Tegeler All Analog, 40 Channel, Tube Summing Mixer

The Tegeler Audio Tube Summing Mixer is a professional analog summing solution designed to bring the classic sound of console summing into modern hybrid studios. Its tube and transformer-based signal path opens mixes with warmth, harmonic richness, and cohesive depth that digital summing alone can't replicate. With up to 40 summing channels across balanced inputs and a stepped output level control for consistent recall, it lets engineers blend multiple tracks into a unified analog stereo bus with expressive character and presence. Ideal for mix-bus summing and immersive analog workflows, this summing mixer delivers musical integration, dimension, and analog tone to digital productions.
