Classic tone & dynamics control for the 5088.
The 5051 combines a three-band Inductor EQ based on Rupert’s vintage designs with the power & flexibility of the Portico II Compressor. Utilizing a fully-discrete class-A signal path and custom audio transformers and inductors, the 5051 delivers all the performance and musicality expected from a Rupert Neve design.
