Next Audiocom A504 DSP

The A504DSP combines a lightweight 4 x 500 W (2 x 1000 W) amplifier with a powerful
a DSP processor that can be configured to perform a wide range of tasks,
without the need for additional hardware to support a wide range
loudspeaker systems. Tight integration of processing and amplification allows
the DSP processor to monitor and better adapt to the amplifier's behavior,
making the processing dynamics much more accurate and effective than this
typically achieved with separate components

Maximum flexibility

A504DSP flexibly distributes the total amplifier power in various combinations to four, three or two outputs for control, for example: four full-range speakers or subwoofers, a high-power subwoofer + two full-range speakers, a high-power subwoofer + a bi-amplified speaker or a full-range speaker with high power + high power subwoofer

 

Designed for professional use, XLR Chassis connectors are manufactured by Neutrik

 Versatile use 

The A504DSP is a cost-effective power amplifier that can be used in both...
 route and during installation. 

 

Advanced DSP processor 

Built-in advanced DSP engine, controlled by the built-in OLED screen
 with encoder or via PC, with input/output routing, filters
 high-pass and low-pass parametric EQ filters,  
compressors/limiters, noise gates and equalization delays. 












 Integrated DSP processor

 Integrated DSP controlled by the built-in OLED screen
 encoder eliminates the need for external speaker processors.
 Everything you need to fine-tune the sound of any speaker is here. 








 Unique features 





 
Ultra thin design

 The ultra-slim design saves space while maintaining the elegant look you need. 




 Minimum impedance 4Ω 
To increase the number of speakers connected to a single amplifier channel, you can reduce the amplifier resistance to 4 Ω 



 100V Line Output
 Use this amplifier to flexibly power medium to large 100V line array speaker system setups

 

 Matrix
 The I/O matrix allows the user to easily route each input audio signal to the desired output port.

 DSP

 Integrated digital signal processor (DSP) offers the user the ability to easily equalize the sound and adapt it to the needs of the site/installation 



 Dedicated presets 

The integrated DSP allows you to have dedicated presets for different situations. You just need to choose which one is most convenient for your application.
