5.2 Ogwe azụ gafereview na njikọ

Image 2: Rear panel of the Atlas Sound PA40G amplifier, displaying Balanced Input, Left In/Right In (Summed Inputs), Speaker Out, and the AC power inlet.
- Ntinye ziri ezi: Connect a balanced line-level audio source using the provided Phoenix connector. This input is typically used for professional audio equipment.
- Left In / Right In (Summed Inputs): Connect an unbalanced stereo line-level audio source (e.g., from a media player or mixer) using RCA cables. These inputs are summed to mono internally.
- Apụọ: Connect your 70V or 100V constant voltage speaker system using the provided Phoenix connector. Ensure correct polarity and secure connections.
- Ntinye ike AC: Connect the supplied power cord to this inlet and then to a suitable AC power outlet (100VAC-240VAC, 50/60 Hz).
- Ọdụ ụgbọ ala: Provides an optional connection point for system grounding if required.
5.3 Nzọụkwụ nwụnye
- Ịkwanye: The PA40G is designed for surface mounting or can be placed on a shelf. Ensure adequate ventilation around the unit.
- Connect Inputs: Connect your audio source(s) to either the Balanced Input or the Summed Inputs (Left In/Right In) on the rear panel.
- Jikọọ ndị ọkà okwu: Connect your 70V or 100V speaker system to the Speaker Out terminal. Verify that the total wattage of your speakers does not exceed the amplifier's 40W output.
- Njikọ Ike: Gbaa mbọ hụ na amplifier's gain control is set to minimum. Connect the power cord to the AC Power Inlet and then to a grounded electrical outlet.
6. Ntuziaka ọrụ
- Ike Na: Once all connections are secure, turn on the power to the amplifier. The Power LED on the front panel will illuminate.
- Gbanwee uru: Slowly increase the Gain control knob on the front panel to achieve the desired output volume. Monitor the Signal and Limit LEDs.
- Nyochaa LEDs:
- Nke Signal LED indicates the presence of an audio signal.
- Nke Oke LED indicates that the amplifier is operating near its maximum output. If this LED flashes frequently or stays lit, reduce the input signal level or the amplifier's gain to prevent distortion and potential damage.
- Gbanyụọ: Iji gbanyụọ amplifier, simply disconnect the power cord from the AC outlet.
7. Nlekọta
- Nhicha: Hichaa mpụta nke amplifier with a soft, dry cloth. Do not use liquid cleaners or solvents.
- Igwe ikuku: Ensure that the ventilation openings are clear of dust and obstructions to prevent overheating.
- Nyocha: Periodically check all cable connections for security and signs of wear.
