In addition to passive speakers that need to be used with power amplifiers, Sinbosen also has active speakers that are extremely flexible and cost-effective.Among them, the KA active series is the most popular: KA208 Active (dual 8 inch); KA210 Active (dual 10 inch); KA212 Active (Dual 12 inch). Therefore, many customers also inquire about their built-in active modules. Considering customers' replacement needs or speaker system upgrade needs, Sinbosen launches DM SERIES active board

what is an active speaker system?

Different from passive speakers, active speakers are a sound system that integrates a built-in power amplifier. This design allows them to directly receive audio signals and amplify them without the need for additional external power amplifier equipment, making on-site wiring simpler. This plug-and-play feature greatly improves convenience and efficiency, and is especially suitable for scenarios that require rapid deployment and use, such as temporary events, small performances, or home entertainment systems.

Features of active speakers

Integrated amplifier: The active board in the active speaker integrates an amplifier, so that the speaker can directly receive audio signals and amplify them to drive the speaker unit to produce sound.
Simplified connection: Since the power amplifier function is already built into the speaker, users do not need to purchase and connect additional power amplifiers, which simplifies the construction and use of the sound system.
Save space: The design of the active board can save the space of the sound system, making the speaker more compact and portable.
Cost-Effectiveness: For manufacturers, integrating amplifiers into speakers reduces production costs because the production and packaging of separate amplifiers is eliminated. For users, purchasing active speakers can save the cost of purchasing power amplifiers.
Performance Matching: Active panels are often precisely matched to the speaker units to ensure optimal performance. Manufacturers can design and optimize amplification circuits for specific speaker units to achieve the best sound performance.

What is the key role of active modules (built-in amplifiers) in active systems?

In an active speaker system, the active module (built-in power amplifier) ​​plays a vital role. Active Board is actually a simplified version of a power amplifier built into Active Speaker. It is not only responsible for providing power, but also directly affects the sound quality and performance of the speaker. The matching of active modules and speaker units has been carefully designed to ensure the best sound quality performance. In addition, some high-end active speakers, such as sinbosen's KA active series speakers, also integrate digital signal processing (DSP) technology, which allows the speakers to perform more precise sound adjustments and optimizations to adapt to different acoustic environments and applications. need.

Things to note when installing the amplifier board:

Power matching:
The rated output power of the amplifier should be equal to or greater than the rated power of the speaker. This ensures that the speakers receive sufficient driving power, especially in the mid- to low-frequency range, for a more powerful performance. However, if the rated output power of the power amplifier is much greater than the rated power of the speaker, the volume of the power amplifier needs to be controlled to avoid damage to the speaker.

Impedance matching:
The rated output impedance of the power amplifier should be consistent with the rated impedance of the speaker. This way the amplifier can deliver maximum undistorted power. If the rated impedance of the speaker is greater than the rated output impedance of the power amplifier, the actual output power of the power amplifier will be less than the rated output power. On the contrary, if the rated impedance of the speaker is less than the rated output impedance of the power amplifier, the power amplifier is in danger of overloading.

Dimensions match:
When installing an active power amplifier module, you need to ensure that the size of the power amplifier module matches the installation space of the speaker for correct installation.

Correct connection polarity:
When connecting speakers and power amplifiers, make sure the positive and negative poles correspond correctly to avoid reverse signals affecting your listening experience.
