AMS Neve 8051
5.1 surround compressor/limiter with six transformer balanced audio paths, complemented by two side chains and a key input
Based on six 2254 compression circuits - using the same feedback topology as our legendary 33609 stereo compressor - the 8051 delivers the famous Neve sound in spades. Flexible side chain routing, trimming and filtering make this a powerful and responsive tool for surround mixing and mastering.
