6. Persediaan

6.1. Sambungan Bekalan Kuasa

The ZK-1002Q requires a DC power supply between 12V and 24V. The DC power input jack typically requires a 5.5mm x 2.5mm or 5.5mm x 2.1mm barrel plug. Ensure your power adapter meets these specifications. An adapter with insufficient voltage or current may lead to poor performance or non-functionality. A 12V 5A or 24V 5A adapter is generally recommended for optimal performance.

6.2. Sambungan Pembesar Suara

Connect your passive speakers to the speaker output terminals. Use the provided screwdriver to loosen the terminals, insert the speaker wires (positive to positive, negative to negative), and tighten the screws securely. Ensure no bare wires are touching to prevent short circuits. The amplifier supports speakers with 3-8Ω impedance and up to 100W power per channel.

6.3. Sambungan Input Audio

The amplifier supports two audio input methods:

• Bluetooth: This is the primary wireless input.
• AUX: Use a 3.5mm audio cable to connect an external audio source (e.g., smartphone, MP3 player) to the AUX input jack.

6.4. Microphone Expansion (Optional)

For microphone functionality, connect a compatible microphone preamp board (e.g., ZK-AMP) to the reserved microphone expansion ports. Refer to the diagram for correct wiring. When using the expansion interface, ensure the dial switch on the amplifier is set to the OFF position as indicated in the diagram.
