Integra Ships 9-Channel THX-Certified Home Theater Amp: DTA-70.1

High-end home theater manufacturer Integra is now shipping what is believed to be the company’s and industry’s first high-performance nine-channel home theater power amplifier. The DTA-70.1 9-channel home theater amplifier has received the highest THX-Ultra2 certification and is rated for 150 watts per channel into 8ohms.

Designed to operate in conjunction with Integra’s DHC-80.1 9.2-channel AV processor for theater systems that use the new height or stereo-wide channels for enhanced three-dimensional ambience, or any other brand of pre-processors, the amplifier is also a highly versatile companion to seven-channel preamps such as the Integra DHC-40.1 with the extra channels dedicated to additional zones or for bi-amplified connections that double the power available to the main stereo loudspeakers.

The unit, priced at an MSRP of $1,800 is placed perfectly for users looking to get into the expanding audio world of the latest formats or to mate their systems with the new, HDMI 1.4, 3D-compatible devices at a reasonable price for such high-end level gear.

Technical specifications that the DTA-70.1 features are an all-analog discrete-component power amplifier with a massive power supply and professional-style balance line inputs, identical symmetric circuit layouts, configured in a push-pull topology utilizing high-performance three-stage inverted Darlington circuitry and powerful custom-designed output transistors on each channel, and, as with all Integra amplifiers and receivers, it uses the company’s WRAT (wide range amplifier technology) with low negative feedback, closed ground-loop circuits, and HICC (high instantaneous-current capability) to achieve an extended frequency range, low noise, and high dynamics.

Inputs are gold-plated XLR and machined solid brass RCA for each channel and the color-coded speaker outputs use gold-plated banana-plug-compatible transparent binding posts. It has a 12-volt trigger input for remote turn on and off capabilities, and an automatic power-down capability.

The Integra DTA-70.1 is available now at an SRP of $1,800.
