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 assumes 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 con-
figuration 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, set-
ting up the DM1624 Expansion Matrix and setting up
the DMTH4 Output Source Multiplexer. This is illustrat-
ed in Conference Room Signal Flow Diagram.
