Charging stations, rechargeable batteries, power supplies and antenna cabling that keep wireless microphone inventories running: Sennheiser’s BA-series battery packs with the L70 and CHG2UK chargers, Shure’s SB904 battery and SBC networked docking chargers, plus NT-series power supplies and BNC-terminated antenna cable.

Rechargeable packs are model-specific, so match them exactly: the BA 70 serves EW-D and EW-DX transmitters, the BA 30 covers SpeechLine, D1 and AVX bodypacks, and the SB904 fits GLX-D+ systems. The same rule applies to power supplies, where each receiver generation has its own part number, something to confirm before show day rather than during it. For fixed installs and rental stock, networked docking chargers like the SBC220 standardise the end-of-night routine and take the guesswork out of battery condition. Antenna cabling should be 50 ohm coax with BNC terminations, kept as short as practical because UHF loss builds with every metre; the 15.2m UA850 covers the runs you cannot shorten.

Unsure which battery or PSU matches a given transmitter, send us the model code and we will confirm before you order.
