Rupert Neve Designs has introduced of the
Portico 543 Mono Compressor, which delivers unobtrusive, musical-sounding
dynamic control and brick-wall limiting found in the Portico 5043 module to
the 500 series format. The 543 features a fully controllable
compressor-limiter with feed-forward/feed-back modes, Peak/RMS detection and
a built-in sidechain high-pass filter. With an unrivaled heritage and a
tremendous feature set, the 543 yields a combination of rich warmth,
flexibility and precision that is sure to resonate in the ears of sound
engineers the world over.
Built around Mr. Rupert Neve's custom transformer designs, each 543 module
encompasses individually controllable threshold, attack, release, makeup
gain, ratio, sidechain HPF, Feed-forward/Feed-back selection and Peak/RMS
detection modes. With the compressor inactive, the 543 may be used as a
transformer-coupled, high-performance line amplifier. Two 543s may be linked
for stereo operation. The chassis is built to standard 500 series
specifications, with power and I/O provided by the rack.
One of the more unique features of the 543 is the new Peak/RMS mode also
found in the Portico II Channel. This switch allows the VCA (voltage control
amplifier) to respond to both RMS (Root Mean Square) and peak levels. RMS
circuits are considered to better mimic the way the ears perceive apparent
loudness, while peak circuits tend to directly respond to the waveform
voltage, which may be more of a concern for prevention of clipping and
maximizing levels. In this case, peak mode uses a combination of both
methods to get the best of both worlds, and avoids the drawbacks of each
method on its own.
The 543 also has the ability to switch between feed-forward and feed-back
modes. 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, feed-forward
detection was implemented on Mr. Rupert Neve's more modern designs. With the
unit's FF/FB switch, both classic and modern VCA responses are available. Pricing and Availability:
