Phoenix Audio Technologies DUET VCA - Manual (Page 22)

Note: Some cellular phones are equipped with a stereo 3.5mm headset jack (3 band). In order to
use the Duet with these telephones you must purchase an adaptor with a 2 band 2.5mm female
jack and a stereo 3-band 3.5mm plug (four contacts).
Note: There are two cables with RJ11 connectors on both sides (one grey and one black). The
black cable works with some IP telephones, while the grey cable works with others. If you
connected one and do not hear a dial-tone please try the other one.
Chose the cable which is appropriate to your telephone, plug the RJ11 connector into the Duet and
the other side of the cable into your telephone.
When available, the Executive can be powered through the USB connection. If a Computer / USB
connection is not available, use the AC/DC converter that is supplied with the unit. The converter
plugs into the unit’s USB jack.
Finally, set the appropriate input gain level. To do this, please refer to the next section titled:
“Setting up a telephone’s output gain”.
