RIAA curves
You can modify the RIAA curve by moving the jumpers located on the VPS main
board. The VPS complies with the 1953 and 1976 RIAA curves.
By default, the S4 and S5 jumpers
are in place and you can enjoy the
benefit of extended low frequency
bandwidth.
If your turntable generates noise
in the lower frequencies, you can
attenuate them by removing the
S4 and S5 jumpers. This position
matches the 1976 RIAA - IEC
curve, suited to “light” record
decks, whose platters generate
more noise.
