Connecting The Amplifier To The Loudspeaker; Pin Designations - Community VERIS 2 Operation Manual

CONNECTING THE AMPLIFIER TO THE LOUDSPEAKER

All VERIS 2 Series loudspeakers are provided with two methods of connecting the amplifier to
the loudspeaker. One is an industry standard NL4 type locking connector, and the other is a
pressure-screw terminal strip. These two connectors are wired in parallel with each other, on
all models.
Figure 4: VERIS 2 Input Panel
The following figure is an example of a typical input panel used on VERIS 2
loudspeakers. A similar panel is used on all standard, low impedance VERIS 2 models.
The loudspeaker is intended to be connected directly to the amplifier.

PIN DESIGNATIONS

For all models the pin designation is as follows:
 NL4 Pin 1+ or the terminal screw labeled (+) connect to the positive (red) output
of the amplifier.
 NL4 Pin 1- or the terminal screw labeled (-) connect to the negative (black)
output of the amplifier.
Note that the NL4 and the terminal strip are wired in parallel, and that Pins 2+ and
2- on the NL4 connector are not utilized.
CAUTION: Be sure to carefully observe polarity when wiring your loudspeakers. If
one loudspeaker is wired with the opposite polarity from another loudspeaker, acoustic
cancellation will occur. The result will be less acoustic power output than if only one
loudspeaker were used by itself.

The following figure is an example of the input panel used on VERIS 2 loudspeakers
equipped with an optional autoformer. Such models are intended to be used in a 70V
or 100V "constant voltage distribution system."
