2JANE VX Series manual Bi-Amp Operation, Rigging and Safety Procedures

Bi-Amp Operation

The VX 12HP, VX 12Q, VX 12.2Q, VX 15HP, VX 15Q only may be internally reconfigured for bi-amp operation to supply greater system headroom. Reconfiguration is as follows:

First, remove the rear termination panel. It is secured with 2.5 mm hex drive screws.

In passive (default) mode, the internal wiring is as shown in Fig. 1, with the full-range signal routed through the internal crossover and divided into separate LF and HF signals using a 4-pole connector.

Fig. 1.

For bi-amp operation, reconfigure the internal wiring as shown in Fig 2. The two-wire connector leading to the crossover is disconnected. The four-wire connector from the speakers now bypasses the crossover and instead connects directly to the speakON inputs, replacing the connector that previously led to the crossover.

Fig. 2.

For bi-amp operation, the speakON connectors coming from the amplifier(s) must be wired as follows:

speakON		Amplifier
1	+	LF +
1	-	LF –
2	+	HF +
2	-	HF –

Rigging and Safety Procedures

WARNING: As the legal requirements for flying/suspending/hanging/ rigging loudspeakers change from country to country, please consult your local safety standards office before installing any product. We also recommend that you thoroughly check any laws and bylaws prior to installation.
