A unique talkback system designed for TV presenters & production gallery staff, using AoIP AES67

7th September 2017

8 different sets of 4 channel mixers that can be assigned to presenter remote controls - an amazing control system using AES67 AoIP

The system consists of three parts: a Mix Engine, which forms the central core of this powerful presenter talkback system allowing up to 32 Presenter Remote Control units to control the mix outputs of 1 of 8 virtual mixers (VMs), each mixer having 4 mono channels. Technician Remote Control units can oversee all VMs, adjusting the level of the 4 mono outputs of each VM as an aid to presenters.

The Mix Engine houses the hardware where the complex routing, mixing and DSP functions are performed. This resilient 2U rack has dual hot-swappable AC power supplies and both 1Gb Ethernet & SFP ports.

The Presenter Remote controls the 4 channels of a virtual mixer, using four rotary encoder volume controls which give visual feedback for mix level of the source and actual input level. Multiple units can simultaneously control any of the 8 virtual mixers in the main mix engine with a display on the front panel of the virtual mixer being controlled.

The Technician Remote allows selection of each of 8 VMs and remote adjustment of volume controls.
