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.

The rugged cH-style screw-down 4-pin input connector provides secure connection to cH-style lavalier mics, headworn mics, and cables. The durable metal body-pack transmitter features a field replaceable whip antenna, OLED screen, and a secure, locking battery compartment door.The ATW-T3202 handheld transmitter offers extremely low handling noise and comes with either an ATW-C510 dynamic or ATW-C710 condenser interchangeable cardioid capsule. Each capsule features an integral two-stage pop filter within the rugged steel headcase to protect against “p” pops and other breath plosives.

The transmitter’s industry-standard thread mount also allows it to be used withadditional Audio-Technica capsules (available separately) and other compatible capsules. Its multifunction button can be programmed to perform a specific function when pressed and held: mute the audio; mute the audio even when the transmitter is locked; turn off RF transmission; or switch to a preselected backup frequency to avoid interference. (The multifunction button can also be disabled.)

The transmitter housing is made of metal with an integral antenna and an OLED screen. Each handheld transmitter includes a heavy-duty Quiet-Flex™ stand clamp.The ATW-CHG3 two-bay charging dock (available as an optional component) charges NiMH batteries that are installed in the transmitters. The dock automatically shuts off if alkaline or damaged batteries are detected in the transmitters. Up to five docks can be linked and powered by a single power supply. The ATW-CHG3N networked version of the charging dock allows users to monitor the charging status of all transmitters in the linked dock transmitters. The dock automatically shuts off if alkaline or damaged batteries are detected in the transmitters.

Up to five docks can be linked and powered by a single power supply. The ATW-CHG3N networked version of the charging dock allows users to monitor the charging status of all transmitters in the linked docks.Architect’s and Engineer’s SpecificationsThe frequency-agile FM wireless microphone system shall consist of a receiver and the appropriate transmitter, and shall operate in the UHF bands of 470.125–529.975 MHz or 530.000–589.975 MHz. The frequency-agile FM wireless receiver shall be all-metal and shall provide an automatic scanning function to select appropriate local usable channels for proper wireless system operation. It shall be a True Diversity receiver with two independent internal receiver sections, automatically selecting the highest quality signal for the receiver’s output.

All receiver settings shall be adjusted by using a control dial and BACK button on the receiver’s front panel. The system will be equipped with an advanced pilot tone digital identification system to ensure that the desired wireless transmitter allows the receiver to be unmuted, reducing noise from unwanted signals. The receiver shall have an IR sync window on the front panel to sync settings with transmitters. It shall also have a dual-mode front panel display that switches between a standard view, which provides continuous indication of RF signal strength, frequency, mute status, audio modulation level of the received signal and other transmitter information, and a performance view, which highlights key metering.

The receiver shall have a rear panel selector to lift the ground connection from pin 1 of the XLR-type output connector to prevent ground loops. The receiver shall be able to be powered by 12V DC 1A. Antennas shall be located on the rear of the receiver and shall incorporate standard BNC-type connectors to allow them to be detached from the receiver to facilitate the receiver being used with external antennas or antenna distribution devices. Switchable 12V DC power shall be provided on the BNC-type connectors. An accessory bracket should allow for the antennas to be located at the front of the receiver.

The receiver can be rack-mounted singly or in pairs in a single rack space. The receiver’s design shall provide totally silent audio output mute when the wireless transmitter is turned off or the signal is lost. The wireless receiver and the supplied metal rack-mounting brackets shall be industrial black.The frequency-agile FM wireless body-pack transmitter shall have microphone and instrument level inputs. It shall provide DC voltage to power microphones requiring DC bias. The body-pack transmitter shall be part of a wireless microphone system operating in the bands of 470.125–529.975 MHz or 530.000–589.975 MHz. The body-pack transmitter shall have a reversible clip allowing for up or down cable entry. The transmitter shall have a screw-down 4-pin connector and a viewable fuel gauge to indicate the remaining battery life.

Frequencies shall be selected using the transmitter’s soft-touch controls. The transmitter shall also be equipped with 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.
