The digital steering column Ascolto FF0870 is particularly suitable to ensure an extended coverage in large environments, such as churches with long aisles, cathedrals, basilicas and in general where it needs simultaneously a very incisive beam and a bright tone.
FF0870 performs 8-channel DSP beam filtering to steer the vertical radiation pattern, matching the desired listening pattern, making column high directive and featuring main propagation lobe less dependent on the frequency.
FF0870 is equipped with 8 high quality, waterproof, coaxial loudspeakers, each one mounting 4” neodymium woofer + 1’’ dome tweeter, capable to transmit perfectly voice as well as music.
FF0870 uses 8 x 70 Wrms class-D audio amplifiers with excellent THD+N and high efficiency (90%). They are completely pop free and protected against short-circuit and thermal over-load.
FF0870 mounts high-reliable, switching power supply with universal input (90 – 264 VAC) to ensure the necessary "power" demand (360 W continuous / 430 W peak) to the amplifier units.
Beside the primary analog line input, FF0870 has an auxiliary audio input at 100 V level or a built-in Dante input (choose respectively FF0870 - 100 V or FF0870 - Dante version). Thus, it can be integrated and connected into an existing speaker line or into a Dante network.
FF0870 setup comes easy throughout the AVE Line Array User Control PC software, via RS485 connection.
AVE Line Array User Control includes:
FF0870 cabinet is aluminum extrusion and powder coated with desired RAL color.
All digital steering column loudspeakers Ascolto are designed and manufactured in Germany.
