Audio-Technica SpectraPulse mtu301 Body-Pack Transmitter

FOH Staff • New Gear • June 22, 2011

Audio-Technica's SpectraPulse mtu301 Body-Pack Transmitter lets presenters transmit audio as they move throughout the entire SpectraPulse coverage area. By plugging in a lavalier or head-worn microphone to the mtu301, users can leave a podium or walk away from a conference table, expanding the performance for Audio-Technica's SpectraPulse Ultra Wideband (UWB) wireless microphone system. An application of UWB technology, SpectraPulse offers secure wireless operation for the installed sound market, free from RF competition, frequency coordination and "white space" issues.
The mtu301 joins the SpectraPulse mtu101 Microphone Transmitter Unit (in a boundary mic design) and mtu201 XLR Desk Stand Transmitter (paired with gooseneck mics) to offer more flexible options for presenters and performers. Like the other SpectraPulse components, the mtu301 is designed to be immune to 700 MHz and spectrum-crowding issues. The mtu301 is optimized to work with Audio-Technica lavalier and headworn microphones pre-terminated with a compatible input connector. The unit provides bias voltage for electret condenser microphones.


The mtu301 includes an on/off switch, a mute switch and LEDs indicating power/mute and link status, as well as low-battery warning. The unit operates on standard Alkaline or NiMH (Nickel Metal Hydride) rechargeable AA batteries. A charger (model chg001; available separately) allows NiMH batteries to recharge within the unit. The mtu301 offers approximately nine hours of battery life.


The mtu301 and chg001 are now available with respective MSRPs of $1,450 and $112.
