Alctron Rack3 500 Series Rack with MP73A, CP52A and EQ75A - 500 Series

Alctron Rack3 500 Series Rack with MP73A, CP52A and EQ75A - 500 Series
The perfect solution for the studio producer, musician or recording engineer. The Alctron 500 series mic preamplifier, compressor and parametric EQ together with the 3-slot rack power supply provides everything you need for your quality signal workflow.

Alctron Rack3 500 Series Rack
The Rack3 is a three module rackmount power supply, in a single RU 19" rack, designed to combine signal processor modules. The feed switch on the rear panel allows you connecting one module into the nest to set up elaborate channel strips without having to hard patch modules using cables. The aluminium heavy-duty metal shell make the product stable and durable. And what’s more, the whole construction design is on the base of a standard rack. The Alctron MPS-1 is a linear power supply. Ideal to power the Rack3, the Alctron 3-slot 500 Series rack. It provides four times the current necessary to power a preamp, and can power up to 3x Rack3 units.

MP73A 500 Series Microphone Preamplifier
The MP73a is a 500 Series microphone preamp. It is a one-channel vintage style microphone, line and instrument preamplifier. Highly inspired by a certain 1073 preamp. Its sound character described as warm and punchy, with a very musical character giving a lovely top. These classic characteristics have been heard on countless recordings through the years and it is a versatile sound that works very well on most sound sources and in most genres. This is a preamp suitable for most types of audio sources and is also excellent as DI.

CP52A 500 Series Mono Compressor
The CP52a is a 500 series module with a fully variable, full function compressor. There is a "clip" LED to tell you when your signal is getting too hot. The "fast/slow" switch allows for a quick and easy choice of attack and release settings. The threshold, ratio, and output gain are fully variable. There is also a HPF at 100Hz, a polarity switch, bypass, and 48v on board. 

EQ75A 500 Series Parametric EQ
The EQ75a adopts class-A circuitry, whilst additional frequencies have been added to the mid and high-frequency sections. With only discrete components included in the signal’s path, the EQ75a has a warm, punchy, sweet and musical characteristic. Modeled after the legendary NEVE 1073 EQ module, the EQ75a is very versatile and will work on most sound sources in almost any genre. The output line adopts A type transformer push-pull circuit. It eliminates crossover distortion to keep the original sound quality and its wide output load applying to various devices. EQ75a features with independent input and output connectors.
