Audio-Technica’s completely new application of proven, patented Ultra Wideband (UWB) technology, SpectraPulse UWB Wireless Microphone System bypasses the increasingly congested RF bottleneck to deliver clear, intelligible audio without the performance and set-up issues associated with conventional wireless systems.
Designed for conferences, courtrooms, corporate events and more, SpectraPulse offers 14 simultaneous channels that operate flawlessly without RF turf wars, frequency hunting/coordination, “white space” issues, or interference.
Secure
SpectraPulse offers levels of security that have never before been commercially available in wireless microphones. For ultimate security, A-T’s optional encryption package meets the NIST-approved AES encryption standard developed by the U.S. government for safeguarding sensitive material.
Simple & quick to install
For the contractor or system integrator, setting up a SpectraPulse system is simple and quick. Install the Digital Receiver Module (drm141) and connect it to the equipment rack via a standard shielded Cat-5 cable.
In the rack, install up to two Audio Control Interface (aci707) units for a total of 14 separate microphone channels. Place up to 14 Microphone Transmitter Units (mtu101) out in the environment as required and set their individual addresses. Turn the system on, and SpectraPulse is ready to go. There is no frequency scanning or channel planning required.

SpectraPulse™ system features
- Ultra Wideband (UWB) wireless operation— Delivers clear, intelligible audio with none of the performance and set-up issues associated with conventional RF wireless microphone systems.
- Easy to set up and operate—Designed for quick, intuitive setup and user-friendly operation.
- Interference-free performance—Very few RF devices are approved to operate in the frequencies where SpectraPulse UWB wireless microphone system operates.
- No problems in crowded RF environments—Bypasses the increasingly congested UHF, VHF and 2.4GHz frequency bands; ideal for use in areas with high RF congestion.
- No frequency hunting or coordination—14 simultaneous channels operate with no frequency coordination required. Channel selection is quick and easy.
- Immunity to multipath interference—Offers extremely reliable performance; no dropouts or sputters.
- Inherent security—UWB data is transmitted in extremely short-duration pulses sent in a timed sequence over a wide frequency spectrum. To decode the pulses, the Digital Receiver Module must know exactly when, where and how to listen. This makes SpectraPulse inherently secure.
- Encryption available—Optional encryption package meets NIST-approved AES 128-bit encryption standard developed by the U.S. government for securing sensitive material.
- Excellent audio quality—Digital signal requires no compression; imperceptible latency; microphone muting is silent.
- Universal interface—Connects with teleconference systems, videoconference systems, PA/local sound systems, archive recording and logging systems.
- Contact closure input/output (on Audio Control Interface) —Provides control interface with external devices.
- Flexible performance—Soft-touch button on boundary microphone/transmitter is configurable for push-to-talk, push-to-mute, and toggle operation.
- Minimal Rack Space Required—7 channels in 1 rack space, 14 channels in 2 rack spaces.
- Optional rechargeable batteries and charging/encryption station— Rechargeable AA NiMH batteries are included with the cei007 Charging/Encryption Interface.
