    We maintain the human-link throughout, from design and construction, through to the ultimate test, your music, your system, your ears. Because we too listen to our products, we know that with your Perreaux you will discover many more of the musical secrets we strive to reveal.

  • Page 5: Important Safety Instructions

    The E160i should not be used near water, for example near a bathtub, kitchen sink, in a wet basement, near a swimming pool, etc. The E160i should be rack mounted only in a heavy-duty rack or stand that is recommended for audio equipment use.
  • Page 6 DO NOT attempt to repair the E160i. In the event of a problem, please contact your Perreaux dealer. DO NOT operate this product in an explosive atmosphere. Caution! The E160i is a convection-cooled amplifier. The finned outer heat sinks may become very hot when delivering high volume levels – to avoid...

Unpacking Inspect both ends of the cardboard box and open at the end without the Procedure central staple by slitting the reinforced tape at either side.
  • Page 9 Please do not mount the E160i directly onto carpeted surfaces. As a “rule of thumb”, allow 80-100mm (3-4 inches) around all sides of the product and mount the E160i on a flat surface, ensuring that the unit has adequate access to free flowing air.

  • Page 10: Instant Install

    After checking the supply voltage compatibility with the voltage rating on the E160i rear panel, insert the power cord-set supplied into the rear of the unit and into the wall. Switch on the socket at the wall and power up the E160i using the switch on the front panel.
  • Page 11 Increase the volume Slowly increase the volume control of the E160i to achieve a comfortable listening level. CONGRATULATIONS! Now that you have achieved your first objective, sit back, relax and please read the rest of the manual at your own pace, in your favourite armchair, whilst sipping a hot cup of coffee.

    Depress this switch to turn power ON. Mute relay circuitry is employed in the E160i so output is muted momentarily after the power switch is actuated. Depress the switch again to turn the unit off, at which time the outputs will be disconnected.

    Today’s Perreaux range comes closer to fulfilling our shared vision than at any other time in the past.
  • Page 20 “Form and function” are both tough masters. That is why our amplifier heat sinks are not hidden, but instead feature prominently in all our designs. We make no excuses for producing some of the most distinctive high-end audio products on the planet. We let “form and function” blend together in perfect harmony.

  • Page 21: Special Design Features

    Since power supply leads radiate at signal frequencies, all wiring is carefully loomed to minimise this effect. Hybrid Class The bi-polar transistors used in the E160i are run in Class A mode. This avoids A/AB the crossover notch distortion and the resulting odd-order harmonics present, to some degree, in all other classes of operation.
  • Page 22 Earth The toggle switch on the rear of the E160i allows the internal circuitry to be Isolation isolated from the mains earth, whilst still maintaining an earth connection to the Switch chassis. This ensures the potentially fatal practice of using an AC cord-set with no earth connection, to alleviate system hum, is not required.

    Bi-amping can achieve greater control, dynamics and resolution than if you try to run everything from a single stereo amplifier. Positioning Positioning of your source equipment (tuner, video, disc, tape, record, decks) is Ancillary important.
  • Page 24 Note: 160 Watts is twice as loud as 16 Watts, not ten times as loud. Perreaux equipment is designed with substantial headroom built in – that is, the reserve necessary to reproduce musical peaks without clipping. Final High fidelity systems are an investment deserving of careful thought and Thoughts personal time.

    9 9 9 9 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. The MOSFET The field effect transistor (FET) and then the MOSFET transistor have been around for a number of years, but only as a small signal-handling device, mostly...

Audio When used in an audio power amplifier, the advantages of the power MOSFET Applications over the power transistor are much more difficult to describe and would require greater complexity than can be gone into here.
  • Page 27 High Probably, from the sonic quality point of view, the most important improvement Frequency is the power MOSFETs vastly superior high frequency response. A large Response 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 28: Care And Maintenance

    The E160i 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 switch the unit off and remove the cord-set from the rear of the amplifier before attempting to clean your E160i in the manner described below.

    Perreaux products used with equipment manufactured by other manufacturers may cause an earth loop situation, but Perreaux products used with other Perreaux products will not cause an earth loop situation provided the following precautions are observed: The entire hi-fi system must be connected to the same mains/line power outlet.
  • Page 32 Check that the entire system is connected in the proper manner and that the mains/line supply is connected and switched on. For clarity during this section, we have labeled one loudspeaker ‘A’ and the other loudspeaker ‘B’. In this example, loudspeaker ‘A’ appears faulty. Initial system connections SOURCE E160i...
