Here are some common precautions for using the 1500 amplifier:

Connection:

- Make sure to connect speakers and other devices in a power-off state, and connect the speaker wires according to the correct positive and negative markings to avoid short circuits.

- When connecting the signal wire, plug it tightly to ensure stable signal transmission and match it with the corresponding input and output interfaces.

power supply:

- Use a standard power supply voltage that meets the requirements of the amplifier to avoid damage to the equipment due to excessive or low voltage.

- Try to avoid sharing sockets with other high-power electrical appliances to prevent voltage fluctuations and other situations.

Usage environment:

- Place it in a well-ventilated place to facilitate heat dissipation, avoid working in a high temperature environment for a long time, and prevent components from overheating and damage.

- Stay away from humid and dusty environments to prevent circuit failures.

Operation:

- Turn on the audio source device first, then the amplifier; the shutdown order is the opposite to prevent instantaneous current shock from damaging the equipment.

- Adjust the volume step by step, and avoid turning the volume too high at once to avoid howling or damage to the speaker.

Maintenance:

- Clean the dust on the surface of the amplifier regularly to keep it clean and tidy.

- When not in use for a long time, you can power it on for a short period of time to prevent the components from getting damp.
