RF•STOP AC Power Filter

RF•STOP AC Power Filter

Regular price $295.00 Sale

An AC powered DAC requires power free of transients and RF noise—filtering is required well into the MHz range. For DAC's with an integrated switch-mode power supply, its worth doing the modification to change it to a linear (transformer-based) design. RF•STOP™ AC Filter adds proper RF noise filtering to the input AC mains. Power supplies with upgraded fuses or improved wiring offer only a nominal level of additional RF filtering. RF•STOP AC Filter uses a two-stage design with inductors of highly permeable core material for excellent attenuation of common-mode and normal-mode noise. Wideband filtering extends from 10kHz up to the critical RF frequency of 500MHz.

For best performance, locate RF•STOP AC Filter very close to the component AC input - ideally with an option short patch cable. Use RF•STOP on amplifiers and monitor speakers to prevent capacitive/inductive coupling of RF noise and conduction along galvanic signal paths to your DAC. AC inlet connection is IEC C14; outlet connection is IEC C13.
