effects are selected the DELAY knob adjusts the delay time
between the dry and modulating signals. Because of the
similarity between flangers and choruses, a flanger can easily
be adjusted to resemble a chorus and vice-versa. As a rule of
thumb, short delay times create flange effects while long delays
produce chorus effects. Set the DELAY knob between 7 and
11 o’clock for flange effects and between 3 and 5 o’clock for
chorus.
When phaser effects are selected, this knob adjusts the
frequency center point of the phase modulation. Turn the
FREQUENCY knob clock-wise to modulate the phaser over
higher frequencies and give the effect a brighter sound.
•FEEDBACK (Red LED):The FEEDBACK knob controls the amount
of wet signal fed back into the effect. Much like the harmonic
feedback created between a guitar pick-up and an amplifier,
increasing the FEEDBACK on the Orbital Modulator creates
a more resonant and ringing response, giving the effect more
prominence.

level, ranging from zero gain to +6dB. Unity gain is found at
roughly 12 o’clock.
•LoRETAIN (Red LED):The LoRETAIN function adjusts the
frequency below which the original signal remains unaffected.
This function is especially useful for bass players—increasing the
LoRETAIN insures a solid low-end foundation while maintaining
the characteristics of the chosen effect. Guitarists may also find
it useful—if the FEEDBACK control is cranked up, increasing
LoRETAIN will prevent excessive volume fluctuations in the
lower frequencies.
•TREMOLO (Green LED): The TREMOLO knob adjusts amplitude
modulation. Unlike traditional tremolo, the Orbital Modulator’s
amplitude modulation is embedded within the flanger, phaser,
and chorus effects, creating a wide range of very unique and
three-dimensional modulation effects. But the TREMOLO function, if dialed in correctly, will also create sounds reminiscent
of classic amplifier generated tremolo or replicate the sound
of a rotating speaker (see the EFFECT TYPES section for more
detail).
10 | Controls: Knobs
Page 12
• MIX (Red LED): The MIX knob controls the ratio between the wet
and dry signals. This knob is split into two regions: normal and
inverted wet signals. The 12 o’clock position produces a 100%
dry signal—as the knob is turned clockwise from 12 o’clock the
wet signal gradually increases as the dry signal decreases until
reaching a 100% wet mix at its right-most position. The process
is repeated with an inverted wet signal in the counter-clockwise
direction. The inverted wet signal interchanges the positions of
the peaks and valleys in the frequency response and tends to
reduce bottom end. The marks at approximately 10 and 2 o’clock
around the MIX knob indicate the point of a 50/50 wet/dry mix.
Set the MIX knob to a 50/50 ratio for the most prominent phase
or flange effects.
Factory Defaults: Given the number of different functions available on
the OPTION KNOB, it can be useful to “zero” all of the controls to a
default value. We pre-loaded the Orbital Modulator with unique default
settings that are a good starting point for each effect type (note: the
CLASSIC effect type defaults to a flanger setting). You can recall these
values at any time by pressing and holding the OPTION SELECT button
until its three LEDs blink two times.
Note: To learn the knob positions of the default settings, go to the
SB2 Orbital Modulator product page on our website and download the
PDF titled, SB2 Orbital Modulator Preset Suggestions.

MOD SOURCE Knob (A)
When Hot Hand, MIDI, or an expression pedal are not being used, the
Orbital Modulator features three different types of modulation control:
Envelope Follower, Sine Wave LFO, and Square Wave LFO. The MOD
SOURCE knob controls a gradual blend between them, so setting this
knob between two of the modulation graphics will create a sound with
elements of both modulation forms.
• Sine Wave LFO ( ): The sine wave LFO produces a very
smooth independently moving modulation. Use the sine wave
LFO for traditional flanger, chorus, and phaser effects.
• Square Wave LFO ( ): Unlike the smooth modulation of a
sine wave, the square wave LFO has a blockish sound similar
to a sequencer. We recommend using a square wave LFO for
dramatic, choppy sounding tremolo effects.
• Envelope Followers ( / ): An envelope follower responds
to the amplitude (or volume) of the incoming signal and creates
a control signal, which modulates the wet signal in the same
manner as an auto-wah. The MOD SOURCE knob can set the
modulation direction either forward ( ) or backward ( ).
SPEED Knob (B)
Depending on the modulation source, the SPEED knob controls either
the rate of the LFO, the attack and decay times of the envelope follower,
or the smoothing of Hot Hand.
When using LFO modulation, turning the SPEED knob clock-wise will
increase the modulation rate.
When using an envelope follower, turning the SPEED knob clock-wise
increases the envelope attack, which determines how quickly the envelope rises after the input level increases—the decay rate is the amount
12 | Controls: Knobs
Page 14
of time it takes for the envelope to drop back when the input signal
decreases. The decay is fixed to a rate twice as slow as the attack.
While Hot Hand is engaged, the SPEED knob controls the amount of
smoothing. Turning the SPEED knob clock-wise increases the smoothing
and makes Hot Hand less responsive and less jittery sounding.

