The Rupert Neve Design Portico 5043 Limiter/Compressor Duo features fully controllable dual mono or stereo operation plus innovative feedforward/feedback detection switching and yields a combination of rich warmth, flexibility and precision that is sure to resonate in the ears of sound engineers the world over.
FEEDFORWARD AND FEEDBACK DETECTION
Perhaps the most significant aspect of the Portico 5043 is the ability to switch between feedforward and feedback detection. In most of Mr. Rupert Neve’s earliest designs, feedback detection — controlling the VCA with a rectified voltage from the unit’s output — was intrinsic to the musical dynamic response. However, the very nature of a feedback compressor limits the attack time of the compression circuit. To offer faster, more technically accurate response times, feedforward detection was implemented on all of Mr. Rupert Neve’s more modern designs.
INDEPENDENT AND LINKED OPERATION
Each channel of the 5043 encompasses individually controllable threshold, makeup gain from -6 dB to +20 dB, ratio and VCA detection mode (feedforward/feedback). The channels may be used independently or connected in sequence to provide two separate control slopes on a single source. The D.C. control circuits may be linked via a front panel push-button so that the level of each channel may be held in a constant relationship for stereo operation. With the compressor inactive, the 5043 may be used as a transformer-coupled, high-performance line amplifier.
CONNECTIVTY
Rear panel connections are provided to enable the linking of multiple Portico 5043s. The 5043 can link both internal control lines or multiple additional 5043s, enabling one of them to serve as “master.” When either the buss or line level input is selected, custom-designed transformers couple the input and output to create a true floating ground, ensuring compatibility with modules outside of the Portico Range, and imparting the rich warmth that is so revered in Mr. Rupert Neve’s classic designs.
