Overview
The RC300 unit isolates, regulates and reshapes the mains via a choke-capacitor circuit. It boasts a 3% variation at the output at rated power for a 15% variation on the mains input. When under loaded the regulation is better still and the sonic improvements are remarkable.
The RC300 also offers considerable protection from large spikes and brown outs. A fused IEC power inlet is provided and six high quality surface mounted power outlets.
The RC-300 is designed to address small signal retrieval.
