The MP573 is a two stages, single ended class A preamp, based on the design that was originally used in the Neve 1290/1073 modules, that has been adapted to the 500 series of API.

The SK25 and SK99 are discrete Op-Amps which are pin compatible with the API* 2520. They are low noise, high performance DOA's specially developed for audio applications.

The MP 512 is based on one discrete Op-Amp, one Cinemag input transformer and one Cinemag output transformer.

The MP 599 is based on one SK99 discrete Op-Amp, one Lundahl input transformer and one Lundahl output transformer.

The MP566 is a dual-triode vacuum tube circuit preamplifier based on a design that has been used in several famous devices from the 50's, which has been adapted to the '500' format of API*.

The MC624 is similar to the monitor section of a mixing desk: it lets you select one out of six stereo audio sources, adjust the level and route it to one of four monitor outputs.

The EQ573-II is an parametric equalizer based on the design that was originally used in the Neve 1073 and 1084 modules, that has been adapted to the '500' format of API*.

The CP5176 is a FET compressor based on the design that was originally used in the 1176 compressor, which has been adapted to the '500' format of API*.

The TS500 is an analog processor that recreates the sonic imprint of vintage tape recorders. It provides the roundness, the punch, the compression and the saturation of magnetic tape.

The SK501 is a single slot, 500 series compatible case and power supply.

The XT500 is an extension cable which lets you connect a 500 series module to your lunchbox while keeping it outside for easy setting or maintenance.

The LA502 is a soft knee, electro-optical compressor based on the LA2A/LA3A design, which we have adapted to the '500' series format of API*.
