4.3 Menyambungkan Sumber Audio
- Memastikan ampPemanas elektrik dimatikan dan dicabut daripada plag.
- Connect your audio source (e.g., mixer, preamppenguat) kepada amplifier's input jacks (XLR or 1/4") for Channel A and Channel B. Use high-quality shielded cables to minimize noise.
4.4 Pembesar Suara Penyambung
- Memastikan ampPemanas elektrik dimatikan dan dicabut daripada plag.
- Sambungkan pembesar suara anda ke amplifier's output terminals (Speakon or Banana binding post) for Channel A and Channel B.
- Ensure correct polarity (+ to + and - to -) when using banana binding posts.
- Verify that the impedance of your speakers is compatible with the amplifier's specifications to prevent damage.
4.5 Sambungan Kuasa
- Before connecting the power cord, verify that the voltagsuis pemilih pada panel belakang ditetapkan kepada vol yang betultage untuk kawasan anda (115V atau 230V).
- Sambungkan kord kuasa AC yang dibekalkan kepada amplifier's AC input and then to a grounded electrical outlet.
5. Arahan Operasi
5.1 Menghidupkan/Mematikan
- Hidupkan kuasa: Turn on your audio source devices first, then turn on the EMB PA2400 amplifier using the AC switch on the front panel.
- Matikan: Turn off the EMB PA2400 amplifier first, then turn off your audio source devices. This prevents loud pops or thumps through your speakers.
5.2 Adjusting Volume (Gain)
- Start with the Ch.1 and Ch.2 Gain Knobs set to their minimum position (fully counter-clockwise).
- Mula memainkan audio daripada sumber anda.
- Slowly increase the Gain Knobs for Channel 1 and Channel 2 until the desired volume level is achieved.
- Monitor the LED indicators: The Signal LED should illuminate when audio is present. The Clip LED should only flash occasionally during peak signals. If the Clip LED stays lit, reduce the gain to prevent distortion and potential speaker damage.
6. Penyelenggaraan
6.1 Pembersihan
