwoofer.
