                 How to see the technical data to choose the correct AV power amplifier?

If you want to buy an AV power amplifier, when you start looking for it, you may look at a bunch of unfamiliar audio technology data like a bible, and have no clue about the numerous terminals on the rear panel of the power amplifier. For someone who is not familiar with home audio equipment, reading this data and picking the right equipment can be a great challenge. However, with a little guidance, shopping for an AV receiver for home theater can be a simple process. The following summary hopes to help you choose the AV power amplifier that suits you.

Are there enough amplifier channels to provide an immersive experience?

Amplifier channels send the sound from the AV amplifier to your speakers, so channel count is one of the most important considerations. A basic surround sound system has at least six channels, which means you can use a basic 5.1 speaker configuration with a center speaker, left and right channel speakers, two surround speakers and a subwoofer.

More amplifier channels allow more speakers to be connected, resulting in more detailed and powerful sound reproduction, creating an immersive sound field throughout the viewing area. If your AV receiver supports higher 3D audio formats (such as Dolby Atmos or DTS X), you can achieve greater sonic detail and accuracy of soundstage positioning by including a two-layer surround speaker arrangement.

The main feature of the latest 3D surround sound format is the addition of heightened surround speaker groups. The basic configuration of a 3D sound field speaker system is composed of horizontal plane speaker groups (center channel, surround sound, left and right speakers), heightened channel speaker groups (surround sound, left and right speakers) and a subwoofer. Dolby Atmos can be accomplished with 5.1.2, 7.1.2, 5.1.4, 7.1.4 and 9.1.4 speaker arrangements.

If you want to enjoy movies and TV with 3D audio details, choose an AV amplifier that supports at least 5.1.2 settings. If you want to use more heightened surround channels or subwoofers in the future to achieve better and larger sound field restoration, then you must choose an AV amplifier with more power amplifier channels to support future upgrades and expansions of the home theater system.

Can you connect each component?

Since the AV receiver is the centerpiece of your home theater, it should have enough inputs and ports to support all of your playback devices, whether wired or wireless. For the best picture and sound quality, it is very important that the AV amplifier supports the connection of the latest HDMI input devices. The HDMI input with High-bandwidth Digital Content Protection (HDCP) supports 4K Ultra HD video and the latest audio codec formats. If these input devices are not supported, you may not be purchasing an AV amplifier that will deliver the best picture quality promised by your video equipment, or you may have set up an Atmos speaker configuration but will not be able to deliver Atmos sound. In other words, it will cost you a lot of time and money.

The more HDMI ports your AV amplifier can use, the better you can add playback devices to your home theater system in the future. Multiple Modes of Wireless Connectivity - In addition to enabling mobile and web audio playback, they'll come in handy if you plan to set up multi-room audio or stream music.

Does your AV amplifier have enough power?

The power rating of an AV amplifier is one of the most important performance indicators, but it can also mislead you because manufacturers may test power output differently. In general, delivering more power per amplifier channel results in a louder, clearer sound. This means you won't lose tiny details during moments when the soundstage gets particularly loud and complex.
