2. Stiùireadh Sàbhailteachd Cudromach
To prevent fire, electric shock, or product damage, always follow these basic precautions:
- Leugh a h-uile stiùireadh.
- Na cleachd an inneal seo faisg air uisge.
- Glan a-mhàin le clò tioram.
- Na cuir bacadh air fosglaidhean fionnarachaidh sam bith. Stàlaich a rèir stiùiridhean an neach-dèanamh.
- Na cuir a-steach faisg air stòran teas sam bith leithid rèididheatoran, clàran teas, stòbhaichean, no uidheam eile (a 'gabhail a-steach ampliifiers) a bheir teas.
- Na dèan a’ chùis air adhbhar sàbhailteachd a’ phlug seòrsa polarized no stèidhichte.
- Dìon an sreang cumhachd bho bhith air a choiseachd air no air a phronnadh, gu sònraichte aig plugaichean, gabhadan goireasachd, agus an àite far am fàg iad bhon inneal.
- Na cleachd ach ceanglachan / goireasan a chaidh a shònrachadh leis an neach-dèanamh.
- Na cuir a-steach an inneal seo aig àm stoirmean dealanach no nuair nach eilear ga chleachdadh airson ùine mhòr.
- Thoir iomradh air a h-uile seirbheis gu luchd-seirbheis le teisteanas. Tha feum air seirbheiseachadh nuair a tha an inneal air a mhilleadh ann an dòigh sam bith, leithid sreang solarachaidh cumhachd no pluga air a mhilleadh, leaghan air a dhòrtadh no nithean air tuiteam a-steach don inneal, tha an inneal air a bhith fosgailte do uisge no taiseachd, chan eil e ag obair gu h-àbhaisteach , no air a chuir sìos.

4. Stiùirich rèiteachaidh
A' dì-phapadh
Thoir air falbh an amplifier from its packaging. Inspect for any signs of damage. Retain the packaging for future transport or storage.
Suidheachadh
Cuir an amplifier on a stable, flat surface. Ensure adequate ventilation around the unit to prevent overheating. Do not cover ventilation openings.
Ceangal cumhachd
Cumhachd 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.
A 'ceangal luchd-labhairt
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.
A 'ceangal innealan cuir a-steach
Micreofon
Connect microphones to the MIC 1-6 input jacks on the front panel.
Innealan Cuideachaidh
Connect auxiliary audio sources (e.g., CD player, media player) to the AUX inputs.
External Mixer / Booster Amplosgadair
Use the LINE IN for connecting an external mixer. Use the PREAMP OUT or LINE OUT to connect to a booster ampuidheamachd lifier no clàraidh.
5. Ag Obrachadh Do Amplosgadair
