Jumper Selections
Impedance Selector
This module can be set for two different input impedances. When connecting to a 600-ohm source,
it is desirable to have a 600-ohm matching input impedance. For typical source equipment, use
1
0k-
ohm setting.
Input Muting
This module’s input can remain continuously active or be muted by other modules. When muting
is enabled, the input is permanently set to the lowest priority level. When disabled, the input will
not respond to any priority signal and will remain active continuously.
Input Bus Assignment
This module can be set to operate so that the input signal can be sent to the main unit’s A bus, B
bus, or both buses. Bus selection pertains to M-Class use only. Power Vector has only one bus. Set
jumpers to Both for Power Vector use.
External Mute Priority Level
Determines what priority level the system will see when looking at the external control. Selecting
Level
1
will result in the external device becoming the highest priority mute and silencing all lower
priority modules. Likewise for all other lower settings except for priority Level 4, which is not appli-
cable since modules with this level can only respond to mute signals. Priority Level 4 modules can-
not send mute signals.
