Sinbosen D series digital power amplifier bridge function - Sinbosen| Audio sound system manufacturer

The function of bridge connection in power amplifiers:

- Enhance output power: In bridge mode, the output voltage of the two channels of the power amplifier is added together, doubling the output voltage. Theoretically, this can increase the output power to four times the original. In practice, due to the impedance of the speakers and the non-ideal characteristics of the amplifier, the increase in output power is usually between two to three times.

- Drive low impedance loads: Bridge mode allows the power amplifier to drive low impedance speaker systems, which is very useful for occasions that require high power output, such as large-scale performances and conferences.

- Simplify system configuration: In some cases, using bridge mode can reduce the number of amplifiers required, simplifying the system configuration.

Precautions for bridging:

- Speaker impedance: In bridge mode, the impedance of the speaker is halved. Therefore, it is necessary to ensure that the speaker can withstand the power after bridging.

- Speaker matching: When bridging, it is best to use speakers of the same model and specifications to ensure balanced loads on both channels.

- Amplifier protection: In bridge mode, the thermal protection and short-circuit protection of the amplifier may require special attention, as the output power of the amplifier increases in bridge mode, which may lead to overheating.

- Operation safety: Bridging operation requires professional knowledge and correct wiring. Improper operation may lead to equipment damage or safety accidents.

- Sound quality impact: Although bridge mode is mainly used to increase power output, it may also have a certain impact on sound quality, especially when outputting at high power.

Steps for bridging operation:

- Set up the amplifier: Set the amplifier to bridge mode. This usually involves switching switches or settings on the back panel or control panel of the amplifier.

- Wiring: Correctly connect the speaker and amplifier. In bridge mode, the positive pole of the speaker is connected to the positive pole of one channel of the amplifier, and the negative pole is connected to the positive pole of the other channel.

- Testing: After the connection is completed, test to ensure that the system works normally and there is no overheating or other problems.

- Monitoring: When running in bridge mode, it is necessary to closely monitor the temperature of the amplifier and the state of the speaker to ensure safety and performance.
