JMF Audio PCD 302. PCD 102.

JMF Audio PCD 302 and PCD 102, Orose® Silver and Black, final stage of manufacturing, December 2022. The PCD 302 and PCD 102 are mains filters that provide a cleaner power supply to the audio equipment for greatness in the musical rendering. The PCD 302 has been used by 2L to power their mobile recording equipment since 2016 and have participated to the production of numerous albums, among which several were nominated for the GRAMMY Awards.

Powering the audio equipment… Caring for the music…

For more than three decades, JMF Audio had focused on the amplification and the transport of the audio signal, building a reputation for a natural rendering of music among music lovers, audio enthusiasts and studio professionals. With time, questionings regarding the influence of the mains on the perceived sound quality became frequent. We therefore decided to study the subject, for our own sake, for our clients’ satisfaction, for the music.  We measured, analysed, listened, made correlations… Tackling power line issues along with ensuring musicality, the challenge was high…    
We now can state that as much optimized an audio system can be it will never reveal its full potential without a clean mains power supply. Following the success of the PC3 power cord for the significant sound quality improvement that comes along, JMF Audio brings a total answer: the PCD 302 power line filter and distributor, a world’s first concept. 
The exclusive bi-directional and independent filtering principle featured in the PCD 302 and PCD 102, suppresses power line disturbances coming from the outside as well as interactions between audio components. 
  • Dual mono concept for the PCD 302
  • Powered through attached JMF Audio PC3 cords
  • Phase detection on each input
  • Bi-directional JMF Audio BDF 223™ filtering
  • Hand crafted, hand wrapped, potted BDF 223™  filters
  • 10 filtered outputs of which 6 are totally independent for the PCD 302
  • Sequential power output to reduce in-rush currents on the mains with the PCD 302
  • A single front panel button to power-on and power-off the main power supply
  • Mounted on sub-chassis, acoustically floating, virtually immune to vibrations
  • Total power handling: up to 7kW depending on the model
  • Operation from 100 to 240V AC automatic

Elegant concept:

With a simple gesture, from its front panel button, the PCD 302 and the PCD 102 can start up and power down an entire JMF Audio setup, without risk of power line shutdown, without risk of “pop” in the speakers. The sequential output power-up of the PCD 302 ensures a spread of in-rush currents over time. For coherence, the PCD302 is built around the same chassis as the JMF Audio power amplifiers and the PCD 102 is built around the same chassis as the JMF Audio pre-amplifiers.

Simplicity of installation:

Two indicators on the rear panel light up to warn in case of phase reversal. The operation from 100 to 240V AC, without servicing, makes installation internationally easy and safe. Clear and extensive owner’s manual provided.

For the music:

A closer link to the artists, a more enveloping and contrasted rendering with wider sound-stage, fluidity, sweetness, fullness, deeper bass response. Definitely another Instrument for the music®.
