AKG B29L phantom power supply makes the ideal accessory for powering MicroMic III Series condenser microphones. AKG B29L features an on/off switch and a status LED, plus a mic/line selector for matching the output level to the input of a connected mixer or recorder. B-29-L can be powered from a standard 9V battery, which will give up to 50 hours of use.
Two volume controls allow you to balance the levels of two connected microphones and a supplied clip makes it easy to attach AKG B 29 L to a belt or guitar strap.
