7600 Input Module

Features
Uses API 2520 Op Amp Complete API Input Module Includes Mic Pre, EQ, Compressor, Sends, Busses and Solo Several Units can be Linked Together to Make a Console Links to the 7800 Master Control Module Panning, Mute Group, Insert functions Re-issue of the Original API 550A Equalizer All Inputs and Outputs on Rear Panel Three 7-segment LED VU diaplays Output Clips at +30 dBm
The API 7600 Input Module offer studios of all sizes a whole new range of options without sacrificing quality. Perfect for project studios who want high performance console sound, but have limited channel needs and/or budget availability, professional studios who may want to add more channels to their existing desk through the addition of a SIDE CAR, or custom Broadcasters who need a high quality 3 or 4 channel top of the line full-featured console, the API 7600 strip forms the basis of a build-as-you-need-it, high quality recording console.
The new API 7600 fits into one rack space unit. It includes a genuine API mic pre, a compressor and a real 550A EQ right out of the glory days of rock n roll. The 7600 mic pre is the same mic pre currently available in the 200 Series Legacy Console modules, the 212L. The EQ is AN EXACT reissue of the famed 550A, offering 3 bands of API EQ but with 7 frequency choices PER BAND. The compressor is the 225L, the same compressor found in the popular, all discrete Legacy console still in production. The 7600 is available either in a HORIZONTAL or VERTICAL panel configuration, the only difference being the legends on the panel. Complete with internal power supply, the 7600 strip is the basis for building a 4 channel, 8 channel or even 16 channel professional sounding API console. All the user needs is a rack. This allows a studio to design a custom side car console that can be used as extra inputs or as a portable floating console that can be moved from one control room to another, when needed. It can also be the basis for an extremely high quality 4-8+ custom console for remote recording applications, such as classical recordings or broadcast live remotes that require only a few channels. To complete the signal path, we are introducing the API 7800 Master Module containing Bus masters, Solo logic and control, TalkBack and Master VU metering, as well as a full featured Master Control Room section for speakers and tape playback.
