Edge series of digital audio processors
Up to 16 digital audio processors, capable of AEC, ANC, AFC, and AMX functions.
An automatic mixing matrix with 8 inputs and 8 outputs, equipped with 8 analog inputs and 8 analog outputs, 4 dante inputs and 4 dante outputs. The microphone input and line input can be freely switched, and each input comes with a 48V phantom phase power supply selection. Built in DSP functions such as feedback suppression, automatic mixing, matrix mixing, equalizer, distributor, compressor, etc. Connected to computer software through a network for control, or connected to the central control via RS232 for remote control, suitable for use in various public address projects. Applicable occasions: conference rooms, multifunctional halls, auditoriums, courtrooms, professional performances
