SUNNYVALE, Calif. -- Mitsubishi Electronics America Inc. today announced a new sound processor that integrates the QSurround 5.1 technology from QSound Labs Inc. The M65857FP processor is the latest device to come out of last year's technology alliance between Mitsubishi's Electronic Device Group and QSound Labs of Calgary, Alberta, to support surround-sound effects in consumer audio applications.
Mitsubishi said its new processor makes end-product designs easier because no large decoding circuits are needed for QSurround 5.1 technology. The technology creates surround-sound effects with "virtual speakers." This capability generates surround-sound effects from any mono or stereo input signals. Surround-sound effects can be generated from two physical speakers.
"Combining QSound's QSurround 5.1 technology with Mitsubishi's digital delay technology effectively provides a realistic 5.1-speaker surround soundeffect for a vast array of consumer audio products, which traditionally have
been only stereo or two-channel output," said George Riehm, senior marketing
manager for consumer products at Mitsubishi's subsidiary in Sunnyvale.
The new sound processor uses a 5-volt power supply and has a 30-mA current specification. It has a maximum output voltage of 1.4 V RMS.
Sample of the M65857FP processor will be available in July, and priced at $7 each. The device is housed in a 36-pin SSOP package with 0.8-mm pitch spacings between interconnects.
