Description

The Drawmer OC1 500 Series Opto Compressor brings smooth, musical dynamic control to the popular 500 series format, combining the character of optical compression with the flexibility expected from a full featured studio processor. Designed for everything from vocals and acoustic guitars to complete mixes and other instruments, it delivers a warm, natural sound while giving users precise control over how compression is applied. Its comprehensive control layout includes input and output gain, threshold, ratio, attack, release, and a wet/dry mix control for parallel compression, making it easy to fine tune performances or add subtle polish to recordings.

The OC1 also includes creative shaping tools that help refine the final sound. BIG mode helps preserve low frequency impact while reducing unwanted pumping, and AIR mode maintains clarity and detail in the high frequencies for a more open, transparent result. The CRUSH saturation circuit adds harmonic richness and classic analogue character, while Program mode provides a more natural release response during heavier compression. Stereo linking, comprehensive metering, and a true hard wire bypass complete a feature set that makes the OC1 a versatile choice for recording, mixing, and mastering applications. Designed and hand built by Drawmer in the UK, it delivers professional performance in a compact single slot format.

Features

Optical Compression
Delivers smooth, warm, and natural dynamic control. Especially well suited for vocals, acoustic instruments, and other sources that benefit from transparent compression.

Complete Compression Controls
Provides full control over threshold, ratio, attack, release, input, and output levels for precise dynamic shaping.

Parallel Compression
Includes a wet/dry mix control that makes it easy to blend compressed and uncompressed signals for greater impact while preserving natural dynamics.

Precision Recall
Detented controls allow settings to be accurately repeated, making session recall simple and consistent.

BIG Mode
Enhances low-frequency response by reducing excessive bass-triggered compression, helping mixes sound fuller and more balanced.

AIR Mode
Preserves high-frequency detail during compression, adding openness and clarity without sounding harsh.

CRUSH Harmonic Saturation
Adds analogue-style warmth, harmonic richness, and subtle character to give recordings more depth and presence.

Program-Dependent Release
Automatically adapts release behavior to the incoming audio, helping reduce pumping and maintain a more natural sound.

Stereo Linking
Allows adjacent modules to work together for consistent stereo compression across linked channels.

Output Gain Control
Lets you restore or adjust signal level after compression for proper gain staging.

Comprehensive Metering
Displays gain reduction along with input or output levels, making it easy to monitor processing.

Hard-Wire Bypass
Routes the input directly to the output when bypassed, allowing instant comparison with the unprocessed signal.

500 Series Design
Brings Drawmer’s full-featured compressor workflow into a compact single-slot 500 Series module.

Hand-Built in the UK
Designed and manufactured by Drawmer for professional studio applications.
