Sound Devices A20-RX-SL 2-Channel True Diversity Receiver with SpectraBand Technology

Share

NOTE: This listing is for the Sound Devices A20-RX Receiver with no bottom adapter.

Experience ultimate flexibility as you find open spectrum away from the crowded UHF TV band. The Sound Devices A20-RX 2-Channel True Diversity Receiver features industry-exclusive SpectraBand technology which delivers a tuning range of 470 - 1525 MHz in a single unit. Superior low-loss, brick-wall SAW filters deliver excellent performance in noisy RF environments, while the AutoAssign feature makes frequency selection and setting quick and easy.

Sound Devices A20-RX Receiver - Features:

• SpectraBand Technology: compatible with the A20-Mini from 470 MHz - 1525 MHz and all tuning ranges of the A10-TX.
• Advanced Digital True Diversity topology uses two complete RF receivers for each of the two channels, with four RF receivers in total.
• SuperSlot compatible with the SL-2 and 8-Series mixer-recorders.
• State-of-the-art 100% digital long-range modulation delivers the longest transmission distance of any digital system on the market.¹
• GainForward Architecture compatible with the A20-Mini. Set the Mini’s gain levels via trim control (with an 8-Series) or at the A20-RX (for other mixers).
• Full 10 Hz - 20 kHz audio bandwidth; 100% digital RF modulation and transmission.
• Excellent immunity from nearby IFB or camera hop transmitters without the need for external filters or extra cabling.
• Maximum connectivity: SuperSlot, XLR, and TA3 backplates, A-RXMON headphone amp, and A-15PIN two-channel AES Sony camera slot adapter.
• Analog line-level or AES digital audio output.

With SpectraBand Technology, you won't need to purchase another receiver dedicated to a specific country or frequency band. SpectraBand gives you access to nearly twice the frequencies available with other systems worldwide – almost 2600 available channels.

The A20-RX's AutoAssign scans a tuning band and selects available frequencies for you—perfect for any fast-paced shoot. Meanwhile, brick-wall SAW filters eliminate out-of-band interference so you can get the best RF performance possible. Enjoy immunity from nearby IFB or camera hop transmitters without the need for external filters or extra cabling.
