Installation and Operating Guide pro.Bose.com Fault Notification Output Each PowerMatch amplifier features a hardware fault notification circuit. This circuit drives a normally open or normally closed contact closure (1A, 30 VDC maximum). The fault output, using the orange-colored 3-pin terminal block (Phoenix Contact® #1976010, supplied), is intended to provide an external connection to a remote system monitor for fault notification purposes.
Installation and Operating Guide pro.Bose.com Setup and Configuration Figure 8 shows the basic signal flow and available DSP functions available to manipulate each individual input channel. Some functions and advanced parameters can only be modified using ControlSpace® Designer™ software. See “Interface Comparison Table” on page 40 to view configurations required to access functions and features. Figure 8.
