The

is the next generation of the award winning kosmos sub-harmonic enhancement system. Through special
processes (patents pending), it can provide planet rattling bass while simultaneously adding clarity, definition, and sparkle. Its
design puts it at home in any rack of professional gear, where it will soon become the most used piece.

The design philosophy of this unit was to create a processor that would enable a small set of speakers to appear as if they
were larger, and large speakers to sound huge, while at the same time improving the fidelity and image. By adding generated
bass sub-harmonics and high frequency harmonics that are not present in the original source, these enhancements do not
cloud the mix, but add separation.

To keep the sub-bass from walking over other instruments in the mix, it must be precisely created with a defined envelope in a
specific frequency range. We call this circuitry QUAKE. It operates by continuously monitoring the input signal for bass content
that meets defined criteria, then generates synchronized low frequency material an octave below it. It has a unique feature that
is found on no other bass processors- an adjustable dynamics control which modifies the bass tracking parameters from tight
to loose. The tight setting provides higher definition and punch, the loose setting allows a longer settling time. The output
frequency range of the process can be shifted higher or lower to match the speaker size by using the SUB-TERRANEAN shift
switch. The sub-harmonic activity is monitored and indicated by a light and the output level is fully adjustable.

In addition to the QUAKE process, there is an additional bass circuit, THUD, tuned roughly an octave above the sub-harmonic
range, which can be used to fill in and fatten out the upper‚ low end. A tuning switch removes some of the higher bass
frequencies, giving it a deeper tonality. Since the QUAKE and THUD circuits are phase synced, the two adjustments interact,
supplying waveform and level adjustment for the bass enhancement process.

High frequency content and stereo imaging can be improved with the three atmospheric controls (XPANSE, BAROMETRICS,
and STRATOS), which give increased separation and clarity. The XPANSE works with the BAROMETRICS control to provide
phase and frequency manipulation that works especially well with vocals. The STRATOS control adds a high frequency
harmonic sheen.

All inputs and outputs are balanced. To allow for maximum flexibility, input and output level controls are provided with
selectable metering. The sub-woofer output has built in cross-over circuitry and a separate level control to supply an equalized
bass signal for systems with subs. The QUAKE and THUD processes can be removed from the main left and right outputs,
leaving them only in the sub-woofer output.

S/PDIF in and out is also provided for direct connection to other digital audio equipment. If used as an analog to digital
converter, the kosmos Pro defaults to a 44.1K Hz sampling rate, if receiving input from another source, it locks onto the
incoming clock. The status is indicated on the rear panel.

All together, the systems in the kosmos Pro affect the soundscape from underground to upper atmosphere. It will rattle your
planet, or just your windows.

1.

GGlloobbaall BByyppaassss::

This switch disables all functions except the sub woofer control which still functions as
a cross-over level control (with the kosmos bass effects turned off) when bypassed. The status is
indicated by a red LED which is lit when bypassed.

2.

IInnppuutt LLeevveell::

This control sets the input gain of the unit. For optimum signal to noise and performance,
it should be set so that the 0 dB LED (+4 dBu) of the level meter (when set to monitor the input) is
flickering most of the time and the clip LED does not blink. The center detent position is the unity gain
point. If the levels are too high, heavy bass material could result in clipping and distortion.

3.

MMeetteerr SSeelleecctt::

The meter will display the level of either the input signal after the input level control or
the output. The top LED has two colors; it will illuminate yellow as a warning, then change to red 4 dB
below the clip point.

4.

OOuuttppuutt LLeevveell::

The output of the unit is set by the output level control. The detent position is the unity
gain point, with an additional 10 dB gain available. Set this control so that the output level does not
change when the bypass switch is pressed. This control also affects the S/PDIF output level.

5.

CCuutt SSuubb--bbaassss ffrroomm MMaaiinn::

This switch removes the QUAKE sub-harmonics and the THUD bass from the
main left and right outputs. (It does NOT remove normal bass from the program material.) This allows
all the ADDED bass to be sent only to the sub woofer output when a three speaker system is used.
When the left and right speakers can not handle the additional bass produced, this is the best way to
route low frequency enhancements. The XPANSE, and STRATOS signals are always sent to the mains
and are not affected by this switch’s setting.

