Two Channel Tube Microphone Preamp for Studio and Live Recording
This two-channel tube microphone preamp delivers up to 70 dB of gain and is designed for studio recording, broadcast production, and live sound applications that demand warmth, clarity, and flexibility. It operates in stereo or dual-mono mode, making it suitable for tracking vocals, acoustic instruments, drum overheads, or full stereo sources. With its dual-tube gain stage and rackmount 2U design, it provides professional-level control and tonal shaping for engineers who want both character and precision.
70 dB of Gain with Dual Tube Gain Stage
Featuring a tube-based amplification stage, this mic preamp offers selectable plate voltage settings for different tonal responses. Users can choose between high and normal plate voltages to shape harmonic content and dynamic response. This flexibility allows you to tailor the sound for clean, detailed recordings or richer tube coloration, depending on the source. The result is a versatile microphone preamplifier that works equally well for vocals, guitars, bass, and studio microphones of all types.
Variable Input Impedance for Microphone Matching
Each channel provides adjustable input impedance, allowing you to optimize performance with a wide range of dynamic, condenser, and ribbon microphones. Proper impedance matching can significantly influence tone, sensitivity, and transient response. This feature gives engineers additional control over how microphones interact with the preamp, making it a powerful tool for shaping sound at the source.
Front Panel Instrument Inputs and DI Capability
Two front-panel instrument inputs allow the unit to function as a dual-channel direct box for guitars, bass, and keyboards. Automatic input selection simplifies workflow when switching between microphone and instrument sources. This makes it ideal for project studios, mobile recording rigs, and live environments where flexibility and quick setup are essential.
Mid Side Recording Support and Stereo Operation
The preamp supports mid/side microphone techniques, enabling advanced stereo recording configurations. It can be set to stereo-linked or dual-channel operation, giving you control over how the output section behaves. This makes it suitable for recording drum overheads, acoustic ensembles, or ambient room microphones while maintaining proper stereo imaging and phase integrity.
Comprehensive Channel Controls and Monitoring
Each channel includes a variable low-cut filter to reduce unwanted low-frequency rumble, switchable +48V phantom power for condenser microphones, and a phase reverse switch for alignment adjustments. Output level can be set for either +4 dBu or -10 dBV systems, ensuring compatibility with professional and consumer gear. Large, dual backlit VU meters provide clear output level monitoring, while multi-colored LED arrays indicate tube gain levels for precise visual feedback.
Rugged 2U Rackmount Design for Long Term Use
Housed in a durable steel 2U rack chassis, this tube microphone preamp is built for reliability in studio racks and touring setups. Its sturdy construction and intuitive front-panel layout make it a dependable choice for engineers who need consistent performance across sessions. Whether used in a commercial recording studio or a live production environment, it delivers dependable tube preamp performance with professional connectivity.
