Page 5: Power Requirements
Meter Power Requirements Each Shelford 5051 is fitted for use with a specialized stand alone, multi-unit power supply modules. The power supplies feature a proprietary 4 pin polarized input for +24 and -24V DC power input, and come in 5-way and 25-way options. The 5-way is a brick &... - Page 6 considered above our hearing range had a measurable effect on listener’s electroencephalo-grams. Kunchur describes several demonstrations that have shown that our hearing is capable of approximately twice the timing resolution than a limit of 20 kHz might imply (F=1/T or T=1/F). His peer reviewed papers demonstrated that we can hear timing resolution at approximately with 5 microsecond resolution (20 kHz implies a 9 microsecond temporal resolution, while a CD at 44.1k sample rate has a best-case temporal resolution of 23 microseconds).
- Page 7 “signature” of its own. This leaves the designer free to use amplifier and transformer combinations that are well proven and produce the desired sonic quality. All Rupert Neve Designs modules use input and output transformers and class-A amplifiers to produce the musical “signature” for which they are known. These are factors that enable the 5051 to work unobtrusively within the context of a very high quality audio chain.
- Page 8 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.
- Page 9 extraordinary performance and musicality expected from a Rupert Neve design. The EQ certainly invokes similarities sound-wise with some of Rupert’s classic EQ designs from the seventies. The 5051 repeats history in using a custom tapped inductor and carefully selected capacitor values to form the mid range equalizer band.
- Page 10 Unlike other modules for the 5088, the Shelford 5051 requires its own standalone power supply to operate. The power supply features proprietary 4-pin polarized outputs at +24 and -24V DC, and will power up to twenty-five 5051 modules. 5051 Features LINE 1 / LINE 2 Allows you to have two sources pre-patched into the 5051.
- Page 11 reduce the signal level at the source to minimize the potential for distortion when any of the 3 bands are boosted significantly. EQ PRE / POST Switches the order of the equalizer and compressor sections. With the button out, the equalizer is before the compressor, which means that moderate changes to the EQ settings may require some adjustment of the compressor threshold to maintain a similar amount of compression, or make up gain to maintain a target output level.
- Page 12 material from excessively controlling the compressor. With mixes or wide spectrum sounds, there is often significant amounts of low frequency energy that can cause occasional deep compression, yet it is often the mid frequency sounds that are associated with apparent loudness and the zone that needs compression. The S/C HPF is designed for those situations and 250 Hz is well suited for both vocals and mixes and most other dynamic wide spectrum sounds.
- Page 13 the output rise by 1 dB implying 9 dB of compression, 2:1 will cause the output to increase 5 of those initial 10 dB suggesting 5 dB of reduction. Some engineers relate ratios of 20:1 and higher with limiting, however technically traditional limiting also requires very fast attack times to respond to transients and prevent signals from actually going above a certain level.

device described above. The S/C insert return may also be used as a key input. For example, an engineer might wish to patch in a kick drum to control the compression happening on a bass guitar being run through the 5051. IMPORTANT NOTE: The S/C insert return is a half-normal connection, meaning that if a plug is inserted into the jack, it will interrupt the S/C signal path, and whatever signal is present on the plug will now be the controlling the compressor side-chain,... - Page 15 from 20 Hz to 20 kHz is +25 dBu.
