12 AUDIO CONNECTIONS
The signal input & link connectors are fully balanced.
When connecting a balanced signal be sure to wire to the following standard:-
Hot (+), Cold (-), Shield (GND)
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. The problem with this approach is that while it may reduce hum, the shields act as radio antennas and pickup
radio frequency interference from the environment.
Multiple enclosures may be driven from a single audio source; simply connect the signal source output into the first input
socket, and patch that speakers link to the next speakers input & so on.
13 NETWORK CONNECTIONS
(VNET in & Link)
Interconnection between the network computer and the speakers is very straight forward, using twisted pair cable and
simple connectors. The USB to VNET (RS485) interface operates on a shared bus so that a single computer can control
any QFlex loudspeaker on the bus, and the computer may gather status information from any device on the bus. Each
module contains a unique address so that no user input will be required to configure network nodes.
It is only data that is carried over the network to control setup functions & ongoing system diagnostics, therefore if a
network fault occurs, audio can still be delivered. This alleviates the problem of total system failure through a single
system controller going down. As each loudspeaker controls it own DSP functions any unforeseen failure would be
isolated to only that particular node.
Use of the Tannoy USB to VNET interface (Part No. 8001 4150)
is highly recommended. The interface and QFlex loudspeakers
use RJ45 connector’s throught, so no need to use non standard
connections when using 3
rd
party interfaces.
