To adjust the volume of Bakun Products' amplifiers, in addition to the current standard volume, a metal film resistor is set as an option.Attenuatorand non-inductive winding resistance attenuators, but from this April, it has been changed from a non-inductive winding resistance attenuator to a digital attenuator.
The digital attenuator is a newly developed attenuator by Bakun Products. It has higher accuracy than non-inductive wirewound resistance attenuators and can adjust the signal level more accurately. Therefore, the conventional switch typeThe attenuator had 2dB steps, while the digital attenuator has 0.5dB steps.
Digital attenuatoris a variation of the resistance ratio, just like a normal volume, and for SATRI amplifiers, the resistance value is varied. The error is within 0.1 dB in actual measurement. The digital board and the analog board are separate. Since it is a method of changing the resistance with a relay, there is no distortion. In addition, the wiring is shortened as much as possible by using a microscopic chip resistor, and the pattern width is as wide as possible.AttenuatorThere is little reactance and there is no incidental sound. The impedance of the board is reduced as much as possible in the ground plane, so it operates stably up to high frequencies.
Digital attenuators have high accuracy and controllability, as well as low noise levels, so that they can be used in conventionalCompared to the non-inductive winding resistance, there is a level of sharpness that I have never heard before, and there is no incidental sound at all.The resolution has also been improved. Digital attenuators also provide excellent signal stability and repeatability due to their high repeatability and low error and drift.
From non-inductive winding resistance attenuatorAs we move to digital attenuators, there will be some slight price changes depending on the model.
