Sound Devices has released the A20 Battery Doubler for the A20-Mini Digital Wireless Transmitter. The unit replaces A20-Mini’s existing battery door, adding room for a second rechargeable NP-BX1 battery that runs in parallel with the first NP-BX1 battery. Once installed, the Battery Doubler increases the A20-Mini’s maximum run time to nine hours, while adding just 7mm to the thickness to its casing.

‘We’re always looking for ways to increase the capabilities of our A20 series wireless devices,’ says Sound Devices RF Applications Engineer, Gary Trenda. ‘Given the long hours and increasingly challenging RF production environments that our customers are finding themselves in, the A20 Battery Doubler is an essential upgrade that will keep the A20-Mini running with them no matter how long the job is.’

The A20-Mini Transmitter and A20-RX Wireless Receiver are designed to meet the demands of increasingly RF-heavy workloads for audio engineers worldwide. The key feature of the A20 series is proprietary SpectraBand technology (which offers a worldwide tuning range of 470MHz-1525MHz), SAW filtering and sonic and signal clarity. Initially designed with the needs of the film and television production spaces in mind, the A20 series is equally effective in broadcast, live event production and house of worship use.

‘Compact wireless devices that offer many channels and wide, usable tuning bands lend themselves to increasingly creative applications for wireless audio,’ says Sound Devices CEO, Matt Anderson. ‘As our customers continue to test the limits of what wireless technology can do, we will be right alongside them ensuring that our products continue to deliver under the toughest circumstances.’

The A20 Battery Doubler is available now for MSRP US$150.
