AMS NEVE 2254/R

Esteemed Neve Diode-Bridge Compression

Designed in 1969, the original Neve® 2254 mono Limiter/Compressor unit quickly became a legend. Forty years on, the 2254’s successor, the Neve 2254/R mono limiter/compressor represents another milestone.

From the first Diode-bridge compressor, the 2252, through to the early cubic 2254 modules, Neve® compressors have been held in very high regard as often treasured studio essentials. Now, the 2254/R takes this treasured circuit design into the 21st century with a modern 19? rack format for seamless integration into your studio racks.
