8.1 No Sound from RCA Input

If you are not getting sound from the RCA input, check the following:

• The A08 PRO prioritizes Bluetooth input. If a previously paired Bluetooth device is within range and has its Bluetooth enabled, the amplifier may automatically connect to it, overriding the RCA input.
• To switch to RCA input, ensure no Bluetooth device is actively paired with the A08 PRO. You may need to manually disconnect or turn off Bluetooth on your source device (e.g., smartphone) to force the amplifier to switch to RCA.
• Verify that the RCA cables are securely connected to both the amppenghidup dan sumber audio.
• Semak tahap kelantangan pada kedua-dua amplifier dan sumber audio anda.
