SpectraPulse® Ultra Wideband (UWB) Wireless Microphone System

Audio-Technica’s innovative application of pure digital Ultra Wideband (UWB) technology, the award-winning 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® delivers license-free plug-and-play simplicity, rock-solid performance, and impenetrable security. Operating in the sparsely populated 6-10 GHz range, SpectraPulse® systems are completely out of the range of TV signals and white space devices. With no companding or compression circuits to diminish signal quality, and no need for frequency coordination, SpectraPulse offers extremely straightforward setup/operation along with all-digital clarity and versatility.

Secure
Operating with an average transmit power that is below the ambient RF noise floor and with pulses only 2 nanoseconds in duration, SpectraPulse offers levels of security that have never before been commercially available in wireless microphones. The inherently secure system offers an optional 128-bit AES encryption package for customers who want to use SpectraPulse® systems in sensitive environments.

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. For expanded coverage area and use in adjacent rooms, install an rcu104 receiver coordinator unit in the rack and use up to four drm141 Digital Receiver Modules. Place up to 14 Microphone Transmitter Units out in the environment as required and set their individual addresses. You may use mtu101 Boundary Microphone Transmitters, and/or mtu201 XLR Desk Stand Transmitters combined with Audio-Technica Engineered Sound® gooseneck microphones, and/or mtu301 Body-pack Transmitters paired with lavalier or headworn microphones (mtu301 transmitters can be used with systems utilizing 2 or more drm141 Digital Receiver Modules). Turn the system on, and SpectraPulse is ready to go. There is no frequency scanning or channel planning required.

    SpectraPulse® System Features
  • Digital—SpectraPulse® pure digital technology delivers remarkable sound and connectivity.

  • 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.

  • Available with body-pack transmitters—Paired with a lavalier or headworn microphone, the mtu301 Body-pack Transmitter allows speakers to transmit audio as they move throughout the SpectraPulse® coverage area in systems utilizing 2 or more drm141 Digital Receiver Modules

  • 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 the 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.

  • Available with receiver coordinator unit—Pair the rcu104 Receiver Coordinator Unit with up to four Digital Receiver Modules for expanded coverage and use in adjacent rooms.

  • Optional charging station— Rechargeable AA NiMH batteries are included with the chg004 charging station.

  • Affordable—Extremely cost-competitive with traditional FM wireless.

Answer: 
Thank you for your inquiry. That would depend upon the distance the systems are apart and how well shielded the rooms are against RF. Please contact our Audio Solutions team at 330 -686-2600 ext 5000 and they would be happy to help you with this.

Multi drm141 installation question?

I am installing 3 drm141's in a large room. Do all 3 drm141 cables have to be the same length or can one be on a 25' cable, another on a 75' cable, and the last on a 100' cable?
