Audio-Technica ATW-3211 3000 Series Frequency-agile True Diversity UHF Wireless Systems

Highlights

• Extremely wide 60 MHz UHF tuning bandwidth for maximum versatility in an increasingly congested RF environment
• Available in two frequency bands: DE2 (470–530 MHz) and EE1 (530–590 MHz)
• Up to 40 simultaneous channels per band (open-range environment with no interfering signals)
• Unique multifunction button on transmitters can be used to switch to a backup frequency (on both transmitter and receiver) should interference be encountered
• Auto Squelch feature automatically adjusts squelch setting to maximize range while minimizing potential interference

Description

The fourth-generation 3000 Series frequency-agile True Diversity UHF wireless systems offer rock-solid, latency-free, high-fidelity RF audio performance. Each system offers a 60 MHz tuning bandwidth in one of two available frequency bands: 470.125–529.975 MHz or 530.000–589.975 MHz. High-sensitivity, dual-conversion True Diversity operation with silent automatic switching provides dropout-free performance. The 3000 Series receiver and transmitters feature easy-to-use controls for quick access to a large range of functions, and an OLED screen for convenient visual indication of settings and operating information.The ATW-R3210 receiver features automatic frequency scanning that eliminates the need for searching for clear channels by automatically selecting the most appropriate frequency for the area in which the wireless is operating. 25 kHz frequency spacing enables the system to easily find an open frequency in crowded RF environments, while pre-coordinated frequency scan groups simplify selection of usable frequencies in a multichannel wireless system. Once selected, frequencies can be synced with transmitters using the system’s IR sync functionality. The system’s squelch setting can be configured to automatically adjust to maximize range while minimizing potential interference. Advanced digital Tone Lock squelch provides enhanced rejection of interference. In addition, the Tone Lock signal from the transmitter also conveys information on the transmitter’s battery condition and mute status back to the receiver for display. The receiver’s dual-mode front panel display can switch between the standard view, which provides continuous indication of RF signal strength, frequency, mute status, audio modulation level of the received signal, and transmitter information, and a performance view, which highlights key metering. Settings can be easily adjusted using the control dial and BACK button located on the receiver’s front panel. Settings can also be locked to prevent them from being changed.Operating on 12V DC, the receiver incorporates rear-panel connections for balanced XLR and unbalanced ¼" outputs, along with detachable BNC ¼" wave antennas. Switchable 12V DC antenna power is available on the BNC-type connectors for powered antenna accessories. The receiver is half-width for a standard 1U 19” rack-mount and includes rack-mount adapters.All transmitters operate using two AA batteries and feature high- and low-level RF output settings. The low-level setting extends battery life while retaining a strong RF signal link. Charging terminals on the base of each transmitter work with the optional ATW-CHG3 and ATW-CHG3N charging docks to recharge AA NiMH batteries. Each transmitter’s OLED screen presents a great deal of 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 activation. A dual-color status LED illuminates green when power is on and red when the transmitter is muted or battery power is low.Transmitters have a selectable high-pass filter and a gain setting that can be adjusted in 2 dB increments. As with the receiver, transmitter settings can be locked. The ATW-T3201 body-pack transmitter features a tactile mute toggle switch (defeatable) for physical confirmation of the mute status when the transmitter display is not visible. It also has a multifunction button that can be programmed to perform one of two functions when pressed and held: turn off RF transmission or switch to a preselected backup frequency to avoid interference. (The multifunction button can also be disabled.) An input is available on the transmitter for low-impedance microphone, and high-impedance musical instrument or line input. The transmitter supplies 5V DC bias to power condenser microphones
