4. Setup Guide
Kuburitsa
Ngwarira kubvisa iyo amplifier from its packaging. Inspect for any signs of damage. Retain the packaging for future transport or storage.
Placement
Place the amplifier on a stable, flat surface. Ensure adequate ventilation around the unit to prevent overheating. Do not cover ventilation openings.
Power Connection
AC Simba
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.
Kubatanidza Vatauri
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.
Kubatanidza Input Devices
Maikorofoni
Connect microphones to the MIC 1-6 input jacks on the front panel.
Mazano Ebetsero
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 amplifier kana midziyo yekurekodha.
5. Operating Your Amplifier
Powering On
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.
Kugadziridza Mahwanda Ekuisa
