Installation & Ventilation - Rega ELEX MK4 User Manual

INTRODUCTION
Thank you for purchasing the Rega Elex MK4. The Elex MK4 is a stereo integrated amplifier designed to deliver the purest musical
performance. Housed in a brand new custom designed case to match the rest of the Rega range, the new MK4 builds on previous Rega
designs by using our multi-award-winning Class A/B power amplifier circuit to deliver a powerful 72W per channel into 8Ω loads. This
power is provided by a quiet multi-stage linear supply whilst supply rails for digital and analogue sections are galvanically isolated.
The Elex MK4 can drive difficult loudspeakers with ease and will integrate perfectly into any audio system by offering a wide range of
connectivity options. In addition to line, digital, and a high-quality moving magnet (MM) phono input, you will also find Pre-Out, Record Out
functionality and a high-performance headphone output.
As you would expect, special attention has been paid to the selection of key audio components. Discrete circuitry, high-quality relays,
polypropene capacitors, and Sanken output transistors are used throughout the design.
The galvanically/optically isolated digital inputs utilise a Wolfson S/PDIF receiver IC to provide exceptional detail and clarity from any
connected source. Output is provided by a Wolfson DAC and Rega designed discrete line-driver circuit.
The new Elex MK4 calls upon decades of award-winning experience in amplifier and digital circuit design which culminates in a perfectly
engineered balance of reliability, connectivity and above all, accurate music reproduction.
INSTALLATION
INSTALLATION & VENTILATION
The Elex MK4 amplifier will work well on most surfaces, such as a shelf or a table, provided there is sufficient air around the case to
prevent overheating. If using a turntable, avoid magnetic interference by positioning the amplifier as far away from the turntable as the
tonearm lead will allow. If possible, place it to the left of the turntable. Keep other equipment away from the amplifier. Due to the layout of
Rega's amplifier circuit designs, they are virtually insusceptible to electromagnetic interference, and by virtue of a full metal enclosure, emit
practically no electromagnetic radiation. However, placing any electronic equipment such as sensitive phono amplifiers close together may
impair the performance of one or both items. Never stack other hi-fi components on top of the Elex MK4.
WARNING: The mains supply cord functions as a mains disconnect device.
The socket outlet should therefore be located near the equipment and be easily accessible.
The heat produced by the Elex MK4 amplifier is dispersed via the heat sinks located on either side of the product. Please ensure
adequate space around the exterior of the product to allow for sufficient airflow, otherwise overheating may result. If the Elex MK4 is driven
at high volume for a long period, it may become quite warm. This is entirely acceptable if there is sufficient ventilation, and the amplifier
will continue to work normally without damage. If the amplifier is overdriven, it may overheat, however the Elex MK4 contains thermal
protection that will disable the output or the power to the product temporarily. Once the product has cooled, it will automatically resume
normal operation. Never place the amplifier on carpets, rugs, or bedding.
WARNING: Case sides may become very hot!
