LED Functions
Limit LED - When illuminated this indicates that the
system is approaching clipping. An occasional flicker of
the red LED on the loudest peaks is acceptable. If this LED
remains red for more than the duration of brief dynamic
peaks, or lights continuously then the system is being
overdriven. If the red LED illuminates excessively, reduce
the output level of the mixer, or other source to the speaker.
Signal LED – The Green LED indicates that a useable
signal is present at the input.
Power LED – When AC mains is connected to the
speaker and the power switch is turned on, the blue lower
LED will illuminate.
Audio Connections
The signal input & link connectors are fully balanced.
When connecting a balanced signal be sure to wire to the
following standard:
SIGNAL XLR CONNECTOR
Hot (+) Pin 2
Cold (-) Pin 3
Shield (GND) Pin 1
In a standard balanced interconnection there are two signal
conductors and a shield. The shield is normally referenced
to ground at one or both ends. Many times the shield is
lifted at one end, usually at the input to eliminate “ground
loops” or noise. This should be done only as a last resort;
although it will reduce hum, the shields can act as radio
antennas and pick up radio frequency interference from
the environment.
Multiple enclosures may be driven from a single audio
source; simply plug the signal source output into the first
XLR input socket, and patch that speaker’s XLR link to the
next speaker’s XLR input socket.
Gain Structure and Limiting
The VSXNET gain structure is designed to allow a low-
level source device to drive the loudspeaker to full output.
Maximum specified SPL will be achieved with a 4 dBu
input signal. There is sufficient headroom in the signal path
to accommodate input levels of 10 or even 20 dBu, with
high quality compression engaged as needed to maintain
sonic integrity without clipping.
Equalisation
The VSXNET loudspeaker requires no equalisation or
correction to overcome system limitations; equalisation
is necessary only to compensate for difficult acoustic
environments.
Rigging and Safety Procedures
The installation of Tannoy Professional loudspeakers using
the dedicated hardware should carried out only by fully
qualified installers, in accordance with all the required
safety codes and standards that are applied at the place
of installation.
WARNING: As the legal requirements for flying change
from country to country, please consult your local safety
standards office before installing any product. We also
