Rega Elex MK4 + Polk Audio Reserve R200 Hi-Fi System Package

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.

PRODUCT DETAILS

AMPLIFICATION CIRCUIT

Our engineers have re-engineered the entire ELEX circuit board to optimise 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 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. 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 minimise 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.

RESERVE R200

LARGE BOOKSHELF SPEAKER

As the larger bookshelf speaker in the series, the R200 excels in delivering extra bass power thanks to its 6.5” turbine cone woofer and larger cabinetry. Perfect for listening in a stereo pair, as part of a front stage, or as surround components in a larger system.

FLAGSHIP SOUND

WHAT BETTER SOUNDS LIKE

Inheriting best-in-class technologies from our flagship Legend series of loudspeakers, the Polk Reserve series helps teach you what better sounds like.

AMAZING SOUND AND ELEGANCE

With understated elegance, the Reserve line has a minimalist design with universal appeal. Inheriting Polk’s flagship transducer array, the R200 produces exceptional sound that rivals competitor speakers that sell for twice the price.

SIT RIGHT EVERYWHERE

PINNACLE RING RADIATOR TWEETER

The Pinnacle Ring Radiator Tweeter’s distinctive pointed shape guides the dispersion of high frequency sounds around a room. This innovation widens the sweet spot and allows you freedom to enjoy your music and movies wherever you choose to sit.

STRENGTH IN MOTION

TURBINE CONE WOOFER

Our pioneering turbine design delivers a significant increase in cone rigidity without increasing mass. This innovation means the woofer can move with increased accuracy and speed to deliver enhanced sound resolution, enabling you to experience a breathtaking level of detail in your music and movies.

PURITY OF SOUND

X-PORT

Polk's proprietary X-Port eliminates unwanted noise created as air moves in and out of the speaker cabinet port at high-speeds. This ensures a rich and detailed listening experience with tight distortion-free bass and a clean midrange.

FORM AND FUNCTION

EXCEPTIONAL CABINETRY

Reserve’s sleek cabinetry hides a world of audio innovation. Cabinets are carefully cross-braced to best eliminate unwanted interior resonances. Rounded exterior corners help disperse sound broadly around the room with minimal diffraction, creating an open sound stage.

HI-RES AUDIO CERTIFIED

Your sound is only as good as your source. With Hi-Res Audio certification, the Polk Reserve R200 bookshelf speaker delivers clear and detailed high-end response. Female vocals are particularly smooth and detailed without coloration. Plus, a minimum support of 40kHz perfectly reproduces the latest Hi-Res Audio files with improved audio extension.

ERTIFIABLY EXCELLENT
