SOURCE AUDIO SA170 overview

  • 1Description

Designed to be a streamlined tone controller on your pedalboard, the Source Audio Programmable EQ is a Toolblox Series utility pedal intended for electric guitar and bass, though it’s also compatible with any instrument that has a 1/4" output jack. This is an EQ pedal with seven adjustable bands, four user-editable presets, a sturdy aluminum enclosure, and a whole host of secondary functions that can be accessed from the pedal itself.

With 56-bit DSP and industry-standard 24-bit AD/DA converters, the unit provides a ±18 dB range. You can dial in the perfect tonal profile for any given song or section, and then save that profile as a preset. Then, when you want to cycle to another preset, you can do so straight from the footswitch. If you’d like to use a MIDI controller to switch presets, you can do so through the pedal’s MIDI input. Secondary features (which Source Audio deems “Backpage parameters”) let you switch the footswitch into auto-scrolling mode. Now, when you press down on the footswitch, the pedal can cycle through all four onboard presets at a rate of your choosing. You can get creative with this, as you now have a frequency-based step sequencer or tremolo at your beck and call.

This is just one example of the pedal’s secondary features. Here’s another: In addition to its EQ capabilities, the pedal can be used to achieve volume boosts of up to 12 dB, doing so in a transparent way, or in a manner that pushes your amp into a pleasant, harmonically distorted breaking-up point. This stompbox, which can operate with the included 9V battery or with compatible power supplies, also boasts a switchable bypass. True or buffered? The decision is yours.

Key Features at a Glance
±18 dB of range over seven bands. An eighth band at 62 Hz can be edited using the Octave Extend Backpage function.

A compact, rugged, cast aluminum housing.

56-bit DSP processing and industry-standard 24-bit converters.

Presets can be quickly saved and restored. All presets can be accessed via the footswitch.

Selectable bypass modes. Use either relay-based true bypass or buffered analog bypass.

Recall presets, control parameters, and engage/bypass remotely via MIDI.

Controls at a Glance
EQ Display: The heart of the Programmable EQ is the seven-band graphic equalizer display. This LED display shows the currently active settings of the equalizer within a range of ±18 dB for each of the seven accessible bands. The left- and right-arrow buttons select the frequency band to be adjusted, while the main encoder knob adjusts the level of the selected band, either up or down. The center frequency of each band is indicated in Hz at the bottom of the display.

BAND SELECT Buttons: The band select buttons flank the display and are indicated by left and right arrows. Press a corresponding button to select a higher or lower frequency to be edited.

ENCODER Knob: The main knob on the unit is an encoder-style control that allows incremental up or down level changes to the selected frequency band in 1 dB steps. The maximum range is +18 dB and the minimum is -18 dB for each frequency band.

SELECT Button: Pressing the select button will scroll through your four user presets. The display will update to show the saved equalizer curve and output for each preset location. Also, the four LEDs above the SELECT button will indicate which of the four presets is currently selected.

SAVE Button: Once a preset has been selected, it can be edited. When any of the controls are changed from their saved value, the preset LEDs will begin to blink to indicating that the preset has been edited. To save the new settings, press and hold the SAVE button for two seconds. The preset LED will blink three times quickly when the saving process is complete.

OUTPUT: This small knob adjusts the final output volume after the equalizer, it can be used to compensate the overall volume for any loss or gain in the equalizer. The OUTPUT knob setting will be saved along with the equalizer curve per preset. The OUTPUT knob is also illuminated by a blue LED which will increase in brightness as the knob is turned up. This way, the brightness of the OUTPUT knob will give some indication of the output volume setting when scrolling through presets.

ON/OFF Footswitch: Pressing and releasing the footswitch engages or bypasses the unit. When engaged, the audio input will be routed through equalizer and the output volume knob. When bypassed, the audio is routed through a hardwired relay connection directly to the output. This is sometimes referred to as “hardwire” or “true bypass.” There are no buffers or components between the input and output in bypass. The footswitch can also duplicate the function of the SELECT button. Pressing and holding the footswitch will make the unit begin to scroll through the four presets in the same manner as pressing the SELECT button. Releasing the footswitch will stop the scrolling on the last selected preset.

Additional Parameters Available in "Backpage" Mode
OE (Octave Extension): This parameter allows an eighth band to be added to the equalizer. The eighth band is at a frequency of 62 Hz, one octave below the normal low of 125 Hz. This frequency is especially helpful for use with bass. The lowest position on the display indicates this features is off. The next LED position up from the bottom indicates the octave extension is enabled. After exiting Backpage mode, the 62 Hz band can be accessed by pressing the left band select button until the 125 Hz column is selected. Pressing the left button again will shift the display and allow the 62 Hz band to be displayed and edited by the encoder. Press the right band select button to resume the normal seven-band view.

SW (Switching Speed): This parameter controls the scrolling speed when using the footswitch to scroll through presets, or when using the auto-scroll mode (see below for an auto-scroll mode overview). The full range of the display is used for this parameter. Slowest speed is at the bottom, while fastest at the top.

AS (Auto-Scroll): This parameter enables/disables the auto-scroll function. When in auto-scroll mode, the footswitch preset scroll will continue to scroll automatically even after the footswitch is released. This can be a fun way to achieve esoteric tremolo or sequencer sounds, as the unit steps through the four equalizer presets at a given programmable rate. The rate of the scrolling is controlled by the switching-speed (SW) parameter. Auto-scrolling will stop when the footswitch is pressed again. Like the OE function, this parameter uses the two bottom LEDs on the display to indicate ON or OFF.

MC (MIDI Channel): Use this parameter to edit the MIDI channel for the Programmable EQ. The display will numerically indicate the currently selected channel from 1 to 16.
