- Ensure the power button on the amplifier is pressed.
- Nav skaņas:
- Pārliecinieties, vai ir izvēlēts pareizais ievades avots.
- Pārbaudiet skaļruņu savienojumus, vai ir pareiza polaritāte un vai tie ir droši nostiprināti.
- Ensure the Speaker A/B selector is set to the connected speakers.
- Palieliniet skaļuma līmeni.
- Ja izmantojat austiņas, pārliecinieties, vai tās ir pilnībā ievietotas, un mēģiniet tās izņemt, lai pārbaudītu skaļruņa izejas signālu.
- Verify that all audio cables are securely connected between the source component and the ampdzīvāks.
- Izkropļota skaņa:
- Samaziniet skaļuma līmeni.
- Pārbaudiet skaļruņa impedances saderību ar ampdzīvāks.
- Pārbaudiet audio kabeļus, vai nav bojājumu vai vaļīgu savienojumu.
- Ensure tone controls (Bass/Treble) are not set to extreme levels.
- Dūkšana vai buzz (dūkšana):
- Ensure all ground connections are secure, especially for turntables (SIGNAL GND).
