The Chimera is a single channel 500 series compatible Opto compressor, and can be used for mono applications, or can be paired with a second Chimera for stereo applications. The Chimera™ contains a transformer input & output, as well as all discrete circuitry and a Class AB transistor output circuit. At the heart of the Chimera™ is the T4B optical cell, which utilizes an Electroluminescent (EL) panel and photo resistor cells to achieve gain reduction.
