Tannoy VLS SERIES Quick Start Manual - page 4
Unpacking
Each Tannoy VLS Series loudspeaker is
carefully tested and inspected prior to
shipment. After unpacking, please inspect
for any exterior physical damage, and save
the carton and any relevant packaging
materials in case the loudspeaker again
requires packing and shipping. In the event
that damage has been sustained in transit,
please notify your dealer and the shipping
carrier immediately.
Connectors and cabling
VLS Series loudspeakers are connected to
the amplifier (or to other loudspeakers in
a 70/100 V system or series/parallel
configuration) using a pair of internally
paralleled barrier strip connectors.
All VLS Series models can be operated as
either an 8 ohm low impedance loudspeaker
or within a 70.7/100 V distributed system.
The operation mode is selectable via a single
switch located on the rear of the cabinet
(see below).
Operation in low impedance mode often
will require use of larger diameter cables than
are needed for a 70/100 V distributed system.
Please consult the full VLS Operation Manual
for recommended cable types for various
applications.
Wiring the Connectors
Low Impedance (8 ohm) Mode
If connecting directly to the amplifier in low
impedance mode, connect the positive (+)
conductor to a positive (+) barrier strip terminal
and the negative (-) conductor to a negative (-)
terminal. It is preferable to connect several
loudspeakers to one amplifier output in parallel,
series, or series/parallel configurations using
the other internally paralleled barrier strip
connector. For more information on this, please
consult the full VLS Series Operation Manual.
Constant voltage (70 V / 100 V) Mode
In constant voltage distributed systems, normally
a number of loudspeakers are connected in
parallel to a single amplifier output. Connect
the positive (+) conductor from the amplifier or
prior loudspeaker in the system to a positive
(+) barrier strip terminal and the negative (-)
conductor to a negative (-) terminal. The other
parallel barrier strip is available for connecting
additional loudspeakers.
Outdoor Applications
An input panel cover with rubber wiring
grommet is supplied for use in outdoor
applications. Before making connections,
pass the wire(s) through the rubber grommet.
The input panel cover is secured to the cabinet
using the four screws already inserted around
the input.
