Phoenix Audio Duet Executive MT202-EXE - Manual (Page 7)

The Duet Executive is the only Duet model that can be Daisy Chained. Any number of
units can be connected in a Daisy Chain as long as all the units are Executive models.
This feature allows the Duet to cover medium to large conference rooms. Every unit in
the chain will utilize both its microphone and speaker.
DAISY CHAINING ExECUTIVES REqUIRES TwO ELEMENTS:
RJ11 to 2.5mm cable, like the one supplied with each Duet and used for a cellular
phone connection
3.5mm plug (we call it a Dummy Plug). The 3.5mm stereo plug is the standard
plug used by most powered speakers and headphones. Feel free to use your
household headphones
HOw TO DAISY CHAIN MULTIPLE UNITS:
Connect Duet #1 to your communication link (PC, telephone, or both)
Take the RJ11 to 2.5mm cable and plug the 2.5mm end of the cable into Duet #1
and the RJ11 into Duet #2
Plug the Dummy Plug into Duet #1’s 3.5mm jack
Setup output gain through the Phoenix Audio Technologies Setup Utility (0dB gain)
Power Duet #2 using the supplied power adapter (you can also power it from a
USB port)
NOTE: Plugging in the Dummy Plug signals to the Duet that it is in a Daisy Chain mode
and activates all the required algorithms. Failing to do so will disable the echo cancelling
algorithm and other critical functions.
NOTE: Phoenix offers a Daisy Chain Kit (MT221). This kit consists of an 11 foot RJ11 to
2.5mm cable and a Dummy Plug that can assist you with Daisy Chaining.
