SPL TwinTube Processors Details

Considered one of the world's finest tube effects processors, SPL TwinTube Processor provides the two single most important artifacts generated by tubes: Saturation and Harmonics. The warmth, presence and suppleness analog tube and coil filtering provide can enrich any production, regardless of the music genre.

The TwinTube

SPL TwinTube Processor Module is the first ever combination of two essential tube effects into a single processor, that is, saturation effects along with harmonics processing. Both stages work separately from each other and are based on an individual tube circuit, therefore each module employs two tubes. The effects can therefore not only be applied both individually or separately, but also in common.


Saturation effects are generated through the tube being pushed to and beyond its normal operating limits. In contrast to semiconductors, a tube thus pushed to such levels does not clip from a certain level, approaching more gradually its level limits and thereby producing its typical tonal result, which in audio signal processing can have such often profitable aural effects­""on one hand (and depending on the amount applied), from subtle to extensive harmonic distortion and on the other hand, a compaction of the sonic event, that is, a limiting effect that exhibits a pleasant, rounded or soft sound. Acoustically and also in its range of applications this can be compared very well with tape saturation effects.

Harmonic Distortion

Harmonic distortion and limiting are the generally known, "classic"¯ tube effects, which are today cornerstones of sound processing. But other less known and potentially important effects are a tube"?s ability for improving presence and spacial qualities through its processing of specific regions of the overtone series.

A special circuit comes into play for overtone/harmonic processing that involves a combined coil/condenser system working in conjunction with the tube. The control reacts dynamically to the audio signal and thereby processes both overtones as well as a signal"?s phase structure.

The processing of the phase structure influences the moments of acoustic perception and occurs in microsecond time divisions "" it has to do nothing with the cancellations one associates with 180-degree signal shifts. A decisive factor in resultant tonal quality is the alignment of level relationships the overtone spectrum. Such overtone "enrichment"¯ does not operate on the generator principle of exciters (wherein distortion is added to the original signal). In this case the TwinTube harmonics control effects a rather a more equalized overtone structure resulting in a sound which in effect appears much more in the foreground, but without doing so through extreme level changes. Thus, for example, a voice appears immediate apart from the overall mixture, "sitting"¯ clearly outlined in the mix"?s foreground.

SPL TwinTube Processors Features

  • TwinTube's saturation effects are sonically comparable to the effects of tape saturation
  • SATURATION for more warmth and loudness; subtle to clear effects
  • HARMONICS for more presence and clarity without adding appreciable levels (as with EQs); moves signals to the front of a mix
  • Extremely versatile for all kinds of signals, such as vocals, acoustic guitars, drums, strings, brass etc.
