The Audio-Technica ATW-3211N/831 is a 3000 Series (4th generation) network-enabled rackmount wireless lavalier microphone system with professional-level features for enhanced reliability and control. It offers Ethernet networking for quick multichannel setups and an intuitive interface with a dual-mode OLED display for easy operation. With a wide 60 MHz tuning range and true-diversity reception, the system minimizes potential dropouts to deliver intelligible, natural audio for presenters, clergy, lecturers, and performers working in business and educational settings, houses-of-worship, theaters, or on musical stages.
The ATW-3211N/831 includes a half-rack receiver housed in a rugged, full-metal chassis with removable antennas, well suited for rackmounting in portable flight cases or permanent installations. The receiver's auto-scan function searches 2395 selectable frequencies, seeking out a clean, interference-free channel for your audio transmission. The 3000 Series lets you set a clean backup frequency in advance, which you can quickly switch to with a press on the transmitter's multifunction button in the event of unexpected interference.
This system features an AT831-cH cardioid lavalier mic that provides crisp, full-sounding voice pickup, while also excelling as an instrument mic. The bodypack transmitter is equipped with a rugged metal housing and a proprietary Hirose 4-pin cH-style screw-down connector for secure connection. The transmitter provides up to 9.5 hours of operation on two AA NiMH rechargeable batteries (available separately), with a selectable 10/30mW RF power output for overcoming interference in difficult RF environments. The transmission range is up to 330'.
The Ethernet connection on the receiver allows multiple receivers to be easily networked together for simplified frequency coordination and deployment via Audio-Technica's Wireless Manager Software (WMS). Up to 40 mic channels can operate simultaneously in each frequency band.
Compact Bodypack with Cardioid Lavalier for Hands-Free Presentations
- The AT831cH lavalier features a cardioid pattern for significant rejection of unwanted background sound and reduced feedback on stage.
- The bodypack transmitter features a rugged Hirose 4-pin cH-style connector, which provides secure connection to compatible lavalier mics, headworn mics, and cables.
- The transmitter's input accepts low-impedance microphone levels as well as high-impedance musical instrument or line levels. The gain ranges from -10 to +20 dB and can be adjusted in 2 dB increments.
- The bright OLED screen presents comprehensive setup and operating information, including battery indicator, mute status, and operating frequency. Setup functions are menu-driven via soft-touch controls, which are covered to prevent accidental changes.
- A tactile mute toggle switch (defeatable) provides physical confirmation of mute status when transmitter display is not visible.
- The transmitter easily syncs to the receiver via infrared with a quick press on the Sync button.
- Two RF power output settings are available: the low-level setting extends battery life while the high-level offers a stronger RF signal link.
- In case of interference, the programmable multifunction button on the transmitter can be used to switch to a clean, backup frequency with minimal interruption.
- The transmitter operates for up to 9 hours on two AA alkaline batteries and up to 9.5 hours on two rechargeable AA NiMH batteries.
- Charging terminals on the base of the transmitter work with the optional ATW-CHG3 charging dock or ATW-CHG3N networked charging dock to recharge AA NiMH batteries.
- The durable metal chassis is equipped with a field-replaceable whip antenna and a secure, locking battery compartment door.
Reliable Receiver That's Easy to Use
- The wide 60 MHz UHF bandwidth gives you 2395 selectable frequencies to choose from for interference-free audio transmission in an increasingly congested RF environment.
- To prevent dropouts, the receiver's true-diversity reception compares incoming signals on two independent receiver circuits to ensure optimal RF quality.
- Auto-frequency scanning automatically selects the most appropriate frequency for the area in which the wireless is operating.
- Pre-coordinated frequency scan groups are available to simplify selection of usable frequencies in a multichannel wireless setup.
- The bright, dual-mode OLED display can be switched between two modes: the standard view provides continuous indication of RF signal strength, frequency, mute status, audio modulation level, and transmitter information, while the performance view highlights key metering.
- The display also shows the transmitter's battery life and mute status.
- Settings can be quickly adjusted using the control dial and BACK button located on the receiver's front panel. Settings can also be locked to prevent accidental changes.
- The BNC sockets for the two detachable antennas provide bias power to active remote antennas and other in-line RF devices.
- The ground-lift switch on the back panel helps eliminate audible hum caused by ground loops.
- One balanced XLR audio output lets you connect the receiver to a mixing board or PA system.
- The half-rack receiver chassis can be mounted alone in a standard 19" rack using the included mounting brackets and screws.
Network-Enabled for Simplified Setup and Operation
- The receiver features an Ethernet port, allowing users to configure, monitor, and control the system’s components remotely from a computer running Audio-Technica’s Wireless Manager software (WMS)—free download available separately.
- Once it identifies the cleanest channels, WMS takes into account intermodulation issues, builds a frequency plan for you, and deploys those frequencies to the networked receivers—saving you a lot of setup time and headaches.
- During the performance, you can use the monitor page to stay one step ahead of potential problems by keeping an eye on RF, AF, and the remaining battery life of the transmitters.
Enhance the Performance of Your System
- Adding a pair of ATW-A49 LPDA directional remote antennas increases the range of your system and offers more protection against interference.
- The optional RF Venue DISTRO4 four-channel antenna distribution system allows you to distribute the RF signal from the remote antennas to four discrete 3000 Series receivers.
Add Functionality to Your System
- The comfortable BP892xcH earset mic and the discreet BP893xcH miniature MicroEarset mic provide exceptional clarity in spoken word applications.
- The ATW-T3202 handheld transmitter/mic is available with a variety of mic capsules for presenters and performers who prefer the flexibility of a handheld microphone.
