processing if 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 drums. Since it boosts the low frequency
portion significantly, care must be taken to prevent amplifier clipping and speaker damage by
excessive bass levels, especially if small speakers are used.

e:: The activity of the QUAKE circuitry is indicated by this light. It is provided as a reference;
sub-harmonics are still being generated when it is not lit if useable bass information is present,
although the level may be very low. If there is no bass in the source, this lamp will not light.

miiccss:: There are instances when you want the sub-harmonics to tightly track the natural bass, and
other times you may want it to follow loosely. The QUAKE DYNAMICS control allows this to be
adjusted. The tight setting adds punch, the loose setting adds a fuller low end, just as a damped bass
drum is percussive and an undamped one has increased sustain.

d:: This control adds a specific band of bass frequencies (natural, not synthesized) to the sub-
harmonics generated by the QUAKE process. It is tuned roughly an octave above the sub-harmonics,
and is used to even out the low end balance. The THUD and Quake waveforms are phase synchronized,
so adjustments effectively modify the wave-shape as well as the amplitude, and may sound different
than expected.

e:: This control works in conjunction with the BAROMETRICS control. It simultaneously adds high
frequency components and increases stereo width. The minimum position is the flat setting, as it is
advanced, the left-right image becomes wider and clarity is increased. It has been designed to pull
vocals more to the front of the mix and to reduce speaker comb filtering effects. It will not create a
stereo image from a mono source, but will improve one that is already there.

counterclockwise (DENSE) the phase manipulating processes dominates. When set clockwise
(THIN), it accentuates the high frequency enhancements. The typical setting will be close to the
center of the range.

err:: Built into the kosmos Pro is a 90 Hz sub-woofer cross-over. The sub-woofer signal is the
sum of the QUAKE output, the THUD output, and the low frequencies from the 90 Hz cross-over
network. This control sets the output level. When the bypass switch is engaged, the added QUAKE and
THUD components are removed, leaving only the low frequency cross-over material. In this mode, the
control behaves as a normal sub-woofer level control.

even in bypass mode, since the unit has built-in active level shifting capabilities with its independent
