Configuració

1. Unboxing i Inspecció

Traieu amb cura amplifier from its packaging. Inspect the unit for any signs of damage. Ensure all components are present.

2. Connexió d'alimentació

The UB-30 can be powered by either AC mains or a 12V DC battery.

1. AC Mains (220-240V): Connect the provided AC power cord to the AC power input on the rear panel and then to a suitable wall outlet.
2. DC Battery (12V): For portable use, connect a 12V car battery to the DC input terminals on the rear panel. Ensure correct polarity: positive (+) to positive, negative (-) to negative.

Precaució: Assegureu-vos sempre el amplifier is switched OFF before connecting or disconnecting power sources.

3. Connexió d'altaveus

Connect your speakers to the appropriate terminals on the rear panel. Match the speaker impedance to the amplifier's output impedance for optimal performance and to prevent damage.

1. Connect the common (negative) terminal of your speaker(s) to the COM terminal al ampmés viu.
2. Connect the positive terminal of your speaker(s) to the 4Ω, 8Ω, o 16Ω terminal, matching your speaker's impedance.
3. For 100V line speakers, connect to the 100 V terminal i COM. Ensure your speakers are compatible with 100V line systems.

Important: Do not connect speakers to multiple impedance terminals simultaneously. Ensure all connections are secure.

4. Input Device Connection

1. Micròfons: Connect microphones to the MIC-1 i/o MIC-2/AUX 6.3mm input jacks on the front panel.
2. Dispositius auxiliars: Connect audio sources like smartphones, CD players, or laptops to the MIC-2/AUX input jack using an appropriate cable.

Instruccions de funcionament

1. Encès

1. Ensure all volume controls (MIC-1, MIC-2/AUX) are set to their minimum position (fully counter-clockwise).
2. Premeu el botó PODER switch on the front panel to the 'ON' position. The power indicator light will illuminate.

2. Ajust de volum

1. For MIC-1, slowly turn the Control de volum MIC-1 clockwise until the desired sound level is achieved.
