Amplifier claims new standards for sound quality
In launching the Acoustar ZXCW8100 two-channel digital audio amplifier controller, Zetex claims to have created the world's first 32bit end-to-end digital audio amplifier solution.
Power devices qualify for automotive duties
Monitors, regulators and references meet the requirements of AEC-Q100 Grade 1 for operation in automotive environments at temperatures up to 125C.
Rectifier controller makes MOSFETs behave
Zero point detector driver allows designers to replace lossy Schottky diodes with surface mount MOSFETs for improved efficiency in power supply designs.
The company had been researching potential digital amplifier designs for many years, but until it evaluated the Zetex Acoustar devices last autumn it had been unable to identify a sufficiently developed control technology to realise the level of performance its engineers were demanding.
Since then the two companies have been working together to develop and refine the technology.
Commented Neil Sinclair, President of Theta Digital: "Zetex is the first engineering team to bring us the tools we need to produce a truly audiophile-calibre product".
"We performed a series of listening tests, and no other product came close".
"Zetex has provided us with an amazing toolkit - not an amp-in-a-box - to which we have applied our knowledge and expertise and achieved a Theta product we're all proud of".
The Virtu Power DAC is a seven channel 150W full digital power amplifier developed on the strengths of the Zetex Acoustar processing technology.
The full 32bit datapath, high 1MHz modulation frequency and ZTA digital filter combine to form the foundation for Theta's development of this outstanding amplifier.