6.

SSuubb--tteerrrraanneeaann SShhiifftt::

This switch changes the sub-harmonic tuning between two speaker size settings.
The “out” position has a higher center frequency which is more suitable for small speakers, the “in”
position shifts the frequency content lower for larger speakers that can handle the deeper bass. If there
is no noticeable difference, the speakers may not be able to reproduce the deep bass, so the small
speaker setting is recommended. This trims back the lowest frequencies, keeping the amplifier from
delivering power that the speaker can’t use or may even be harmful.

7.

QQuuaakkee::

This control adds a synthesized bass signal one octave lower than what is present in the
source. It works in tandem with the DYNAMICS control. The circuitry of this process looks for specific
bass information (frequency and amplitude) and generates natural sounding sub-harmonics. It does no

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.

8.

QQuuaakkee AAccttiivvee::

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.

9.

DDyynnaammiiccss::

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.

10.

TThhuudd::

This control 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 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.

11.

DDeeeeppeerr::

This narrows the THUD circuitry’s range by removing some of the higher bass frequencies. This

gives another option for low frequency adjustments.

12.

XXppaannssee::

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.

13.

BBaarroommeettrriiccss::

This control pans between the two processes of the XPANSE circuitry. When set
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.

14.

SSttrraattooss::

This control adds high frequency harmonics to the source. The frequency range is higher than

the XPANSE range and compliments it. It will add crispness to dull source material.

15.

SSuubb--wwooooffeerr::

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.

16.

PPoowweerr::

Applies AC mains power to the unit and causes the power LED will light. Line power is required
even in bypass mode, since the unit has built-in active level shifting capabilities with its independent
input and output level controls.

Used to connect the supplied AC mains cord. Make sure that the correct line voltage is

applied, or damage to the unit could result. (See markings on unit.)

18.

SS//PPDDIIFF::

These are the stereo digital inputs and outputs provided to connect to other digital equipment,
such as a computer or DAT deck. The input syncs to an incoming clock (up to 48 kHz) if one is present,
defaulting to 44.1 kHz if one is not. Two lights indicate if it has locked onto an input clock or if there is
an error in the data. The digital input is only connected to the analog processes if the kosmos Pro input
selector switch is in the S/PDIF mode, but it will always be used (if it has a clock) as a sync to set the
internal sampling frequency. The S/PDIF output is always live and is the same as the main left and right
outputs. Digital full-scale (zero) corresponds approximately to the analog clipping point (+22 dBu). At
typical operation levels this leaves 18 dB of headroom.

19.

SSuubb--wwooooffeerr OOuuttppuutt::

This is a 1/4" TRS electronically-balanced output, that can be used either in
balanced mode (with a 1/4" TRS jack) or unbalanced (standard 1/4" jack). This output supplies the
signal for the sub-woofer amplifier (line level).

20.

LLeefftt//MMoonnoo aanndd RRiigghhtt OOuuttppuuttss::

The left/mono and right outputs are electronically balanced, with pin 2
(and tip) positive. The XLR and 1/4" TRS phone jacks are directly wired in parallel. Balanced and
unbalanced jacks should not be mixed on the same channel outputs since this would cause both to
become unbalanced. The left/mono output has the mono output signal when in the mono mode.

21.

IInnppuuttss::

The left and right input jacks are balanced with pin 2 (and tip) positive. The XLR and 1/4" TRS
jacks are directly wired in parallel. If a mono signal is used, apply it to the left/mono jack (XLR or 1/4")
and depress the MONO switch.

22.

IInnppuutt SSeelleecctt::

Either the analog (XLR and 1/4”) inputs or the S/PDIF digital input can be selected.
Selecting one disconnects the other. This affects both the left and right inputs. The mono switch is
disabled when the unit is set for S/PDIF inputs.

23.

MMoonnoo::

If only one input of the kosmos Pro is used, this switch should be pressed. It insures proper
internal levels to the processes which rely on having both left and right signals. This switch does not
affect the S/PDIF units.
