1PHANTOM +48V Switch/Indicator
This switch toggles phantom power on and off. If you set the switch on (
), the AUDIOGRAM supplies phantom power to the MIC/INST jack
•Be sure to leave this switch off
(
) if you do not need phantom
CAUTION power.
•When turning the switch on, be sure that only a condenser micro- phone is connected to the MIC/ INST input jack. Other devices may be damaged if connected to phantom power. This precaution does not apply to balanced dynamic microphones or instru- ments with the phone jack, how- ever, as these will not be affected by phantom power.
•To prevent damage to speakers, be sure to turn off audio system (monitor speakers) before turn- ing this switch on or off. We also recommend that you set the OUT LEVEL control to the minimum position. Neglect of these pre- cautions may result in large noise bursts that may damage your equipment, your ears, or both.
2MIC/INST Switch
Set this switch according to the type of device connected. Select MIC (
) if a microphone is connected, or INST (
) if an electric guitar or bass is connected.
NOTE If a device is not connected to the MIC/INST jack, set this switch to MIC (
). Otherwise noise may occur.
