Example Teleconferencing 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.
