2. Treoracha Tábhachtacha Sábháilteachta
To prevent fire, electric shock, or product damage, always follow these basic precautions:
- Léigh na treoracha go léir.
- Ná húsáid an gaireas seo in aice le huisce.
- Glan ach amháin le éadach tirim.
- Ná bac aon oscailtí aerála. Suiteáil de réir threoracha an mhonaróra.
- Ná suiteáil in aice le haon fhoinsí teasa cosúil le radaitheoirí, cláir teasa, soirn, nó gaireas eile (lena n-áirítear ampleachtaitheoirí) a tháirgeann teas.
- Ná scrios an cuspóir sábháilteachta atá ag an breiseán polaraithe nó cineál talaimh.
- Cosain an téad cumhachta ó bheith ag siúl air nó á phionnadh, go háirithe ag plocóidí, gabhdáin áise, agus an pointe a dtéann siad amach as an ngaireas.
- Ná húsáid ach ceangaltáin/gabhálais atá sonraithe ag an monaróir.
- Díphlug an gaireas seo le linn stoirmeacha tintreach nó nuair nach bhfuil sé in úsáid ar feadh tréimhsí fada ama.
- Déan gach seirbhísiú a tharchur chuig pearsanra seirbhíse cáilithe. Tá gá le seirbhísiú nuair a dhéantar damáiste don ghaireas ar bhealach ar bith, amhail corda soláthair cumhachta nó breiseán damáiste, doirteadh leacht nó rudaí tar éis titim isteach sa ghaireas, bhí an gaireas faoi lé báisteach nó taise, ní oibríonn sé de ghnáth. , nó gur thit.

4. Treoir Socraithe
Díphacáil
Bain an amplifier from its packaging. Inspect for any signs of damage. Retain the packaging for future transport or storage.
Socrúchán
Cuir an amplifier on a stable, flat surface. Ensure adequate ventilation around the unit to prevent overheating. Do not cover ventilation openings.
Ceangal Cumhachta
Cumhacht 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.
Cainteoirí a Nascadh
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.
Ag Ceangal Gléasanna Ionchuir
Micreafóin
Connect microphones to the MIC 1-6 input jacks on the front panel.
Gléasanna Cúnta
Connect auxiliary audio sources (e.g., CD player, media player) to the AUX inputs.
External Mixer / Booster Amplitheoir
Use the LINE IN for connecting an external mixer. Use the PREAMP OUT or LINE OUT to connect to a booster ampardaitheoir nó trealamh taifeadta.
5. Operating Your Amplitheoir
Cumhachtú Ar
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.
Leibhéil Ionchuir a Choigeartú
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.
Máistir-Rialú Imleabhar
Use the MASTER Volume control to adjust the overall output volume of the amplitheoir.
Coigeartú Ton
