Cables, Crossovers and Connections
For best results, connect your loudspeakers with purpose-designed loudspeaker
cable. The cables to both loudspeakers should be of equal lengths and be of a
gauge sucient to drive the speakers comfortably without any loss of power in the
bass at high volumes.
We recommend a minimum wire diameter of 14 AWG. If you are in any doubt,
you should connect the loudspeakers before you connect the amplier. If you are
replacing a existing pair of loudspeakers, we suggest you de-wire the amplier rst.
There are two crossover networks in the P-38F, P-37F, P-17B and P-27C. One panel
is a dedicated bass network. The second panel is a network for the midrange and
treble units . The networks terminate in a custom designed bi-wire terminal panel located on the lower back
panel of the loudspeaker. As the low and high frequency elements can be separately connected, two types of
wiring are possible: standard wiring and bi-wiring.
The terminal panel accepts a wide variety of connectors, including spade lugs, pins or bare
wire. If you have no preference, your dealer can advise you as to appropriate connectors.
The instructions in this user guide relate to bare wire. If you use alternative connectors,
consult your dealer or the hardware supplier’s literature.
Standard loudspeaker cable is comprised of two conductors, with one core having a ridge
or stripe. We suggest you connect the striped conductor to the Positive (RED) terminal in all
cases. This will ensure that the loudspeakers are properly connected and in phase.
Split the cable to a depth of 1½”. Strip ½” of insulation. If the wire is stranded, lightly twist
the ends together to ensure no stray ends of cable can short adjacent terminals.
Connecting a Terminal
Partially unscrew the terminal.
1: In the base of the terminal, there is a hole. Insert the bare end of the wire into
the hole.
2: Tighten each connector hand tight. After connecting all the terminals, check
that there are no stray strands of bare wire that can reach across and short out
adjacent terminals.
3: When you are sure that all the connections are correct, insert the Allen key into
the socket in each terminal head and tighten fully to secure them. DO NOT
over-tighten the terminals, or you may damage them. (An Allen key (hex
wrench) is provided in the accessories carton.)
Positioning Center and Surrounds
Center Channel Positioning
The P-27C is a dedicated center channel speaker that should be placed as close as possible to the center of
your video display. In installations with large projection or display screens, the speaker is traditionally placed
immediately below the screen and positioned with an upward tilt. (See the section on “Fitting the Spikes” for
more information.) The degree of tilt will depend on many factors, including the size of your video screen and
the distance to your listening/viewing position. The center channel should also be placed equidistant from the
left and right main channel speakers.
Surround Channel Positioning
The P-27S is a dedicated surround channel
speaker that is used to provide sound for
the rear eects channel of a digital sur-
round system, or as additional speakers
in a multi-channel music conguration.
The placement of the speakers will vary
depending upon the installation and
the type of system conguration. The
P-27S is designed to be wall-mounted
and includes mounting provisions on the
back. Make sure you use an appropriate
size screw head and that it is anchored
securely to a wall stud or wall anchor with
suitable weight-bearing capacity. Never
use the wall bracket for mounting the
P-27S to the ceiling.
For 5.1 systems, the surround speak-
ers are traditionally placed directly at or
just slightly behind the sides of the listening / viewing position. They should be placed approximately 4-5ft
(1.2-1.5m) above the oor. This distance can vary depending on the conguration of your room.
For 7.1 systems, the left and right side surrounds would be positioned as described above for a 5.1 system.
Two additional speakers would be added on the back wall of the room and should be placed relatively close
together. In most cases, you should position them from 12”-48” (1-1.2m) apart. They should be placed at the
same height as the side surrounds.
