Description
Each Mixer provides a digitally controlled analog 8-Input automatic mixer with an optional ECA 1 Echo Canceller. The ECB 62 Base supports up to 6 ECM 82 Mixers allowing up to 48 mic or line level Inputs. The ECM 82 communicates with the ECB 62 via the Expansion Data connection. Unlike other automatic mic mixers, each Input is programmable as either a Last-On or Gated Output. Only Inputs placed in the Last-On mode may become the Master Channel. All operating parameters are stored in the Base’s nonvolatile Memory and uploaded to the Mixers on power-up. The ECM 82 comes with an ECS interface cable, security cover, and daisy-chain power supply cable.
