On Monday Apple introduced the eMac, a 17 inch CRT-based all in one design created specifically for the education market. Today
Tripath Technology Inc.
outlined its involvement in the eMac — Tripath developed the digital audio amplifier used in the new education-only system.
Tripath said that its TA2024 amplifier will be a standard feature on the new eMac, providing a “high-fidelity audio experience” for students using the new system.
The TA2024 Class-T 1-bit digital amplifier operates at 16W and up to 90 percent efficiency, according to Tripath. It’s integrated directly onto the eMac’s main board assembly and powers the system’s built in audio speakers. Tripath explained that its Class-T 1-bit digital audio amplifiers are semiconductor-based, and provide performance, power efficiency, size, weight and cost advantages over traditional amplifier technology. The digital amplifiers use multiple signal processing techniques, including adaptive/predicative processing, noise shaping, pre-distortion and sigma delta modulation.
Tripath vice president of worldwide sales and applications Alan Soucy said his company continues to work closely with Apple to provide audio solutions. “Tripath is greatly appreciative of Apple’s commitment to use Class-T digital audio amplifiers across their desktop products. They are clearly a leader in recognizing the growing trend for personal computers to perform well as an entertainment system,” he said.
