A: Q1 supports Windows 10\/11, macOS, Android, iOS, and audio-focused Linux (e.g. Volumio, ROON). USB connection with phones requires OTG support. No drivers needed for mobile devices, macOs, or Linux. Windows needs a driver only in UAC 2.0 mode. Q: Can I remove the mesh layer on the Q1s top window? A: No. Its a built-in EMI shield to prevent signal interference. Please do not remove it, and keep phones or routers away from the Q1. Q: Can I replace the op-amps in the Q1? A: Yes, the Q1 uses 4PCs pluggable LME49720 op-amps, which can be replaced by standard dual op-amps like 2604\/2134\/muses02 etc. Q: Why dont the single VU meter and spectrum display work properly? A: In single VU meter and spectrum modes, the Q1 only detects the left channel input. If only the right channel is connected, the VU meter and spectrum display will not operate. Q: Why cant I find Q1 in my Bluetooth list? A: Make sure Q1 is set to Bluetooth mode, then turn on Bluetooth on your phone and search for AMPAPA Q1 to connect. If Q1 still doesnt appear, try clearing previous connections using the remote control. Q: Why do the vinyl and tape-style displays spin at a constant speed? A: These two display modes dont react to audio signals, so they simply maintain a constant rotation speed. Even if the music is paused,the rotation continues as long as the mode is engaged. Q: Why does the VU meter show a large deflection at low volume, but a smaller deflection at high volume? A: The Q1 features an automatic gain control system (AGC) for the VU meters. When the input signal is low, the system switches to high gain; when the signal is high, it switches to low gain. This ensures the VU meters maintain sufficient deflection across different volume levels.
