The ATW-DR3220LK is an Audio-Technica LINK-enabled 2-channel receiver for the D50 digital UHF wireless system. This 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.Main Features:Audio-Technica LINK-enabled, 2-channel, half-rack receiver for the D50 digital UHF wireless systemFull 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 environmentsSwitchable between normal mode (Antenna Combining Diversity) and robust mode (MRC True Diversity), which offers superior RF stabilityUser 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 environmentsOnboard DSP offers high-pass filter, 4-band EQ, and compressor settings for each channelSupports AES256 encryption for superior securityEquipped with a network port for monitoring and device configuration via Wireless ManagerReceiver can be powered by included AC adapter or PoE+; PoE+ also provides redundancy to keep the receiver powered if AC drops outReceiver can be set to mixed output in situations where input channels are limitedSpectrum analysis (accessible via receivers front-panel display and/or Wireless Manager software) and IR sync functionality make setup easyWireless Managers system management tools include those to configure detailed EQ and COMP settings, and an advanced walk test for visual confirmation of multiple RF conditionsMultipoint 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 signalIncluded 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 spaceTAA-compliant (U.S.); Radio Equipment Directive (RED) cybersecurity-compliant (EU)Firmware updates are performed in Wireless ManagerIncludes: ATW-DR3220LK receiver, short and long rack ear kit, power supply, antennas, front-mount antenna kitSpecifications:Overall SystemOperating Frequencies- DF2: 470.125 to 607.875 MHz- DF3: 470.125 to 693.875 MHz- EF3: 580.000 to 693.875 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, 22 channels / 8 MHz- HD mode: 47 channels / 6 MHz, 63 channels / 8 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.
