EAS-24-NODE-4D

Input and distribution module with DSP for EAS-24 amplifiers

One group of four 24-volt bus outputs for mono or stereo setups, one local stereo unbalanced output (RCA). Each output powers up to three EAS-24-AMP-30Ds. The module requires an external 24-volt power supply.

Distribution module with four outputs divided into two groups. Each group has volume control of the line audio input signals. As many as eight EAS-24-NODE-4Ds can be looped/connected on distances of several hundred meters.

  • It has two audio inputs: EAS and 100V input. The EAS input provides a balanced audio signal, and can also be used for connecing other EAS products. The 100V input is used to connect the node to an existing 100V system.
  • The EAS-24-NODE-4D contains an integrated audio DSP with 10-band parametric EQ, variable high/low-pass filter, dynamic processor with noise gate and loudness.
  • On customer request, Laud Media can modify the amplifier characterics in order to adapt to and significantly improve the performance of the selected speaker.
