Phoenix Audio Duet Executive MT202-EXE - Manual (Page 5)

USING THE DUET
The Duet’s control panel has 3 buttons:
• Mute (in the middle)
• Volume Up (to the right)
• Volume Down (to the left)
LIGHT INDICATIONS:
• Button panel light off - unit is off (not connected)
• Button panel light on – unit is on (connected)
• Button panel light blinking – unit is on and the microphone is muted
BASIC UNIT OPERATIONS:
Turn unit ON: unit is always on when connected to a power source or USB device.
Turn unit OFF: disconnect unit from power source or USB device.
Mute microphone: push the Mute button once. The button panel light will start blinking.
Unmute microphone: push the Mute button once. The button panel light will stop blinking and
will stay on.
NOTE: The MUTE button will mute the microphone not the speaker. To mute the speaker just
use the volume buttons to decrease the volume till no sound is audible. The volume buttons
will control the level of audio heard from the speaker and not the sensitivity of the Duet’s
microphone. To adjust the microphone volume level use the Phoenix Audio Setup Utility which
can be found on our website.
Output gain controls the level (sensitivity) of the Duet’s output audio signal going into your
telephone. If the gain is set too high, the telephone input will clip the signal and the Duet will
fail to cancel the “line echo”. As a result you may hear an echo returning when you speak. If
the gain is set too low, the other side may have trouble hearing you or won’t be able to hear you
at all. You can customize your output gain by downloading the Phoenix Audio Setup Utility:
