54F50 Compressor / Limiter - API 500 series format
The 54F50 is a Class A, compressor and limiter module which occupies three slots in a 500 series rack. Fully populated with Carnhill transformers to achieve its distinctive classic sound. This high-end hand-built British module provides an afforda..
The FET-type solution was first used for its application in the legendary UREI 1176 compressor from the 70s. The most important feature inspired by revision A is the input transformer used and pure class A output stage. The compressor is equipped with a relay bypass, 2:1 Ratio and Slam Mode accessib..
Designed to work in standard 500 racks.
The Action by Purple Audio 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 ALTER 500 is a FET compressor built in the 500 standard. The FET-type solution was used for the first its application in the legendary UREI 1176 compressor from the 70s. The ALTER is a single-channel unit with stepped input and output controls. The Ratio switch has six positions, including two a..
The Serpent Chimera is a faithful replication of the classic LA3A design, available for the first time in 500 series. Featuring an all discrete circuit design, class AB transistor output, true T4B optical cell, and transformer balanced input & output, the Chimera delivers that thick, rich, & smooth ..
The DOUBLEWIDE II is a single-channel compressor that installs into two slots of a standard 500 series rack yet it requires only 130-milliamps of current—just like the original Retro DOUBLEWIDE compressor. Also retained from the original are the gray painted front panel, high-quality US-made Simpson..
The first entry by ELI into the 500 series format, the DerrEsser is a multi function dynamic filtering device. Available in vertical or horizontal versions. A perfect fit for our EL500 powered rack. In its basic “DS” mode, it is an effective, level insensitive “de-esser” - a device that w..
The DerrEsser is a multi function dynamic filtering device, in an API 500 series module format. In its basic DS mode, the DerrEsser is an effective, level insensitive de-esser, which is a device that will adjust the high frequency gain on overly trebly or spiky vocal, or other source. By using a cro..
FALCON is a classic sounding tube compressor in a 500 series package.
FALCON features 3 attack and 3 release time settings, hard and soft knee choices for compression or limiting, two different audio path sounds, wet-dry mixing for parallel compression, and is linkable.
The audio path color is cha..
The IGS ONE LA 500 is an opto-compressor built for the 500 series format. This is the first high voltage vacuum tube 500 series module that is offered by IGS. It is powered with 250V DC from an on-board voltage converter, so it can be plugged into any 500 series rack equipped with a standard power s..
The PHOTON 500 is an optical compressor, based on technology from the 60's, first used in the early LA-2A limiters and later in the LA4. As an homage to these legendary products, we packed this technology in a 500-series module. The PHOTON 500 uses an opto-coupler, which introduces negative feedback..
The S-Type is a typical VCA compressor well known as the core of the legendary British sound. The heart of the compressor is the THAT integrated circuit instead of the now unavailable DBX. The analogue path is balanced with ultra-fast op-amps. This is the source of completely transparent sound. A mi..