Discovering Preset Knob Positions
Since the Orbital Modulator preset values can differ from the physical
knob positions, it may be useful to determine the positions of the preset
knob values. To start the process, put the pedal in bypass and set all
knobs to the full counter-clockwise position. Next, enable the preset
and slowly turn each knob up one at a time until the preset indicator
LED begins to blink rapidly. The rapid blinking indicates that the current
position of the knob matches the saved value.
Controls: Knobs | 13
Page 15
CONTROLS: FOOTSWITCHES
There are two footswitches on the Orbital Modulator. The left footswitch
corresponds to preset 1 and the right footswitch corresponds to preset
2. Pressing either of the footswitches will engage the respective preset.
Pressing the same footswitch again will put the effect back into bypass
mode. Pressing the other footswitch will engage the other preset without
going into bypass. The illumination of the LEDs labeled “1” and “2”
indicate which preset is currently enabled. While the effect is in bypass
mode both LEDs remain off.
When a preset is enabled and any sort of adjustment is made, the
indicator LED for that preset will begin to blink, showing that the preset
has been edited. After a preset has been edited, save it by pressing and
holding either footswitch. The corresponding LED will blink quickly to
indicate that the preset has been saved. Once changes are saved, the LED
will illuminate continuously. An edited preset can be saved to either of
the two preset locations. For example if preset 1 has been selected and
edited, it can be saved to preset location 2 by pressing and holding the
right footswitch.
Note: Changes made to a preset will be lost if you go into bypass or
switch to another preset without saving.
14 | Controls: Footswitches
Page 16
TAP TEMPO MODE
The Orbital Modulator’s LFO rate can also be adjusted on-the-fly via TAP
TEMPO. To enter TAP TEMPO mode put the pedal into bypass, then press
and hold the footswitch (and corresponding preset) to which you would
like TAP TEMPO applied. When the preset LED opposite the pressed footswitch begins to blink, the pedal is in TAP TEMPO mode. The footswitch
below the blinking LED now controls the LFO rate. Tap the footswitch at
least two times in rhythm to set a new LFO speed. The LFO rate is reflected in the blinking LED—the time between each blink represents one
cycle of the LFO. Follow the same procedure to disengage TAP TEMPO.

Here are some brief descriptions of the EFFECT SELECTOR knob settings
on the Soundblox 2 Orbital Modulator.
FLANGER & CHORUS
CLASSIC: Flanger and chorus effects are very similar—both combine
the original dry signal with additional modulating clone signals. For this
reason, we’ve positioned the CLASSIC effect type, which uses a single
modulating signal, in both the FLANGER and CHORUS effect categories.
As a rule, short delay times between the dry and modulated signals
create the traditional jet-engine “whoosh” associated with flangers while
longer delay times create lush chorus effects. When using CLASSIC, set
the DELAY knob between 7 and 11 o’clock for a flange effect and between
3 and 5 o’clock for chorus.

THRU ZERO: The THRU ZERO effect type is our version of “through zero
flange” (a.k.a. tape flange). In the world of pre-recorded music this
dramatic effect is achieved when the modulating signal actually passes
through and moves ahead of the original signal—obviously, this is a
difficult feat to pull-off during a live performance (without the assistance
of a time machine). The OM achieves this effect with two delay lines.
The first is a very short, but stationary delay line, which functions as the
dry signal—the other signal modulates. As the modulating signal passes
through and moves ahead of the stationary tap we hear the classic
through zero twist (a split second of complete phase cancellation) as the
frequency response inverts.

similar to that found in a rotating Leslie speaker.
VIBE: The VIBE effect type was modeled after the Shin-Ei Univibe, the
original rotating speaker simulator (i.e. the original phaser pedal). This
effect contains 2 relatively wide frequency notches spaced farther from
one another than a typical phaser.
VARIABLE STAGE PHASERS: As a rule, every pair of phase shift stages
creates one notch in the frequency response, so the 4, 6, 8, and 12 STAGE
PHASERS produce 2, 3, 4, and 6 frequency notches, respectfully. As you
progress from the 4 to the 12 STAGE PHASERS, the effect will sound
more complex and pronounced.

