E EN NG GL LI IS SH H ™ ™ C CE EL L- -2 2A A Dual Compressor/Expander/Limiter Thank you for purchasing the CEL-2A. You’ll find plenty of features and versatility in this single-rack space‚ dual compressor. The CEL-2A can be operated as either two independent compressors or as a linked‚ stereo compressor with true RMS summing. High-quality‚ voltage-controlled amplifier (VCA) and RMS-rectifier integrated circuits are used to maintain low distortion and excellent noise performance. This unit has fu

C CE EL L- -2 2A A A Ap pp pl li ic ca at ti io on n G Gu ui id de e The key to successfully using a compressor is to visualize the signal’s envelope and then create a scheme that closely tracks that flow. Thus, a kick drum, with its sharp attack and fast decay, requires a tracing envelope with a quick attack, somewhat heavy clamping, and fast release of the compressed signal. The CEL-2A has enough parameter control to “dial-in” almost any desired configuration. With the unique architecture of

A Ac co ou us st ti ic c G Gu ui it ta ar r If the guitar is mic’d, it will usually have a darker tone than a signal derived through a built-in pickup. To address the tone of a mic’d acoustic, the key is to allow enough of the initial percussive phase of the tone to pass intact. At the same time, enough control must be exercised to prevent the tail of the signal from overlapping the next strum. If the ambient noise is low, leave the expansion gate out of the path. However, if the background is
