CONNECTIONS

USB Data Link

The speaker DVA M2M is equipped with a USB "Service" connector, useful for the firmware update

of the module or to download speaker operation data.

Connecting to the mains supply

Each active speaker features its own power cable. Connection is done by a Neutrik POWER

CON® (Blue) model which permits easy and fast connection to the speaker as well as being an

excellent locking system.

The POWER CON connector acts as the disconnecting device for the power supply and must be

easily accessible after installation and during use of the speaker

The active speaker must be connected to a power supply able to deliver the maximum required

power.

Main power supply linking

On the rear of the speaker, a Neutrik POWER CON® connector (Grey) offers linking the mains

power supply.

This socket links the power supply to another speaker, thereby reducing the direct connections to

the mains. Maximum amplifier input power is shown on the amplifier panel.

The maximum number of speakers connected to the LINK OUT connector varies depending on the

voltage of power supply used and the type of connected speaker to this socket. Do not exceed in

any case the maximum current / power specified in the data on the panel. This failure can cause

overheating and damage to the products.
