is known as a “feed-back” compressor. The two compression characteristics are quite
different, with both the attack and recovery ramps are changed. Almost all of Mr.
Rupert Neve’s earlier designs were “feed-back”.
The way in which these modes change the dynamic performance can be seen in the
above graph, but the more interesting effects are noted by listening .“Feed-Back”
produces a sweeter, warmer sound but is not as accurate if you need to protect a
transmitter, for example.
5051 Design Notes
The Shelford 5051 represents Rupert’s latest addition to the 5088 family. Comprised
of a new inductor EQ circuit with a heritage going back decades, and a compressor
with elements from the Portico II: Master Buss Processor, the 5051 can be configured
within a 5088 console to deliver exceptional tonal and dynamic control on each
channel.
Traditional transformer coupled inputs and outputs are used for both technical
performance reasons and optimum musical reproduction. The primary signal path
uses Class A gain blocks; using as few of these as possible to get the job done. The
input circuit uses one gain stage, as does the line driver output. The compressor
introduces one stage, the EQ introduces two stages, plus one more if the 18
dB / octave high pass filter is engaged. By combining this minimalisitic design
aesthetics with class-A gain blocks and custom transformers, the 5051 provides the
