  3. questionWhat are the benefits of the efficient design of the Model 201 monoblock power amplifier?
    An extremely compact footprint sporting a width of only 8.4 inches, a depth of 11.5 inches, and a height of mere 2.6 inches, combined with energy efficient green technologies that ensure cool operation and high reliability, make the elegant Model 201 monoblock amplifier ideal for every listening ...
  4. questionWhat are the salient technical features of the Model 201 monoblock power amplifier?
    As typical for JRDG products, the entire chassis of the Model 201 compact monoblock amplifier is milled from a solid, massive block of 6061 aircraft-grade aluminum to provide a vibration-free and EMI resistant enclosure for its sensitive audio circuitry. The chassis is sealed to prevent dust ...
  5. questionIs the Model 201 monoblock power amplifier a green product, and why is it important?
    Jeff Rowland is committed to help manage responsibly the finite energy resources of our planet. This is one of the many reasons why he has embraced the green technologies of switch mode power supplies and class D ICEpower in the Model 201 compact monoblock power amplifier. The Model 201 enjoys a ...
  6. questionWhy does the 201 monoblock power amplifier employ a highly regulated switch mode power supply?
    The advanced and high speed switch mode power supply of the Model 201 monoblock power amplifier is enhanced by voltage regulation. It is nimbler, faster, more responsive, and lighter than traditional linear or toroidal power supplies. It contributes to the superior dynamics and agility of the ...
  7. questionWhy does the Model 201 monoblock amplifier feature a fully balanced output stage?
    The 201 is fully balanced in its output stage to maximize speaker control and authority, staging and imaging, nuance and resolution, while halving the levels of output currents. The uncompromising balanced design of the Model 201 monoblock amplifier extends to its output stages. The ICEpower 50 ...
  8. questionIs the Model 201 monoblock power amplifier compatible with high efficiency speakers?
    The Model 201 monoblock power amplifier supports a maximum speaker impedance load of 16 Ohms, which makes it compatible with most high efficiency speakers. Please note that Model 201 is not compatible with extreme speakers whose input impedance rises above 16 Ohms. If Model 201 were connected t ...
  9. questionIs the Model 201 monoblock power amplifier compatible with low efficiency speakers?
    The Model 201 power amplifier supports a minimum speaker impedance load of 2 Ohms. The amplifier has a damping factor of 1000. This makes it compatible with many low efficiency speakers. Please note that Model 201 is not compatible with speakers whose impedance load dips below 2 Ohms. If Model ...
  10. questionCan the Model 201 monoblock power amplifier drive any speaker load?
    The Model 201 monoblock power amplifier supports speaker impedance loads between 2 and 16 Ohms. This makes it compatible with a large number of speakers on the market, ranging from high efficiency speakers to moderately sized low and complex impedance speakers. However, the Model 201 is not com ...
  11. questionCan the 201 drive bi-wired speakers?
    The Model 201 has 1 single binding post. For speakers that support bi-wiring, remove the jumpers connecting the 2 sets of binding posts together on the loudspeaker. Connect 2 speaker wires to the Model 201 binding post. Connect one pair of wires to the high frequency terminal of the loudspeaker ...
  12. questionWhat is the estimated break-in time for the 201 monoblock power amplifier?
    A new 201 monoblock power amplifier reaches its full performance potential after an extended break-in period which may protract for over 1200 hours of playing time. Sophisticated amplifiers like the 201, which operate at low temperatures and contain switch mode power supplies, input transformers ...
  13. questionShould the Model 201 monoblock power amplifier be left powered on at all times?
    As the Model 201 monoblock amplifier draws only 9 Watts when idling, it is recommended that it be left powered up even after its initial break-in process is complete. This ensures that whenever music playback resumes, the 201 achieves peak performance within a few minutes of playing time. Whene ...
  14. questionDoes an external power conditioner benefit the sound of the Model 201 compact monoblock power amplifier?
    A pair of Model 201 monoblock amplifiers benefit from connection to twin external JRDG PC-1 active power factor correction (PFC rectifier and conditioner units much more than from connection to any third party external power conditioner. The JRDG PC-1 was expressly designed by Jeff Rowland to fu ...
  15. questionDoes the Model 201 monoblock power amplifier support speaker wires terminated with banana plugs and bare wires?
    The patented Cardas binding posts on the Model 201 monoblock amplifier accept only spade terminations for loudspeaker cables. Banana plugs or bare wire connections can be used with an optional clamp available from authorized JRDG Dealers and from the JRDG factory.
  16. questionWhere is the serial number of the Model 201 monoblock power amplifier located?
    The serial number of the Model 201 monoblock power amplifier is located on the rear panel of the chassis. It starts with the letters “MB”. The serial number must be included with any correspondence with the factory.
  17. questionDoes the Model 201 monoblock power amplifier accept single ended RCA inputs?
    Single ended RCA sources can be connected to the XLR balanced input connectors of the Model 201 monoblock power amplifier through dedicated XLR to RCA adapters available from authorized JRDG dealers or from the JRDG factory.
