Description

Studio Codec for Managing 6 Simultaneous Remotes

Rapidly expand your remote capability with the award winning Merlin PLUS and manage up to 6 bidirectional mono connections with IP codecs or smartphones using Report-IT, saving money on codec hardware costs and reducing studio rack space requirements.

Overview

Merlin PLUS is the ideal 1RU codec for studio installations and offers a simple, compact and scalable solution for managing multiple simultaneous remotes. Use Merlin PLUS for:

  • Up to 6 simultaneous bidirectional mono remote connections.

--------- Merlin PLUS 6 simultaneous remotes Report-IT Vertical sliders

  • 2 x Bidirectional mono or stereo remotes, each with separate bidirectional IFB communications channel.

--------- Merlin PLUS 2 x stereo plus IFB

  • Streaming multiple algorithms simultaneously at different sample rates and bit-rates over a range of connection transports.
