Setting up a HYBRID INTERFACE:
Connect the hybrid to one of the line inputs in this case we will use input channel 15 left. In most
cases a telephone hybrid is mono so connect its output to the left input and set the ‘config:’ to mono L
For this example we are using AUX6 as return to the hybrid so connect the AUX6 output to the input
of the hybrid with both L and R connected.
In this example we will be using GPI 14 for “ring detect” and GPO 15 for “hybrid ON” .
Connect the hybrid accordingly.
Briefly pushing the grey channel 15 “select” button that opens the channel settings window in the
display.
Push the blue “config” button on the touch screen that will open the settings window:
Select the input being LINE A, and briefly touch the “Type” box, the background will turn yellow, with
the rotary select “hybrid” and push the rotary button to confirm the selection.
Briefly push the “TB-output” box and with the rotary select “AUX6” being your return or Cleanfeed.
Confirm the selection by pushing the rotary. This also activates the green TB button above the fader.
Select the “MAIN A” and or the “MAIN B” box depending on the destination of the signal.
EXIT this screen and go to the channel AUX settings and make sure the level of AUX 6 is completely
turned down to mute. (one level up)
Of all inputs in all other channels that are part of or will be part of the return signal open AUX6 to the
desired level, in most cases nominal level.
Please note all AUX levels depend on and are stored with the selected INPUT so if you switch inputs
on a channel you have to adjust that level also!
Repeat the settings for the TBP output channel if appropriate.
Setup your Talkback microphone in the SYSTEMS menu ‘TB input ch:’ as described earlier.
GPIO
Standard for an Eela Audio hybrid the shape and type of the GPIO’s are continuous so do not select
any checkboxes in the main GPIO settings menu
An incoming call is indicated by a flashing LED in the grey 'SELECT' button. An off-hook or ON state is
indicated by a slowly flashing LED. The telephone icon in the main screen indicates an of-hook state
of one of the hybrids connected.
