Audio Maintenance 54F50

The Audio Maintenance 54F50 is a 3-slot 500 Series Class A hand-built British compressor/limiter derived from the Neve 2254 design.

Carnhill transformers used throughout, the Audio Maintenance 54F50 is built to the highest spec with only the finest components used in the manufacture. Capable of offering the sound and performance of the undoubted classic from which it is derived, the 54F50 from Audio Maintenance is built to an uncompromisingly high standard and as such represents great value for money.

With such care and attention to the details, the 54F50 is the perfect way to control the dynamics of your music and at the same time take the revered compression and limiting capabilities previously only offered in console units now long defunct and largely unavailable - not to say unaffordable as well, in many cases.

By making and sourcing parts for old equipment, as well as producing DIY kits and hardware, Audio Maintenance has gone out to uphold the values and standards that have made the original equipment so collectible today - now with the Audio Maintenance 54F50 you can own a future classic.
