2. Istruzzjonijiet Importanti dwar is-Sigurtà
To prevent fire, electric shock, or product damage, always follow these basic precautions:
- Aqra l-istruzzjonijiet kollha.
- Tużax dan l-apparat ħdejn l-ilma.
- Naddaf biss b'ċarruta niexfa.
- Timblokkax il-fetħiet tal-ventilazzjoni. Installa skont l-istruzzjonijiet tal-manifattur.
- Tinstallax ħdejn xi sorsi tas-sħana bħal radjaturi, reġistri tas-sħana, stufi, jew apparat ieħor (inkluż amplifiers) li jipproduċu sħana.
- M'għandekx tegħleb l-iskop tas-sigurtà tal-plagg polarizzat jew tat-tip ta 'l-ert.
- Ipproteġi l-korda tad-dawl milli timxi fuqha jew maqrusa, partikolarment fil-plakek, ir-reċipjenti tal-konvenjenza, u l-punt fejn joħorġu mill-apparat.
- Uża biss aċċessorji/aċċessorji speċifikati mill-manifattur.
- Aqla’ dan l-apparat waqt maltempati tas-sajjetti jew meta ma jintużax għal perjodi twal ta’ żmien.
- Irreferi l-manutenzjoni kollha lil persunal tas-servizz kwalifikat. Is-servizz huwa meħtieġ meta l-apparat ikun ġie bil-ħsara b'xi mod, bħal korda tal-provvista tal-enerġija jew plagg ikun bil-ħsara, likwidu jkun inxtered jew oġġetti jkunu waqgħu fl-apparat, l-apparat ikun ġie espost għax-xita jew umdità, ma jaħdimx b'mod normali , jew twaqqgħet.

4. Gwida ta' Setup
Spakkjar
Neħħi bil-galbu amplifier from its packaging. Inspect for any signs of damage. Retain the packaging for future transport or storage.
Pjazzament
Poġġi l- amplifier on a stable, flat surface. Ensure adequate ventilation around the unit to prevent overheating. Do not cover ventilation openings.
Konnessjoni tal-Enerġija
Qawwa AC
Connect the supplied AC power cord to the AC Power Input on the rear panel and then to a suitable wall outlet (240V AC).
DC Power (Battery)
For DC operation, connect a 24V DC car battery to the DC Power Input terminals on the rear panel, observing correct polarity (+ to + and - to -). The amplifier will automatically switch to DC power if AC power fails.
Konnessjoni Kelliema
Connect your speakers to the appropriate Speaker Output Terminals on the rear panel. Ensure the speaker impedance matches the amplifier's output impedance (e.g., 4Ω, 8Ω) or use the 70V/100V constant voltage outputs for compatible PA speaker systems.
Konnessjoni ta 'Tagħmir ta' Input
Mikrofoni
Connect microphones to the MIC 1-6 input jacks on the front panel.
Apparati Awżiljarji
Connect auxiliary audio sources (e.g., CD player, media player) to the AUX inputs.
External Mixer / Booster Ampaktar ħaj
Use the LINE IN for connecting an external mixer. Use the PREAMP OUT or LINE OUT to connect to a booster ampapparat li jirrekordja jew li jirrekordja.
5. It-Tħaddim Tiegħek Ampaktar ħaj
Tixgħel
Ensure all connections are secure and input levels are set to minimum. Press the POWER switch on the front panel to turn on the amplifier. The POWER indicator will illuminate.
