Description
Through both electronic and software optimisation, the new DELTA-AXF12 and AXF15 models now feature internal FIR filters using ‘DNA’ harvested from the flagship WLA active line array and monitors system development. This FIR filtering has brought independent control of magnitude and phase, more detailed equalisation and optimisation of frequency and power response. In the end….this results in highly improved system performance. The amplifiers have also been optimised, resulting in 800 W Continuous power.
Features
- Internal FIR signal processing
- Proven ‘DELTA Active’ reliability
- Practical ‘DELTA Active’ design
- Retro-fittable electronics
- Compatible with DELTA active subwoofers
- Increased Continuous Power. Now 800 Watts
