FreeMate Headset model dh-011T

[Belinda Frick]

The wiring for the model dh-011T is as follows:

The red is speaker + .
The green is speaker - .
The yellow is mic + ,
and the black is mic - .

Inner pair is speaker.
Outer pair is mic.

The mic is polarity sensitive.

With the USB Taps we use the inner pair(speaker)
and outer pair(mic) standard. If you have recording
issues where the one side is soft, switch the outer
pair (mic) for polarity issues (positive and negative).

There is a 475 amplifier option - at extra cost.

The suggested headset for Call Centres is the model DH017.
