What is a U-bridge on an amp? Its position and effect in amply

When using the amp, you can see a small part called a U-bridge plugged into the back. So what is the U-bridge on the amp and what is its position and effect in the amp? Please find out information in the following article of Tnhelearning.edu.vn!

What is a U-bridge on an amp?

The U-bridge on the amplifier is a small and removable component, shaped quite like the letter U. The U-bridge is used to connect the two INPUT and OUTPUT ports side by side.

The U-bridge may or may not be on the amp, depending on the amp manufacturer’s design or the user’s loss of components. Besides, the U-bridge will have different designs depending on the amp line and brand.

Position of the U-bridge on the amp

The U-bridge is located in the INPUT and OUTPUT recording areas next to each other on the right side of the back of the amp.

The U-shaped bridge is usually located on the street marked Effector, next to Music Street.

What does the U-bridge on the amp do?

The U-bridge is responsible for connecting the preamplifier and the amplifier.

Specifically, the preamplifier (Preamplifier) is the place to receive and perform filtering, processing volume and timbre for input signals. Next, the processed sound will be sent to the audio amplifier to amplify the signal to the speaker.

Thus, by connecting the two pre-amplifiers and the amplifiers, the U-bridge helps to adjust the sound in the most optimal way , helping the amp to maximize its use. Without a U-bridge, the pre-amplifier circuit will not be able to handle the sound effects perfectly and the PHONO, TAPE, and REC inputs will not work.

The U-bridge in the amp also works to connect the signal between the amp and the acoustic or mechanical reverberation lines . When the audio signal is transmitted to the amplifier, it will be immediately transferred to the sound filter and then returned directly to the amplifier through the U-bridge to help process the sound more fully.

Amplifier does not have a U-bridge what to do?

A low-impedance amplifier like a karaoke amplifier without a U-bridge will be a weakness, as the Equalizer and amp will not be connected effectively, thereby not providing an optimal audio experience.

You can buy a U-shaped bridge for from 10,000 VND to 20,000 VND at professional electronics stores, audio equipment repair centers, home electrical stores or homemade with copper wire. However, making a U-shaped bridge yourself is not safe and can cause electric shock or even fire.

Above is the concept of the U-bridge on the amp as well as its position and effect in the amp. Don’t forget to leave a comment if you have any questions that need to be answered!
