  1. questionWhat is the PC-1 rectifier and conditioner?
    The Jeff Rowland Design PC-1 is an advanced external power rectifier and conditioner based on the same Active Power Factor Correction [PFC) technology incorporated in JRDG reference amplifiers such as the Model 625 stereo power amplifier and the Continuum 500 integrated amplifier. PC-1 has been ...
  2. questionWhat are the salient features of the PC-1 active power correction rectifier and conditioner?
    The PC-1 design and construction reflects the unsurpassed Jeff Rowland attention to superior quality and detail: A high speed switch in the PC-1 circuit extracts energy at 100 KHz from an inductor during the entire cycle of the AC sinusoid. Ensuing DC Energy is then filtered through a capacitor ...
  3. questionWhat are the sonic benefits of powering a compatible JRDG component through a PC-1 rectifier and conditioner?
    Quite simply, the PFC-based PC-1 rectifier and conditioner turns compatible JRDG switch mode power amplifiers into even more emotionally compelling instruments of music reproduction. As the PFC-based PC-1 all but eliminates any hash and residual ripples from the input current, the connected ampl ...
  4. questionIs PC1 compatible with every JRDG preamplifier?
    No. Only the Capri preamplifier is universally compatible with PC-1, regardless of local mains voltage. COnversely, Rowland preamplifiers that incorporate some form of passive power factor correction, such as Criterion and Corus, are not compatible with PC-1. Please note that no classic Rowla ...
  5. questionWhich JRDG products are compatible with the PC-1 rectifier and conditioner?
    Certain JRDG components, equipped with universal voltage auto-sensing and auto-ranging switching power supplies, can be connected directly to a PC-1 without any modifications. Namely: Model 102 stereo amplifier. Capri preamplifier.Certain other components, equipped with single voltage switchin ...
  6. questionCan a single PC-1 be connected to a combination of Capri preamplifier and Model 102 stereo power amplifier?
    Yes, a single PC-1 PFC rectifier and conditioner can be connected to a Model 102 and Capri pair through a custom “Y” power ‘pigtail’ available from authorized JRDG dealers, or from the JRDG factory.
  7. questionCan a single PC-1 be connected to a pair of Model 501 monoblock amplifiers?
    Yes, a single PC-1 PFC rectifier can be connected to a pair of Model 501 monoblock power amplifiers through a custom “Y” power ‘pigtail’ available from authorized JRDG dealers or from the JRDG factory.
  8. questionCan a single PC-1 be connected to a pair of Model 201 monoblock amplifiers?
    A single PC-1 PFC rectifier can be connected to a pair of Model 201 monoblock amplifiers through a custom “Y” power ‘pigtail’ available from authorized JRDG dealers, or from the JRDG factory. However, a dedicated 750W PC-1 unit connected to each Model 201 monoblock will f ...
  9. questionWhere can I buy a “Y” power pigtail for a PC-1, so I can connect it to 2 devices at the same time?
    The “Y” power ‘pigtail’ cord is used to connect a single PC-1 to 2 separate components. It is available from JRDG. It can be ordered from authorized JRDG dealers, or directly from JRDG.
  10. questionWhat will happen if I connect a PC-1 to a component compatible with PC-1 only at 240V, without changing the component’s voltage and fuses from 100V to 240V operations?
    Do not do it. You will blow a fuse in your component, or you may cause much more serious damage to it. Any damage resulting from PC-1 misuse is not covered by any JRDG warranty, and will be repaired at owner's expense.
  11. questionIs PC-1 compatible with stereo components from other manufacturers?
    PC-1 converts any 100V AC to 175V DC, and any 240V AC to 385V DC. Some 3rd party components equipped with universal auto-sensing and auto-ranging switching power supplies might work with the DC voltages supplied by PC-1. However any experiment will be at the user’s own risk. JRDG strongly ...
  12. questionWhat happens if I connect a PC-1 to a completely incompatible stereo component?
    Do not do it! If you connect PC-1 to any incompatible device, you will blow a fuse in your component, or you may cause even much more serious damage to it. Any damage resulting from PC-1 misuse is not covered by JRDG warranty and will be repaired at owner's expense.
  13. questionI have a component not listed as compatible with PC-1. I connected it to a PC-1. Now the component no longer works. What can I do?
    You may have blown a fuse in your component, or you may have caused more serious damage. Immediately power down your entire system, then disconnect PC-1 from the affected component. Check and replace any external fuses. If your component is still inoperative, it will need to be repaired. Contac ...
  14. questionI have damaged a component by connecting it inappropriately to a PC-1. Does the PC-1 warranty cover this damage?
    No, if you misuse a PC-1 by not following the directions and warnings clearly printed on the plasticized card shipped by JRDG with each PC-1, Any damage resulting from PC-1 misuse, either to the PC-1 itself, or to any other component in the system, is not covered by any JRDG warranty. Any such ...
  15. questionWhere can I obtain a “Y” power pigtail to connect the PC-1 to a pair of compatible components?
    JRDG ships a standard ‘pigtail’ cord with each PC-1 PFC rectifier for connecting it to a single audio component. However, “Y” pigtails to connect a single PC-1 to 2 components simultaneously can be obtained from authorized JRDG dealers or from the JRDG Factory.
  16. questionWhere can I obtain an upgraded power pigtail for the PC-1?
    JRDG ships a standard ‘pigtail’ cord with the PC-1 PFC rectifier for connecting it to a single audio component. However, JRDG can supply PC-1 pigtail cord specifications to customers interested in sourcing upgraded power ‘pigtails’, or directly to specialty power cord man ...
  17. questionWhat are the technical specifications of the PC-1 dedicated ‘pigtail’ power cord?
    The PC-1 power pigtail contains 3 conducting wires (positive, negative, and ground). It is terminated with a 15A male IEC connector at one end, and with an IEC 320 shrouded male connector at the other end.
  18. questionDoes the JRDG warranty cover damage caused by connecting a PC-1 to the Criterion and Corus preamplifiers?
    No, PC-1 is neither compatible with Criterion nor with Corus. if you misuse a PC-1 by not following the directions and warnings clearly printed on the plasticized card shipped by JRDG with each PC-1, including connecting it to Criterion or Corus, Any damage resulting from PC-1 misuse, either to ...
  19. questionWhy Is the PC-1 PFC rectifier NOT compatible with the Criterion and Corus preamplifier?
    The Criterion and Corus preamplifiers incorporate a passive Power Factor Correction (PFC) circuit in their high speed switch mode power supply (SMPS). The AC input of these preamplifiers is not compatible with the 384V DC output voltage of the external PC-1 rectifier. The external PC-1 unit is t ...
  20. questionCan a PC-1 rectifier and conditioner be connected to the Criterion and Corus preamplifiers?
    Do not do it! The external PC-1 rectifier and conditioner is not compatible with the Criterion and Corus preamplifiers.
