A. LED – Indicates that this Module is activated (active or bypassed).
B. DIP Switch – Using binary code, designates Component Selection Numbers for each
Switching Module (e.g. Module 2 in Speaker Chain, Positions 8–15). See Appendix A for
DIP Switch setting instructions.
C. Control Cable Connectors – Supplied Control Cables are connected to these to connect
the first Switching Module in a Chain to the MVP Control Panel, then connect Module to
Module within a Chain.
D. Component Turn-On Relays – On the 1412, these relays switch power to selected
components. Not present on the 1410.
E. High-Level Connectors – Provides connection points for component high-level inputs and
outputs.
F. Component Turn-On Strip – Provides connection point for 12V DC power to Module
and distributes power to components when they are selected. Not on 1410.
G. LED Turn-On Strip – For non-lighted components (e.g., Speakers), LEDs can be
mounted by the Speaker to indicate activation. When a Position is selected, a contact is
made and the Turn-On Strip provides power to the LEDs.
H. Input/Output Designation – Provides a space for labeling Module with correct
information for each set of component connection points (e.g., SPK IN for the inputs of
the Speaker Chain).
I. Speaker Coil Shorting Pins – When Module is used to switch Speakers, placing jumpers
on these pins prevents out-of-phase cone vibrations by shorting all non-selected Speaker
coils.
J. High Level Bus Connectors – connects Switching Module to Switching Module within a
Chain, and Chain to Chain to form a bus.
