PROGRAMMABLE EQ USER’S GUIDE SA170
overview Thank you for purchasing the Source Audio Programmable EQ. The Programmable EQ is a compact, 7-band digital equalizer with four user preset locations. It uses high-precision processing combined with professional quality analog/digital converters for superior tone. The digital nature of the unit offers a significant advantage over analog equalizers in that presets can be easily saved and recalled. The MIDI input and Backpage features further extend the capabilities of the unit.
CONNECTIONS 1. Power To power the unit, connect the included 9V battery or connect a Source Audio 9V power supply to the 9V DC jack. Note: Use of a non-Source Audio power supply may damage the unit and void the warranty. 2. Guitar/Audio Connections The unit has ¼-inch mono input and output jacks for use with guitar, bass, and other instruments. Note: The unit will not power up until a ¼-inch plug is inserted into the input.
CONTROLS EQ Display: The heart of the Programmable EQ is the 7-band graphic equalizer display. The LED display shows the currently active settings of the equalizer within a range of +/-18 decibels (dB) for each of the seven accessible bands. The left and right arrow buttons select the frequency band to be adjusted and the main encoder knob adjusts the level of the selected band up or down. The center frequency (in Hz) of each band is indicated at the bottom of the display.
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 3 times quickly when the saving process is complete.
MIDI Control The Programmable EQ features a MIDI input that can be used to remotely engage and bypass the unit as well as selecting presets. It also allows for potential future firmware updates for feature changes or future interfacing with a software editor.
Backpage Parameters The Programmable EQ features an additional set of functions called Backpage Parameters. These features can be accessed in Backpage mode only. In this mode, the equalizer display takes on some secondary functionality. To enter Backpage mode, press the left arrow band select button and the SAVE button simultaneously. The display will change to reflect the current Backpage parameter settings.
In Backpage mode, the first four columns of the display are used to edit four different parameters. Each parameter is denoted by a two letter abbreviation. They are as follows: OE – Octave Extension: This parameter allows an 8th band to be added to the equalizer, the 8th 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.
S – Auto-Scroll: This parameter enables/disables the auto-scroll funcA tion. 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 get unique 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.
