Proel AS025 2 Way Stereo Sub Mono Crossover XLR in/ XLR out, USED

Powers on, untested

The ASO25 Active System Optimizer is designed to take the performance of passive loudspeaker systems to the highest level.

The excellent construction ensures that the ASO25 optimally divides the signal to be sent to the amplification of the 'high' section from the signal that goes into the amplification of the 'bass' section. It has two input channels, two high output channels, two low output channels and an additional mono low output.

The crossover is of the Linkwitz-Riley 24dB / oct type with a cut-off frequency at 125Hz.

The ASO25 is also equipped with a subsonic filter and adjustable limiter. Acting inside the device, it is possible to vary the cut-off frequency (80Hz, 125Hz, 160Hz) and insert delay lines (0, 300µs, 600µs). With a special additional card (on request) it is possible to add customized parametric filters. Furthermore, always from the inside, it is possible to act on a shelving tone control at 10kHz 'on air'.
