Rolls PB224

Perfect for any condenser microphone, the new PB224 powers even the high-current draw microphones. The unit features a complete redesign in the voltage supply circuits, offering a rock solid 48 volts of clean phantom power. The 224 now sports a vastly improved molded plastic battery compartment for the two 9 Volt alkaline batteries, however it will still operate on the Rolls PS27 AC adapter.
