4. Panduan Persediaan
Membongkar
Buang dengan berhati-hati amplifier from its packaging. Inspect for any signs of damage. Retain the packaging for future transport or storage.
Penempatan
Letakkan amplifier on a stable, flat surface. Ensure adequate ventilation around the unit to prevent overheating. Do not cover ventilation openings.
Sambungan Kuasa
Kuasa 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.
Pembesar Suara Penyambung
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.
Menyambung Peranti Input
Mikrofon
Connect microphones to the MIC 1-6 input jacks on the front panel.
Peranti Pembantu
Connect auxiliary audio sources (e.g., CD player, media player) to the AUX inputs.
External Mixer / Booster Amplebih hidup
Use the LINE IN for connecting an external mixer. Use the PREAMP OUT or LINE OUT to connect to a booster ampalat pengikat atau rakaman.
