7. Connecting the remote input
The remote input (REM) has to be connected to
the radio remote output. This is only activated
if the head unit / car radio is switched on. Thus
the amplier is switched on and o󰀨 together with
the head unit / car radio.
We do not recommend controlling the remote
input via the ignition switch to avoid pop noise
during turn on / o󰀨.
If an additional digital signal processor (DSP)
is installed in the signal path between the radio
and the amplier, the remote output of the DSP
must be used to turn on the P ONE.
8. Connecting the loudspeaker outputs
The loudspeaker outputs can be connected
directly to the wires of the loudspeakers. Never
connect any of the loudspeaker cables to the
chassis ground as this will damage your ampli-
er and your speakers.
The positive terminal is indicated on most
speakers. The impedance must not be less
than 1 Ohm (2 Ohms in TwinPower Link mode),
otherwise the amplier protection will be acti-
vated. Examples for speaker congurations can
be found on page 19 et sqq.
Start-Stop capability
The switched power supply of the HELIX P ONE as-
sures operation even if the battery’s voltage drops
down to 6 Volts during engine crank.
High-Resolution audio
The extremely broadband audio bandwidth of the
amplier ensures a lossless audio reproduction of
High-Resolution audio content to provide the best
possible sound in studio quality.
