REGA ELEX MK4 INTEGRATED AMPLIFIER LAUNCHED

The Rega Elex MK4 is a stereo integrated amplifier, housed in a brand-new case to match the rest of the Rega range.

The Rega Elex MK4 builds on previous Rega designs using their class A/B power amplifier circuit which delivers 72W per channel into 8Ω loads (90W into 6Ω). The new amp directly replaces the now discontinued Rega Elex- R model.

REGA ELEX MK4 AMPLIFICATION CIRCUIT

The Rega engineers have re-engineered the entire ELEX circuit board to optimise performance. MK4 builds on previous Rega designs by using the brand’s Class A/B power amplifier circuit. 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 Rega DAC-R circuit. The galvanically/optically isolated digital inputs utilise a Wolfson S/PDIF receiver IC. Output is provided by a Wolfson DAC and Rega designed discrete line-driver circuit. The Rega 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.

REGA ELEX MK4 INTEGRATED AMPLIFIER MM PHONO STAGE

A high performance Rega designed integrated moving magnet (MM) phono stage is 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

The headphone socket on the Elex MK4 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.
