The output is 35W + 35W stereo, and the mono BTL specification allows 100W output.
The most important feature is that the amplifier is fully equipped with surface mounting parts that do not have lead wires. The company's amplifier resistors, capacitors and semiconductors have used components with leads.
However, currently there are few products using lead parts, and the acquisition of lead parts has become tight.
The company was forced to choose whether to use expensive lead parts or to change the design of the amplifier itself and use surface mounting parts without leads.
The company chose to use surface mounting parts.
Not only that, but by using surface-mounted components with no lead wires, we decided to create a high-precision amplifier that could not be realized before.
If there is a lead wire, the sound will be colored due to its material and nature. By eliminating the lead wire, I thought that there would be no coloring. We reviewed the design method of printed circuit boards for mounting parts when using surface mounting parts. The length of the wiring of the print pattern that colors like the lead wire is 1/4 or less. In addition, we have developed many new circuits that can be highly accurate by using surface mounting parts.
Until now, the bias current needed about 4 minutes to stabilize, but AMP-5521 succeeded in making it less than 10 seconds.
The amplifier is 50 times more accurate than conventional lead wire parts. In combination with SATRI speakers, realistic playback like a player in front of you is now possible.
