Step 2. JP1 on the SV extension board is a 3-pin jumper
header and its short circuit socket is normally set to A
position. If you need to bypass the external attenuator
not only on all-zone broadcast but also individual
zone broadcast, set the socket to B position.
Note
External attenuator bypass function with individual
zone broadcast can be used only with 4-wire
attenuators.
This function basically cannot be used with
BGM/Paging function.
Step 5. Make connections of the supplied flat cables.
5-1 Remove the flat cable connected between the VM
CPU board's CN7 and the VM relay board's CN1001
of the VM amplifier.
5-2 Connect the supplied 2 flat cables to CN7 and to
CN1001, respectively.
