[PHANTOM] switches
The VR-4HD supports phantom power. When using a condenser microphone that
requires phantom power, set the [PHANTOM] switch to “ON.”
NOTE
5 Always turn the phantom power off when connecting any device other than
condenser microphones that require phantom power. You risk causing damage if you
mistakenly supply phantom power to dynamic microphones, audio playback devices,
or other devices that don’t require such power. Be sure to check the specifications of
any microphone you intend to use by referring to the manual that came with it.
(This instrument’s phantom power: 48 V DC, 10 mA Max)
