FAQs
Q: Can I import custom images, animations, or display interfaces?
A:
No. TX7 uses built-in display styles and does not support user-imported images, animations, or custom interfaces.
Q: Can I use TX7 with my current audio system?
A:
Yes. Use the included 3.5 mm splitter cable to send one signal to TX7 and the other to your existing audio system.
Q: Why is there no VU or spectrum movement?
A:
Check that the correct input source is selected. For AUX, confirm the cable connection and raise the source volume if needed. For MIC pickup, move TX7 closer to the speaker or increase the gain.
Q: Why does the spectrum still move when no audio is playing?
A: High gain, device noise, cable interference, or ambient sound picked up by the MIC may cause movement. Lower the gain or run noise-floor calibration to reduce unwanted activity.
Q: Why do the two VU meters move differently?
A: In AUX Line Input mode, dual VU meters display the left and right channels separately. Mono sources, uneven channel levels, poor cable contact, or mono adapters can cause different movement or activity on only one side.
