Lunar Phaser User’s Guide Welcome Thank you for purchasing the Lunar Phaser. This powerful stereo effects pedal features a collection of meticulously crafted phaser sounds ranging from 60s vibe sounds to quad-stage 80s shredder solos and modern sounds that explore new experimental sonic territory.
The USB and Neuro ports transform the Lunar from a simple phaser pedal into a powerful multieffects unit. Using the free Neuro App (iOS and Android), a wide range of additional control parameters and effect types (chorus, flanger, resonator) are accessible. When used together with the Neuro Hub, the Lunar is fully MIDI-controllable and 128 multi-pedal presets, or “scenes,” can be saved for instant recall on the stage or in the studio.
Quick Start Power To power the unit, connect the included 9V DC power supply to the jack labeled DC 9V on the back panel. Warning: Using a non-Source Audio supply, especially an unregulated supply, could damage the unit. Please be very cautious when using 3rd-party power supplies. Guitar/Audio Connections Using standard ¼” mono cables, connect your guitar, bass, or other instrument to the INPUT 1 jack and your amp (or the next audio device in the signal chain) to the OUTPUT 1 jack.
Effect Switch: Selects between the three basic phaser effect types – Vibe, Classic, and Multi. Footswitch: Enables or bypasses the phaser effect. The large LED will be lit green when the phaser effect is engaged.

Connections Input Side Connections Input 1 This is the primary input for guitar, bass, or other instruments. It can also accept line-level inputs. Connect it to your instrument or other audio source using a mono (TS) ¼” cable. Input 2 Input 2 can act either as an audio input or as the data connection for the Neuro App, or both at the same time. Input 2 as an Audio Input The tip contact on Input 2 acts as a secondary input for guitar, bass, or other instruments.
Output Side Connections Output 1 This is the primary output. Connect it to your amplifier, recording interface, or the next device in your effects signal chain using a mono (TS) ¼” cable. Output 2 Output 2 can act either as an audio output or as the daisy-chain data connection for the Neuro App, or both. Output 2 as an Audio Output The tip contact on Output 2 acts as the secondary audio output. It carries an audio signal when the Lunar is configured with a signal routing that uses stereo outputs.
Example Neuro Daisy-Chain Connections Mono Audio Path with Neuro Daisy-Chain In the case of a purely mono audio signal path, the Neuro data can be input to the first effect directly from the mobile device and then carried on to the second effect via TRS cable.
Power and Control Connections DC 9V (Power) Connect to the included 9 Volt DC power supply. The power supply must be regulated at 9 Volts (direct current), able to source at least 180 mA (milliamps) of current, and the plug should have a tipnegative, sleeve-positive polarity (the center tip is ground and the sleeve is power). USB Connect to your computer (Mac or Windows) to the Lunar’s USB port (denoted by the icon) using a standard mini USB cable.
Basic Phaser Operation A phaser, or phase shifter, is an effect that was originally designed to reproduce the sound of a “Leslie” rotating speaker cabinet. The phaser effect can be produced by several methods, the most common of which involves a network of all-pass filters, which introduce phase shifts into the input signal. When the phase-shifted signal is mixed with the original input, audible interferences are created, creating notches.
PHASE SHIFT The depth of the LFO can also be changed to make the phaser effect more or less prominent, as shown in this graph: TIME Finally, the shape of the LFO can be changed to give the phaser effect a different character.
Effect Types The Lunar includes three basic effect types, with more effects available in the Neuro mobile app. Vibe The Vibe Phaser effect 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.
Controls Control Input Button Control LED Depth Knob Speed Knob Effect Switch Resonance Knob Shape Knob Engage/Bypass LED Engage/Bypass Footswitch Knobs Depth Knob SA241 PHASE SHIFT PHASE SHIFT Controls the depth of the LFO, which determines how prominent the phaser effect is. When the depth is set fully counter-clockwise, the phaser effect will be most subtle. When the depth is set fully clockwise, the phaser effect will be most prominent.
