In case you use the unbalanced input, put the resistor to the pinhead connectors “LOAD_RA” and “LOAD_LA” on the printed circuit board of the Grail preamplifier. Don't forget to connect resistors for both channels (Resistor on “Load_RA” and “Load_LA”). ________________________________________________________________________________ ® van den Hul Phonograph Preamplifier „The Grail SX“... - Page 9 50pF input capacitance. So you only have to add the missing part of the recommended total capacitance, given by the cartridge manufacturer. ____________________________________________________________________________ The heart of “The Grail”: the “Coils-Only” deemphasis network ________________________________________________________________________________ ® van den Hul Phonograph Preamplifier „The Grail SX“...

Page 10: Level Matching
Basically: the higher the “dB” figure, the higher the amplification factor and as a result the louder the music signals will be. In general: always set switches equal on both channels ________________________________________________________________________________ ® van den Hul Phonograph Preamplifier „The Grail SX“... - Page 11 Delivery condition for gain is 60dB (MC) and 40dB (MM), that means DIP switch slider 1 in position “ON” and slider 2 in position “OFF”. ________________________________________________________________________________ ® van den Hul Phonograph Preamplifier „The Grail SX“...
