2. INSTALLATION

The DPM3003 is conceived as a piggyback module for speaker cabinets, in order to build self-
powered, 3-way units.
The cooling system is a back-to-back design, forced ventilation with variable speed fan. However,
it is advisable not to expose the unit to extreme temperatures as well as ensure a dry and dust-free
operating environment.
It is important not to place the module next to electrical noise sources such as transformers,
voltage dimmers, motors, etc. or their mains supply cables. The metal cover of the device should never
be removed under any circumstance for that same reason.
The DPM3003 operates with alternate current (AC) between 100 and 264V at 47 to 63Hz. This
device features an oversized power supply which adapts itself to any mains voltage around the world,
without the need of manual adjustment.
It is always advisable to follow this power up sequence: signal sources, mixing unit, processor
and, finally, power amplifiers. The power down sequence must follow exactly a reverse order. By closely
following this sequences, all peaks or transients produced by switching on and off devices do not affect
the next devices in the chain and, of course, never reach the loudspeakers, which are extremely
sensitive about this.

3. INTRODUCTION

3.1. About DPM3003

The DPM3003 includes an one input, three outputs .amic DSP processor and three class D
amplifiers (see chapter 7 for full characteristics).
This .amic card is a powerful and fully programmable digital signal processor with one high
quality audio input channel and three output channels (each one routed to the input of one out of the
three amplifiers), as well as a USB computer link.
The available connections on the surface of the module are
 One XLR audio input
 One Stack (link) audio output
 Two PowerCon® sockets: connect one of them to the AC mains and use the other one to
link and deliver AC voltage to the next DPM3003 used in the chain (usually a line array
set of cabinets).
 Two AMP MATE-N-LOK male sockets for the amplifier outputs, placed on the back panel.
There are also 7 LED indicators available:
 ON
 STANDBY / THERMAL PROTECTION (it will be lit during stand by mode or if a thermal
protection is activated while the module is in the ON mode)
 PROTECT (protection activated)
 CLIP HIGH, CLIP MID, CLIP LOW (clipping warning for each amplifier)
 SIGNAL PRESENT (an audio signal is detected at the input stage)
