Studio Network Solutions ( showed Postmap, a Mac/Win search/management app that helps users instantly locate files on their entire storage systems: SAN, LAN, CD/DVD and FireWire drives. Postmap includes a powerful metadata management and workflow engine that can be configured to address the needs of any workgroup.

With as-yet-unresolved FCC frequency allocation changes in the wind (see “The Sky Is Falling” in the April 2007 issue of Mix). NAB attendees had more than a casual interest in new wireless developments. Here are some that caught our attention.

Sony Pro Audio ( showed its digital wireless system featuring a digital modulator and encryption scheme. The system—now in use working a reality show in L.A.—is capable of 12 channels simultaneously on a 6MHz bandwidth TV channel. An innovative Sony codec chip helps the system deliver 24-bit/48kHz digital transmission quality with reliable, secure, low-latency operation and up to 50-percent more simultaneous channels than conventional analog systems.

Mipro (dist. by Avlex, is shipping its single-channel ACT-81 and dual ACT-82 digital wireless systems. Both use a sub-band ADPCM algorithm that's said to eliminate compander noise. Price is roughly $3,500 per channel.

Ideal for use with shotgun mics (handheld or boom), the plug-on Zaxcom ( TRX700 recording transmitter stores up to 12 hours of timecode-referenced audio on a removable miniSD card. Offering some safety in these days of crowded airwaves, this patent-pending feature provides an automatic back-up of the system's RF transmission.

Audio Technica ( touted its 1800 Series dual-channel UHF wireless system with a built-in mixer in the camera-mount receiver that lets users mix two input sources in the field. The system comes with either a beltpack transmitter or mic-end XLR transmitter, plus the receiver/mixer. Some 996 UHF frequencies are available and single-channel systems are also offered.

Sennheiser ( showed its EK3241 camera-mount portable receiver with 32MHz switching bandwidth and 7,200 available frequencies. A new Command Channel function can open a secondary audio channel for use in a variety of broadcast applications. 

NAB featured a multitude of interesting new mics for high-res and multichannel production. DPA ( showed its first shotgun, the 4017, an 8.3-inch, 2.6-ounce unit with 130dB SPL handling, a built-in 50Hz roll-off and switches for a 300Hz roll-off and a 5k to 8k boost.

Sony ( unveiled the feather-light ECM-680S, which can function as a shotgun, stereo or mono mic. If one side of the stereo feed goes out, the mic adjusts and sends the output as dual mono for worry-free field recording.

HHB ( expanded on its original FlashMic—which combines an omni Sennheiser capsule and a broadcast-quality Flash recorder—with the DRM85-C cardioid model. Both FlashMics feature 1GB Flash memory for more than 18 hours of recording, USB audio transfer, full manual or automatic gain control and nine user templates for configuring the unit using the supplied FlashMic Manager software.

A new, affordable model from SoundField (, the SPS200 can produce simultaneous phase-coherent stereo and 5.1 if required, decoding its output to the required formats via two cross-platform plug-ins. The mic also features remote control over pickup pattern and orientation without moving the mic.

Sanken's ( WMS-5 delivers phase-coherent surround sound with five discrete outputs (L/ C/R/Ls/Rs) from one compact 9.25-inch/8.3-ounce body. The "M" capsule is used for both a shotgun-directivity Center and front Left/Right. The "S" signal is utilized for both front Left and Right and rear Left Surround, Right Surround. A rear "M" capsule is used for Left/Right Surround.

Beyerdynamic ( debuted the MCE 72 PV CAM camera-mountable stereo mic. Based on the consumer MCE 72, the new MCE 72 PV CAM runs on 11- to 52-volt phantom power for a hotter output signal and includes a cable with standard 3-pin XLR outputs.

Digidesign RMS active monitors

Digi monitors? Developed jointly with PMC, Digidesign's ( RMS series active bi-amped monitors are offered as 5.5-inch two-way (RM1) and 6.7-inch two-way (RM2) versions, both with DSP-based digital crossovers and XLR analog and AES/EBU digital inputs. All models employ PMC's Advanced Transmission Line technology. Shipping in May 2007, the RM1s are $1,249/each; the RM2s are $1,749/each.

Genelec ( announced that the speaker management software for its DSP driven monitors is now available for both PC and Mac. The software lets users run Genelec's AutoCal room correction and control up to 25 8200 speakers and five 7200 series subs via standard Cat-5 cabling.

Mackie ( unveiled the second generation of its HR monitors. The new THX-approved HR824mk2 and HR624mk2 have a cast-aluminum enclosure with a Zero Edge Baffle for minimal diffraction. Both have 1-inch titanium dome tweeters paired with 6.7-inch (HR624mk2) or 8.75-inch (HR824mk2) woofers and a passive radiator.

A "different" kind of monitor, DK-Technologies' ( new Starfish display for its MSD600M audio meters shows levels for each of the surround channels, along with the perceived acoustic level. The Starfish's colored contour reflects the correlation between neighboring audio channels, making unwanted effects easy to track down, and stereo/mono downmix signals are displayed to ensure compatibility.
