Channel D has proposed a revision of the premium Seta l Phono corrector. The device has been manufactured for more than 10 years — it is based on a fully differential circuit of a class a ultra-wideband amplifier with battery power.
As it turned out, the later version of Seta L, released after 2015, provides for operation in the TRANS-impedance mode (voltage — current conversion option-current mode). This mode is enabled by several jumpers on the device’s printed circuit Board.
Regarding owners of Seta L released before April 2015, Channel D reported that in their case, the upgrade “may entail additional components — and this issue needs to be resolved on an individual basis”.
The proposed upgrade makes sense for the Seta L to work with MS cartridges equipped with a low-resistance coil. As stated, it is in such a bundle that the TRANS-impedance scheme has significant advantages.
Upgrading the Seta L to work in the TRANS-impedance mode for owners of the Phono corrector from the United States will cost about $ 1,000, not including delivery. The manufacturer assured that the work will take a maximum of three days.
