operation Audio ACTIVE
The amplifier module reduces the volume, in
steps of 0.1 dBm up to a maximum of 6dBm,
as the temperature rises above the safety
threshold.

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.
