Pre-Installation
Please read all material carefully prior to installation. If you need additional assistance, contact your Lyngdorf
Audio representative.
Unpacking the Product
Carefully remove the unit and accessory kit from the carton and check for shipping damage. Contact the
shipper and your Lyngdorf Audio representative immediately if the unit bears any sign of damage.
Warning:
Never rest the TDAI-3400 on the front, as the volume wheel cannot handle the weight!
Keep the shipping carton and all packing material for future use. If this unit is shipped
without the original packing, damage could occur and void the warranty.
Inventory
Check the list below to ensure that all necessary product components have been delivered. Report all
discrepancies to your Lyngdorf Audio representative immediately.
•Owner’s manual
•Power cord
•Remote
•Microphone
•Microphone stand
•Microphone cable
•Microphone adaptor (XLR to mini-jack)
Operating Voltage
Lyngdorf Audio products must be connected to the mains power. The TDAI-3400 will not automatically detect
the voltage, so check and set the operating voltage on the switch next to the mains plug.
Ventilation Requirements
The TDAI-3400 does not have a built-in fan, nor does it require special measures to ensure proper heat
dissipation. It should be placed according to these guidelines:
•It should always have at least one inch / 25mm of free space on all sides.
•It should be placed in an environment free of excessive heat.

10
Home Automation System Integration
The TDAI-3400 is compatible with home automation systems via the RS232 and network connector on the
rear socket panel. The TDAI-3400’s trigger connections can also be programmed for use in a home
automation system.
IP Control
Connect the TDAI-3400 to your local network. Pressing the OK button on the remote and toggling through
settings, the TDAI-3400 will display the IP address allocated to the TDAI-3400.
Open a TCP connection on port 84 and use the same protocol as on the serial interface. Use Telnet, Putty,
or a similar program to open the TCP connection.
Preparing the TDAI-3400 for Mounting in a Rack
The TDAI-3400 processor is equipped from the factory with feet for free-standing placement, but a
rackmount is available as optional accessories. (Accessory item number 900008101)
