A 2 slot 500-series preamp/compressor combo!
Giving you both a 2264E-style compressor and 1073-style mic preamp in a 2-slot 500 series unit, the 2264JR 500 Series Compressor and Microphone Preamplifier from Heritage Audio has a fully discrete Class A signal path, and is transformer balanced. The compressor is based on key components and the schematics from the company's 2264E rackmount compressor, while the 1073-style preamp provides up to 60 dB of gain. All rotary controls on the unit are stepped for precise recall. It provides discrete inputs for mic and line level signals. Please note, the compressor and mic preamp modes cannot be used simultaneously.
