This D50 2-channel body-pack system features the Audio-Technica LINK-enabled 2-channel receiver, two ATW-DT3201 compact body-pack transmitters, and two AT831cH wireless clip-on lavalier mics.The half-rack receiver operates in one of two switchable RF modes: normal mode (Antenna Combining Diversity) or robust mode (MRC True Diversity) for greater RF stability. Up to four receivers can be linked and operated without antenna distribution, requiring only a single pair of antennas. Plus, the systems HD (high-density) mode gives users the option of expanding the number of usable frequencies from the standard 17 within a 6 MHz TV channel block to 47 frequencies in HD a feature that can be especially useful in the congested RF environments of large cities.The receiver comes with an AC adapter, but can also be powered by PoE+, either exclusively or as a backup power source for the AC.The ATW-DT3201 is a compact body-pack transmitter equipped with a cH-style screw-down 4-pin input connector for secure connection with compatible lavalier mics, headworn mics, and cables. External control buttons and an OLED status display make the transmitter easy to use, and a special SideTrack function allows users to switch audio to a second output providing discrete live communications with fellow performers or audio engineers.The transmitter is powered by a custom-designed lithium-ion battery, providing best-in-class battery life. The battery can be charged in the transmitter, using the ATW-CHG6 two-bay charging station (sold separately), or can be removed from the transmitter and charged separately in the ATW-CHGA6 battery charger (Included with this system).The AT831cH wireless clip-on lavalier mic provides crisp, full-sounding voice pickup, and offers excellent gain before feedback and suppression of background noise. Includes windscreen and clothing clip.Main Features:ATW-DR3220LK Receiver Features- Audio-Technica LINK-enabled, 2-channel, half-rack receiver- Full tuning bandwidth of up to 244 MHz, depending on region (up to 138 MHz in the U.S.), in the broadcast range enables flexible channel planning in complex RF environments- Switchable between normal mode (Antenna Combining Diversity) and robust mode (MRC True Diversity), which offers superior RF stability- User can switch from Standard mode (17 frequencies per 6 MHz TV channel) to HD mode (47 frequencies per 6 MHz TV channel) when operating in congested urban RF environments- Onboard DSP offers high-pass filter, 4-band EQ, and compressor settings for each channel- Supports AES256 encryption for superior security- Equipped with a network port for monitoring and device configuration via Wireless Manager- Receiver can be powered by included AC adapter or PoE+; PoE+ also provides redundancy to keep the receiver powered if AC drops out- Receiver can be set to mixed output in situations where input channels are limited- Spectrum analysis (accessible via receivers front-panel display and/or Wireless Manager software) and IR sync functionality make setup easy- Wireless Managers system management tools include those to configure detailed EQ and COMP settings, and an advanced walk test for visual confirmation of multiple RF conditions- Multipoint receiver function allows a transmitter to be detected by multiple D50 networked receivers, with Wireless Manager software automatically switching to the receiver that has the best signal- Included short and long rack ears can be used to mount one receiver in a half-rack space and two long ears can be combined as a joining plate to mount two receivers in a full space- TAA-compliant (U.S.); Radio Equipment Directive (RED) cybersecurity-compliant (EU)- Firmware updates are performed in Wireless Manager- Includes: ATW-DR3220LK receiver, short and long rack ear kit, power supply, antennas, front-mount antenna kitATW-DT3201 Transmitter Features- Rugged cH-style connector provides secure connection to lavalier mics, headworn mics, and cables with a cH-style screw-down 4-pin connector- Features external control buttons, mute switch, OLED display, and a SideTrack function that enables switching between multiple outputs- Powered by a custom-designed lithium-ion battery for best-in-class battery life and convenient charging in the ATW-CHG6 two-bay charging station (sold separately) or ATW-CHGA6 battery charger (included with ATW-DT3201DF2C)- Seven-color LED, along with seven physical color rings, make it easy to color code each channel- IR sync functionality enables easy synchronization with receiver- Best-in-class, all-metal construction- Includes: two ATW-DT3201 Body-pack transmitters, two ATW-CHGA6 battery chargers, two LI-220 rechargeable lithium-ion batteries, two ATW-TI10 color ring indicator kits, two AT831cH wireless cardioid condenser lavalier microphonesSpecifications:Overall SystemOperating Frequencies- DF2: 470.125 to 607.875 MHzModulation Mode- Standard: 8-PSK- HD mode: 16QAMOccupied Bandwidth- Standard: 192 kHz- HD mode: 96 kHzFrequency Response- Standard: 20 to 20,000 Hz- HD mode: 20 to 20,000 Hz- Depending on attached microphone element.Operating Range- 100 m (328)- Open range environment with no interfering signals.Dynamic Range- ATW-DT3201 (Mic input): 120 dB, A-weighted, typical- ATW-DT3201 (Inst. input): 109 dB, A-weighted, typical- ATW-DT3202: 120 dB, A-weighted, typical- ATW-DT3207: 120 dB, A-weighted, typicalTotal Harmonic Distortion- 0.1% or less (at 1 kHz, -20 dBFS)Maximum Simultaneous Use (recommended)- Standard: 17 channels / 6 MHz- Results may vary depending on the radio environment and usage conditions.Delay- Standard: 2.1 ms typ.- HD mode: 3.3 ms typ.Audio Sampling Rate- Standard: 48 kHz- HD mode: 48 kHzEncryption System- AES256Notes- For product improvement, the product is subject to modification without notice.
