DPA4000 POWER AMPLIFIER
The heart of the LAs15A is a powerful, light weight, highly efficient Class D
power amplifier module (2x2000W), with PFC switched mode power
supply, that delivers an impressive sonic punch with perfectly balanced,
rich and transparent sound at any volume. The integrated Networkable
DSP 24bit/96kHz provides 8 selectable memories (7 factory defined and 1
user defined) that can be accessed by an easy selector, located on the
module front panel or real time edited by a PC, using the supplied SOUND-
WARE software, via USB/RS485 remote control. This allows to easily
customize the sound program, for various applications.
With the SOUNDWARE software it is possible to edit each one of the 7
pre-loaded configurations and store it in the free memory. Editable
parameters are for example: input equalization, input delay, input
High-pass and Low-pass filters, Subwoofer Level/Delay/Polarity, Satellite
Level/Delay/Polarity. A total of 255 units can be controlled simultaneously
by the software.
