Z4 II & Z8 II Installation and User Manual v1.0 23
PCB jumper location and settings
The Z4 II and Z8 II have various internal jumpers, the setting of which may require alteration during installation. Note that there
are jumpers on both the motherboard and the individual zone sub-cards. The table below lists each jumper and its purpose,
together with the factory default setting. Note that options selectable by jumpers on the zone sub-board are per-zone, and
will need to be set on as many zone sub-boards as necessary.

The diagram below shows the locations of the internal jumpers (not to scale) on each of the board types. The jumpers have
two possible positions; the black square in the symbol indicates the default setting. If any jumpers need to be changed, turn
the Zone Mixer off and disconnect it from the mains. Undo the 6 screws securing the top cover of the unit and remove it.
Use a pair of small pliers to gently remove the jumpers from the PCB headers and reposition them. The jumpers on the zone
sub-boards are readily accessible from above; those on the motherboard will require long-nosed pliers. Refix the top cover
using the original screws.
fig. 27 and fig.28 give the locations of all the jumpers and of the socket for the optional Bose® EQ cards.
