Transformateur à 23 secondaires, possibilité de le câbler pour obtenir 6db. Bande passante 10-35kHz (-1 dB). Atténuation -63dB b'"'The benefit of replacing plastic type volume control to stepped attenuator is obvious! However, the accuracy of tracking and the quality of selector switch plus low noise resistors can reduce the signal loss to some degrees. Moreover the regular stepped attenuator featuring resistor type fails to offer impedance matching over plastic volume control. That's why at high attenuation level (low signal out, low listening level) the bandwidth of such volume control is very poor and the bandwidth is not constant over any switch positionb'"' Description, mesures sur le site de Sac Thailand (Silk), ici: https://www.sacthailand.com/Transformer_Attenuator.html Prix neuf: 370€ + 30% frais d'importation + port: env. 500€ Switch Elma 24 positions, contact or: b'"'High-quality selector switch, non-magnetic bodied switch with 3-micron gold plated contacts over copper alloy.
