Dorval, Québec, Canada. Matrox Electronic Systems has announced an agreement with Matsushita Electrical Industrial Co. of Japan to use Matsushita codec technology in a DV/DVCPRO module that will plug into the Matrox DigiMotion™ board. The module will add realtime compression and playback of dual streams of DV or hybrid DV/motion-JPEG audio/video to the board’s capabilities.

The Matrox DigiMotion board and DigiSuite™ software provide a high-performance platform for the development of professional video/audio editing applications like Softimage™ Digital Studio (code name), D Vision PostSUITE-XED/II™ and others. Along with numerous advanced video and image processing capabilities, the DigiSuite environment includes a full-blown digital audio mixer.

Los Angeles, CA. Some of the most interesting new product action at last week’s World Media Expo and NAB Radio Show at the Los Angeles Convention Center was in the area of codec and remote link technology for sending high quality audio point-to-point via ordinary telephone service or ISDN lines. The most energetic manufacturer on the WME floor in terms of new products was MUSICAM U.S.A.

Leading the lineup for MUSICAM was an enhanced version of the CDQPrima™ series of codecs for ISDN, which the company claims is already the fastest-selling audio codec on the market. The key new feature of the enhanced model is the addition of Layer III MPEG compression capability. With Layer III, the CDQPrima can now deliver 15kHz mono audio over a single ISDN “B” channel.

Added to the unit’s implementation of enhanced Layer II MPEG (MUSICAM®), the Layer III capability makes the CDQPrima extremely versatile and compatible. In addition to high quality digital audio, mono or stereo, it delivers SMPTE timecode, two ancillary data channels, eight relay contact closures, plus command and control channels, all on a single ISDN line.

Also on the ISDN transmission front, MUSICAM unveiled two new portable codecs with built in mixing capabilities. The top-of-the-line Olympian™ offers bidirectional stereo audio with no compromises. It includes the same MPEG Layer II (MUSICAM) and Layer III algorithms as the codec-only CDQPrima series. In addition to mono and stereo transmission, it supports dual-channel send of separate mono programs over two ISDN “B” channels. It can also send voice-grade analog audio over standard phone lines, when ISDN is unavailable.

The company claims ultra-low distortion (0.01% THD+N) and superior signal-to-noise ratio (greater than 90 dB) for the Olympian. The standard configuration includes a built-in universal ISDN terminal adapter with integrated NT1, three mic inputs with stereo pan, a stereo line input, AES/EBU digital inputs and balanced line out. It also features numerous convenience features such as a snap-shot memory that saves presets of all operating parameters, including level settings, stereo pan position, ISDN numbers, bit rates, line format algorithm and mode, and sampling rate. The Olympian can match an incoming signal’s algorithm, mode, sampling rate and bit rate automatically.

For applications where absolute audio quality is less important, such as news gathering and voice over, MUSICAM introduced the RoadRunner™ portable codec/mixer. It offers similar automatic functions and convenience features as the Olympian, with MUSICAM enhanced Layer II and Layer III MPEG algorithms. But it is limited to mono send of a 15 kHz signal on a single ISDN “B” channel (or analog audio via standard phone line), has two mic inputs plus one mic/line input, and no digital I/O.

Finally, at the low end of its new product intros, MUSICAM brought out a studio version of its FieldFone audio codec for regular phone lines. The StudioFone™ is intended as the studio side of a field reporters’ link, enabling broadcast quality digital audio back to the studio via a single regular analog phone line. Both the FieldFone and the StudioFone offer frequency response approaching 9 kHz, and a “Sound Shaper” feature to sculpt the frequency response for optimum quality when sending music or other program involving higher bandwidth.

Los Angeles, CA. Audioarts Engineering, a division of Wheatstone Corporation, is preparing to introduce a new console at the World Media Expo and NAB Radio Show, which opens on Thursday (Oct.10) at the Los Angeles Convention Center.

The Audioarts R-5 on-air radio console will be available in the fourth quarter of this year for a list price of $5,795 (US). It delivers “better than 16-bit digital audio performance,” and it is targeted to small-market applications.

“With the introduction of this less expensive and feature-rich audio console, Audioarts is expanding into new markets, such as college and smaller market radio stations,” says Ray Esparolini, Director of Sales, Wheatstone Corporation.

“The R-5 is very versatile and can be used in many ways, possibly as the main control console in smaller market stations or as the secondary console in medium-sized markets.”

The R-5 is designed for easy installation. Among its features, the R-5 has two pairs of Sifam™ VU meters for stereo program and audition. All switches are LED illuminated for easy identification and low maintenance. It includes Audioarts exclusive Simple Phone™ mix-minus feature, which simplifies a busy station’s multiple call-in operations; full function tape remote controls; and four microphone pre-amps. The new console also provides electronic switching throughout and two inputs per channel.

Also going on display at the Wheatstone booth at Radio World (booth #2043) will be a new line of studio furniture for radio stations, featuring a designer look. The U-shaped counter array of the new line includes a sweeping curve toward the interview area, and an interview counter that is kidney-shaped. The furniture includes a substantial amount of storage space, as well as generous wire raceways, and hinged punch block panels.

“This new line incorporates a highly stylized approach to radio console furniture,” explained Wheatstone President Gary Snow. “The design is based on a curved style of architecture. It includes a beautiful combination of hardwoods and laminates. The cabinets have hardwood rounded corners. It is extremely refined furniture, the kind an architect would select if he or she were designing the interior of a radio station.”
