User manual NEVE 5043

[. . . ] INTRODUCTION Thank you for your purchase of the 5043 Duo Compressor Limiter. Everyone at Rupert Neve Designs hope you enjoy using this tool as much as we have enjoyed designing and building it. Please take note of the following list of safety concerns and power requirements before the use of this or any Portico SeriesTM product. Safety It's usual to provide a list of "do's and dont's" under this heading but mostly these amount to common sense issues.

"High Frequency Sound Above the Audible Range, Affects Brain Electric Activity and Sound Perception" Paper read at 91st. (1), Conclusion. 4 DESCRIPTION GENERAL DESCRIPTION The Rupert Neve Designs 5043 module is a half rack width, 1. 75" (1U) module in the now wellknown PorticoTM style. The 5043 is ideal for both tracking and mixing applications with selectable Mixing Buss or Line inputs. The 5043 is an ideal choice for either standalone operation, or forming the core of a larger mixing system. As with the entire PorticoTM range, the construction takes the form of a heavy and robust steel shell providing total magnetic screening and exceptional mechanical stability. The front panel is machined from a solid . 2" aluminum plate with a steel sub panel behind it. Alternative front panel layouts are available providing a choice of vertical or horizontal mounting for the 5043. When the horizontal front panel is chosen, a single 5043 can sit firmly on a bench or desktop on its detachable rubber feet. Two 5043's can be joined with the optional 5221-RM Horizontal Joining Kit, which can be mounted across a standard 19" rack. When the vertical option is chosen, up to eight 5043's can be mounted in the optional 5285-RM Rack-Mounting Frame that is equipped with guide rails. This leaves a 3" width that can be used to house a power supply or other master modules. The 5285-RM Rack-Mounting Frame also includes basic rear cable management, and optional blank panels are available to fill any unused spaces when the full complement of eight modules is not fitted. The PorticoTM 5043 embodies two independent Compressor-Limiters, "A" and "B". They can be used independently or connected in sequence to provide two separate control slopes. control circuits may be linked via a front panel push-button so that the level of each unit, "A" and "B", may be held in a constant relationship for stereo operation. Rear panel connections are provided to enable linking of multiple 5043s. The linking may also be extended to the former AMEK CIB and DMCL units. THE WAY THE 5043 WORKS A part of the audio signal is rectified and smoothed to produce a suitable control voltage for the V. C. A. If the response is too fast, low frequency signals will themselves, be "gain controlled"!If the response is too slow, the signal will overshoot and the first few cycles will not get compressed. The sonic quality of these amplifiers is such that, by providing galvanic isolation, simple single-sided circuit topology, and freedom from grounding problems, they are capable of enhancing the sonic quality of many signal sources, especially those of digital origin. [. . . ] The BUSS inputs are configured as balanced and floating inputs that, when fed from a source impedance of 10, 000 ohms, will produce unity gain, (Compressor-Limiter switched out) overall. Several modules within the PorticoTM Range are fitted with a "TO BUSS" switch. The output from this circuit is intended to provide an input to PorticoTM modules with Buss inputs. Any number of modules may be fed to the Buss Input to provide high performance mixing that is intended to provide sub group mixing in a console configuration. [. . . ]
