Ave Stuttgart – Ascolto AH1635

Description:

The digitally controlled line arrays Ascolto® are equipped with high-quality 3,5” neodymium loudspeakers, capable to spread perfectly voice as well as sound instruments. They can handle higher power applications, delivering great tone at any volume levels. Each Ascolto® digital line array contains a set of custom-designed, fully-programmable 135-MHz, 48-bit DSPs where high precision 76-bit accumulators ensure the bit resolution for a total quality in digital audio processing such as beam filtering and audio equalization.
The Ascolto AH1635 is unique for its acoustic directivity, extremely selective and capable of reaching deep space. The Ascolto AH1635 is particularly suitable to ensure an extended coverage in large environments, where it needs simultaneously a very incisive beam and a bright tone.

Ascolto AH1635

enhances the quality of the sound;

improves environment with acoustically difficult characteristics;

focuses the sound energy directly to the public, minimizing the effects of the sound
reflections of the ceiling and the side walls;

fulfills all aesthetic and architectural requirements;

distributes capably audio in cathedrals, churches, mosques, theaters, auditoriums, airports,
railway stations and in general everywhere it is necessary acoustic precision and reliability.

The Ascolto AH1635 possesses the innovative Anti Reverberation System ARS®, capable of increasing the voice intelligibility in reverberant environments. ARS conveys uniformly acoustic energy on the lower part of the audio beam and reduce drastically the audio emission upwards, attenuating significantly the acoustic reflections related to ceilings.

AVE Line Array User Control® is a sophisticated software application that uses a complex proprietary algorithm to calculate accurately SPL distribution of Ascolto® Digital Line Arrays from their EASE® models. It allows the user to select the appropriate dispersion pattern and transfer aiming and filtering parameters to the digital line array through the dedicated network.

The AVE IRC Infrared Remote Control lets you control the configuration settings even if a host computer is not available.

The AH1635 is optionally available with Dante card. Thus the AH1635 can be integrated in an existing speaker system or in a Dante network.
