2. Mono/LFE line level input - RCA Phono socket
For mono applications, such as the subwoofer or LFE
output from a surround processor, use just one of the
line input sockets on the subwoofer. It does not matter
whether you use left or right.
Use appropriate high quality interconnect cables.

3. Trig 1 – 3.5mm mini-jack socket
This is a 12V trigger that may be used to switch the
PV1D between the on and standby states in step with
a master device, such as a surround processor, stereo
pre-amplifier or integrated amplifier that provides a
suitable trigger signal.
4. Trig 2 – 3.5mm mini-jack socket
This is a 12V trigger that may be used to switch
between two nominated presets. It would most usually
be connected to a trigger out signal on a processor
related to the selected source device.
5. RS-232 interface – 3.5mm mini-jack socket
This socket has two purposes. First, it enables
communication to a computer (most conveniently a
laptop) running the PV1D SubApp™ setup program.
A special 5m long USB to 3.5mm mini-jack cable is
supplied, which allows the user to sit at the normal
listening position when making adjustments.
Secondly, it enables control of the subwoofer by a
home automation system communicating by RS-232
protocol. See Section 7 for more.

6. Mini USB socket
From time to time it may be necessary to update the
subwoofer's internal software (firmware). This is done
from a computer running the updater program and a
USB to mini USB cable is required. This cable is not
supplied with the product, but may be purchased from
a computer store and is commonly used to connect
a digital camera. Check for updates on the PV1D
support page of our web site.
7. Power input – Polarised IEC C8 socket
The power cord supplied with the product will vary
according to region. A matching polarised IEC C7
plug is only supplied on North American power cords
commensurate with that region's polarised wall outlets.
In other regions, the power cable is supplied with a
non-polarised IEC C7 plug (popularly known as a figure
of 8), which mates with the socket but does not have
a flat side.
