Recently, customers have provided feedback that the DS-10Q has a red dot that lights up abnormally after turning it on. They have been worried that it might be malfunctioning and asked if it could damage the amplifier. In reality, the illuminated light is normal. This change occurred only this year, and the red dot indicates that the power supply board is functioning. It will facilitate engineers in determining if the power supply is working properly and help identify any issues with the amplifier. Therefore, customers who have recently purchased the amplifier should not worry if they encounter this situation, as it is a normal operating state.

Customers who are familiar with our company know that the DS series power amplifiers from Sinbosen are our best-selling products. However, recently Sinbosen has upgraded the DS series power amplifiers. Models like DS-10Q and DS-14K have added fans on the rear panel, while DS-20Q and DS-22Q have built-in small fans at the back.

What are the advantages of having a built-in fan in the rear panel?

Improved heat dissipation: The built-in fan can dissipate heat more effectively, helping to prevent the amplifier from overheating and improving the stability and lifespan of the equipment.

Reduced noise level: The built-in fan can be better integrated into the design of the device, reducing potential noise generation.

Neater appearance: Moving the fan to the inside can make the rear panel look neater, avoiding the need to add additional components externally.

Reduced risk of damage: Having the fan built-in to the rear panel may reduce the risk of external components being damaged. External fans are more susceptible to physical damage, while built-in fans are relatively safer.

Better airflow design: By designing with a built-in fan, it can work in synergy with the overall airflow design of the device, improving heat dissipation effectiveness.
