There is no sound

Power off. Equipment setting is wrong.

Assure that power is applied to all equipment in system. Check

 

Volume set too low.

that routing (input/output) controls are set correctly. Check that

 

 

volume level is above minimum.

 

 

 

 

Loose connection.

Check system from start to fi nish for crossed wires, loose

 

 

connection, etc. On the AH location check for correct connection.

 

 

 

Low sound level

Setting/volume control is set too low.

Check volume levels or amplifi ers and related equipment

 

Connection is shorted or bad.

(equalizer). Check that connections aren't partially shorted/

 

 

corroded.

 

 

 

Sound cuts in and out

System overload/oscillation intermittent connection.

Check for overload condition or bad connection.

 

 

 

Distortion at increased levels

Amplifi er/speaker overdriven.

Check that power to speaker isn't over limits. Check that amplifi er

 

 

isn't overdriven. Reduce power to amplifi er slightly.

 

 

 

Speaker makes "buzzing" noise

Atlas Sound is a renowned name in the world of professional audio solutions, and their line of speakers, including the AH94-12ST, AH94-8ST, AH66-8ST, AH99-8ST, and AH66-12ST, reflects their commitment to quality and innovation. These speakers are designed for a variety of applications, including installations in schools, auditoriums, and various public spaces, where clarity of sound and robustness are essential.

The AH94-12ST and AH94-8ST are part of Atlas Sound's advanced loudspeaker series, featuring weather-resistant construction ideal for both indoor and outdoor use. The AH94-12ST boasts a 12-inch woofer and a titanium dome high-frequency driver, providing impressive sound transmission over large areas. This model is well-equipped for large venues, ensuring rich bass and clear highs, perfect for music playback and speech intelligibility. In contrast, the AH94-8ST, with its 8-inch woofer, offers a slightly lighter option without sacrificing sound quality, making it suitable for smaller rooms where full-range sound is still required.

The AH66-8ST and AH66-12ST models enhance versatility with their dual-impedance configurations, allowing easy integration into existing audio systems. The AH66-12ST features a larger woofer that delivers deeper bass response, ensuring that music and speech are delivered with full fidelity. The AH66-8ST, being more compact, serves well in applications where space is a premium, yet still offers the same high-quality sound performance.

Lastly, the AH99-8ST stands out with its wide coverage pattern and increased power handling capabilities, designed to distribute sound evenly across larger areas. This makes it an ideal choice for installations where wide dispersion and volume control are key, such as gymnasiums or large assembly halls.

All these speakers incorporate advanced technologies including neodymium magnets, mounting options for flexible installation, and durable enclosures designed to withstand the rigors of professional use. They also come equipped with high-efficiency voice coils, ensuring high output while maintaining minimal distortion.

In summary, the Atlas Sound AH94, AH66, and AH99 series speakers are essential tools for professional audio applications, providing superior sound quality, innovative features, and reliable performance for various settings. Whether used individually or as part of a larger sound system, these speakers are designed to meet the diverse needs of today's audio professionals.
