    200 Watts is twice as loud as 20 Watts not ten times as loud. Due to the protection functionality designed into the R200i, this tradition no longer needs to be adhered to. The R200i is suitable to use with speakers that have power handling greater than it’s continuous rated output and in fact, would greatly benefit from speakers that can handle the output peaks the R200i can deliver.

  • Page 52: The Power Mosfet

    The Power MOSFET Today with the vast number of technical achievements occurring around the world, many discoveries are overshadowed or obscured by some that may appear more important to the general media. One such discovery of importance, to the audiophile at least, is that of the power MOSFET device.

  • Page 53: Audio Applications

    operations. This means that complementary power MOSFETs – P and N channel – can be used in an audio output stage providing greater linearity of operation than can be achieved with valves. In addition, further advantages over the valve include their much smaller size, no filaments and greater reliability with reduced vulnerability to physical damage.

  • Page 54: High Frequency Response

    High Probably, from the sonic quality point of view, the most important Frequency improvement is the power MOSFETs vastly superior high frequency Response response. A large proportion of the power transistors used in modern hi-fi amplifiers start to show a decline in efficiency from 10kHz upwards. The efficiency of the power MOSFET does not start to decline until about 2MHz and is only down 3dB at 30MHz.

  • Page 55: Frequently Asked Questions

    How often do you introduce new products? As satisfied Perreaux owners are well aware, we are never in any great hurry to bring new products to the marketplace. Refinement of musical performance is not a process to be rushed or neatly scheduled to coincide with important events.
  • Page 56 Can I change the voltage of my Perreaux if I move to another country? The end user is unable to do this, however if the need arises, the Perreaux distributor could undertake this work. You should expect to pay for this service.
  • Page 57 Which speakers do you recommend for your amplifiers? Because Perreaux amplification is designed to be utterly neutral with no sonic character of its own, any high quality equally neutral speaker that is agreeable to your room, musical tastes and general sonic preferences will be a good match.

  • Page 58: Care And Maintenance

    Care and Maintenance The R200i has been designed to provide many years of trouble free enjoyment. It’s important to keep the exterior of the unit clean and to periodically ensure that the air-cooling grills remain clear from obstruction. Note: Please place the unit in standby and remove the cord set from the rear of the amplifier before attempting to clean your R200i in the manner described below.

  • Page 59: Faultfinding Your R200I

    Alternatively, careful designs must be employed to negate these effects on low-level signal equipment (such as the R200i onboard phono module option). Another good practice to adopt is to keep all signal leads away from power leads.

  • Page 60: Identifying And Isolating Problems

    The entire hi-fi system must be connected to the same mains/line power outlet. This will ensure that each piece of the system shares the same earth or ground. This rule applies to all installations of all brands of equipment. A preamplifier or power amplifier may be operated from an extension cord plugged into the same mains/line outlet.
