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 PEQ/XO Chain; Positions 4–7). 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 1242, these relays switch power to selected
components. Not on the 1240.
E. Low-Level Bus Connectors – These connectors route signals from Module to Module
within a Chain and from Chain to Chain to form the signal bus.
F. Low-Level Connectors – Provides connection points for component inputs and outputs.
G. Component Turn-On Strip – Distributes 12 V DC power to components when they are
selected. Not on 1240.
H. LED Turn-On Strip – LEDs can be mounted near components to indicate when
components are activated. When a position is selected, the Turn-On Strip provides power to
the corresponding LED.
I. Input/Output Designation – Provides a space for labeling the module with relevant
information for each set of component connection points.
J. Module/Chain Name/Number – Provides a space for labeling the module with its chain
name and designation (e.g., PEQ 2, for the second module in the Passive Equalizer Chain).
K. Hi/Lo Jumper – Jumper set on Lo designates the module positions as one through four
(zero through three if bypass is required). Jumper set on Hi designates the module
positions as five through eight (four through seven if bypass is required).
