    Comments about Sennheiser BA 30 Rechargeable Battery Pack for SK:

    I am a sound tech at a church that purchased a sennheiser digital mic for our pastor. We were having issues with interference from 2.4 ghz wifi and the mic transmitter would channel hop every few seconds. The BA30 battery pack is rated at 3.7 volts. We first tried rechargeable batteries but total voltage was ony 2.4. Then we tried akaline at 3.0 Volts but that is still .7 volts lower than the ,BA30 battery pack. Since using the BA30 pack the channel hopping has stopped and any interference is almost imperceptible to the untrained ear. I hope this helps.
