Currently, new power amplifiers are being developed in Bachoon Products.
It is almost complete, butAMP-5521
The following is an excerpt from Facebook in Bacoon. I'm looking forward to it.
10% distortion rate up to 4Ω load: 54W
10% strain rate up to 8 Ω load: 35W
1% strain rate up to 4Ω load: 44.3W
1% distortion rate up to 8 Ω load: 28W
Frequency characteristics (8 Ω1W): 20Hz: 0 dB, 20 kHz: 0 dB, 50 kHz: -0.6 dB, 100 kHz: -6.29 dB
8 Ω 10 W: 20 Hz: 0 dB, 20 kHz: 0db, 50 kHz: -0.7 dB, 100 kHz: -6.4 dB
S / N ratio: VRMAX: -100 dB, VRMIN: -127DB
Output vs. distortion rate (1 kHz)
Output (W) 4Ω 8Ω
0.1 0.1 0.047
0.2 0.14 0.061
0.5 0.22 0.1
1 0.32 0.15
2 0.47 0.23
5 0.76 0.38
10 0.82 0.57
20 0.91 0.68
28 1
30 0.95
35 10
40 1
50 7.4
54 10
The bandwidth also extends as a non-feedback amplifier, and I think it is distorted.
Since the noise decreases when the VR is lowered as a feature of the SATRI amplifier, S / N when the VR is lowered is improved by 27 dB.
In addition, it is also one of the features that the output is small by the output.
