Neve 8051 Surround Compressor
Made by hand, the Neve 8051 Surround Compressor is an analogue compressor 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.
