 ADD HISTORIC GERMAN TUBE PREAMP GAIN TO YOUR ARSENAL

The WT-72 brings you the rich, mid-forward coloration that the original V72 console modules are known for!

Inspired by the V72 modules originally built for the German Radio Network, the WT-72 offers 56 dB of gain, which can be driven by a microphone or line level source. The vintage modules only offered 34 dB of gain, so an additional 22 dB of gain is made in the WT-72 with small adjustments to the circuit while maintaining the most sought after tone and character we have all come to love.

The performance of a high-quality mu-metal shielded input and heavy duty output transformer as well as the EF86 output plate choke helps provide the character of its vintage inspiration!

The all new WT-72 sets gain with attenuation and altering AC & DC voltage feedback. DC feedback switching would normally introduce large pops, causing harm to your monitors, or even worse, your hearing. The user would need to manually lower monitor volume before switching gain, making for a frustrating experience.

A special muting system in the WT-72 performs a brief mute of the output between each step of gain. This mute eliminates the loud transient and allows the tubes to stabilise before the output becomes un-muted.

WHY IS ANY OF THIS IMPORTANT? By changing gain with voltage feedback (gain knob at 36-56 dB), there is less noise at less gain!

For example, at 36 dB of gain, you will have 20 dB less noise than at 56 dB of gain. We are limited with the amount of voltage feedback to change gain because there is a "sweet spot" for stability and frequency response. Therefore, using attenuation before the tube gain stages (gain knob at Off - 36 dB), allows the WT-72 to have the most gain flexibility and best noise performance possible.

  • TRANSFORMERS - Transformer balanced input and output give the WT-72 the character of the original
  • TUBE CIRCUITRY - Audio passes through two EF86 tubes giving 56 dB of gain
  • OUTPUT HEADROOM - A plate choke feeding the output EF86 provides large output swings at low distortion.
  • LINE INPUT - When "Line" is selected from the XLR IN switch, a 36 dB pad is placed before the input TX.
