6. Funtzionamendu-argibideak
6.1 Piztu/Itzaltzea
The amplifier will power on automatically when the remote turn-on lead receives a signal from your head unit. The 'PWR' LED indicator will illuminate. The amplifier features a soft turn-on/turn-off circuit to prevent audible pops.
6.2 Bluetooth audio erreprodukzioa
Audioa haririk gabe erreproduzitzeko:
- Ziurtatu ampargitzailea piztuta dago.
- Aktibatu Bluetooth-a zure gailu mugikorrean (smartphone-a, tableta, etab.).
- Bilatu available Bluetooth devices and select 'Lanzar HTG668BT' (or similar name) to pair.
- Behin parekatuta, audioa zuzenean erreproduzitu dezakezu ampbiziagoa.
6.3 Audio ezarpenak doitzea
Erabili kontrolak amplifier's front panel (refer to Image 5.3) to fine-tune your audio:
- Irabazi-kontrolak: Adjust the input sensitivity to match the output level of your head unit. Start with the gain at minimum and slowly increase until desired volume is achieved without distortion.
- Pasabide baxuko iragazkia (LPF): Use this filter to allow only frequencies below the set point to pass through, typically used for subwoofers. Adjustable from 40Hz-250Hz.
