The RM 58 is still regarded today by many leading producers as a Holy Grail piece of vintage analogue equipment and was first manufactured in New York by Roger Mayer in 1970. It was an evolution from the RM 57 Limiter with the RM 58 providing greater headroom and more user friendly front panel controls. The audio circuit path was of a Class A discrete design only using the best available components and featured a proprietary FET gain reduction circuit. The RM 58 quickly became popular with all the top studios in the US including: Record Plant, Hit Factory, Electric Lady, Atlantic Records, Elektra Records, Columbia Records, A&R Studios.
It was also used to master records with special 4 channels versions for the cutting rooms of many leading record labels. It has been used on so many famous records I would not know where to begin. Technically the design was very advanced for it's time and today it's performance still compares very favourably to newer designs. The circuit path is extremely clean and transparent with an extended frequency response to 100Khz. The output is Class A unbalanced with a very low output impedance and we have never found any need to balance the output as the low impedance ensures a hum free interface. This method together with a Class A circuit audio path provides the ultimate transparency for the audio. It is the way the unit controls the peaks that makes this unit different from others and remains very natural sounding even with large amounts of gain reduction.
Although this unit is pre owned it is in near new condition, with no noteable signs of use.
