Installation Guide
The following are assumed:
•A POTS line has already been connected to the DMTH4 rear panel Telephone Line jack
•The DMTH4 has been connected to the DM1624 via the DANI bus
•The microphones and overhead speakers are already connected to the DM1624 in a
The result will be that when a person talks into Mic 1 in Conference Room 1, they will be heard both in Confer- ence Room 1 and in Conference Room 2. Likewise, if a person in Conference Room 2 talks into one of the microphones in that room, they will be heard both Conference Room 2 and Conference Room 1.
The following discusses setting up a DM Series consist- ing of a DM1624 Digital Automixer and a DMTH4 Digital Telephone Hybrid on near end of the telephone connec- tion. The same process is used to set up the DM Series at the other far end of the telephone connection.
Setting up the DMTH4 Main Matrix
The TEL Input needs to be configured so that it is connected to DANI Bus Mix Busses 1 and 2. (See Conference Room Signal Flow Diagram.)
1.) Select the Matrix Tab in the DMTH4 Control Panel, then select the “Main Matrix” sub tab. Right click the TEL input to Mix Bus 1 crosspoint and select “Enable Crosspoint” from the popup menu
2.) Repeat Step 1 for Mix Bus 2.

Setting up DMTH4 Main Matrix
Setting up the DM1624 Main Matrix
The DM1624 Main Matrix needs to be configured so the microphone inputs are connected to the output chan- nels used to drive the local sound reinforcement speakers. These inputs will be mixed together with the audio received from the DMTH4 TEL Input. Both local audio and audio from Conference Room 2 are heard on
the speakers in Conference Room 1. (See Conference Room Signal Flow Diagram.)
1.) Select the Matrix Tab on the DM1624 Control Panel, then select the “Inputs to Outputs” sub tab.
2.) Right click the Input Channel 1 to Output Channel 2 crosspoint and select “Enable Crosspoint” from the popup menu.

3.) Right click the Input Channel 2 to Output Channel 1 crosspoint and select “Enable Crosspoint” from the list.
Setting up the DM1624 Expansion Matrix
Once the DM1624 Main Matrix has been set up, the DM1624 Expansion Bus Matrix needs to be configured so the local audio is sent back to the DMTH4 for distribution to the remote Conference Room (Confer- ence Room 2 in this example). (See Link Conference Rooms with a DMTH4, Example Setup and Conference Room Signal Flow Diagram.)
1.) Select the Inputs to Expansion Outputs Tab in the DM1624 Matrix Tab.
2.) Right click the Input Channel 1 to Expansion Out Channel 1 crosspoint and select “Enable Crosspoint” from the popup menu.
3.) Right click the Input Channel 2 to Expansion Out Channel 1 crosspoint and select “Enable Crosspoint” from the popup menu.
