HistoryThe 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.
TodayThe latest evolution of the RM 58 retains the same Class A audio circuit path and the FET gain reduction method. The new housing can be used on a desk or floor and is convenient to use in modern recording or performance situations. The overall performance has also been improved and both professional +4dBu and semi-pro -10dBu operating levels are catered for. These new improvements allow the RM 58 to be used in new situations where a rack mounted unit would not be a good choice.
Digital FriendlyThe use of a good limiter to control peaks effectively in real time before you go into the digital domain is the best way forward to record a great sound. Using limiter plug-ins after the fact will simply not do the job as the peaks have already been recorded. This means that the main part of the sound does not have as much resolution or bandwidth as may be possible to give the best sound.
The updated RM 58 has been designed to perform this new task with ease and bring a new dimension to digital recordings.
