Controls

Global Bypass

Disables all the functions that the Kosmos device provides, but still passes the signal through the device.

Cut SubBass from Main

Removes the quake subharmonics and the thud bass from the left and right outputs.

Note: Xpanse is always sent to the left and right outputs (except when globally bypassed) and is not affected by this setting.

Subterranean Shift

Changes the subharmonic tuning between two speaker size settings.

When switched off, the device produces a higher epicenter (center frequency) that is more suitable for small speakers.

Tip: The difference this setting makes is subtle. Listen for its action on bass guitar frequencies. Deeper bass sounds like it is coming from the floor instead of at your chest.

Act

Shows activity from the quake circuit.

Quake

Adds a synthesized bass signal one octave lower than the source signal. This feature generates bass subharmonics that are pleasing to the ear, and does no processing when the input signal is outside of its defined range. It will thicken and deepen the bass of most program material and is especially effective on bass (kick) drums, since it boosts the low frequency portion significantly.

Caution: Care must be taken to prevent amplifier clipping and speaker damage by excessive bass levels.

Thud

Adds a specific band of bass frequencies (natural, not synthesized) to the subharmonics generated by the quake process. It is tuned roughly an octave above the subharmonics and is used to even out the low-end balance.

XPanse

This is a combination control, simultaneously adjusting high-frequency boost and stereo width. The minimum position is the flat setting. As the control is rotated clockwise, the left/right image becomes wider and clarity is increased. This feature is designed to pull vocals more to the front of the mix, while giving them a 3-dimensional quality.
