Rear Panel Functions

Unbalanced Input and Output

Unbalanced Input from preamplifier, accepts a standard unbalanced input (RCA). The input connection is the uppermost connector, indicated by red inner ring. Line Output to other amplifiers (e.g.bi-amping),accepts a standard unbalanced input (RCA). For more information on Line Input and Output specifications, please refer to Chapter 11.

Caution! Never apply signal to the Balanced and Unbalanced inputs simultaneously.

Balanced Input

Accepts a signal from a preamplifier with balanced outputs via high quality XLR connectors. The use of good quality balanced interconnects allows the input signal to be relatively immune to noise and external effects caused by the use of long interconnect cables, helps reduce hum loop noise and aids in the cancellation of distortion products.

The pin assignments of the balanced XLR input connector is as follows:

Pin 1: Signal ground

Pin 2: Signal + (non-inverting)

Pin 3: Signal – (inverting)

Shield ground: Chassis ground

10

For more information on line input specifications, please refer to Chapter 11.

Note: Please refer to the operating manual of your preamplifier to verify that the pin assignments of the balanced output connectors correspond to the SX60m balanced inputs. In the event that they are not compatible, the interconnecting cable will need to be altered to suit.

Balanced Output

Balanced Output to other amplifiers (e.g. bi-amping),accepts a standard balanced connector (XLR).

The pin assignments of the balanced XLR output connectors are as follows:

Pin 1: Signal ground

Pin 2: Signal + (non-inverting)

Pin 3: Signal – (inverting)

Shield ground: Chassis ground

For more information on line output specifications, please refer to Chapter 11.

Note: Please refer to the operating manual of your amplifier to verify that the pin assignments of the balanced input connectors correspond to the SX60m balanced outputs. In the event that they are not compatible, the interconnecting cable will need to be altered to suit.

5 Special Design Philosophies

Minimalist

Design

Perreaux 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 design, materials and manufacturing techniques has advanced in tandem with this. Today’s Perreaux range comes closer to fulfilling our shared vision than at any other time in the past.

The SX60m has been developed to meet customer demands for compact higher quality products. Careful attention has been taken throughout the development phase, not to make compromises that would degrade the high quality of reproduction that the unit is capable of delivering.

To follow is a discussion on some of Perreaux design philosophies that have been incorporated into the entire range.

Leading British architect, John Pawson, writes:

The Minimum can be defined as the perfection that an object achieves when it is no longer possible to improve it by subtraction. This is the quality that an object has when every component, every detail, and every junction has been reduced or condensed to the essentials. It is the result of the omission of the inessentials”.

Perreaux has historically embraced the minimalist ethic from an audio design perspective only. The concept of “less equating to more” has been at the heart of all Perreaux audio designs for more than a quarter of a century. Our current product offering takes the minimalist ethic to new levels by totally embracing the concept.

Minimalist Electronics

We wish to maximise the quality of your listening pleasure by keeping the componentry and signal path as uncluttered, short and clean possible. All components in the signal path, even those of the highest quality have an effect on the signal, thereby altering the quality of the reproduction in some way. Our aim is to recreate in its entirety, the original performance by not adding or subtracting anything, irrespective of the source.

13

Minimalist Aesthetics

Our products appeal to those who seek the ultimate in audio exclusivity, namely the perfect blend of “form and function”.

“Form and function” are both tough masters. We make no excuses for producing some of the most distinctive high-endaudio products on the planet. We let “form and function” blend together in perfect harmony. This surely is the essence of true minimalist utilisation.

Minimalism in a Wider Context

John Pawson writes:

Clearly simplicity has dimensions to it that go beyond the purely aesthetic: it can be seen as the reflection of some innate, inner quality, or the pursuit of philosophical or literary insight into the nature of harmony, reason, and truth”.

Special Design Features

Construction The SX60m is stylish and unobtrusive. The front panel is made from high quality solid 6.0mm (0.2”) thick aluminium extrusion featuring our trademark machined Perreaux logo and large volume control knob. These are finished in durable and stylish satin chrome finish electroplate. On/off status is provided via a discreet blue LED inset into the front panel. The chassis and cover are both manufactured from heavy gauge steel. No cover fixing screws are visible. These minimalist styling cues combine seamlessly to allow form and function to blend in harmony and are typical hallmarks of the Perreaux brand.

Circuit Topology

Finest The SX60m features a 98VA toroidal mains transformer directlyQuality soldered to the PCB, Wima and Elna capacitors, highest quality

Components Zobel network and customized internal heat sink solution. TheUsed PCB isdouble-sidedand constructed from the highest quality

Throughout fibreglass base stock featuring 2oz copper.

The Power Perreaux has specially developed a fully shielded 98VA internalSupply toroidal based power supply. No fewer than eight filter capacitors are coupled in parallel providing a total of 17,600uF of power supply smoothing, keeping ripple to a minimum. As a result the power supply is extremely rigid, capable of delivering instantaneous power requirements demanded by musical transients. The result is significantly improved dynamic

capabilities.

Simple Front panel features on/off LED indication. The rear panelcontrol comprises a mains input receptacle, allowing the cord set to befunctionality upgraded if desired, mains switch, high quality speaker binding posts, unbalanced (RCA) and balanced (XLR) line inputs and

Block Diagram

Ultra Short Careful attention has been paid to the signal path within theSignal path amplifier. It is ultra short, guarded by ground planes where necessary and carefully routed to avoid contamination from

power supply and high current bearing sections.

Input Stage Utilising a stable current source, along with accurate current mirroring circuitry, the input stage of the SX60m, in combination with the overall circuit topology, provides precise detail resolution and definitive sonic transparency.

PCB Layout Special attention has been lavished on the PCB layout to keep sensitive signal stages away from power supply and filtering circuitry. The super clean custom designed power supply is physically segregated from the rest of the sensitive electronics.

Care and Maintenance

Note:

Cover

Front Panel

Note:

Please switch the unit off and remove the cord set from the rear of the Amplifier before attempting to clean your SX60m in the manner described below.

Never apply liquid directly to the SX60m. Never use abrasives.

Never rub in a circular motion.

The cover features a durable high quality powder coat finish. To remove finger marks and dirt, lightly rub the surface with a soft cloth.

If the dirt is not removed, dip your cloth in a mild solution of soap and water, squeeze excess moisture from it and then gently reapply to the surface.

Stubborn dirt may be removed by the application of a small quantity of isopropyl alcohol, applied directly to the cleaning cloth only, and reworking the effected area.

The SX60m front panel features a high quality electroplate finish. Over time the surface may retain finger marks and may need to be cleaned to restore it to original condition.

Regular Cleaning

Gently wipe the front panel with a very clean cotton cloth. Wipe across the surface and never in a circular motion.

Removing Stubborn Marks

Only attempt this infrequently, as too regular or vigorous application may damage the surface.

Apply a small quantity of any car polish containing carnauba wax to a very clean cotton cloth.

The car polish must state “Safe for Clear Coats” as the polish will therefore contain the absolute minimum amount of abrasive compound.

Gently wipe over the front panel in lateral motion, allow to dry then gently wipe off with a very clean cotton cloth.
