Pair of Compressor / Limiter and Class A mic/line amp & EQ derived from the legendary Neve 1073 and 2254, in API VPR 10 slot psu with mono/stereo switch

 

The Audio Maintenance ez1073-500 is a mono, Class A, mic pre-amp, line amp and EQ/Filter module inspired by original 1073 units. It comes in dual-slot  500 Series format.

Fully populated with Carnhill transformers and inductors to achieve its distinctive classic sound, this high-end hand-built British module  offers exceptional quality and a great sounding preamp and EQ for your 500 Series rack. Not surprising when you consider that it is derived from the legendary Neve 1073, but surprising when you read the comments by users that rate it alongside the original units.

 

The Audio Maintenance 54F50 is a Class A, hand-built, British compressor and limiter module derived from the Neve 2254 design. It occupies three slots in a 500 series rack.

Fully populated with Carnhill transformers to achieve its distinctive classic sound the AML 54F50 is built to the highest spec with only the finest components used in the manufacture.

Capable of offering the sound and performance previously only offered in vintage console units now long defunct and largely unavailable, the 54F50 from Audio Maintenance is built to an uncompromisingly high standard and as such represents great value for money.