Speed Knob PHASE SHIFT PHASE SHIFT Controls the frequency of the LFO, which determines how fast the phaser effect is. The minimum setting is 1 Hz (one LFO cycle per second) and the maximum setting is 10 Hz (ten LFO cycles per second). TIME TIME Low Speed High Speed Resonance Knob Sets the resonance of the notch filters in the phaser effect. Subjectively, a higher resonance will result in a more metallic, bell-like or chime-like sound, whereas a lower resonance will sound more subdued.
Effect Switch Selects between the three basic phaser effect types – Vibe, Classic, or Multi. These effects are described in further detail in the Effect Types section. LEDs Engage / Bypass LED The Engage / Bypass LED above the footswitch indicates if the phaser effect is active (lit green) or bypassed (not lit). When the user preset mode is enabled, the LED will turn red. See the Preset Storage and Recall section for more information about user presets.
Change any parameter you wish (effect switch, depth, speed, shape, and level knobs). Once you have made a change, the engage/bypass LED will begin to blink. When you are ready to save, press and hold the footswitch for a few seconds. The LED will blink three times to show that the preset was saved. Exiting Preset Mode When Preset Mode is active, bypass the effect using the engage/bypass footswitch. The engage/bypass LED should be dark at this time.
Out. If cables are connected to INPUT 1, INPUT 2, OUTPUT 1, and OUTPUT 2, then the routing mode will be set to stereo in, stereo out. Other routing options are available via MIDI or the Neuro App. A few different routing options are displayed below. The right side of each diagram shows inputs 1 and 2, the left side shows outputs 1 and 2, and phaser effects A and B are in the center.
A simple example of these four bands in action is shown in the graph below. In this example, Band 1 is a low shelf filter at 100 Hz with a 6 dB cut, Band 2 is a peaking filter at 620 Hz with a 3 dB cut and relatively high Q, Band 3 is a peaking filter at 3 kHz with a 1.5 dB boost and relatively low Q, and Band 4 is a high shelf filter at 10 kHz with a 2.5 dB cut.

Low Cut Filter The Lunar also includes a low cut filter (a.k.a. high pass filter) with an adjustable frequency. This filter is very useful for cutting out low frequencies that do not contribute to the sound of the instrument, as well as subsonic frequencies which cannot be heard at all. Bass players often use low cut filters set very low (around 10 Hz to 30 Hz) to reduce speaker excursion and improve the clarity of the bass.
In the case of an expression pedal with a TRRS plug, like Source Audio’s expression pedals, the tip connection is power, the first ring is the X axis expression signal, the second ring is the Y axis expression signal, and the sleeve connection is ground.
3. Move the expression pedal over the range of motion you would like to use to control the Lunar. If you would like to use the expression pedal’s full range of motion, then make sure to move the pedal all the way from its minimum position to its maximum position. Note that you can create “dead zones,” if desired, by only moving the expression pedal over a limited region of its full range of motion. 4. After setting the expression pedal range, click the Lunar’s footswitch once.
4. 5. 6. 7. you perform. The Lunar will intelligently select the X or Y axis of the Hot Hand automatically, based on the motion of the ring. After setting Hot Hand range of motion, click the Lunar’s footswitch once. The calibration is now complete, and the Control LED will blink faster (about 2 blinks per second). Now, it is time to map the Hot Hand to the effect parameters. Move the knob(s) you wish to control with the Hot Hand to their minimum desired position, then click the Lunar’s footswitch.
Main Menu The main menu includes links to the three main sections of the app: Sound Editor allows the user to edit the current effect or create a new sound from scratch. These sounds can be burned into the internal preset memory (three sounds corresponding to the three positions of the effect selector switch, and an additional preset accessible via the footswitch), saved to a preset file in the app, emailed to friends, posted to the Neuro Community site, and more.
Sound Editor The Sound Editor displays a wide range of parameters that can be changed to create different sounds. The Sound Editor works kind of like a remote control for a TV – only the parameters you touch on the screen will be modified on the hardware; all other parameters remain unchanged. The links at the bottom of the screen allow access to the File Menu, the Burn command, and the Send All command.
