The Rupert Neve Designs Portico 543 Mono Compressor 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 Neves 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 Purple Audio Action features a constant impedance 600 ohm input attenuator feeding the input transformer, just like our MC77 units. This makes the input more resistant to overload by hot signals. After the input transformer, the signal is attenuated by the same gain reduction FET as in the MC77. The attenuated signal is buffered by our class A KDJ3 opamp, which feeds the output fader. Lastly, our class AB KDJ4 output opamp drives our custom hexafilar nickel and steel output transformer. The total gain (with no attenuation) is 45dB, just like the MC77. The Purple Audio Action Features: - Input attenuator feeding input transformer - Output level control - Input and output tricolor LED metering - Eight LED GR metering - Five ratios including "All buttons in" mode - Attack and Release controls - True Relay Bypass - Stereo Linking - Compression on/off switch - Discrete signal path - Over Current Resettable Fused (prevents any module problem from affecting your rack) - ROHS - Lead Free Specifications: - Total Gain: 45dBu - Ratios: 4:1, 8:1, 12:1, 20:1, :1 ("All buttons in") - Attack time: Continuously Variable from over 800 microseconds to 20 microseconds - Release time: Continuously Variable from over 1.1 seconds to 50 milliseconds - Input impedance: 600 ohms - Output impedance: 600 ohms - Current consumption: 90ma

New Klark Teknik | High-Performance 4-Channel Creative Quad Compressor, DN540 with Balanced Outputs and Advanced Envelope Generator w/ Manual Controls
Brand: Klark Teknik
Compressors were originally devised to reduce the dynamic range of audio signals. To do this they use gain modification that makes adjustments to signal levels automatically, dependant on the level and dynamic of the signal itself, and upon the character and control settings of the particular compressor unit.
Throughout the history of dynamics processing many different types of compressor have been produced using many different types of gain technology. Each type has a distinctive sound. Users have found many applications which benefit from these often unintentional compression audio artifacts, taking the use of compressors far beyond simple dynamic range reduction, sometimes even generating the complete reverse; dynamic enhancement. It is with these creative applications in mind, that the DN540 has been designed to offer a latency-free, comprehensive and compact dynamics processing package.
With its unique presence feature the DN540 will be especially useful on vocals to eliminate the "pumping" effects of spill and to add "air" to the sound without introducing noise.

The Portico 543 from Rupert Neve Designs is a fully controllable compressor-limiter featuring feed-forward / feedback modes, Peak / RMS detection and a built in side chain high pass filter. There's nothing like a Rupert Neve design matched with a great set of features and the 543 combines that amazing warmth, precision and flexibility that only the Neve name could bring you.Built around Mr. Rupert Neve s custom transformer designs, each 543 module encompasses individually controllable threshold, attack, release, makeup gain, ratio, side chain HPF, Feed-Forward / Feed-back selection and Peak/RMS detection modes.

The chassis is built to standard 500 series specifications, with power and I/O provided by the rack.Different Control TypesIn order to control gain, a VCA or Voltage Controlled Amplifier (or Attenuator) is used. There are many types of Voltage Control, including the use of tubes, discrete and integrated solid state circuits and naturally non-linear devices, each one having its characteristic behavior that reflects sonically on the final performance, and gives it a character or signature that can be musically attractive or not! Since the VCA's really have no signature of its own, this compressor has very accurate, low noise, low distortion A part of the audio signal is rectified and smoothed to produce a suitable control voltage for the VCA which has to respond very quickly and have low distortion. 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 speed and accuracy of the response, known as the attack , and the time frame that gain remains under the initial control, known as release or recovery and plays a large part in the way a compresso
