Sound Devices' first miniature transmitter incorporates state-of-the-art features such as full remote control via the A20-Remote app, long range modulation, GainForward Architecture, SpectraBand's 470 MHz - 1525 MHz tuning range, internal 32-bit float recording, and more. The Sound Devices A20-Mini is fully compatible with the A20-RX and the A10-RX.
The A10/A20 Wireless System delivers the longest transmission distance of any system on the market. The state-of-the-art, 100% digital long-range modulation offers the same great audio quality (10 Hz - 20 kHz) as our Standard modulation scheme with a longer range for both line-of-sight and heavy multipath transmission.
SpectraBand technology delivers a tuning range of 470 - 1525 MHz in a single unit - an industry first. Experience ultimate flexibility as you find open spectrum away from the crowded UHF TV band.
