Know before you buy
The 3124V adds two key features: variable output level control and a selectable 3:1 output transformer tap. These additions allow you to drive the preamp harder for more saturation while maintaining control over your final output level.
Yes, the front-panel hi-Z instrument inputs are designed specifically for direct recording of guitars, basses, and synthesizers. They bypass the microphone input stage to provide the correct impedance matching for these instruments.
The 3:1 tap allows you to push the input stage for more harmonic saturation and vintage-style warmth without overloading your converters. It essentially gives you a 'thicker' sound by altering how the output transformer reacts to the signal.
Yes, the 3124V provides plenty of clean gain to handle most ribbon microphones effectively. Its discrete circuitry is designed to maintain a low noise floor even when you need to push the gain for quieter sources.
Yes, each of the four channels features individual 48V phantom power switching, allowing you to use condenser microphones alongside dynamic or ribbon mics simultaneously.
The 3124V is built to handle both environments. Its robust rackmount design and reliable discrete circuitry make it a standard choice for professional live rigs, broadcast setups, and high-end recording studios alike.
