- Analog Input: Connect your analog audio source (e.g., turntable preamplifier, tape deck, mixer) to the 'RIGHT IN' and 'LEFT IN' RCA jacks on the rear panel. Ensure correct channel orientation.
- Digital Output: Connect the JOPLIN ADC to your digital audio receiver, DAC, or computer's digital input using one of the following outputs:
- AES/EBU Out: For professional balanced digital audio connections.
- S/PDIF Out: For coaxial digital audio connections.
- Toslink Out: For optical digital audio connections.
- USB Connection: Connect the JOPLIN ADC to your computer using the provided USB cable. The USB 2.0 port allows for high-speed data transfer for digital audio.
- Power Connection: Connect the external 15V DC power supply to the 'DC IN 15VDC' port on the rear panel. Plug the power supply into a suitable AC outlet.
Operating Instructions
1. Powering On/Off
After all connections are made, power on your audio source and receiving device. Then, connect the JOPLIN ADC's power supply to an AC outlet. The unit will power on automatically. To power off, simply disconnect the power supply.

2. Front Panel Controls and Display
The front panel features a digital display that shows the current sampling rate of the converted audio signal (e.g., 192 for 192kHz). There is also a small button and a larger knob, likely for input selection or menu navigation.
Figure 3: The M2TECH remote control, featuring buttons for power, menu/escape, navigation (up, down, left, right, OK), and potentially other functions for controlling the JOPLIN ADC.
3. Remote Control Functions
The included remote control provides convenient access to the JOPLIN ADC's functions. Use the directional buttons and 'OK' to navigate menus and select options. The 'MENU/ESC' button allows you to access the unit's settings or exit current menus. The power button on the remote can be used to toggle the unit's standby mode.
Maintenance
Cleaning
To maintain the appearance and performance of your JOPLIN ADC, follow these cleaning guidelines:
- Always disconnect the power supply before cleaning.
- Use a soft, dry, lint-free cloth to wipe the exterior surfaces.
- For stubborn marks, slightly dampen the cloth with water. Do not use harsh chemicals, abrasive cleaners, or solvents, as these can damage the finish.
- Avoid spraying liquids directly onto the unit.
General Care
- Do not block the ventilation openings.
- Protect the unit from extreme temperatures and humidity.
- Avoid dropping or subjecting the unit to strong impacts.
Troubleshooting
If you encounter issues with your M2TECH JOPLIN ADC, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No power/Unit does not turn on | Power cable not connected; Power outlet faulty; Power supply damaged. | Ensure power supply is securely connected to the unit and a working outlet. Test the outlet with another device. Contact support if power supply is suspected to be faulty. |
| No audio output | Incorrect input/output connection; Wrong input selected on receiving device; Source device not playing audio. | Verify all analog and digital audio cables are correctly connected. Ensure the correct input is selected on your amplifier or DAC. Confirm the audio source is active and playing. |
| Distorted or noisy audio | Poor cable connection; Interference; Source signal too strong/weak. | Check all cable connections for looseness or damage. Ensure cables are not running parallel to power cords. Adjust the output level of your analog source if possible. |
| Display not showing correct sample rate | Source signal issue; Unit malfunction. | Verify the analog source is providing a stable signal. Try restarting the JOPLIN ADC by disconnecting and reconnecting power. |
If the problem persists after trying these solutions, please contact M2TECH customer support or your authorized dealer.
