One of the core features of the Soundblox 2 line of effects is the MULTI-
FUNCTION Input (A). The MULTI-FUNCTION input is an intelligent control 
input that accepts both digital and analog control signals. It replaces the 
SENSOR input on previous Soundblox pedals. The MULTI-FUNCTION input 
connects to wired or wireless Hot Hand accessories, the Source Audio 
Expression Pedal, or the Source Audio Soundblox HUB. The Soundblox HUB 
provides full MIDI I/O, a standard passive expression pedal input, a dedicated 
Hot Hand input, and USB connectivity. The HUB can connect up to 5 
Soundblox 2 pedals together to share control inputs or to save multi-pedal 
presets via the Scene Saving functionality.

• MIX (Green LED):  Adjusts how much of the dry signal (no effect), wet 
signal (full effect), or wet signal with “LoRETAIN”, are blended together. 
The 12 o’clock position produces a 100% dry signal. As the knob is turned 
clockwise from 12 o’clock, the wet signal gradually increases as the dry 
signal decreases, until reaching a 100% wet signal at the knob’s 
maximum position (fully clock-wise). As the knob is turned counter-
clockwise from the 12 o’clock position, the dry signal decreases as the 
wet signal with “LoRETAIN” gradually increases, until reaching a 100% 
wet signal with “LoRETAIN” at the knob’s minimum position (fully 
counter-clockwise). “LoRETAIN” assures a solid low-end foundation, 
“LoRETAIN” adds in a considerable amount of the lowest frequencies in
the dry signal, so the initial thump and bottom end is preserved even
after the filter effects are applied.
• VOLUME (Red LED): Adjusts the output level of the pedal, ranging from 
zero output to +6dB. Unity gain (equal volume to the bypass signal) is 
found roughly at 12 o'clock. Changing RESONANCE or DRIVE may affect 
the output volume.
