Switching-off the Termination of the Word Clock Input

CAUTION! Disconnect the unit from the mains before opening!

Remount the aluminium cover thoroughly before you attempt to operate

the unit!

When the MC-3+ Smart Clock is shipped, the BNC-based Word Clock input

connector is terminated internally with 75 Ω. Therefore, one jumper is put

on two pins - Position 2 - of the 3-pin socket JP1.

When moving the jumper from position 2 to position 1, the input termi-

nation will be switched-off. Therefore, the MC-3+ must be connected in a

chain, in which a device with terminated input follows. Otherwise you need

to use a BNC-T piece in combination with a 75 Ω BNC resistor for terminat-

ing the MC-3+’s input.
