Tegeler Audio Vari Tube Recording Channel - All-in-One Tube Channel Strip
The Tegeler Audio Vari Tube Recording Channel is a premium all-in-one analogue channel strip that combines a high-quality tube microphone preamplifier, passive Pultec-style EQ, and warm Vari-Mu tube compressor in a single 2U rack unit. Hand-built in Germany with premium components including NOS tubes, custom transformers, and stepped controls, it delivers the classic tube warmth, musical compression, and silky EQ shaping that define vintage console sound — perfect for tracking vocals, instruments, and full mixes with professional polish and character.
High-End Tube Microphone Preamp
The Vari Tube preamp features a discrete Class-A circuit with a high-quality input transformer and NOS tube stage, providing up to 70 dB of clean, warm gain. Switchable mic/line and high-Z instrument inputs, +48V phantom power, phase reverse, and a variable high-pass filter offer maximum flexibility. The preamp imparts rich harmonics and depth while maintaining transparency, making it ideal for any microphone or instrument.
Pultec-Style Passive EQ
The passive EQ section emulates the legendary Pultec program equalizer with simultaneous low-frequency boost and cut (for signature “Pultec punch”) and high-frequency boost with broad, musical shelves. Stepped frequency and gain controls ensure precise, repeatable settings, while the passive design preserves phase linearity and adds vintage air and weight to vocals, guitars, and mix buses.
Vari-Mu Tube Compressor
The compressor uses a variable-mu tube circuit (6BA6 tubes) for smooth, musical dynamics with harmonic richness. Six attack/release times, progressive ratio/threshold, and the classic “All Buttons In” mode provide everything from transparent levelling to aggressive character. The compressor adds glue, density, and analog color without harshness, making it perfect for buss duties or individual sources.
