EQ2 Programmable EQ User Guide

Welcome

Thank you for purchasing the Source Audio EQ2 Programmable EQ! The EQ2 is the pedal for the
working musician; the tone-chaser. With 10 fully customizable bands of graphic or parametric
equalization, adjustable Q controls, full stereo capabilities, and complex routing options, this EQ
pedal will fit in virtually any setup. A modern update to its predecessor, the SA170 Programmable
EQ—which landed onto the boards of pros such as David Gilmour and John Mayer among many
others—the EQ2 boasts One Series hardware, full MIDI compatibility, and a real-time editing
interface for a DAW-like experience.
The EQ2 is our first pedal to support two-way mobile Neuro communication via the USB Mini port. It
also includes a Control Input port, and 5-pin MIDI DIN In and Out/Through ports for full MIDI
integration. The pedal features true stereo operation, including a Split Mode which allows you to
create a separate EQ curve for each output.
Coupled with the EQ2 is its own sound editor in the Neuro App and Desktop Editor, making custom
equalization easy and intuitive to create and share with other users. EQ2's sound editor features
deep editing controls such as complex routing, channel volumes, and an optional noise gate and
limiter. Visit the Quick Start guide for basic operation or move on to the following sections for more
in-depth information about the EQ2. Enjoy!

    To power the unit, connect the included 9V DC negative-tipped 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. A power supply with insufficient current levels may also cause noise or other unpredictable behavior.

  • Page 5: Connections

    Connections Guitar/Audio Connections Using standard ¼” mono (TS) cables, connect your guitar, bass, or other instrument to the I NPUT jack and your amp (or the next audio device in the signal chain) to the O 1 jack. If you have a UTPUT second amp, connect it to O UTPUT...
  • Page 6 The ring contact on O 2 acts as a data UTPUT connection for the Neuro App, passing data from the EQ2 to the next Source Audio effect in your signal chain. You can daisy-chain the Neuro App data regardless of whether O 2 is UTPUT configured to output audio or not.
  • Page 7 The 3.5 mm C port connects to external control devices such as the Source Audio Tap ONTROL NPUT Tempo Switch, Source Audio Dual Expression Pedal, Neuro Hub, and Hot Hand Motion Controller. For more information, refer to the Expression Pedal Input Neuro Hub sections of the User’s Guide.

  • Page 8: Basic Operation

    Basic Operation The EQ2 defaults to each band in the flat position, Q value of 1.0, and set to the standard grapgic-EQ frequency values (the value written on the face of the pedal under each band) of 31, 62, 125, 250, 500, 1k, 2k, 4k, 8k, and 16k Hertz.

  • Page 9: The Options Menu

    Adjusting the Q Factor (Width) of a Band Let’s say you’re used to your DAW equalizer software, and you’re used to being able to make a particular EQ band more wide or narrow. This can be done on the EQ2! To do this, select a band, then press + hold the E .
  • Page 10 GAIN Sets the gain per channel. Each channel has its own gain control from -18dB to +18dB. Useful for matching the Channel 1 and Channel 2 levels when Split mode is used, similar to a line selector pedal. Note that these channel gain values are separate from the master output volume control. SPLIT By default, all of the controls for Channel 2 will match the Channel 1 settings.

    Controls Rotary Encoder Knob This is the key to the whole operation. Push + rotate the Encoder Knob to select a frequency band. Turn the Encoder Knob clockwise or counterclockwise to boost or cut the selected band. Double tap the Encoder Knob to “start over” and set the bands back to flat. Push + hold the Encoder Knob to enter the Options screen.
  • Page 12 Control Input Button This small button located at the top of the pedal is used to enable or disable external control. It also is used in many of the Hardware Shortcuts. See the External Control section and the Hardware Shortcuts section for more details.

  • Page 13: Common Eq Configurations

    Common EQ Configurations With 10 customizable bands and +/- 18 dB of boost or cut on tap for each band, there are thousands of configurations possible when equalizing an instrument. The sheer amount of options can be paralyzing for anyone new to EQ or unsure of where to start. Below are a few common EQ curves that can serve as jumping-off points or simply help you dial in some interesting tones.
  • Page 14 Drastic Mid Scoop You might have heard the term “mid-scooped” to describe modern metal guitar tones. Since the guitar is already a midrange instrument, cutting those frequencies while boosting the high and low frequencies can give it a big, thick tone. Take in small doses; not enough mid frequencies can make a guitar get “lost”...

  • Page 15: Stereo Operation & Signal Routing

    Single Coil Sanctuary Barely cutting each frequency while giving a spike to about 5-7kHz can make a humbucker-equipped guitar sound similar to a single coil Strat or Tele. This setting works notably well for darker or warmer-toned guitars, like a Les Paul, and can really liven up a clean tone. Stereo Operation &...
  • Page 16 Mono In, Mono Out This is the most common use case. Plugging the incoming signal into INPUT 1 with OUTPUT 1 connected to an amp (or the next device in the signal chain) produces a standard mono signal. Dual processing effects are also mixed down a single output. Mono In, Stereo Out This is a very common use case that allows you to create some nice stereo imaging from a single mono instrument input or use your EQ2 as a splitter to send your signal to two separate outputs.
  • Page 17 Stereo In, Stereo Out This mode should be your default selection for Stereo In, Stereo Out applications. Stereo In, Stereo Out allows you to continue your stereo chain of effects. Stereo In, Mono Out This mode will accept stereo input on jacks INPUT 1 and 2. Inputs 1 and 2 are sent to Channel 1 and 2 equalizers, respectively.

    External Loop 2 -> Loop 1 This routing mode supports a use case that involves placing two different EQs at two different points in your signal path. In this routing mode, a loop for external effects is placed after Channel 2, before Channel 1.
