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 award-winning Class A/B power amplifier circuitry delivering an impressive 72W per channel into 8Ω loads (90W into 6Ω).
New rear connectivity options are available with the Elex MK4 which now includes a Rega DAC circuit with two digital inputs and a high quality headphone output conveniently located on the front panel.
AMPLIFICATION CIRCUIT
Our engineers have redesigned the entire ELEX circuitry to optimise performance. The MK4 builds on previous Rega designs by using our award-winning Class A/B power amplifier circuitry to deliver a powerful 72W per channel into 8Ω loads. This power is provided by a quiet multi-stage linear power supply, whilst the power rails for the digital and analogue sections are galvanically isolated.
DIGITAL CIRCUIT / DAC
The DAC is closely based on the highly successful Rega DAC-R circuit. The galvanically/optically isolated digital inputs use a Wolfson S/PDIF receiver IC to provide exceptional detail and clarity from any connected source. The output is provided by a Wolfson DAC and Rega designed discrete line driver circuit. Our engineers have worked 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 integrated into the circuit. The RIAA equalisation 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 equalisation circuitry.
HEADPHONE OUTPUT
We have taken great care to incorporate the headphone socket on the Elex MK4. This has been configured so that speaker switching is performed by the output mute relay to avoid obstructing the signal path ensuring no loss of performance when not in use.
CUSTOM CASE
The new custom case design and construction brings the Elex MK4 in line 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-off, short circuit protection and DC protection to prevent the risk of damage due to excessive heat, excessive currents or short circuits.
