Wiring the connectors
Low Impedance (8 ohm) Mode Fig.1 VLS 7 & VLS 15
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
A right angled water tight cable gland is supplied
with the VLS 7 and 15 for use in outdoor
applications (Fig.1). The VLS 30 has an input
panel cover with rubber wiring grommet for use
in outdoor applications (Fig.2). Before making
connections, pass the wire(s) through the cable
grand/rubber grommet. The input panel cover
is secured to the cabinet using the four screws
already inserted around the input.
