DMTH4

Example Teleconferencing Setup

Link Conference Rooms with a DMTH4 Example Setup

The following information describes setting up a DMTH4 to connect two locations for a conference. The DMTH4 is designed to be part of a DM Series chain. In this example, the DMTH4 is a slave unit to a DM1624 Series Automixer. This example also as- sumes that the hardware has been installed and is operating properly. Conceptually, the setup has two conference rooms, each with two microphones and two ceiling mounted speakers connected to a DM1624 in a Mix-Minus configuration with a DMTH4 linking the

rooms together via a telephone connection. (See Link Conference Rooms with a DMTH4, Example Setup.)

The actual process to create the signal path so all members of both conference rooms have the ability to hear and be heard all other members in the conference rooms requires four simple steps: setting up the DMTH4 Main Matrix, setting up the DM1624 Main Matrix, setting up the DM1624 Expansion Matrix and setting up the DMTH4 Output Source Multiplexer. This is illustrated in Conference Room Signal Flow Dia- gram.
