Appendix 1 - Jumpers on optional Internal RIAA Module

Low Pass Filter
As configured from the factory, the low pass "rumble" filter is set at the 10 Hz position. To disable the
filter (this is intended for test bench testing and is not recommended), move all four jumpers indicated
into the DC position.
Neumann RIAA Curve Modification
The Seta is configured from the factory for the standard RIAA curve. The Neumann modification
introduces an extra high frequency time constant to compensate for the putative roll-off of the mastering
lathe cutting head. The Neumann setting can be enabled by removing the two jumpers indicated (or
placing them in the "parking" position, with one pin open).
