24-Step Ladder-Type Attenuator - 10K Log – 2 Channel
Our stepped attenuator is made with thin film resistors 0.1% 25 ppm. A perfect companion for any high end audio device.
The most important feature of a two channel Attenuator, namely potentiometer, is how well it tracks: that is, how closely matched between the two channels and also the input impedance is kept unchanged for different volume. No volume control has perfect tracking: one channel will always have a little different from the other. Even well-trained ears are only sensitive enough to notice a difference of about 1dB, though, and for the average person the minimum noticeable difference is more like 3dB. Therefore, a step Attenuator is often employed in high-end audio products.
