Source Audio Dual Expression Pedal

Source Audio Dual Expression Pedal

MIDI Interface / Port Expander

The Source Audio Dual Expression Pedal delivers precision response and smooth action in a durable cast aluminum housing. Dual TRS expression outputs make it possible to control two effects units simultaneously. The pedal is compatible with the very common Boss/Roland style (“tip hot”) expression input. The Range Adjust Knob sets the bottom point of the expression range. Plus, a special Sensor Output connects directly to any Hot Hand®, Soundblox®, Soundblox 2, or Soundblox Pro pedal for real-time control over filter sweeps, effect modulation, LFO speeds, wet/dry mixes, drive levels and more.

Main Features:

• Dual Expression Pedal
• Expression pedal for controlling 2 EXP enabled effects pedals or one EXP enabled effects and one Source Audio Soundblox, Soundblox2, Soundblox Pro, Hot Hand Effects pedal.
• 50k Ohm passive expression outputs
• Compatible with tip-hot (+) expression inputs used by most manufacturers
• Left side outputs (not usable simultaneously):
  • 50k Ohm passive 6.3 mm TRS Expression Output – for controlling EXP enabled effects pedals
  • Source Audio 3.5 mm TRS Sensor Output – for controlling Source Audio Soundblox, Soundblox2, Soundblox Pro or One Series Effects pedal.
• Right side output:
  • 50k Ohm passive 6.3 mm TRS Expression Output with Range potentiometer – for controlling EXP enabled effects pedals for adjusting this output’s range
• No power required

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 3^rd party 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.

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.
