The following is troubleshooting information if you're having problems when using the MIX IN input on the TD-25.
The MIX IN on the TD-25 is a stereo 1/8"(3.5mm) input. This means you must use a stereo cable when connecting to it if you want to hear both left and right sides (stereo) from your audio source.
- If you're having to use an adapter on the end of the cable to compensate for the 3.5mm size of the MIX IN jack, try a different adapter. Make sure the adapter is stereo.
- Check both ends on the cable that you're using and make sure there are two black lines on each end. This would indicate a stereo cable.
- When connecting a Phone /iPod/iPad, etc., be sure to remove any protective case that you may have on the device. Cases can prevent certain cables from inserting all the way into the headphone output on the device, which can cause problems.
- The MIX IN is designed for line level and/or headphone output signals only. *Never* connect a powered output (from a power amplifier or powered monitor feed) to the MIX IN jack. Doing so will damage the TD-25's MIX IN.
- If you're hearing distortion from the MIX IN signal, lower the output volume on the external connected device (e.g. headphones volume), lower the AUDIO IN Gain setting within the TD-25 (MENU > SETUP > AUDIO).
