Rega Elex MK4 + Monitor Audio Gold 50 4G 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.

Gold 50

The sculpted low-diffraction cabinet of the Gold 50 houses a single 5.5" RST bass driver and C-CAM ribbon.

The bass driver exhibits the low frequency extension and power handling of a much larger transducer while the excellent C-CAM ribbon soars beyond conventional tweeter domes to a stratospheric 60 kHz. Consequently the Gold 50 combines the frequency range of the finest studio monitors with dynamics that defy its modest dimensions.

Optional, dedicated floor stands are available, which can be filled to provide the ultimate foundation for the best possible sound quality.

This product is now available to use with home theatre design software, The Cinema Designer. Read more.

Technology

• C-CAM (Ceramic-Coated Aluminium/Magnesium) ribbon transducer design – providing extension to a class leading 60 KHz
• HiVe II port technology for better transient response and tighter bass
• New C-CAM RST (Rigid Surface Technology) bass/mid-range driver
• Single bolt through driver fixings for improved bracing, rigidity and driver/baffle de-coupling
• Die-cast alloy terminal panel arrangement with high quality bi-wire terminals and high end spade type link cables
• Pureflow Silver internal cabling
• Selected premium quality wood veneer or high gloss lacquer finishes
• Rigid 20 mm MDF construction throughout, employing radial and cross-bracing techniques for high rigidity resulting in low cabinet colouration
• Invisible magnetic grille fixing provides clean visual styling when used with the grille off.
