Volume Amp122; Volred (Main-Out + Headphone) - UHL Instruments X3-1 Owner's Manual

Volume Amp122

In addition to the accurate rotary simulation the X3 also features a separate 122 amp output. It emulates the
sound and characteristics of the 12BH7 tube and the two 6550 tubes .The tube amp overdrive starts from the
center position of the volume control. Turning the volume control clockwise adds more harmonic tube
overdrive.

Volred (Main-Out + Headphone)

The intensity of the overdrive increases loudness with increasing volume level. Full overdrive can increase
the total volume level too excessively. To accommodate that many clonewheels just add an unvariable
monotonic overdrive. This entails limited overdrive dynamics and unnatural sound. Not so with the X3! The X3
features an additional post-overdrive Volred (= volume reduction) control. The Volred control allows for fully
dynamic tube overdrive at reasonable total volume levels.
Settings:
- Volred fully turned clockwise = no volume reduction.
- Volred turned counter clockwise = reduced volume level including overdrive at MAIN-OUT jack/headphone
jack (Volume Amp122 control must be turned clockwise!).
