2. Pomembna varnostna navodila
To prevent fire, electric shock, or product damage, always follow these basic precautions:
- Preberite vsa navodila.
- Te naprave ne uporabljajte v bližini vode.
- Čistite samo s suho krpo.
- Ne blokirajte prezračevalnih odprtin. Namestite v skladu z navodili proizvajalca.
- Ne nameščajte v bližini virov toplote, kot so radiatorji, grelniki, peči ali druge naprave (vključno z amplifiers), ki proizvajajo toploto.
- Ne izničite varnostnega namena polariziranega ali ozemljenega vtiča.
- Zaščitite napajalni kabel, da se po njem ne pohodi ali stisne, zlasti pri vtičih, vtičnicah in na mestu, kjer izstopa iz naprave.
- Uporabljajte samo priključke/dodatke, ki jih je določil proizvajalec.
- Izklopite napravo med nevihtami ali ko je dlje časa ne uporabljate.
- Za vse servise se obrnite na usposobljeno servisno osebje. Servis je potreben, če je bil aparat kakor koli poškodovan, na primer poškodovan je napajalni kabel ali vtič, je bila polita tekočina ali so v aparat padli predmeti, je bil aparat izpostavljen dežju ali vlagi, ne deluje normalno , ali je bil opuščen.

4. Navodila za namestitev
Razpakiranje
Previdno odstranite amplifier from its packaging. Inspect for any signs of damage. Retain the packaging for future transport or storage.
Umestitev
Postavite amplifier on a stable, flat surface. Ensure adequate ventilation around the unit to prevent overheating. Do not cover ventilation openings.
Napajalni priključek
AC napajanje
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.
Povezovanje zvočnikov
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.
Povezovanje vhodnih naprav
Mikrofoni
Connect microphones to the MIC 1-6 input jacks on the front panel.
Pomožne naprave
Connect auxiliary audio sources (e.g., CD player, media player) to the AUX inputs.
External Mixer / Booster Amplifier
Use the LINE IN for connecting an external mixer. Use the PREAMP OUT or LINE OUT to connect to a booster ampnaprava za vžig ali snemanje.
5. Upravljanje vašega Amplifier
Vklop
Ensure all connections are secure and input levels are set to minimum. Press the POWER switch on the front panel to turn on the ampindikator POWER bo zasvetil.
Prilagajanje vhodnih ravni
Gradually increase the individual MIC/AUX Level Controls for the active input channels until the desired volume is achieved. Monitor the OUTPUT LEVEL indicators to avoid clipping.
Glavni nadzor glasnosti
Use the MASTER Volume control to adjust the overall output volume of the amplifier.
Prilagoditev tona
