1: Input connector
WBT Nextgen RCA connector. Please be careful not to twist the cable while inserting the RCA plug.
2: Termination
Switches are activated by setting down towards the „on“ position. Terminations are added in parallel to 47
kOhms /47 pF. This means that capacitance increases, resistance decreases.
Switches:
1 Cap. 1000 pF
2 Cap. 220 pF
3 Cap. 100 pF
4 Res. 100 Ohms

3. Gain
MM/MC Switch: down = MM (37dB)
up = MC (56dB)
Lo/Hi Switch: down = /
up = +10dB
The gain switches allow easy adjustment of even very low output cartridges.
4. Output connectors
RIAA filtered Line level outputs. Please connect to your preamplifiers line level inputs. Please take care for
correct connection of left and right channels.
WBT Nextgen RCA connectors. Please be careful not to twist the cable while inserting the RCA plug to
