The all-analog Drawmer 1973’s features include three independent compressor sections with two variable-frequency 6dB/octave crossovers to separate them into low, middle, and high frequency compression sections. Each section contains familiar threshold, gain, attack, and release controls, along with gain-reduction metering. Moreover, each section can be independently muted or bypassed for straightforward setup and monitoring. The low section possesses a "Big" switch for enhanced low-end, whereas the high section possesses an "Air" switch for enhanced high-end. The three sections are recombined to form the "wet" signal, which can be mixed to variable degree with the dry signal for easy parallel compression. Illuminated VU meters are designed to make monitoring compression and output intuitive.
