Product Description
Audio-Technica ATW-R1440 System 20 PRO 4-Channel Digital Wireless Microphone Receiver (2.4 GHz)
Overview
The ATW-R1440 System 20 PRO from Audio-Technica is a 4-channel half-rack wireless receiver that is easily mounted in portable flight cases or permanent installations. When combined with a System 20 PRO bodypack transmitter and microphone or handheld mic/transmitter (both available separately), the system is well suited for educational facilities, conference rooms, houses of worship, broadcast studios, and other small- to mid-sized venues.
Versatile 4-Channel Receiver
- The flexible ATW-R1440 offers two operational modes, depending on your needs. Standard mode provides 2 microphone channels at a latency of 2.8ms, while HD (High Density) mode delivers 4 mic channels at a latency of 6.7ms.
- The chassis' front-panel OLED screen provides visual status information including RF signal level and the transmitter's battery life.
- A System ID number display indicates which transmitter is associated with a given receiver.
- The rear panel provides 4 balanced XLR output connectors for compatibility with a wide range of pro audio gear.
- The receiver module can be removed from the chassis and mounted up to 328' away and connected via Ethernet cable for better antenna reception when necessary.
- A 1/4"-20 thread allows for mounting the receiver module to a bracket, stand, and other fixture. The unit can also be permanently wall mounted using the included receiver unit holder.
- The durable half-rack receiver chassis houses a modular receiver unit and can be mounted alone using the included mounting brackets and screws. Two chassis can be mounted side-by-side using the included joining plate, allowing eight wireless mic channels (in HD mode) to occupy a single 19" rackspace for a compact multichannel installation.
- Up to five chassis can be linked using RJ12 cables, creating a stable environment in which up to 20 wireless mics are operating simultaneously, with all receiving, transmitting, and frequency allocation coordinated to prevent audio dropouts.
Clear Digital Audio that's Easy to Set Up and Operate
Digital Audio Quality
- The System 20 PRO offers full-bandwidth, 24-bit/48 kHz digital audio with none of the audio artifacts associated with analog companding.
Automatic Frequency Selection
- While in use, the system continually monitors activity in the 2.4 GHz Wi-Fi range and automatically switches to a clean frequency to avoid interference if necessary.
Pairing Multiple Transmitters
- Each receiver channel can be paired with up to four transmitters, allowing users to instantly switch between different transmitter configurations. This is useful in situations when you have multiple speakers, one after another, and you need to have them miked up and ready to go. All you'll have to do is turn one transmitter off and the next one on.
Three Levels of Diversity Assurance to Avoid Dropouts
Triple Diversity Reception Maximizes Wireless Signal Integrity
- Space Diversity: the receiver compares the signal showing up at its two antennas and chooses the strongest one.
- Time Diversity: the transmitter sends the digital signal in two imperceptibly different time slots and compares the two.
- Frequency Diversity: the digital audio is sent over two different frequencies at the same time and the system chooses the cleaner one.
For optimal performance, users are encouraged to maintain as direct a line of sight as possible between the transmitter and receiver.
2.4 GHz Wi-Fi Band
- Unlike traditional analog wireless systems, the System 20 PRO operates in the 2.4 GHz ISM band, away from interruptions and dropouts caused by TV and radio channel interference.
