Up for sale is the legendary API 7600, a full-featured, discrete 1U console input channel strip.

Built around API’s proprietary 2520 op-amps and transformer-balanced circuitry, this single rack unit compresses an entire API Legacy console channel into 1U of space.

It features three of API’s most iconic processing circuits:

1. 212L Mic Preamplifier: Fast, punchy, and aggressive—the quintessential classic API sound.
   
2. 550A 3-Band EQ: The exact reissue of the classic discrete 3-band EQ with proportional Q.
   
3. 225L Feedback/Feed-Forward Compressor: Smooth VCA dynamic control with selectable knee and "Old/New" feedback detector modes.
   

This unit is in excellent physical and operational condition. It has been kept in a climate-controlled environment with minimal rack wear. Every rotary switch, potentiometer, button, and LED meter functions 100% as intended, delivering that signature forward midrange, fast transient response, and explosive headroom API is famous for.

Key Features & Capabilities:

• Full Rear Patching Facilities: Direct inputs and outputs for every section (Mic Pre, EQ, Dynamics), allowing you to run each processor completely independently or break into the signal chain with external gear.
  
• Integrated Routing & Bussing: Features 4 aux sends, 4 main bus assigns, panning, mute, solo, and stereo bus output for console/DSM system setups.
  
• Compressor Linking: Stereo link capabilities with second API 7600 or 225L units.
  
• High-Visibility Metering: Three 7-segment LED VU displays for visual signal management.
