4.4 Splitting a Zone
A separately available product called a
Zone Splitter may be used to add a second
pair of speakers to a zone. This enables a
zone to be “split” between two rooms or
areas. Control of both the “prime” zone
and the sub-zone is via the DMS - see
Section 6.46 Zone Splitter Control for
further details.
The Zone Splitter is essentially a remote
control speaker switch and as such,
requires the speaker output and data cables
to be connected to it. The two pairs of
speakers and the data wires from the prime
and sub-zone are also connected to the
Zone Splitter - see diagrams below.
The sub-zone may be fitted with either a
KMS, a DMS or both. It could also be fitted
with a QED Speaker Volume Control (in line
with the speaker cables) or indeed, no
control at all. All speaker selections,
however, can only be carried out from the
prime zone DMS.
The following points must be considered
when installing a Zone Splitter system:
• Important: The Zone Splitter is a parallel
speaker switching device. Therefore,
speakers with 8 ohm impedance MUST be
used in both areas A and B.
Two-way Quick-Fit speaker plugs (supplied)
must be used for speaker wiring and I.D.C.
plugs (supplied) for data wiring. These are
identical to those used on the S4.3
Controller - see sections 4.12 and 4.14.
• The Zone Splitter can be installed
anywhere but you must be able to connect
the cables from each pair of speakers
directly to the unit.
• There is no requirement for a power
connection to the Zone Splitter; the supply
is taken from the data cable.
Control of the Zone Splitter is described in
Section 6.46.
