Steinberg UR28M Operation Manual page 8

• When turning phantom power ON, make sure that no
equipment other than phantom-powered devices
such as condenser microphones are connected.
Devices other than condenser microphones may be
damaged if connected to the phantom power supply.
Note, however, that the switch may be left on when
connecting to balanced dynamic microphones. When
connecting an unbalanced device to the MIC/LINE/HI-
Z 1/2 and phantom power is turned on, hum or noise
may result; this is not a malfunction or failure in the
device.
• Do not connect or disconnect a device while
phantom power is applied. Doing so can damage the
connected device and/or the unit itself.
• To protect your speaker system, leave the monitor
speakers turned off when switching the phantom
power on/off. It's also a good idea to turn all output
volume controls down to their minimum. Neglect of
these precautions may result in large noise bursts
that may damage your equipment, your ears, or both.
