Why do home theaters need power amplifiers? If you want to further improve the sound quality and sound field envelopment of your theater speakers, adding a power amplifier will give you immediate results. The general entry-level power amplifier is the front-level decoding + the rear-level power amplifier = the combined machine. The installation of the rear-level power amplifier is to separate the front-level function of the combined machine, and let the independent rear-level power amplifier be responsible for giving the speaker a greater wattage to play the speaker. performance.

The volume and sound field of the speaker will decrease with the distance from the sofa. The wattage of the integrated machine does not meet the wattage requirements of the speaker. The high-frequency and low-frequency of the speaker are not balanced. Generally, novice players can only hear the sound at best.

Add power amplifier

At this time, we install a post-stage power amplifier to increase the wattage to push the left and right channels. After obtaining a larger wattage, the high, medium and low frequency tri-band will be more balanced, the harsh sound will disappear, and the sound field will increase like a purple area. The width becomes larger, and sofa listeners will feel that the sense of envelopment of the sound field has improved significantly.

The post-stage improves the overall performance of the speaker: the high-frequency extension is more sufficient and the details are richer; the dynamic improvement of the intermediate frequency enhances the sense of movement of the sound; Or the vibration of the sofa will also increase.

If the player uses the integrated machine to push the 7-channel speaker, the sound field in the purple area is small, and there is only sound. The sound fields of the speakers cannot be connected. For example, when a bullet flies from the left to the right, the listener will only hear the sound of the left firing and the right hitting the steel plate. For beginners, the sound of the left and right is different, which is normal.

Add power amplifier

All the speakers in the theater will add a powerful amplification effect, and all the speakers will create a sound field enclosure around the listener. The tri-frequency extension adds a lot of details, so that the bullets fired from the left will feel the concurrency of the muzzle sparks and the thick guns. Recoil force, the bullet trajectory passes through the sofa area, through the sound field amplification of the front three speakers and the rear ring, you can feel the dynamic sense of the bullet moving density from left to right, and then the powerful impact force when the bullet hits the right steel plate!! Can be based on The caliber of the bullet is different, the sense of volume and even the body feeling when hitting the steel plate will have a powerful feeling, or the position of the shotgun muzzle is changed, and the shotgun is fired from the front muzzle towards the listener's face!! The shotgun erupts from the front~~ to the listening seat It feels like a shotgun hits your face!! This strong physical sensation is really addictive
