Tegeler Audio Manufaktur Tube Summing Mixer – high-end analog summing mixer blending vintage console warmth with digital workflow convenience. Ideal for professional studios seeking total recall and analog glue without sacrificing modern efficiency. Features 2x20 channels (40 total) for complex mixes, with cascading capability for surround or expanded setups. Stepped output attenuators ensure precise, repeatable mixes.
Each channel employs discrete Class-A transistor buffers and ECC81/82 tubes for rich harmonics and saturation. Switchable input modes (0dB/-12dB) prevent clipping, while transformer-balanced outputs deliver low-distortion signal. No EQ or dynamics per channel—focuses on pure summing with optional tube saturation. Compatible with DAW stems for hybrid analog-digital production.
Handcrafted in Germany with premium components, its robust chassis suits fixed installations. Enhances stereo imaging and depth, elevating ITB mixes to console quality.
