Proel ASO25 PRL

The ASO25 Active System Optimizer is developed by Proel to be installed in TFLV/TFL and TPRMARKII sound systems, to optimize the signal and obtain excellent levels of performance. ASO25 addresses the signal to be sent separately to the amplifier section of the high frequencies and to the amplifier section of the low frequencies. ASO25 is provided with two input channels, two outputs for the high-end, two outputs for the low-end, a further Mono Low output. The built-in 24/ dB oct crossover is Linkwitz-Riley type with frequency set at 125Hz. ASO25 is also equipped with a subsonic filter and an adjustable limiter. By intervening in the internal part of the device, it is possible to modify the frequency cut (80Hz, 125Hz, 160Hz) and insert delay lines (0, 300µs, 600µs). With an appropriate complementary board (on request) it is possible to add personalized parametric filters. Moreover, further internal modification permits ¿on air¿ shelving tone adjustment at 10kHz.
