3. Setup

3.1 Tuner Pedal Setup

Power Connection: Connect a standard 9V DC power supply (center negative, not included) to the 'DC 9V' input jack on the tuner pedal.
Input Connection: Connect your guitar or bass to the 'INPUT' jack on the tuner pedal using a standard 1/4-inch instrument cable.
Output Connection: Connect the 'OUTPUT' jack of the tuner pedal to your amplifier or the input of your next effect pedal in the signal chain using a standard 1/4-inch instrument cable.

3.2 SPS-20 Guitar Power Supply Setup

Main Power Connection: Connect the included AC power cable to the 'AC IN' port on the SPS-20 power supply and plug the other end into a wall outlet (100-240V, 50/60Hz).
Pedal Connections: Identify the voltage and current requirements for each of your effect pedals.
Connect DC Outputs: Use the provided DC cables to connect your pedals to the appropriate isolated DC output ports on the SPS-20 (e.g., 9V 100mA, 9V 500mA, 12V 100mA, 18V 100mA). Ensure the polarity matches your pedals (center negative is standard for most guitar pedals).
Connect AC Outlets: For devices requiring AC power, plug them into the 4 top AC outlet socket holes. Ensure the total power consumption does not exceed 600W.

4. Operating Instructions

4.1 Using the Tuner Pedal

Power On/Off: Press the footswitch to engage or disengage the tuner. When engaged, the display will light up, and your instrument's signal will be muted for silent tuning. When disengaged, the true bypass circuit ensures your signal passes through unaffected.
Tuning Process:
- Pluck a single string on your instrument.
- The large color screen will display the detected note (e.g., 'A', 'E', 'G') and an indicator showing if the note is flat, sharp, or in tune.
- Adjust your instrument's tuning peg until the indicator is centered and the display shows the note is 'in tune'. The display will typically turn green when in tune.
- Repeat for all strings.
A4 Calibration: The tuner supports A4 calibration from 430Hz to 450Hz. To adjust the A4 reference frequency, refer to the specific controls on the pedal (usually small buttons or a combination of footswitch presses) to cycle through the A4 values. The default A4 is typically 440Hz.

4.2 Using the SPS-20 Guitar Power Supply

Powering On: Once connected to AC power, the blue LED indicators above each DC output port will illuminate, indicating that power is being supplied.
Isolated Outputs: Each DC output is isolated, preventing unwanted noise and hum between pedals. Ensure you use the correct voltage and current output for each pedal to avoid damage.
AC Outlets: The 4 AC outlets function as a standard power strip. Use them for amplifiers, laptops, or other AC-powered devices as needed, ensuring not to exceed the 600W total power limit.

5. Maintenance

Proper maintenance ensures the longevity and optimal performance of your STRICH Tuner Pedal and SPS-20 Guitar Power Supply.

Cleaning: Use a soft, dry cloth to wipe down the units. Do not use abrasive cleaners, solvents, or excessive moisture, as this can damage the finish or internal components.
Storage: Store the units in a cool, dry place away from direct sunlight, extreme temperatures, and high humidity.
Handling: While robust, avoid dropping or subjecting the units to severe impacts. Ensure cables are connected and disconnected carefully to prevent damage to jacks.
Power Supply Care: Regularly check power cables for any signs of wear or damage. Do not overload the AC outlets beyond the specified 600W limit.

6. Troubleshooting

If you encounter issues with your STRICH Tuner Pedal or SPS-20 Guitar Power Supply, please refer to the following common troubleshooting steps:

6.1 Tuner Pedal Issues

Tuner not powering on:
- Ensure the 9V DC power supply is correctly connected and functioning.
- Verify the power supply meets the required specifications (9V DC, center negative).
Inaccurate tuning:
- Ensure you are plucking a single string clearly.
- Check the A4 calibration setting; reset to 440Hz if unsure.
- Ensure your instrument's intonation is correctly set.
No sound when tuner is disengaged (True Bypass):
- Check all cable connections (input, output, amplifier).
- Test with different cables to rule out faulty cables.

6.2 SPS-20 Guitar Power Supply Issues

No power to pedals:
- Ensure the main AC power cable is securely connected to the SPS-20 and the wall outlet.
- Check if the blue LED indicators above the DC outputs are lit. If not, verify the main power connection.
- Ensure each pedal is connected to the correct voltage and current output.
- If a specific output is not working, it might be due to a short circuit. Disconnect all pedals from that output and reconnect one by one to identify the faulty pedal or cable. The isolated protection should prevent other outputs from failing.
Hum or noise in signal:
- While the SPS-20 has isolated outputs, ensure all cables are in good condition and properly shielded.
- Test pedals individually to identify if a specific pedal is introducing noise.
- Ensure no ground loops are present in your overall setup.
AC outlets not working:
- Verify the main power connection to the SPS-20.
- Ensure the total power consumption of devices plugged into the AC outlets does not exceed 600W.
