Mic Gain Adjustment

Ajuster le gain du micro

En conformité avec la norme JTSO C58a, la tension de sortie du microphone est calibrée en usine à 400 mV. Si le niveau d’entrée micro de votre système d’intercom est plus élévée ou plus faible, la tension de sortie micro peut être réajustée sur celui-ci. Pour ce

faire, utilisez un petit tournevis et tournez la vis ‘Mic Gain Adjustment’ (voir l’illustration à gauche) jusqu’à la valeur de réglage désirée.
