GENERAL DESCRIPTION

 

 

 

 

 

 

 

 

 

 

Atlas Sound’s UHT and UKT Series are 8" diameter single and dual voice coil loudspeakers

 

 

 

 

equipped with dual (whizzer) cone and 10 oz. ceramic magnet to deliver extended frequency

 

 

 

 

response with high intelligibility and minimal distortion. Cost-effective units are complete with

 

 

 

 

fire-retardant moisture-proof cones, factory-mounted transformer, 6" color-coded leads, and a

 

 

 

 

wide selection of architecturally pleasing baffles. UHT Series loudspeakers have a 1" dia. voice

 

 

 

 

coil, choice of 70.7 or 25-volt transformer, and DC blocking capacitor for line supervision appli-

 

 

 

 

cations. UKT Series loudspeakers are equipped with two 1" dia. voice coils, two transformers

 

 

 

 

(specify 70.7 or 25 volts), and a DC blocking capacitor. To comply with UL requirements, loud-

 

 

 

 

speaker packages must be used with UL-approved enclosures (refer to back page for baffle/

 

 

 

 

enclosure information and to SL6-1424 “Enclosures for UL Listed Loudspeakers”).

UHT Series, UKT Series specifications

Atlas Sound is renowned for its high-quality audio solutions, and its UKT and UHT series of amplifiers are no exception. Both series are designed to meet the diverse needs of commercial audio applications, providing reliable performance and robust features for various environments.

The UKT Series amplifiers are specifically engineered for lightweight installations and portable applications. These amplifiers provide a perfect balance of power, efficiency, and flexibility. With a range of output options, the UKT series offers models from 70V/100V operation to low-impedance outputs, making them suitable for both distributed and local sound reinforcement systems.

One of the standout features of the UKT series is its digital signal processing (DSP) capabilities. This technology allows integrators to customize their audio output, ensuring optimal performance in any setting. The DSP included in UKT amplifiers also facilitates limiter functions, equalization, and delay settings, providing users with a comprehensive suite of tools for precise audio control.

On the other hand, the UHT Series is designed for ultra-high efficiency, utilizing Class D technology to minimize energy consumption while maximizing output. The UHT amplifiers are built for durability, with rugged chassis designed for frequent use in commercial environments. This series not only provides exceptional sound quality but also features a lightweight design that makes installation and transportation effortless.

Both the UKT and UHT series offer advanced protection features, including thermal overload protection, short circuit protection, and signal clipping prevention, which safeguard the amplifiers during operation. The UHT series also includes an intuitive front-panel user interface with LED indicators for straightforward monitoring of performance levels and error statuses.

Connectivity is another area where both series shine. They incorporate multiple input options, including XLR and phono connectors, allowing for easy integration with various audio sources. These amplifiers are versatile enough to handle background music, speech reinforcement, or even full-range live sound reinforcement applications.

In conclusion, Atlas Sound's UKT and UHT series amplifiers represent a fusion of modern technology and reliable performance, making them ideal for users seeking quality sound reinforcement solutions in commercial settings. Their efficient designs, advanced DSP capabilities, and robust protection features ensure that audio professionals can deliver exceptional sound experiences in any venue.
