Which amplifier is best for home use? (Part 2) Aug 09 , 2022

What factors should be considered when buying a home theater AV amplifier?

(Appearance and Function)

Remove all the packaging, and finally see the host. The intuitive feeling is that the material is heavy, the front panel is a very thick metal plate, the surface is brushed, and there are three rows of cooling holes on the top, but it does not reduce the strength of the fuselage much, and it feels solid and stable.

The overall feeling is that it has more of a professional power amplifier taste than a home machine, but it is more refined than a professional power amplifier.

There are two huge knobs on the front panel, which look dazzling silver, but it is made of aluminum alloy + plating, and it feels bad to use, and it does not have a good sense of heaviness and damping. The left is the K-song microphone volume adjustment knob, the right is used to adjust the music volume, and in theater mode, it manages the total volume.

In addition, this button can also be pressed in and used as a menu button and an OK button. In the absence of a remote control, with the following row of buttons, various functional operations can be realized on the machine.

Below the volume knob is a USB interface, which can be used to plug in a U disk or a mobile hard disk to listen to music.

The position of the bottom heat sink is a large heat dissipation hole, and the heat dissipation requirement of high-power amplification is relatively high.

Four foot pads with shock-absorbing foam, very strong and stable.

Looking at the back of the amplifier, the functional division is also very clear, which is much simpler than the dense interface of Japanese power amplifiers. The upper left is the front output interface of the RCA lotus head. For example, if you have a multi-channel power amplifier, you can connect it to achieve 11-channel 7.1.4 atmos sound effect.

Next is the XLR signal input interface, and to the right there are coaxial and optical digital signal inputs, which can be used according to the front-end equipment. Of course, the input and output of the HDMI interface are basically solved in the cinema, and these analog interfaces can only be used for listening to music.

The middle row is the HDMI input and output interface, 6 inputs and 2 outputs. Blu-ray players, set-top boxes, game consoles, etc. can be connected in any way, and the two outputs can be connected to TVs and projectors respectively, which can be said to be tailor-made for living room use.Below is a row of speaker binding posts, corresponding to 7 channels. Please keep in mind that our binding posts are designed symmetrically, unlike those of Japanese brands that are arranged L,R,C,LS,RS...from left to right.
