Roger Mayer RM58 Limiter

Dual Channel FET Limiter with 456 HD Analogue Tape Simulator


The Roger Mayer RM58 is a dual channel FET limiter with 456 HD technology, based on Roger Mayer’s original limiter used in Olympic Studios Record Plant, Electric Lady and many more iconic studios around the world.

The Roger Mayer RM58 boasts a unique FET Gain reduction circuit working in a feed-forward mode that controls both positive and negative peaks. This results in a stable stereo centre image even with a vast amount of gain reduction. Furthermore, it uses a real-time dynamic gain reduction method that works constantly, providing truly natural and musical sounding results. As a result of the constant and dynamic nature of the processor, there are no controls for ratios.

With a discrete Class A low-noise circuit path and an uncompromising approach to design, the RM 58 provides unparalleled transparency and extended frequency response all the way up to 100kHz. Class A output is also employed, providing ultra-low output impedance, ideal to work with professional equipment and modern recording systems.

In addition to the limiter, the RM 58 boasts Roger Mayer’s highly regarded 456 HD technology which adds the harmonic enhancement of Studer A80 with Ampex 456 tapes. Trim controls are also provided for DAW level matching.

The original Roger Mayer RM 58 was used in recording studios at the mastering stage before cutting vinyl. Its superior sound is finally available again and adapted to modern recording workflows while keeping all the quality of uncompromising vintage recording equipment.
