IMPORTANT: The formula to find the correct value is as follows: DO NOT CHANGE Desired load impedance: Rload IMPEDANCE WHEN PREAMP IS IN PHONO Rload x 23500 PLAYBACK 47000 - Rload The result of this calculation equals the value of each of the resistors that is to be inserted in the sockets ( 1 pair per side ) We recommend the use of 1% low inductance metal-film resistors nut any resistor of preference can be used. - Page 16 WIRING SCHEMATIC EXAMPLE: LEFT CHANNEL NEGATIVE SHIELD POSITIVE VERY IMPORTANT: THE SHIELD OF THE CABLE MUST BE SHIELD INSULATED FROM THE OUTER PART OF THE LEMO CONNECTOR.
