Why Choose WBS?

Whenever I need to buy new kit this is the place to go. Wendy and her team have excellent knowledge of the equipment they supply, access to information from manufacturers about the kit and an attitude to genuine customer service that is not often found in today's globalised corporate world. I have dealt with all the main UK broadcast suppliers and buying from Wendy's is by far the best experience.

A20-RX-SL Digital Wireless Receiver

Experience ultimate flexibility as you find open spectrum away from the crowded UHF TV band. The A20-RX two 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.

  • 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 (coming soon) 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.

 

Auto Assign

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.

SpectraBand

SpectraBand is a brand-new technology which gives the A20-RX receiver and A20-Mini transmitter an unprecedented tuning range: 470 MHz - 1525 MHz. With SpectraBand, 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-Mini will receive a free firmware upgrade to enable SpectraBand.

Brick-wall filtering

The A20-RX's SAW filters eliminate out-of-band interference so you can get the best RF performance possible. Enjoy immunity from strong interfering signals (for example, a local DTV transmitter) or other transmitters close to the receiver (IFBs, 2-way radios, camera hops) without the need for external filters or extra cabling. The A20-RX's filters (yellow) are compared to two leading competitor wireless systems below (blue and green).
