After extensive research and development, Sound Devices presents the A20-TX Digital Wireless Bodypack Transmitter, a versatile and innovative audio solution. This advanced device is designed to serve multiple purposes, making it an essential tool for audio professionals seeking flexibility and reliability. The A20-TX transmitter is compatible with a wide array of input sources, including two- or three-wire lavs, dynamic mics, phantom-powered condenser mics, guitars, balanced line-level sources, and even AES digital mics. This multipurpose input capability eliminates the need for additional transmitters, streamlining your audio setup and reducing the amount of equipment you need to carry or rent.One of the standout features of the A20-TX transmitter is its true balanced ultra-low-noise, high-headroom mic preamp. This industry-first feature, also found in our renowned 8-Series mixers, offers superior noise reduction, headroom, and sonic purity compared to the mic preamp in the original A10-TX transmitter.The A20-TX transmitter also boasts an impressive battery life of up to 12 hours. Its flexible powering scheme accommodates a variety of battery types, including standard alkaline or NiMh AA batteries, rechargeable Li-Ion batteries, rechargeable LiFePO4 batteries, or even USB battery packs.Equipped with Sound Devices' proprietary NexLink 2.4 GHz long-range wireless remote control technology, the A20-TX transmitter can be controlled and timecode synced from an A20-Nexus or A20-Nexus Go digital receiver, even over long distances and through Wi-Fi, Bluetooth, and other 2.4 GHz interference. The A20-TX transmitter also features Sound Devices' proprietary SpectraBand technology, enabling it to tune over a super wide frequency range of 169-1525 MHz. This broad range ensures maximum compatibility with other audio equipment and wireless systems.For applications requiring a user-actuated switch, the A20-TX transmitter includes the industry's first physically removable switch. Its large size, positive tactile operation, and magnetic activation provide users with ultimate confidence and reliability.The A20-TX transmitter's GainForward feature eliminates the need for gain setting on the transmitter. You can control your A20-TX transmitter's audio gain directly at the mixer's digital trim control or at the wireless receiver, ensuring optimal audio performance.Finally, the A20-TX transmitter's e-Paper Display allows for easy viewing of settings and menus, even in sunlight or when powered down. The screen's backlight turns on for easy visibility when you open the battery door, making it simple to change settings in the dark. In summary, the A20-TX Digital Wireless Bodypack Transmitter is a durable, high-quality, and reliable device that offers advanced features and innovative technology for all your audio transmission needs.
