Pair of Eckmiller W86a passive equalizer modules, mounted in a 1U rack. Known for their smooth and musical characteristics, these equalizers are often used in mastering studios to finish and sweeten up source material. Each module has large and chunky transformers that provide extra warmth and body to anything you put through them. The -15 position on the right module doesn't seem to be responding. Perhaps it needs a cleaning? Otherwise these have tested in good working order.
