Micron Explores New Wireless Territory
January 2004

Micron Explorer Transmitter and camcorder-mounted Receiver

Audio Engineering, manufacturer of the Micron range of high performance wireless audio equipment, has announced the launch of its Explorer Series radio microphone systems. Introduced at a highly affordable price point, the new Micron Explorer Series comprises the TX700-A Pocket Transmitter and the SR550 Small Receiver, together with powering, camera-mounting and microphone options.

The Micron Explorer products feature rugged metal construction, using a high-strength yet lightweight one-piece aluminium extrusion, with robust long-life connectors. They are designed for operation with DV camcorders, for creating mixer-to-camera wireless links, and for general location recording and ENG applications. Switchable across 100 frequencies, the Explorer Series is available with a choice of RF bandwidths up to 32MHz, to provide videographers, freelancers and OB crews alike with a high degree of operational flexibility and freedom for international working.

Aldo Hakligil, managing director of Audio Engineering Ltd, commented:

"With the launch of our Micron Explorer series, we are continuing our tradition of providing wireless technology that is specifically designed to offer the optimum combination of audio and RF performance, together with long-term reliability. The Explorer products offer new levels of real-world survivability and operational flexibility at an extremely competitive price, ensuring that these broadcast-quality systems are as attractive to freelance videographers as they are to broadcasters and location recordists."

Catering for both mic and line-level inputs, the Explorer TX700-A transmitter provides level adjustment via a secure top-panel control, with a peak-reading LED level indicator. Capable of handling very high input levels, with generous headroom, the TX700-A includes a fast-response limiter with a soft curve, specifically set up to avoid clipping on peaks. This can also act as an automatic gain control, to enable operation with lower-budget camcorders or mixers.

The TX700-A can supply power for a variety of microphone types, including T-powering low-voltage condensers and P48 phantom-powered designs. Equipped with a battery-status LED indicator, the transmitter can be powered by alkaline or lithium ion batteries, with the Explorer’s unique battery compartment – designed to withstand the heavy demands of location use – enabling quick and simple battery replacement.

Designed with the new generation of DV camcorders in mind, the Micron Explorer SR550 is an ultra-compact receiver. Particularly useful in situations where receiver size and weight are important, the SR550 is small and light enough for easy mounting on camcorders, via optional adapters. The receiver offers 100 frequencies across a 32MHz or 24MHz bandwidth, depending on regional or national requirements, to avoid interference from local RF sources and to provide maximum flexibility for location sound and outside broadcast applications.

The SR550 features multiple RF stages to give high sensitivity and selectivity, while the receiver's unique noise reduction system is designed to provide trouble-free operation in low RF signal situations, and even in hostile RF environments. Audio output level is via a three-position switch, to match the input requirements of camcorders, mixers and ancillary systems. Two 3-colour LED displays provide continuous information on received signal strength and battery condition, and the SR550 can be powered from an internal battery, or from an external source via the unit’s multi-pin input connector. Featuring the same battery compartment design and case construction as the TX700-A, the receiver represents a high-quality product, engineered for reliable long-term operation.
