Source Audio Toolblox Dual Expression Pedal User Manual

DUAL EXPRESSION PEDAL

USER’S GUIDE

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 3rd­party effects pedals using the included ¼­inch TRS cable.

• SENSOR OUTPUT: Connect to the SENSOR

INPUT on Soundblox, Soundblox 2,
Soundblox Pro, and Hot Hand effects
pedals. Connect using the included 4­conductor 3.5mm cable.

SENSOR OUTPUT

Note: Expression Output and Sensor Output can NOT be
used simultaneously!

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.
