- What should be noticed when selecting and installing speakers?
A: The average output power of the backaudio A61, A66 host machine, and A82 extension is 50W, so two CR amplifiers or speakers with 4-8 ohm impedance and 20W power are enough. The output power of each sound channel is 25W, so it is suggested the power of the speaker be above 15W, taking the line loss into consideration. If the lower power amplifier is used, it is suggested the volume not be too large or the machine may be damaged. Consider the human activity features when installing speakers to secure the Hi-Fi stereo experience. For example, install the speakers on both sides of the sofa in the sitting room; on both sides of the bed in the bed room; on both sides of the desk in the study; on both sides of the dining table in the dining room.
The distance of the speakers should be 1.5 times of the storey height to secure the good Hi-Fi Stereo experience. If it is a large room, it is suggested to have two 8 ohm speakers connected respectively with the left channel and right channel to guarantee the balanced sound and better Hi-Fi Stereo experience.
