The device is supplied with a clip that fastens it to a belt or guitar strap. It uses a single 9-volt battery, providing an average life of 50 hours. The output of the B 29 L can be switched either to mic or line output level, depending on the downstream requirement. Both inputs to the B 29 L are mini-XLR-F, and the output is a standard XLR-M. The B 29 L effectively makes one output out of two. It is indispensible with small mixers, where it can expand the number of available inputs. In addition, many small mixers do not have phantom powering. The B 29 L offers an attractive solution for this problem.
