To clean the jacks on your SRD Rockman XP 100 and resolve static or high-low issues with the effects loop, follow these steps:

1. Power Off and Unplug – Turn off the unit and disconnect it from power and any connected cables to prevent electrical damage or shock.

2. Access the Jacks – If necessary, remove the back cover or casing to access the internal jacks. Use a screwdriver if required.

3. Inspect for Debris or Oxidation – Check the jacks for dust, dirt, or oxidation, which can cause connection issues.

4. Use Contact Cleaner – Spray a small amount of electronic contact cleaner (such as DeoxIT) into the jacks. Insert and remove a plug multiple times to help distribute the cleaner and remove contaminants.

5. Clean with a Cotton Swab or Brush – If oxidation is present, use a cotton swab or soft brush lightly dampened with contact cleaner to scrub the inside of the jacks.

6. Check for Loose Connections – Inspect solder joints and connections for any loose or broken wires. Resolder if necessary.

7. Let It Dry – Allow the cleaner to evaporate completely before reassembling and powering on the unit.

8. Test the Jacks – Reconnect your cables and test the effects loop to ensure the static or signal drop issue is resolved.

Repeat the process if needed, and consider using a jack plug cover when not in use to minimize future contamination.

Please ignore the name of who I sent it to and the cost for some repairs that I had this man do. Thanks

Hello Dwight. I hope this email finds you feeling well. I sent you a text message back on the 11th of February asking you if the $45 dollars was the correct amount for my last work you did for me and shipping? Never heard back from you, so I hope it was? Also, I have a question for you regarding my Rockman XP100 that you have worked on for me before. I have been connecting my other modules through its effects loop on the back of it and when I push in the little front panel effects loop switch it kills the sound of everything and if it doesn’t kill the sound it is a lower sound in volume that is really crackly and staticky. Before I connected the (3) equalizers, stereo echo, stereo chorus stereo chorus delay and smart gate. It was working great with only (1) equalizer, stereo echo, stereo chorus, stereo chorus delay and smart gate, but I think something has happened. If I send it to you, what all will I need to send? The last time I sent you the pre amp, which was the front control panel and the power amp section. Remember I have these built into a Rockman XP212 amplifier 2 x 12 speaker cabinet now. Thanks and hope to hear from you soon, Dennis

The SRD Rockman XP 100 may experience sound issues when using the effects loop due to several possible causes:

1. Faulty Effects Loop Jacks – The send and return jacks may have oxidation or wear, causing poor connections. Cleaning or replacing these jacks may resolve the issue.

2. Defective Send/Return Buffer Circuit – The circuit responsible for handling signals in and out of the effects loop could be damaged, leading to signal loss or distortion.

3. Bad Op-Amps or Capacitors – The effects loop circuitry often relies on operational amplifiers and capacitors that can degrade over time, affecting sound quality.

4. Loose or Broken Solder Joints – Connections on the circuit board may become loose, leading to intermittent or weak signals.

5. Impedance Mismatch or External Effects Issues – If the connected effects pedal or processor has an impedance mismatch, it may cause volume drops or tonal issues.

### Parts to Send for Repair:
- Effects loop send/return jacks if they are physically damaged or corroded.
- Op-amps and capacitors in the effects loop circuit if they are faulty.
- The mainboard or effects loop PCB if the issue is traced to internal circuitry damage.

Before sending parts for repair, checking for loose connections, cleaning the jacks, and testing with different cables and effects units is recommended.
