1960

Dual Vacuum Tube Compressor & Pre-Amplifier

The Drawmer 1960 is a dual-channel valve microphone preamplifier and soft-knee compressor designed to combine classic tube warmth with modern reliability and control. By integrating multiple valve stages with low-noise solid-state circuitry, it delivers rich harmonic character alongside the precision required for contemporary recording and live sound applications.

Each channel features a high-quality mic preamp, natural-sounding tube compression, and flexible routing options, with additional front-panel DI inputs for instruments. With comprehensive control over dynamics, side-chain access for frequency-conscious processing, and the ability to operate in mono or stereo, the 1960 is a versatile front-end for vocals, instruments, and full mixes where musicality and depth are paramount.

Vintage Tone, Modern Control
Engineers and producers have long valued the unmistakable warmth and depth of vacuum tubes. By combining eight active valve stages with the low noise, stability, and reliability of solid-state circuitry, the Drawmer 1960 creates a seamless bridge between classic analogue character and modern recording precision.

Each channel features a natural-sounding soft-knee tube compressor alongside a low-noise microphone preamplifier with switchable 48 V phantom power. A front-panel auxiliary instrument preamp with EQ provides direct access for guitars and keyboards. Together, they deliver the unmistakable musicality of valve circuitry with up to 60 dB of clean, balanced gain — ideal for detailed vocal recording, instrument tracking, and direct-to-digital capture of live performances.

The Compressor
The 1960’s soft-knee tube compressor is designed for musical, transparent control with minimal setup. Threshold is continuously variable from infinity down to –24 dB, allowing signals below the threshold to remain untouched while progressively increasing gain reduction is applied above it.

Attack and release are switch-selectable, echoing the behaviour of classic all-valve compressors. Attack offers slow, medium, and fast settings, while Release provides six options, including two programme-dependent modes that adapt naturally to vocals, stereo mixes, and complex material. The release selection also subtly influences attack behaviour, expanding the unit’s tonal range beyond first impressions.

Gain Make-Up & Side Chain Control
A dedicated make-up gain stage provides up to +20 dB of post-compression boost, with switchable VU metering for either output level or gain reduction. Channels may be operated independently or linked for stereo compression.

Side-chain access points allow external EQ insertion for tasks such as de-essing or frequency-dependent compression. As with all Drawmer dynamics processors, the Bypass switch offers three modes — Normal, Bypass, and Side Chain Listen — enabling direct monitoring of external processing effects.

Professional Mic Preamp & DI
In addition to balanced microphone and line inputs, the front-panel DI input allows direct connection of instruments. With onboard EQ and ample gain to drive the valve stages into musical saturation, the 1960 functions as a DI box, equalizer, and compressor in one.

This versatility makes it ideal for adding sustain, warmth, and harmonic richness to guitars, basses, or synthesisers, while routing cleanly and confidently to a console, interface, or recorder.
