Description:

The digitally stereable column speaker Ascolto LH3225 is particularly suitable to ensure an extended coverage in large environments, such as auditoriums, churches with long aisles, cathedrals, basilicas and in general where it needs simultaneously a very incisive beam and a bright tone, capable to transmit perfectly voice as well as music.

The multibeam DSP filtering technology steers the vertical radiation patterns, matching the desired listening pattern, making column speaker Ascolto LH3225 high directive and featuring the main propagation lobes less dependent on the frequency.

Key features

Multi Beams Forming up-to 5 independent audio beams.
Vertical tilting / broading control of audio beams with AVE Line Array User Control Software.
Anti-Reverberation System ARS to increase the speech intelligibility index STI in reverberant environments.
4 DSP units at 145 MHz - 48 bit to process 32 audio channels.
32 x 2.5", full range neodymium woofer.
32 x 50 Wmax class-D audio amplifiers with high efficiency (90%) for respect to energy consumption.
900W high-reliable power supply with universal mains input (90-264 VAC) and compliance to IEC/EN 60601-1-2.
Multiple audio inputs including: Line, 100 V, (optional) DANTE input.
Delay control up-to 50 m.
User Equalizer with highpass, lowpass, shelving and PEQ filters.
Music Adaptive Equalizer for the best graceful musical listening.
Ready for external media control such as Crestron, AMX, ect.
Low-resonance extruded case entirely in aluminium for lightness and strength.