TREMOLO
Though TREMOLO is not one of the effects listed around the EFFECT
SELECTOR knob, turning up the Orbital Modulator’s TREMOLO knob can
produce several traditional or non-traditional tremolo effects. For a basic
tremolo, set the MOD SOURCE to a standard sine wave, dial the EFFECT
SELECTOR to CLASSIC, turn the DEPTH and DELAY all the way down
and the MIX to 100% wet, then set the TREMOLO somewhere between 9
and 11 o’clock. For some more unique tremolo effects, try dialing in more
DEPTH and experiment with the different effect types.

One of the Core Features of the Soundblox 2 line of effects is the MULTIFUNCTION Input. The MULTI-FUNCTION input is an intelligent control
input that accepts both digital and analog control signals. It replaces the
SENSOR input on previous Soundblox pedals. The MULTI-FUNCTION

MIDI CONTROL
The Orbital Modulator can be controlled via generic MIDI messages. To
access MIDI functionality, the unit requires a Source Audio Soundblox 2
MIDI Adapter. Please check www.sourceaudio.net for availability. The
adapter connects to the Multi-Function input and provides standard MIDI
IN and OUT 5-pin DIN connectors.
Using Soundblox 2 pedals with MIDI greatly extends the functionality of
the units. Having MIDI I/O allows for remote automation, external controllers, firmware updates and more. If you have more than one Soundblox 2
pedal, only one MIDI Adapter is necessary. The Multi-Function output
will act as a MIDI thru to pass the MIDI messages on the other pedals via
a Source Audio SA160 Daisy Chain cable.
For information on using your Soundblox 2 with MIDI and for MIDI
mappings, please visit our website at www.sourceaudio.net.

USE WITH HOT HAND
All Soundblox pedals are compatible with our Hot Hand accessories. Hot
Hand units consist of a ring-mounted accelerometer that detects motion
and controls effect parameters. To enable Hot Hand functionality, connect
the Hot Hand receiver or base station to the MULTI-FUNCTION IN and
select HH mode with the CONTROL INPUT button. The pedal will now
accept input signals from Hot Hand and use them to control standard
modulation or the assigned parameter.
The Orbital Modulator can also be calibrated to change the midpoint of
the Hot Hand control range. To do this, follow the calibration procedure
below. Note that calibration is only used for Hot Hand mode and
calibration is NOT required before use.
To perform a calibration:
1. Select a preset by pressing a footswitch.
2. Enable Hot Hand control by selecting HH mode with the CONTROL
INPUT button.
3. Press and hold the CONTROL INPUT button until the HH red LED
begins to blink slowly (note: this is the same as the control assign
procedure).
4. Put the Hot Hand sensor into the desired calibration position.
5. Press the footswitch for the currently selected preset.
6. The HH LED will blink when the calibration is complete.
If you have trouble with calibration and need to get back to the default
setting, place the sensor on a flat, level surface with the blue LED facing
down and run the calibration procedure again.

Page 26
UNIVERSAL BYPASS
Most effect pedals offer either true or buffered bypass. Soundblox 2
offers Universal Bypass, which allows you to select between the two.
We recommend that you choose between the Orbital Modulator’s active
analog (a.k.a. buffered bypass) and relay-based true bypass (a.k.a.
true bypass) based on what is needed in your pedalboard’s signal chain
(Ideally, the first pedal in a signal chain should be a buffered input
followed by true bypass in the rest of the signal chain).
By default, the Soundblox 2 Orbital Modulator is set to use the relaybased true bypass. To switch the pedal to buffered bypass press and hold
the right footswitch when powering up the pedal. Continue to hold the
footswitch until the corresponding LED blinks 3 times. The pedal is now
in buffered bypass. To switch back to true bypass, replicate this process
with the left footswitch.
Both bypass methods have pros and cons associated with them. Buffered
bypass provides a consistent input impedance so that if the input is
susceptible (like a guitar pickup) to variations in input impedance there
won’t be a noticeable change in tone. True bypass has the benefit of
providing a dedicated hardwire bypass signal path; however, it can cause
clicks/pops and typically requires a mechanically complex 3P3T (3-pole,
3-throw) switch. Soundblox 2’s special relay-based true bypass eliminates
the need for the 3P3T switch and thus the popping/clicking problem.
