6. Configuring a Surround Processor

The PV1D may be controlled by a home automation 
system running RS-232 protocol. A stereo 3.5mm 
mini-jack socket is provided on the underside of the 
PV1D. As this is not the standard RS-232 connection, 
the installer will need to make a custom cable with the 
following pin connections to the mini-jack plug:

Tip   

Transmit data (Tx)

Ring 

Receive data (Rx)

Sleeve 

Ground

The control codes may be downloaded from the PV1D 
support page of our web site.

Once set up the PV1D should require little adjustment. 
However, if it is moved within the listening room or if 
large items of furniture are introduced, its 

Gain

 and 

SysEQ

 may need adjustment. Please remember that 

the PV1D is capable of volume levels that have the 
potential to damage your and others’ hearing. If in any 
doubt reduce the volume. If the PV1D is overloaded, its 
standby indicator will flash red.

The performance of your PV1D may change subtly 
during the initial listening period. If it has been stored 
in a cold environment, the damping compounds and 
suspension materials of the drive units will take some 
time to recover their correct mechanical properties. 
The drive unit suspension will also loosen up during 
the first hours of use. The time taken for the speaker to 
achieve its intended performance will vary depending 
on previous storage conditions and how it is used. 
As a guide, allow up to a week for the temperature 
effects to stabilise and 15 hours of average use for 
the mechanical parts to attain their intended design 
characteristics.

You may wish to reassess settings once the subwoofer 
is fully run in.

The surround processor setup process involves setting 
a distance for each speaker and, if ‘small’ speakers 
are used, configuring the crossover that diverts very 
low bass to the subwoofer. The settings recommended 
in the processor instructions are generalised and not 
customised for the speakers actually used.

In order to optimise the system, please use the 
following settings in the processor:

Set the distance to the subwoofer 30cm (1 ft) greater 
than the actual measured distance.

For ‘large’ speakers, set the distance to that actually 
measured.

For ‘small’ speakers, always use the default Dolby 
Digital crossover configuration with the frequency set 
at 80Hz. Then, for each speaker listed, reduce the 
distance from that actually measured by the value in a 
look-up table.

So that the look-up table may be kept up to date, you 
can find it on the PV1D support page of our web sites.
