About 200 or so. As long as the down stream devices are all bridging, there
is very little loss of signal level from device to device beyond cable loss and
connectors. The problem though is in the looping path, one device needs to
come out, you break the whole signal path to what ever is downstream. If you
use a T connector, you will eventually get enough reflections from the open
stubs that the pulse will be too distorted with echoes. Good Engineering practice
is to use one output per device, and if necessary, loop the input to
additional DA's for more outputs. If it just sync, and you are on a tight budget, you
can build your own very cheaply from "radio shack" parts.
