AMS NEVE 8851

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.

Each channel can be controlled from either Side Chain A or Side Chain B, and the six signal paths can be split between the two side chains in any format required. Each audio channel can be routed to either or both side chains; for example the Centre channel in a 5.1 mix may be compressed using Side Chain A but also input to Side Chain B to control compression of the Surround Channels.
