Drawmer S73 Intelligent Master Processor is a modeled three-band mastering compressor with intelligent presets and mid/side controls, offering two versions for standard and Amp Room workflows.

Purpose and Design
The Drawmer S73 Intelligent Master Processor brings the circuit of the Drawmer 1973 three-band FET compressor into a software tool designed to simplify mastering. It combines a three-band compressor, mid/side processing, and transparent filters in a semi-automatic unit. The goal is to provide the decisions a mastering engineer would make without requiring deep technical tweaking.
Modeled at the component level, the S73 aims to capture the analog character of the original hardware. It includes a dedicated version for Amp Room, letting guitar and bass producers apply the same mastering-style processing to their tracks. This dual version expands its use beyond a traditional stereo bus.
Key Capabilities
The S73 offers a Style parameter with ten preset mastering techniques, organized into three categories: Clean, Bass Control, and Spatial. This allows users to switch between different processing approaches quickly, finding a suitable starting point for a mix. An Amount knob increases processing along designed gradients, and an Air switch adds a high-frequency boost for added shine.
A dry/wet mix knob enables parallel compression, letting you blend the processed signal with the original. Output gain control facilitates volume-neutral A/B comparisons, so you can judge the effect without level bias. Left and right VU meters monitor output levels per channel, giving visual feedback on the stereo signal.
Workflow
The S73 is designed for a set-and-forget workflow. Place it on your mastering bus or a track, select a Style that matches your desired outcome, and adjust the Amount to dial in the intensity. The Air switch can add polish, and the dry/wet knob is available if you want a parallel compression effect.
For Amp Room, the S73 integrates into the guitar and bass platform, allowing you to combine it with amps, cabs, and pedals. You can insert it on a track or bus and use the same Style and Amount controls to shape the tone, making it suitable for both full mixes and individual instrument processing.
Practical Applications
Use the S73 to make mixes brighter, louder, or wider with minimal effort. The presets are designed to apply expert mastering techniques, so you can achieve a polished sound without guessing at compression settings. This is useful for home producers, mix engineers finalizing tracks, or anyone wanting quick improvements on a mix bus.
In Amp Room, the S73 can help craft record-ready guitar tones by adding clarity and definition. Apply it to a guitar bus to control dynamics or spatial width before the recording stage. The volume-neutral comparison feature helps you assess whether the processing is truly beneficial, making it a practical tool for both music production and sound design.
