Source Audio SA161 Dual Expression Pedal User Manual

Introduction

The Source Audio SA161 Dual Expression Pedal provides precise response and smooth action within a durable cast aluminum housing. It features dual TRS expression outputs, enabling simultaneous control over two effects units. This pedal is compatible with any effect unit that includes a TRS expression input. Additionally, a dedicated Sensor Output allows direct connection to any Hot Hand, Soundblox, Soundblox 2, or Soundblox Pro pedal for real-time control over various parameters such as filter sweeps, effect modulation, LFO speeds, wet/dry mixes, and drive levels.

Key Features

• Two Isolated TRS Expression Outputs: Allows simultaneous control over multiple effect pedals or rack systems.
• Sensor Output: A 1/8-inch, four-conductor output compatible with all Soundblox, Soundblox 2, or Soundblox Pro pedals.
• Rugged Construction: Housed in a durable, cast aluminum enclosure.

Right Side Connections

• SENSOR OUTPUT: This 1/8-inch, 4-conductor jack is designed to connect directly to the SENSOR INPUT of all Soundblox, Soundblox 2, or Hot Hand pedals.
• OUTPUT 1: This is a 1/4-inch TRS Passive Expression Output. Connect this to the expression input of your first effects unit.

Left Side Connections

• OUTPUT 2: This is a 1/4-inch TRS Passive Expression Output. Connect this to the expression input of your second effects unit.
• RANGE ADJUST: This knob allows you to adjust the minimum (heel-down) position of the expression signal for OUTPUT 2. Turn the knob to set the desired bottom point of the expression range.

Operating Instructions

Basic Operation

Once connected, the SA161 pedal functions like a standard expression pedal. Pressing the pedal forward (toe-down) increases the expression value, while rocking it back (heel-down) decreases the value. The specific parameter controlled (e.g., volume, wah, modulation speed) depends on the settings of the connected effects unit.

Range Adjustment

The RANGE ADJUST knob on the left side of the pedal is specifically for OUTPUT 2. This knob sets the heel-down (minimum) value of the expression sweep for the second output. To adjust, rock the pedal to the heel-down position and turn the RANGE ADJUST knob until the desired minimum effect is achieved on your connected device. This allows for fine-tuning the sweep range to suit your specific needs.

Maintenance

To ensure the longevity and optimal performance of your Source Audio SA161 Dual Expression Pedal, follow these maintenance guidelines:

• Cleaning: Wipe the pedal with a soft, dry cloth. Avoid using abrasive cleaners or solvents, as these can damage the finish and internal components.
• Storage: Store the pedal in a dry environment, away from extreme temperatures and humidity.
• Cable Management: Ensure all cables are connected securely but without excessive strain. Avoid sharp bends or kinks in the cables.
• Inspection: Periodically check for any loose screws or connections. Do not attempt to disassemble the pedal beyond what is necessary for routine maintenance or authorized repairs.

Troubleshooting

If you encounter issues with your SA161 Dual Expression Pedal, consider the following troubleshooting steps:

• No Response from Effects Unit:
  • Ensure the TRS cable is fully inserted into both the expression pedal and the effects unit.
  • Verify that the effects unit is configured to accept expression pedal input and that the correct parameter is assigned.
  • Test with a different TRS cable to rule out cable failure.
• Inconsistent or Limited Sweep Range:
  • For OUTPUT 2, adjust the RANGE ADJUST knob on the left side of the pedal to set the desired minimum value.
  • Check the settings on your effects unit; some units have their own expression range calibration.
• Pedal Not Staying in Heel-Down Position:
  • This can sometimes be an issue with certain effects units that require a specific resistance at the heel-down position. Consult your effects unit's manual.
  • Ensure the pedal's internal mechanism is free from obstructions.
• Scratchy or Uneven Movement:
  • Over time, dust or debris can affect the pedal's mechanism. Gentle cleaning may resolve this.
  • If the issue persists, contact Source Audio support for assistance.
