01Overview

The OmniTec-67A is an effects plugin in the preamp category, developed by Black Rooster Audio. It is modeled on the Altec 1567A, a rack-mounted tube mixer from the early 1960s known for its gritty, dense character. The plugin is built for adding warmth and saturation to tracks that sound too clean or sterile, and it is offered in 64-bit builds for Windows and macOS.

Tube Character, Bias and Equalization

The OmniTec-67A offers three tube types, each with its own frequency response, output gain and harmonic range, so you can shape the saturation to suit a track.

A line/mic switch selects the input source, with each setting carrying its own frequency response and impedance behavior. The plugin auto-compensates at the output stage, which keeps level changes between the two settings under control.

A vintage three-band equalizer extends the original design, with frequencies chosen to give more options than the hardware had. A bias control changes how hard the tubes are driven, shifting the sound between thin and oversaturated, with two bias options to choose from.

Typical Uses and Compatibility

Black Rooster Audio positions the plugin for vocals, bass, drum tracks and harmonically complex mixes. The developer describes the 1567A as a tool that influenced many Motown recordings, and the OmniTec-67A is designed to reproduce that colored, saturated tube sound.

The plugin runs on Windows 7 or newer and macOS 10.9 or newer, including Apple Silicon M1 and M2 Macs. It supports high pixel density displays on both systems, though Windows users should check their DAW manual for HighDPI compatibility.
