The DS3002 is designed to provide sound masking, paging and music functions for centralized and networked sound masking systems. Each DS3002 provides four independent sound masking generators, each having 1/3 octave band equalization, adjustable high pass and low pass filters. Additionally, two balanced line level inputs, two balanced line level outputs and a matrix mixer facilitate configuring any mix of incoming signals with any of the sound masking generators and then routed to any of the outputs. Input processing includes per channel level control, equalization and configurable softknee compression. Output processing includes per channel level control for both analog and network audio. This feature provides unique functionality for use in traditional 70v. centralized systems, networked addressable systems or systems combining both approaches.
