Rega Elex MK4 High Performance Stereo Integrated Amp / DAC

Description

ELEX MK4

The Elex MK4 is a high performance stereo integrated
amplifier designed to deliver the purest musical performance. Housed in a brand
new case to match the rest of the Rega range, the MK4 builds on previous Rega
designs using our multi-award winning class A/B power amplifier circuit which
delivers an impressive 72W per channel into 8Ω loads (90W into 6Ω). New rear
connectivity options are available with the Elex MK4 now including a Rega DAC
circuit with two digital inputs and a high quality headphone output conveniently
located on the front panel.

Bringing your music to life

The Elex MK4 is capable of driving difficult loudspeakers
with ease and will integrate perfectly into any audio system by offering a
wider range of connectivity options. In addition to the line level, digital
inputs and a high quality moving magnet phono stage,  you will also find
Pre-out and Record Out functionality alongside a headphone output. Special
attention has been paid to the selection of key audio components. Discrete
circuitry, high quality relays, polypropylene capacitors and Sanken output
transistors are used throughout the design.

AMPLIFICATION CIRCUIT

Our engineers have re-engineered the entire ELEX circuit
board to optimize performance. 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.

DIGITAL CIRCUIT / DAC

The DAC is based closely on the hugely successful Rega DAC-R
circuit. The galvanically/optically isolated digital inputs utilize 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. Our engineers have worked exceptionally hard to ensure
that the analogue side of the circuit is not affected in any way by the
introduction of digital inputs.

MM PHONO STAGE

A high performance Rega designed integrated moving magnet
(MM) phono stage is carefully built into the circuit. The RIAA equalization has
been split into two stages to minimize interaction. Polyester capacitors have
been used in the signal path and polypropylene capacitors are used in the RIAA
equalization circuits.

HEADPHONE OUTPUT

We have taken great care to incorporate the headphone socket
on the Elex MK4. This has been configured such that the speaker switching is
performed by the output mute relay to avoid obstructing the signal path
ensuring no loss of performance when it is not in use.

CUSTOM CASE

The new custom case design and construction brings the Elex
MK4 inline with the rest of the Rega range and provides improved heat
dissipation by using the entire case as an ultra efficient heat sink.

PROTECTION

The Elex MK4 includes Thermal Cut-Out, short circuit
protection and DC protection to prevent the risk of damage from excess heat,
excessive currents or short circuits.
