CONTROL IDENTIFICATION AND FUNCTION
1. GLOBAL BYPASS:
This switch disables all functions except the input gain control and the subwoofer level
control. When bypassed, the input circuitry still functions so that proper levels are passed
through. This is especially necessary if the unit is used to shift signal level from –10 dBV to
+4 dBu to match outboard equipment. The subwoofer crossover circuit still operates (without
the kosmos

oops, I mean a red LED. Illumination indicates bypass mode, but after living in color in OZ,
the black and white of Aunt Em's farm will appear even more drab than when you left!
2. LEVEL:
This control sets the magnitude of the earthquake (input gain and output level of the unit).
For optimum signal to noise and performance, it should be set so that the 0 dBu LED is
flickering most of the time and the +10 dBu LED does not blink. The +10 dBu LED indicates
bass content in the source material will cause possible output clipping or sanity damage. The
detented center position is the unity gain point at which the sensation of a northern California
quake can be experienced without the resultant damage.
3. CUT SUB BASS FROM MAIN:
This switch removes the QUAKE sub harmonics and the THUD bass from the main left and
right outputs. This allows all the added bass to be sent only to the subwoofer output when a
3-speaker system is used. When the left and right speakers cannot handle the additional
bass produced, this is the best way to route low frequency enhancements. The XPANSE is
always sent to the mains and is not affected by this switch's setting.
4. SUB-TERRANEAN SHIFT:
This switch changes the sub harmonic tuning between two speaker size settings. The "out"
position has a higher epicenter (center frequency) that is more suitable for small speakers.
The difference 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.
5. QUAKE:
This control adds a synthesized bass signal one octave lower than the source signal. The
adjacent yellow LED indicates tectonic activity in the sub bass range. This feature generates
bass sub harmonics that would register on a seismograph yet 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, care must be taken to prevent amplifier
clipping and speaker damage by excessive bass levels. It's louder than you think.
