Vari Tube Recording Channel

The variable character of the Vari Tube Recording Channel’s preamp lets you shape the tone of your recording from clean and direct to vintage and fat. Using the passive equalizer built on the Pultec principle, you can add silky highs, enhance the low-mid body of a vocal, or gently filter out problematic frequencies. The unique combination of Vari-μ and opto compression in one unit is a globally unmatched feature and expands your sonic palette with fantastically musical compression tone.

Opto Compressor

An LED shines on a light-sensitive resistor, controlling the gain based on input level. The memory effect of the resistor supports the automatic timing control of the compressor. The result is an open, airy, and smooth compression that keeps levels consistent without noticeably affecting microdynamics.

Vari-Tube Compressor

This stage directly alters the gain of a control tube. The regulation is more immediate than in the opto compressor. The result is a sound that cuts through even the densest mixes with striking presence — yet retains its warmth.

The routing between compressor and EQ is switchable. The EQ can also be routed into the compressor’s sidechain, enabling frequency-dependent compression and de-essing.
If you have a recording that hasn’t yet been processed through the VTRC, the new line input allows for post-processing. The signal bypasses the mic input transformer and uses a separate transformer designed for line-level signals. This gives you access to the full feature set — from preamp to EQ to compressor — for high-level sources as well. For stereo applications, two (or more) VTRCs can be linked via the link connector.

New Features

Vari-μ compressor (usable in series with opto compressor)
Line input with dedicated transformer
Linkable for stereo operation
EQ: Additional high band at 24 kHz for optimal air boost
Switchable compressor timing
Improved input stage
Numerous refinements and upgrades

Proven Features

Opto compressor (usable alongside Vari-Tube compressor)
Passive EQ for musical tone shaping
Mic preamp ranging from clean to fat-sounding
Switchable order of EQ and compressor
EQ can be routed into compressor sidechain

The VTRC is a pro-level device and therefore includes no presets.
To help you get started with testing and learning, Tegeler provides a few suggested settings as a good starting point.

Default Setup: Set all knobs to 0, all switches down, Mic/Line and +48V as needed

Vocals: Gain at 10, input level so the meter needle just moves, lowcut at 80 Hz for male, 160 Hz for female vocals. EQ on, frequency at 16 kHz with boost at 6. Opto and Vari-Tube compressors on. Adjust gain reduction to stay below 6 dB on peaks.

Fingerpicked Guitar: Gain at 1, input level so the needle just moves, lowcut at 80 Hz if other bass is present. EQ on, cut 300 Hz by 3 dB if needed, boost 6 kHz by 6 dB. Opto compressor on, limit gain reduction to 4 dB on peaks. For more punch, increase gain and adjust input.

Strummed Guitar: Gain at 10, input level so the needle just moves, lowcut at 80 Hz if bass is present. EQ on, cut 300 Hz by 3 dB if needed, boost 12 kHz by 6 dB. Vari-Tube compressor on, adjust gain reduction to stay below 6 dB.

Bass: Gain at 10, input level so the needle doesn’t exceed 0. Cut 300 Hz by 3 dB, boost 2 kHz by 3 dB. Opto compressor on, set gain reduction between 3–6 dB.

Saxophone: Gain at 10, input level so the needle just moves, lowcut at 80 Hz, EQ on, frequency at 16 kHz with a 6 dB boost. Vari-Tube compressor on, gain reduction between 3–6 dB.
