The Drawmer OC1 is a single-slot, 500 Series optical compressor module featuring comprehensive controls for precise dynamics processing. With input and output gain, threshold, ratio, attack, release, and mix controls for parallel processing, along with a plethora of signature Drawmer functions, you have complete control over how your dynamics are shaped.
Both input and output makeup gain can be adjusted between -15 and +15 dB. Threshold controls are offered between +20 and -40 dB. You can adjust the ratio between 1:1 and 10:1, and adjust attack and release between fast and slow timings. Extra button-activated functions include Big/Air—high-cut and low-cut filters, Program—a program-dependent release circuit, Link—link a second OC1 and utilize stereo dynamics processing, and Crush—add progressive harmonic saturation and auto-compression, derived from the 1971 and MQ-2. Furthermore, you can switch between input and gain-reduction metering via the eight-segment dual LED meter (I/P VU) and bypass the module (B/P).
