SATRI's new amplifier

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.
