- Input tal-Enerġija AC: Connects to 220-240V AC mains supply.
- Input ta' Enerġija DC: Terminals for 12V DC car battery connection. Observe polarity (+/-).
- DC FUSE: T 6A L fuse for DC power protection.
- Riżultati tal-Ispeaker: Screw terminals for connecting speakers. Options include COM (Common), 4Ω, 8Ω, 16Ω, and 100V line output.
Setup
1. Unboxing u Spezzjoni
Neħħi bil-galbu amplifier from its packaging. Inspect the unit for any signs of damage. Ensure all components are present.
2. Konnessjoni tal-Enerġija
The UB-30 can be powered by either AC mains or a 12V DC battery.
- 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.
- 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.
Attenzjoni: Dejjem tiżgura l- amplifier is switched OFF before connecting or disconnecting power sources.
3. Konnessjoni tal-Ispeaker
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.
- Connect the common (negative) terminal of your speaker(s) to the COM terminal fuq il - ampaktar ħaj.
- Connect the positive terminal of your speaker(s) to the 4Ω, 8Ω, jew 16Ω terminal, matching your speaker's impedance.
- For 100V line speakers, connect to the 100V terminali u COM. Ensure your speakers are compatible with 100V line systems.
Importanti: Do not connect speakers to multiple impedance terminals simultaneously. Ensure all connections are secure.
4. Input Device Connection
- Mikrofoni: Qabbad il-mikrofoni mal- MIC-1 u/jew MIC-2/AUX 6.3mm input jacks on the front panel.
- Apparati Awżiljarji: Connect audio sources like smartphones, CD players, or laptops to the MIC-2/AUX input jack using an appropriate cable.
Istruzzjonijiet Operattivi
1. Tixgħel
- Ensure all volume controls (MIC-1, MIC-2/AUX) are set to their minimum position (fully counter-clockwise).
- Agħfas il- QAWWA switch on the front panel to the 'ON' position. The power indicator light will illuminate.
2. Volum ta 'aġġustament
- For MIC-1, slowly turn the Kontroll tal-Volum MIC-1 clockwise until the desired sound level is achieved.
- For MIC-2 or AUX input, slowly turn the MIC-2/AUX Volume Control clockwise until the desired sound level is achieved.
- Avoid setting the volume too high, which can cause distortion or damage to speakers.
3. Aġġustament tat-Ton
Uża l- Kontroll tat-TON knob to adjust the frequency response of the amplifier. Turning it towards 'CUT' will reduce higher frequencies (treble), while turning it towards 'FLAT' will provide a more balanced, full-range sound.
4. Itfi
- Turn all volume controls to their minimum position.
- Agħfas il- QAWWA switch to the 'OFF' position. The power indicator light will turn off.
Manutenzjoni
Tindif
Imsaħ il-barra tal- amplifier with a soft, dry cloth. Do not use liquid cleaners or abrasive materials, as they may damage the finish or internal components.
Fuse Replacement (DC Fuse)
Jekk il- amplifier fails to power on when using DC battery power, the DC fuse may need replacement. The fuse is located on the rear panel.
- Importanti: Disconnect all power sources (AC and DC) before attempting to replace the fuse.
- Unscrew the fuse holder cap on the rear panel.
- Remove the old fuse and replace it with a new fuse of the same type and rating (T 6A L).
- Securely screw the fuse holder cap back into place.
Attenzjoni: Always replace fuses with the specified type and rating to prevent damage to the amplifier or risk of fire.
