Sound Devices Astral TX Digital Wireless Transmitter
A Kaleidoscope of Connectivity
Finding a tool that can serve multiple purposes is the goal of every audio professional. More flexible gear means less - less for you to carry in a bag or fit in a case, and less gear to rent for a gig. That's the philosophy behind the Astral TX digital wireless transmitter. Sound Devices engineered it to be compatible with more input sources than any other transmitter, including two- or three-wire lavs, dynamic mics, phantom-powered condenser mics, guitars, balanced line-level sources, and even AES digital mics. The Astral TX transmitter's multipurpose input saves you from having to pack or rent more transmitters.
True Balanced Input
The Sound Devices Astral TX transmitter includes an industry first: a full, true balanced ultra-low-noise, high-headroom mic preamp. In fact, this is the same preamp built into Sound Devices' vaunted 8-Series mixers. The A20-TX mic preamp is a big step up from the excellent mic preamp built into the original A10-TX transmitter in terms of noise, headroom, and sonic purity.
Excellent Battery Life
The Astral TX transmitter features battery life of up to 12 hours. Additionally, the Astral TX's flexible powering scheme allows the use of many battery types, including standard alkaline or NiMh AA batteries, rechargeable Li-Ion batteries, rechargeable LiFePO4 batteries, or even USB battery packs.
Advanced Features
The Astral TX transmitter boasts industry-leading features like Sound Devices' proprietary NexLink 2.4 GHz long-range wireless remote control technology that allows multiple Astral TX transmitters to be controlled and timecode synced dependably from an Astral ARX16 or Astral ARX8 digital receiver. NexLink works over long distances - even through Wi-Fi, Bluetooth, and other 2.4 GHz interference. The Astral TX transmitter's long-range modulation achieves excellent operational range. The Astral TX also includes Sound Devices' proprietary SpectraBand technology, which enables the Astral TX transmitter to tune over a super wide range of 169-1525 MHz.
Astral TX Switch
For the applications that call for a user-actuated switch, the Astral TX transmitter features the industry's first physically removable switch. Its large size, positive tactile operation, and magnetic activation give users ultimate confidence and reliability.
GainForward
WithGainForward, there is no gain setting on the transmitter! You control your Astral TX transmitter's audio gain, either directly at the mixer's digital trim control or at the wireless receiver, while maintaining the best audio performance in the industry. If the source is too soft or too loud, just use a downstream mixer's digital trim gain control to make adjustments. No more bothering the talent to make gain changes.
Powering Options
There's no need to stock special batteries for the Astral TX transmitter. It can work with any type of AA batteries, no matter the chemistry.
e-Paper Display
You can easily view settings and menus with the Astral TX transmitter's e-Paper Display, even in sunlight or when powered down and its batteries removed. Need to change a setting in the dark - Open the battery door and the screen's backlight turns on for easy visibility.
