2. Segurtasun-argibide garrantzitsuak

To prevent fire, electric shock, or product damage, always follow these basic precautions:

• Irakurri argibide guztiak.
• Ez erabili aparatu hau uraren ondoan.
• Garbitu zapi lehor batekin bakarrik.
• Ez blokeatu aireztapen-irekidurak. Instalatu fabrikatzailearen argibideen arabera.
• Ez instalatu bero-iturri inongo ondoan, esate baterako, erradiadoreak, bero-erregistroak, sukaldeak edo beste aparatu batzuk (barne ampberoa sortzen duten argitzaileak).
• Ez zapaldu polarizatutako edo lurreko entxufearen segurtasun-helburua.
• Babestu korronte-kablea oinez ibiltzetik edo atxilotzetik, batez ere entxufeetan, erosotasun-harguneetan eta aparatutik irteten diren puntuetan.
• Erabili soilik fabrikatzaileak zehaztutako eranskinak/osagarriak.
• Deskonektatu aparatu hau tximista-ekaitzetan edo denbora luzez erabiltzen ez duzunean.
• Jarri zerbitzu-zerbitzu guztiak zerbitzu-pertsonal kualifikatuari. Zerbitzua behar da aparatua edozein modutan hondatu denean, hala nola, elikatze-kablea edo entxufea hondatuta dagoenean, likidoa isuri denean edo objektuak aparatura erori direnean, aparatua euria edo hezetasuna jasan duenean, ez du normalean funtzionatzen. , edo erori egin da.

4. Konfigurazio gida

Despaketatzea

Kendu arretaz amplifier from its packaging. Inspect for any signs of damage. Retain the packaging for future transport or storage.

Kokatzea

Jarri amplifier on a stable, flat surface. Ensure adequate ventilation around the unit to prevent overheating. Do not cover ventilation openings.

Potentzia-konexioa

AC potentzia

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.

Bozgorailuak konektatzea

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.

Sarrera-gailuak konektatzea

Mikrofonoak

Connect microphones to the MIC 1-6 input jacks on the front panel.

Gailu Laguntzaileak

Connect auxiliary audio sources (e.g., CD player, media player) to the AUX inputs.

External Mixer / Booster Ampbiziagoa
