Coffeey Sound offers new Sony wireless mic system

January 5, 2009

After a series of extensive field tests, Los Angeles rental house Coffey Sound is now offering its TV production clients Sony’s latest digital wireless microphone system, which includes the DWT-BO1 body-pack transmitter and DWR-S01D digital wireless receiver.

Bryan Golder, an LA-based producer/engineer and consultant for Coffey Sound was the first to test the system’s capabilities and said it provided flawless performance, even under harsh conditions.

For the test, Golder used an M/S microphone mounted to the Sony EX3 optical disc camcorder. He used the new Sony DWT-BO1 body pack transmitter mounted on a Zacuto wireless plate (part of the Zacuto rod system) as a stereo hop back to the stage. From there, all the signals were returned to a production truck on-site through a Digidesign Venue system. It performed flawlessly at distances of over 100ft.

Golder monitored the feed to the DWR-S01D digital wireless receiver with a pair of Sony MDR-7506 headphones. He said he likes that the body pack transmitter accepts mic or line input, and selectable output power for stable and long-distance transmission. It performed flawlessly at distances of over 100ft. He also liked the easy-to-read, full dot-matrix organic EL display.

A recently developed Sony codec chip enables the DWT-B01 and DWR-S01D units to deliver 24-bit/48kHz digital wireless audio transmission quality. The new wireless mic system features low latency, a wide dynamic range of more than 106dB, a wide frequency response of 20Hz to 22kHz, and exceptional transient response. Digitally modulated and encrypted data helps provide secure transmission and minimizes the risk of interception. It also features a dot-matrix organic EL display.

Thanks to a newly developed modulator, the system provides an intermodulation-free, equally spaced channel allocation for large-scale multichannel operation. Compared with analog, the system offers 50 percent more wireless channels, allowing up to 12 channels to be used simultaneously on a single UHF TV channel (6MHz bandwidth).

In addition, a DWA-01D adapter, which complements the system, includes two-channel AES3 digital or analog audio output; headphone output for monitoring (stereo mini-jack); external DC power input via supplied 4-pin cable; word sync input; and it is suitable for stand-alone EFP digital audio operation using an external pack.
