Retro Instruments 176 compressor limiter S/N 1211 - MINT and Boxed!

 |  RI176sn1211

Classic compressor reproduction, one of two available, consecutive serial numbers and MINT condition, boxed.

Sorry, this item was sold out.

Based on the infamous UA 176, the genesis of compression, Retro have taken this classic design, added some features for the modern recording studio and produced something that can truly be considered ‘desert island worthy’.


  • Authentic variable-mu tube design
  • Precision Knob scales for easy recallability
  • Continuously variable attack and release time
  • Four settings of compression ratio from soft compression to limiting (2:1, 4:1, 8:1, 12:1)
  • Wide-Range Sidechain Highpass Filter
  • Vocal Asymmetry Tool
  • Hard-wire Bypass Switch
  • Interstage Transformer Bypass Switch
  • High Quality VU Meter switchable between Input, Output and Gain Reduction
  • XLR input and output connections
  • IEC power connector
  • 115/230V AC Mains
  • Integral tube balance test
  • Easy stereo strapping of two or more units
  • Selected NOS tubes and components

The unit is in MINT condition, has hardly ever been used and has never been rack mounted so no rack marks. Comes with manual and original box.

We doubt if you will find a finer example and if you need a stereo pair we have another for sale (see website) with consecutive serial number…
