DESCRIPTION

ATEÏS introduces a new generation range of steerable line-arrays, the ORBIT, that have an Omni-directional and steerable radiation pattern, fully redesigned to meet the highest architectural demands and equipped to handle current and upcoming requirements for the Voice-Alarm industry, Commercial Audio and Pro-Sound.

FEATURES

• Specially designed for high quality speech and background music applications in reverberant acoustic environments where it is difficult to meet contractual speech intelligibility requirements.
• Tightly controlled beam, up to 3 degrees, which can be shaped in nine steps to meet each specific application or environment.
• A-symmetrical and Symmetrical arrangement by means of software control.
• Integrated DSP control with 7 band parametric EQ, noise gate,  delay rooms, peak limiter, VOX-control on priority input and level raising microphone for ambient noise sensing.
• Adaptable ACOUSTIC center. Acoustic center can be freely moved over the array to match lobe shape with the listening area.
• Equipped for Voice evacuation applications.
• 24 VDC input for battery back-up, 20 kHz Input surveillance.    
• Internal HF carrier loudspeaker surveillance.
• Ambient noise sensor. Temperature sensor with frost protection.
• Battery surveillance. Fault report contacts.
• TCP/IP remote link and RS485 data bus for full detailed status report and PC based remote setup (up to 32 Messengers on the bus).
• EASE DLL & CATT DLL, for advanced room acoustic simulations.
• SPL stays within +/- 2 dB variation over a distance of at least 60 m.

Models:

• ORBIT M - 3 rows of 12 loudspeakers – 1003 mm 90 dB to 10 m circle
• ORBIT L - 3 rows of 18 loudspeakers – 1390 mm 90 dB to 15 m circle
