On our Option 11, we have a Macintosh Computer running iTunes that we are using the line out connected to our MOH port on our Universal Trunk Card.
Listening to the source through headphones the music is brilliant but
on hold" the music cuts in and out and is distorted. I looked at the connection and saw that it was connected strangely. The output of the Mac is stereo. Someone connected the left channel to "tip" and combined the right channel and ground to "ground" to combine left and right to a mono signal.
When I first heard the "On Hold Music" I thought it was an impedance problem. I changed the connection to a stereo connector combining left and right channels to "tip" and ground to "ground". I then ran the signal through a Bogen WMT1A matching transformer connected it's 600 ohm connection to the trunk port.
It helped a bit but mainly just reduced the volume of the distorted signal. Yest I adjusted the source volume to no avail. Is it possible that we have a damaged port?
This is the TNB printout. What else can I look at and is there a feature number I can dial to listen to the MOH port?
Thanks guys,
