6. Risoluzione Dei Problemi

Per i problemi più comuni e le relative soluzioni, fare riferimento alla seguente tabella:

Fenomeno	Soluzione
Non può essere attivato	Check the power adapter. Only connect the power adapter to a power outlet, not to the unit. If the LED on the adapter blinks or does not light up, the adapter is defective. Controllare il collegamento elettrico.
Nessun suono	The device did not power on. Check LED and the power connection. Check that the proper input source is selected. Press the knob to switch input channel. Check that the proper output channel is selected. Double-press the knob to switch output channel. Controllare le connessioni per tutti i dispositivi. Inserire fino in fondo i cavi di collegamento. Controllare il volume di tutti i dispositivi e verificare che siano disattivati. Ingresso Bluetooth: Too low volume on phone. Please adjust volume. INGRESSO USB: 1) Too low volume on PC. Please check and adjust the computer system volume, music player volume and driver volume. 2) Select the default output device of your music player or computer as this unit.
Suono anomalo	One channel's positive output and negative output may be reversed, please check and correct it. The cables may not be connected correctly, check and reconnect them. Probably overloaded. Try turning down the volume. Potrebbe essere causato da temperature elevate. Spegnere l'unità, attendere che si raffreddi a sufficienza, quindi riaccenderla. Posizionare l'unità in un luogo ben ventilato. Check to see if the problem is with the source, downstream equipment and cables.
Un canale con rumore/nessuna uscita	Check to see if the problem is with the source, downstream equipment and cables. You can try swapping the left and right channel connections.
Squilibrio del canale	Check to see if the problem is with the source, downstream equipment and cables. You can try swapping the left and right channel connections.
Può il amp be used in bridged mode so that it can be used as a mono amp?	IL amplifier is already internally bridged. So no you can't short any of the output terminals together.
Impossibile accoppiare Bluetooth	Abilitare prima la funzione Bluetooth nel menu di configurazione. May be already connected to another Bluetooth device. Press and hold brightness button on the remote control for 3s to let this unit enter pairing mode. Avvicinare il dispositivo Bluetooth a questa unità. Spegnere e riaccendere l'unità, quindi riprovare. Rimuovere le ostruzioni tra il dispositivo Bluetooth e questa unità.
Bluetooth in: l'audio viene interrotto	Per evitare interferenze elettromagnetiche, posizionare questa unità lontano da forni a microonde, dispositivi LAN wireless e altri dispositivi Bluetooth. Ricollegare il dispositivo Bluetooth.
Il dispositivo USB collegato non riconosce questa unità	USB cable did not connect properly. Please check or change the cable. Driver problem. Try to reinstall the driver. Potrebbe essere causato dal PC. Controlla o prova con un altro PC. Alcuni telefoni richiedono prima l'abilitazione della funzione OTG.
Il telecomando non risponde	Abilitare prima la funzione di controllo remoto nel menu di configurazione. Provare a inserire due batterie AAA nuove. Si prega di puntare verso il ricevitore del telecomando. Avvicinare il telecomando al dispositivo. Use your Android phone's camera to look at the transmitter at the top of the remote, if it doesn't blink when you press the remote button, the remote is defective. Se si dispone di più di un dispositivo Topping, verificare di utilizzare il telecomando corretto.
GUADAGNO -1 / GUADAGNO -2	Firmware upgrade failed. Unplug and re-plug the power cable, and then flash the firmware again.
GUADAGNO -3	Incorrect firmware version. Unplug and re-plug the power cable, and then reflash the correct firmware.
PU / P-d	Volume di fornituratage troppo alto/troppo basso. Utilizzare l'adattatore di alimentazione TOPPING.
rd/rr/rA/P-0	Check the power adapter. Only connect the power adapter to a power outlet, not to the unit. If the LED on the adapter blinks or does not light up, the adapter is defective. Scollegare gli altri dispositivi e riavviare. Se il problema persiste, l'unità potrebbe essere difettosa. Contattateci via e-mail.
rh	Vol. DC anomalotage. After changing the song or turning down the volume/gain, unplug and re-plug the power cable and reboot the MX3s.
Frequency of the Subwoofer Output	It is full-band.
