Audient ASP-231 Graphic Equaliser

 

ASP-231 Dual channel Graphic Equaliser

Graphic Equalisers have become an indispensable tool for system alignment and optimisation. But while the demands of contemporary users, performers and audiences have pushed forward live sound technologies in many areas, the performance and functionality of 'graphic equalisers' has remained largely unchanged for the last 15 years. Scores of manufacturers have entered the market with 'me-too' products giving little thought to whether the old 'recipe' was still valid.

The ASP231 Graphic Processor has been designed from a fresh perspective.

The performance design targets were set after careful research and analysis of current market expectations and demands.


31 bands

  • MFBP (Multiple Feedback Bandpass) filter topology for enhanced sonic performance.
  • Advanced High CMRR balanced input.
  • High current output topology.
  • Automatic power fail bypass.
  • XLR and Klippon/Phoenix I/O terminations.
  • Optional transformer balancing.
  • Optional security cover.
