Source Audio Dual Expression Pedal User manual

  • Hello! I've reviewed the user guide for the Source Audio SA161 Dual Expression Pedal. This device features two independent expression outputs and a sensor output, which can be used with Soundblox pedals. It also has a range adjust control for one of the expression outputs. I'm ready to answer your questions about its functions and usage.
  • Can the Expression Output and Sensor Output be used at the same time?
    What does the Range Adjust knob do?
    Which devices are compatible with the sensor output?

USER’S GUIDE
SA161
Thank you for purchasing the SA161 Dual Expression Pedal. This rugged, cast-aluminum expression pedal
features two independent Expression Outputs as well as a Sensor Output for use with Source Audio
Soundblox effects pedals. The dual TRS expression outputs allows the SA161 to control two Soundblox Pro
(or other 3rd-party ) units simultaneously.
The SA161 outputs are arranged on either side of the pedal. The two outputs have different functionality
and are completely independent circuits.
OUTPUT 1 (right side):
•EXP OUT 1 (TRS): 50 kOhm passive
expression output. Connect to an
expression input on Soundblox Pro or 3rd-
party effects pedals using the included ¼-
inch TRS cable.
•SENSOR OUTPUT: Connect to the SENSOR
INPUT on Soundblox, Soundblox 2,
Soundblox Pro, and Hot Hand effects
pedals. Connect using the included 4-
conductor 3.5mm cable.
OUTPUT 2 (left side):
•EXP OUT 2 (TRS): 50 kOhm passive
expression output.
•RANGE ADJUST: an additional 50 kOhm
adjustment potentiometer is arranged in
series with the EXP OUT 2 potentiometer.
When the knob is fully clockwise, the
range adjust has no effect. The knob can
be turned counter-clockwise to reduce the
range of the EXP OUT 2 pot.
Note: Expression Output and Sensor Output can NOT be
used simultaneously!
