PR 4092

9 INPUTS, 2 OUTPUTS PREAMPLIFIER

PR 4092

PR 4092 has been designed to provide a flexible solution for any paging and music application in PA systems.

Each of the 9 inputs can be sent to output A only, output B only, or both A+B; in this way PR 4092 can also be used as a doublepreamplifier: "A-bus" dedicated to paging, "B- bus" for BGM programs. Thanks to the "2 in 1" design, priority function relevant to the inputs is active on the ouput selected only, by not affecting the other output bus. Input 1 has overall priority (voice or contact activated) and can be used for emergency paging; Inputs 2 and 3 together can be set with priority on Inputs 4 to 9.
