New digital audio adapter offers high-performance, broadcast-quality stereo sound at an unprecedented low cost.

GARDENA, Calif.--(BUSINESS WIRE)--July 15, 1996--With the introduction of the model SX-34 digital audio adapter, Antex Electronics now offers personal computer users and systems integrators broadcast-quality audio with MPEG compression at a fraction of the cost of high-end solutions.

Featuring multi-channel, ultra-high fidelity, direct-to-disk, digital sound sampling and reproduction, the SX-34 offers users the ability to enhance their applications with high performance digital audio record and play functions with industry-standard MPEG Layer I/II and other compression formats.

The SX-34 is ideal in digital audio mastering and recording; computer aided learning systems; audio/visual multimedia presentations; music and entertainment; kiosks, and other integrated computer audio systems.

Designed in the rich technical tradition of the ANTEX Series 2 family of digital audio adapters, the SX-34 boasts ISO/MPEG Layer I/II bit rate reduction technology for compression rates of up to 16:1. The SX-34 features a unique dual device design, giving the user the ability to record on one stereo channel, while playing back on another.

Compatible with 80386/486/Pentium and PS/2 ISA, the SX-34 is a fully ISA-compatible 1/2 size add-in card. The smaller size of the card is ideal for computers with limited space.

Despite its low cost, the SX-34 hasn't sacrificed the quality of its audio signal or components. It offers multiple sampling rates of 5.1 kHz and 48 kHz, a 16-bit input resolution with 64x oversampling Sigma Delta conversion. An on-board buffering scheme allows for glitch free data transfer (2.5 times faster than DMA transfers).

The SX-34 features mic, line and aux inputs. An on-board audio mixer with complete mixing capabilities is also included. And, because the SX-34 incorporates a Texas Instruments Digital Signal Processor, the format for audio data is completely user programmable.

In addition to ISO/MPEG Layer I/II, the SX-34 offers MS ADPCM, IMA ADPCM, OKI ADPCM, CD-ROM XA, 8 and 16-bit PCM. Antex provides drivers for both DOS and Windows, and the Model SX-34 is fully supported under the Microsoft multimedia extensions.

To utilize all the SX-34's features and maximize its capabilities, Antex Electronics offers a high level digital audio Application Program Interface (API) for DOS. Languages supported include C, Pascal, BASIC, and Assembly. The drivers are available as an Audio Developers Kit (ADK) in either a TSR or Linkable version and are downward compatible with existing Antex drivers.

The new Series 2/Model SX-34 Digital Audio Processor is designed and manufactured in the United States by Antex Electronics, 16100 S. Figueroa St., Gardena, Calif., 90248, telephone [phone], fax [phone].

The company offers over 25 models of digital audio and multimedia boards and now has over 70,000 professional audio adapters in use around the world. The Model SX-34 is available not at a list price of $695. The Audio Developers Kit (DOS) has a list price of $750.
