Up for sale is a premium 4-channel API 512c 500-Series microphone preamplifier package, completely housed in a rugged BAE 6-slot chassis with its dedicated external power supply. Purchased brand new and recently decommissioned from active service in a pro studio, this bundle is in excellent condition. Combining four legendary API modules with BAE's world-class over-engineered power filtering, this setup delivers the ultimate explosive punch, fast transient response, and aggressive mid-forward bite that has defined American rock and pop records for decades. Package Components & Configuration

• 4x API 512c 500-Series Modules: A matched set of authentic API preamps featuring the legendary 2520 op-amp and custom API transformers. Unmatched for punchy rock drums, screaming electric guitars, and forward pop vocals. 
• BAE 6-Slot Lunchbox Chassis: A premium, heavy-duty 500-series rack known for having incredibly robust shielding and power rails. Leaves two open slots available for your choice of EQs or compressors to build a complete custom tracking strip. 
• External BAE Power Supply: Includes the original, heavily-regulated external BAE PSU and locking umbilical cable, isolating noisy AC transformers far away from your mic signals. 

Condition & Details

• Studio History: Meticulously minded and kept in a clean, smoke-free, climate-controlled professional control room environment. 
• Functional State: 100% operational across all 4 preamp modules and all chassis slots. The front-panel XLR/TRS combo inputs, polarity toggles, 48V phantom switches, -20dB pads, and mic/line selector buttons engage and track flawlessly. All LED level meters are fully intact and bright. 
• Cosmetic Condition: Excellent overall condition. The individual API module faceplates are crisp and clean, and the BAE chassis is clean on the face and structurally sound but does have some obvious rack scarring on the top, as pictured.
