DirectAddress QX-3d & QX-3f 
 
These models of the music mini-system are able to handle both wholehouse music and voice page. They require however a higher level Controller (Ultimatoll) in order to deliver voice page. Wholehouse voice page is realized with home handsets which output to the mini-speakers attached to the DirectAddress module. The higher lever Controller interfaces with the home phones and the DirectAddress module directly handles the speakers. The module and the Controller are attached to one another.

Note that most Ultimatoll Controllers can directly handle the speakers by themselves. However, if the system altogether includes exterior doorphone stations, all of the Controllers require the DirectAddress module in order to handle the indoors mini-speakers.
