- Page 2 It offers some new and different distortions ranging from the more organic to synth-like and octave effects. The Soundblox 2 version of the Multiwave brings a new compact physical format and many new and useful features designed for easy on-stage use.
- Page 3 OVERVIEW DIVERSE SOUND PALETTE Featuring 23 varieties of our unique distortion algorithms with an added CLEAN BOOST mode. MULTIBAND PROCESSING Signal is split into multiple bands and distorted individually for unprec- edented sound clarity. STATE-OF-THE-ART DSP Our proprietary 56-bit Digital Signal Processor, the SA601, and crystal clear 24-bit converters.

Page 4: Quick Start
To power the unit, connect the included DC adapter power supply to the 9V DC jack on the back panel. Note: Using a non-Source Audio power supply could damage the unit. Please be very cautious when using a 3rd party supply. - Page 5 3. BRIEF KNOB, FOOTSWITCH, AND BUTTON DESCRIPTIONS (see Controls section for more details) SUSTAIN: adjusts input gain to the front-end compressor. • DRIVE: the amount of distortion gain applied to the signal. • TONE: cuts or boosts the selected TONE SHAPE (Treble, Mid, or Bass) •...

Page 6: Theory Of Operation
THEORY OF OPERATION The Soundblox 2 Multiwave Distortion provides some unique distortion sounds. In creating this effects pedal, we didn’t intend to duplicate, model, or emulate any existing types of distortion. The types of algorithms we use to create the distortion are quite different from the standard set although with certain settings the results can sound similar. - Page 7 The shapes of the distortion curves are also different from standard distortions. Normally, as the input signal voltage rises, the output voltage also rises, but begins to level off and finally pins (or clips) at a maximum value. With a foldback curve, for large enough values of the input, the out- put will begin to decrease.
- Page 8 MULTI-FUNCTION IN (optional): The multi-function input is a flexible control input for use with external controllers. It can accept digital or analog signals which allows the Soundblox 2 Multiwave to interface with the following accessories: SA110/SA115 Hot Hand Wireless Adapter •...
- Page 9 CONTROLS: KNOBS EFFECT (not labeled) The effect knob selects which distortion type will be used. There are 23 effect positions (0 through 22) around the knob as well as a setting for CLEAN BOOST. In the CLEAN BOOST mode, the distortion effect is bypassed but the output knob and tone controls still apply.
- Page 10 SUSTAIN There is a compressor before the distortion. The SUSTAIN knob adjusts the input gain of the compressor. Increasing the SUSTAIN control will result in a higher signal level going to the distortion, even when DRIVE remains fixed. Increasing the amount of compression on the signal effectively creates more sustain.
- Page 11 BOOST TONE Note: Since the Soundblox 2 Multiwave preset values can differ from the physical knob positions, it can be useful to determine the positions of the preset knob values. To do this, start with the pedal in bypass and set all of the knobs to the full counter-clockwise position.

Page 12: Controls: Buttons
Since distortion effects can have very high signal gain, the background noise and hum are also gained up and can become undesirably loud. Enabling the noise gate on the Soundblox 2 Multiwave will help silence the background noise when the guitar is not being played. There are 4 levels for the noise gate threshold: OFF (all LEDs off), LOW, MED, HIGH. - Page 13 CONTROLS: FOOTSWITCHES There are two footswitches on the Soundblox 2 Multiwave. 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.

Page 14: Effect Types
EFFECT TYPES Here are some brief descriptions of the effects included in the Soundblox 2 Multiwave. The EFFECT knob settings are split into two major catego- ries: MULTI BAND and SINGLE BAND. The MULTI BAND settings use the band splitting discussed in the Features section and the SINGLE BAND settings do not. - Page 15 MULTI BAND: FOLDBACK 4–9 The use of foldback in these settings creates more extreme distortion sounds. The higher numbered effects have more foldback creating even more distortion. Power chords will work well. MULTI BAND: OCTAVE 10–14 Settings 10 and 11 give the purest octave effect. Settings 12 through 14 also have foldback and can get pretty strange.

Page 16: External Control
EXTERNAL CONTROL One of the new Core Features of the Soundblox 2 line of effects pedals is the addition of the Multi-Function Input. The Multi-Function input is an intelligent control input that can accept both digital and analog control signals. The Multi-Function input replaces the Sensor Input on previous Soundblox pedals. - Page 17 Press the NOISE GATE button again while holding the TONE SHAPE button to resume normal Noise Gate adjustments CONTROL ASSIGN Both the expression pedal and hot hand inputs are by default mapped to control the morph parameter. This effectively allows the control of any parameter since the morph is between two distinct preset effect settings.
- Page 18 MORPHING The Multi-Function control input can be used to morph between the two presets. For example, let’s say preset 1 is saved as a Multiband normal setting and preset 2 is a Multiband octave setting. By connecting an SA161 Expression Pedal, you can fade from the preset 1 Multiband normal sound into the octave effect saved in Preset 2 by rocking the expression pedal from heel to toe.

Page 19: Midi Control
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. - Page 20 Hot Hand unit and use them to control either the Morph or whichever parameter has been assigned. The Soundblox 2 Multiwave can also be calibrated to change the midpoint of the Hot Hand control range. To do this, follow the calibration procedure below.

Page 21: Universal Bypass
By default, the Soundblox 2 Multiwave is set to use the relay-based true bypass. To switch to buffered bypass press and hold the right footswitch when powering up the pedal. Continue to hold the footswitch until the footswitch LED blink slowly 3 times. -
