- Lámhleabhar Treoracha (an doiciméad seo)
Note: A 12V power supply is required for operation and is sold separately. Connecting cables are also not included.
3. Socrú
Follow these steps to set up your Kinter MA170 ampleachtaitheoir:
3.1. Ceangal Cumhachta
The MA170 requires a 12V DC power supply. Ensure the power supply has a 2.1 mm x 5.5 mm DC plug with center positive polarity. Connect the power supply to the DC 12V input port on the rear of the amplitheoir.
3.2. Ionchur Fuaime
Connect your audio source (e.g., MP3 player, smartphone, PC, DVD player) to the RCA input jacks (L/R) on the rear of the amplifier. Use appropriate RCA cables for this connection.
3.3. Aschur Cainteora
Connect your speakers to the speaker output terminals on the rear of the amplifier. The MA170 supports speakers with an impedance of 4-16 ohms. Ensure correct polarity (positive to positive, negative to negative) for each speaker. The amplifier provides 2 x 18 watts per channel.
