In certain commercial applications a microphone paging override is required. Model MR171 paging and override module takes a balanced or unbalanced mic, (with defeatable phantom power) or a line level input and when activated overrides all inputs (even if some or all zones are in standby) and pages at a preset volume in all zones.
A variety of door chime and telephone paging, door entry and front door camera modules are being developed. Check our web site for more information.
The MVP44a includes a 12VDC trigger output to control and power various items when the MVP44a is powered up. When the MVP44a agoes into standby the trigger output ends. It's maximum output is 60mA.
An innovative IR connection system is also included to turn on and off the various source components as well as four separate commands. A Xantech
The on command is automatically generated when the MVP44a goes out of standby and into power up. The off command is automatically generated when the MVP44a goes from power on to standby. These sequences are generally used to turn on and off the source equipment.
To activate the four commands, when the system is powered up, press the MR60 keypad button FNC then quickly press one of the four source buttons on the top of the MR60 keypad. This will initiate a pulse at the MVP44a FUNCTION output, that in turn generates an IR command that is pumped back into the MVP44a IR emitter port 1 and out to the various emitters connected to ports
