Object and Liquid Entry
The apparatus must be placed in inappropriate position. Care should be taken so that objects do not
fall and liquids are not spilled into the enclosure through cooling grid with consequent electrical
danger.
Ventilation
The appliance should be situated so that its location or position does not interfere with its proper
ventilation. Do not block or cover any openings of the grid ventilation or heatsink. Install the apparatus
at a distance that ensures a good ventilation between devices.
Heat
Do not install the appliance near any source of heat.
Accessories and installation
For a safe installation, do not make any holes in the external chassis for the application of additional
brackets. In case of particular installations not described in this manual, contact technical service for
accessories specified by the manufacturer.
Follow the instructions
All operations and instructions in this user manual should be followed for a correct operation and
function of appliance. Pay attention in particular to:
- Never force the control elements (switches, controls, etc.).
- Do not force the amplifier to work in overload for extended periods of time.
Cleaning
Clean only with a dry cloth. Do not use solvents, alcohol, benzene or volatile substances for cleaning
the exterior parts.
CONNECTION
CAUTION
- For connecting the appliance, use only qualified and experienced personnel having sufficient
technical knowledge or specific instructions for making the connections correctly and thus
preventing electrical dangers.
- To prevent the risk of electrical shock, the appliance must only be supplied from the mains after
all connections have been completed.
- Before powering up the appliance, it is advisable to re-check all the connections.
- The entire sound system must be designed and installed in compliance with the current
standards and regulations regarding electrical systems.
SUGGESTIONS
CAUTION
To prevent inductive phenomena from giving rise to hum or disturbance which would jeopardize
efficient appliance operation, the cables that transmit microphone signals or line level signals (e.g. 0
dB/V) must be screened and should not be run in the vicinity of:
1) Equipment that produces strong magnetic fields (e.g. large power supply transformers)
2) Electrical energy conductors
3) Lines that supply speakers.

DESCRIPTION
The bi-amped DVX DM stage monitor speaker series is equipped with DIGIPRO series
class D amplifier. This high-efficiency amplifier delivers high output power in a compact
size and low weight. Thanks to its high efficiency the cooling of the amplifier module is
obtained statically, thus avoiding the use of a external fans.
The power supply circuits of the DIGIPRO amplifier has been conceived to work in full-
range mode; thanks to the SMPS (Switched-Mode Power Supplies) technology with PFC
(Power Factor Correction) the operation with supply voltages between 100 Vac and
240Vac is guaranteed by ensuring the same sound performances even with floating and
non-stabilized power supply systems.
DVX DM 28
