The Pendulum OCL-2 is a two channel electro-optical compressor/limiter designed for the utmost in transparency, detail and versatility. The incredibly short signal path design uses a proprietary optocell input attenuation network in front of an all tube class A gain stage. Since the signal path is entirely transformerless, we've eliminated the coloration inherent in traditional transformer-coupled tube designs. The result is an open, detailed sound without the sluggishness and over compression associated with older tube circuit design. The resulting clarity and super -fast attack time that you can dial in can only be achieved with modern tube circuit design. 
The OCL-2 is modeled after the characteristics of a vintage LA-2A but with much faster attack and releases in response to transients while still maintaining the warmth of the tube.

The OCL-2's soft-knee design offers smooth, effortless dynamic control with the ratio adjustable from light compression to limiting. Our unique sidechain circuit linearizes the optical gain element to reduce distortion, and achieves much faster attack and release times than encountered with conventional optical compressors. And stereo linking is accomplished with the flip of a switch .

In the FAST mode, the optical cell operates with very fast attack and release times, which are peak-averaged by the rapid operation of the cell. This mode is remarkably free of pumping artifacts even at high compression levels. It's the ideal choice for 'invisible' dynamics processing, either for tracking or tight program compression.

The PRESET mode consists of six classic attack/release time settings that are optimized for program compression, including two settings with program-dependent release times.

The MANUAL mode offers total control over the attack and release times, which is particularly useful for creative compression effects or for processing bass guitar.

Most important, the hard bypass switches on the front panel conveniently allow a quick determination of exactly what the OCL-2 is, or in most cases, isn't doing to your signal.
