Page 7: Overview
The iPAM400 is designed to use the MX Series Amplifier Modules, and is not compatible with the M100, M200, and M400 M Series Amplifier Modules. These two series of amplifier modules are electrically identical, but have different mechanics and connectors.
Page 8 Each iPAM400 is a self-sufficient VIPA unit with local intelligence and can be configured to run as stand- alone unit or in a network. The iPAM400 supports full peer-to-peer IP communications for both voice and control.

Auxiliary Power Supply Output The iPAM400 provides an auxiliary supply output (21 V to 38 V) which can be used to supply other pieces of equipment up to a limit of 1 A. This supply output is derived from the mains and battery supplies. The auxiliary power supply output and the integrity of the auxiliary supply fuse are monitored and indicated via a front panel LED.
Page 17: Amplifier Modules
• MX400 400 W Amplifier Module The MX100, MX200, and MX400 amplifier modules respectively occupy one, two or four slots in the iPAM400 mainframe. A front fascia panel is fitted to the mainframe to provide protection for the amplifier module(s) and annotations for the LED indicators.
Page 18: Loudspeaker Line Monitoring Using Dc Surveillance
2) The iPAM400 temporarily superimposes a continuous surveillance tone on its outputs when requested by the amplifier motherboard. This happens during the fault diagnostic process. When the amplifier motherboard detects a fault, it requests the iPAM400 to superimpose a continuous surveillance tone on the required output for the duration of the diagnostic process in order to be able to isolate the faulty lines quickly.
