## Description

Tubebox — a single-slot 500-series tube microphone preamp that boasts pristine audio output, superior-quality high-end design, and a value price. The small but mighty device features a Class A tube preamplifier, switchable phantom power, phase invert, selectable -20dB pad, and a super fast in-line optical compressor. The front panel includes a TRS microphone input—a standout feature typically not found on 500-series preamps. The easy-access interchangeable 12AX7 preamp tube allows you to experiment with a variety modern and vintage tubes to customize the Tubebox’s sound and performance to your taste. The switchable (in/out) compressor provides adjustable attack and release, and when it’s in use, the on-board VU meter automatically changes from displaying master level to amount of gain reduction, so you can view the exact results of the compression being applied. Editing is done using our smooth, responsive (and eye-catching!) hand-machined controls. And last but not least: The Tubebox audio circuit uses LME49720 ultra-low distortion/low noise Op Amps, for suberb audio output.

## Features

- Suitable for use in all 500-series-compatible systems
- 12AX7 electron tube
- Class A transformless high voltage signal path
