Tube-Tech CL 1B Single-Channel Optical Tube Compressor – Studio Icon

The Tube-Tech CL 1B, designed by John G. Petersen and introduced in 1991, is one of the most respected and widely used optical tube compressors in professional audio. A true studio standard, the CL 1B has earned its reputation for delivering silky, musical compression with exceptional transparency and warmth.

At the heart of the CL 1B is its optical gain reduction element paired with a tube amplification stage, creating a uniquely smooth and natural compression character. It excels on vocals, bass, acoustic instruments, and mix bus duties, offering controlled dynamics without sacrificing clarity or detail—even at higher compression settings.

The intuitive front-panel layout provides precise control over:

• Ratio
• Threshold
• Attack
• Release
• Fixed and manual timing options

This flexibility allows for everything from subtle leveling to more assertive dynamic shaping, all while maintaining the dimensional, open quality that Tube-Tech is known for.
