Serial Number The serial number is unique to y our E160. Please record this number and store i t in a safe place. For any service related enquiry , please be prepared to quote the product serial [...]

13 AC Mains Input and Fu se AC Mains In put An I EC-standard mains input is provided at the rear of the unit. The AC cord se t is removable, allowing y ou to upgrade to a cord set of y our preference. Caution! Prior to connecti on to the AC mains, please check the voltage label on the rear panel to ensure that your u nit conforms to the power suppl[...]

14 Speaker Output Terminals The E160 is equipped with one set of gold plated output terminals per channel. All terminals are clearly marke d and colour c oded RED Positive (+) a n d BL ACK Negative (-). This polarity must be observed when connectin g loudspeakers, i.e. positive terminal of the E160 to the positive terminal of the loudspeaker and ne[...]

15 5 5 5 5 Special Design Philosophies Perrea ux has been designing and manufacturing only the highest quality audio componentry for more than a quarter of a century . Technology has continued to evolve rapidly over that time and our knowledge and application of desig n, materials and manufacturing techniques has advanced in tandem with this. Today[...]

16 “Form and function” are both tough masters. That is why our amplifier hea t sinks are not hidden, but instead feature prominently in all our designs. W e 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 perfec t harmony . This surely is the esse[...]

17 6 6 6 6 Special Design Features Rugged Build Qual ity Mechanical strength has been a hallmark of Perreaux products since th e company first started production back in 1974. The concept behind the phy sica l design and construction is that each structural member should contribute to bot h rigidity and performance. Stiff Power Supply The E160 inco[...]

18 Earth Isolati on Switch The toggle switch on the rear of the E160 allows the internal circuitry to b e isolated from the mains earth, whilst still maintaining an earth connection to th e chassis. This ensures the pot entially fatal practi ce of using an AC cord-set wit h no earth connection, to alleviate sy stem hum, is not required. Highest Qua[...]

19 7 7 7 7 Maximising System Potential Interconnects and Speaker Cables An often-ignored area in high fidelity sy stems is the cabling connecting th e various components. I nterconnect leads should be high quality cable wit h substantial terminations. Gold plate is inherently resistant to corrosion, and a n excellent conductor. The presence of corr[...]

20 Note: 160 Watts is twice as loud as 16 Watts, not ten ti mes as loud. Perrea ux equipment is designed with substantial headr oom built in – that is, th e reserve necessary to reproduce musical peaks without clipping. Final Thoughts High fidelity sy stems are an investment deserving of careful thoug ht an d personal time. Your preferenc es, pri[...]

21 8 8 8 8 The Power MOSFET Today with the vast number of technical achievements occurring around th e world, many discoveries are overshadowed or obscured by some that ma y 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 MOSF ET The field effect trans[...]

Audi o Applications When used in an audio power amplifier, th e advantages of the power MOSFE T over the power transistor are much more difficult to describe and would requir e grea ter complexity tha n can be gone into he re. However[...]

23 High Frequency Response Probably , from the sonic quality point of view, the most important impr ovemen t is the power MOSFETs vastly superior high frequency response. A larg e proportion of the power transistors used in modern hi-fi amplifiers start to sho w a decline in efficiency from 10kHz upwards. The efficiency of the powe r MOSFET does no[...]
