Using A Microphone
You can use a PC or headset type electret condenser microphone with this product to control the jaw move-
ment.
To use a mic:
Make sure no audio cables are plugged into the Line In jack.
Power up the board as you normally would.
Move the red shorting jumper on “MIC J” (P1) so that it shorts (is over) both pins of the “MIC J” header.
Plug your microphone into the “MIC” (J1) jack and begin to speak.
You may need to adjust the “MIC Adj” (R1) pot to increase or decrease the microphones sensitivity. You
may also need to adjust the “VOL” and “LVL” pots to get the board to react in the desired manner.
NOTE: Please remember to remove the shorting jumper from the “MIC J” position if you decide to go back to
using the Audio In jack.
