4 - Recording Using phantom power When stopped (and the INPUT1/2 or INPUT3/4 item is set to XLR/TRS on the BASIC screen for the channel being set), if you set the INPUT GAIN item on the INPUT screen to MIC+PHANTOM, a pop-up message appears confirming that you want to turn phantom power on. When the confirmation pop-up message opens, press the DATA dial to turn phantom power (24V or 48V) on for the 1/L, 2/R, 3/L and 4/R connectors and supply it to the connected mics. Use the MIC SETTING screen to set the voltage to 24V or 48V. (See "Setting the phantom power voltage" on page 21.) NOTE Battery power will be consumed faster when set to 48V than when set to 24V. CAUTION • Confirm that phantom power is OFF before connecting a line level device to the 1/L, 2/R, 3/L or 4/R connector. If you connect a line level device while phantom power is being supplied, that device and this unit could be damaged. • Before connecting a condenser mic to or disconnecting one from the 1/L, 2/R, 3/L or 4/R connector, confirm that the phantom power for that jack is OFF. If you connect or disconnect a mic while phantom power is being supplied, that mic and this unit could be damaged. • Turn phantom power ON only when using a condenser microphone that requires phantom power. • Supplying phantom power to some ribbon mics will break them. If you are unsure, do not supply phantom power to a ribbon mic. • When using USB bus power, the unit might not be able to supply phantom power depending on the computer. In this case, use a TASCAM PS-P515U AC adapter (sold separately). • Some condenser microphones will not operate when phantom power is set to 24V. • Do not connect or disconnect the power cable connected to the USB port when using phantom power. Doing so could interrupt the power to the unit even if it has batteries, resulting in the damage or loss of recording data. Setting the phantom power voltage Use the PHANTOM VOLT item on the MIC SETTING screen to set the power voltage supplied when a microphone that requires phantom power is connected. 1. Press the MENU button to open the MENU screen. 2. Turn the DATA dial to select MIC, and press the DATA dial. The MIC SETTING screen opens. 3. Turn the DATA dial to select PHANTOM VOLT, and press the DATA dial. 4. Turn the DATA dial to set the voltage of phantom power when it is supplied. Options: 24V, 48V (default) NOTE Battery power will be consumed faster when set to 48V than when set to 24V. 5. When finished, press the 1/8 button to return to the Home Screen. TASCAM DR-70D 21
