7. Connecting the loudspeaker outputs
The loudspeaker outputs can be connect-
ed directly to the wires of the loudspeakers.
Never connect any of the loudspeaker cables
with the chassis ground as this will damage
your amplier and your speakers. Ensure that
the loudspeakers are correctly connected (in
phase), i.e. plus to plus and minus to minus.
Exchanging plus and minus causes a total
loss of bass reproduction. The plus pole is
indicated on most speakers. The impedance
must not be lower than 1 Ohm, otherwise the
amplier protection will be activated. Exam-
ples for speaker congurations can be found
on page 19 et sqq.
8. Optional: Activation / deactivation of the
internal subsonic lter
The P ONE MK2 is equipped with a switch-
able 21 Hz subsonic lter. The lter can be
activated or deactivated inside the device.
On: Subsonic lter activated (by default).
O: Subsonic lter deactivated. The subsonic
lter should only be deactivated if the am-
plier is driven by a digital signal proces-
sor (DSP) or DSP amplier. In addition,
a subsonic (highpass) lter with a cut-o
frequency of min. 20 Hz and a slope of
min. 36 dB/octave (Butterworth character-
istic) must be provided in the signal path
of the preconnected DSP / DSP amplier.
