Detailed Description ID48X
ID48X is an installation loudspeaker processor in the NST Audio DSP system range, with 4 analog inputs and 8 analog outputs. It combines AES3 digital I/O with onboard signal processing for routing, system management and loudspeaker applications.
Processing includes equalization, delay, gain and output limiting, with functions and filter resources specific to the model. Input-equipped models add input dynamics and filtering before signals are routed to the outputs. The technical table distinguishes physical I/O, network-audio channels and processing resources.
D-Net provides device setup, routing, monitoring and preset management over a suitable network. D48X and ID48X also support FIR filtering, within their published tap limits. The platform supports professional installations and live sound systems where repeatable routing and loudspeaker processing are required.
