Micron TX700 Pocket Transmitter
The Micron TX700 is a professional UHF bodypack transmitter developed for broadcast, television, film, ENG and location sound recording. Designed around a low-noise voltage-controlled oscillator (VCO) with digitally controlled PLL circuitry, the TX700 delivers exceptionally clean RF transmission and the renowned audio quality expected from the Micron 700 Series.
Constructed from a rugged one-piece aluminium extrusion, the TX700 is lightweight yet durable enough for demanding production environments. The transmitter features adjustable audio gain with peak-level LED indicators, a user-adjustable soft limiter, bass-cut filter and phase-reverse switch, allowing engineers to optimise performance for a wide range of microphones and recording situations.
Compatible with both microphone and line-level sources via dedicated input leads, the TX700 also provides remote low-battery signalling to compatible Micron receivers, ensuring reliable operation during live productions and location shoots.