File Menu The File Menu displays different options for the sound you’re currently editing in the Sound Editor. Save Saves the current settings from the Sound Editor. If you haven’t saved yet, this will perform a Save As. Save As Allows you to save the current settings to a new file. You can choose a file name and description. Share Allows you to send the current settings to a friend as a text message or email attachment.
Burn The Burn command takes the current sound that is running in the hardware and “burns” it to the internal memory for later use. Burn works as a “what you hear is what you get” type of control; it will save all of the settings in their current state, as you hear them, and put those into memory. This will not necessarily match the exact settings shown in the Sound Editor for all parameters unless you have performed a Send All command first.
Browse Sounds The Browse Sounds screen displays lists of presets that can be easily loaded into the hardware. Just tap on a preset name to send it to the hardware, and you should be able to hear it instantly. Presets are divided into four sections: User: Presets that you have created and saved. Factory: Presets that were created by Source Audio. New presets will automatically be added to this list as Source Audio creates them.
Hardware Options This screen shows some advanced options. Effect Bypass Mode Selects which bypass path will be used for presets that use hardware bypass mode. True Bypass (Relay) uses two relays for true bypass switching. Active Analog (Buffered) bypass uses a buffer to help prevent signal loss and clicking. MIDI Channel (Device ID) Selects which channel (1 to 16) the hardware will respond to on Hub and USB-MIDI inputs.
Quick Preset Mode Allows preset mode to be enabled/disabled in 0.8 seconds instead of 5 seconds (by holding down the footswitch). Neuro Hub (Formerly the Soundblox Hub) The Source Audio Neuro Hub (sold separately), unites Source Audio pedals from the Soundblox 2 and One Series families to create a single, stage-ready system. It features shared MIDI, passive expression pedal input, Hot Hand connectivity, and USB, and can connect to up to five Source Audio pedals.
For the enable/disable footswitch, continuous control values in the range from 0 to 63 will bypass the Lunar and values in the range from 64 to 127 will enable the Lunar. For the effect type switch, continuous control values map directly to each effect type. 7 = Vibe, 8 = Classic (4-Stage), and 10 = Multi (8-Stage). Other values map to additional effect types that are available in the Neuro App. Any MIDI CC, from 0 to 127, can be mapped to a control on the Lunar.
After the Lunar receives its first MIDI clock message, the function of the Speed Knob changes. Instead of controlling the speed of the LFO directly, it controls the number of subdivisions are in the LFO, using the MIDI clock as a basis for the tempo. One, two, three, or four subdivisions can be created. Musically speaking, this means that the LFO can run at the rate of quarter notes, eighth notes, triplets, or sixteenth notes.
External Tap Tempo The Lunar supports an external tap tempo switch that can be connected to its Control Input port. Tap tempo can be used to directly input a tempo and override the speed knob. Tap tempo is disabled by default; it can be enabled in the hardware options menu in the Neuro App. When External Tap Tempo mode is active, the Speed knob acts to set the beat subdivisions, just as it does when MIDI Clock is enabled. Source Audio makes tap tempo switches that are compatible with the Lunar.

Not connected properly: Check Hot Hand connections. Unit Appears Dead / No LEDs Lit Wrong power supply: Use correct power supply. See the DC 9V (Power) section for more details. Corroded power cable plug: Check power plug for corrosion on sleeve. Swap out power supply if necessary.
Why doesn’t the Lunar respond to MIDI messages being sent to it? By default, the Lunar should respond to MIDI continuous controller messages on channel 1 (in technical terms, this means that the lower 4 bits in the command byte of MIDI messages should be 0000 in binary or 0 in hexadecimal). The Lunar’s MIDI channel can be configured using the Neuro App.
How do I enable extended effect types via MIDI? Refer to the MIDI Learn section to map a MIDI continuous controller to the Effect Type switch. Then, send a CC message with one of the following values to enable a certain effect type: CC Value 0 1 2 3 4 5 6 7 8 9 10 11 Effect Type Classic Flange/Chorus Shadow Thru-Zero Resonator 1 Resonator 2 Dual Chorus Quad Chorus Vibe 4 Stage Phaser 6 Stage Phaser 8 Stage Phaser 12 Stage Phaser Additional effect types may become available in future updates.
