Phantom Power
Each of the VS-2400CD’s eight XLR jacks can supply +48 V phantom power to a
connected condenser microphone that doesn’t have its own internal power source.
To Turn an XLR Input Jack’s Phantom Power On or Off
1. Hold down SHIFT and press EZ ROUTING•PHANTOM—the PATCH BAY screen
appears.
2. Press
or
to select the desired input jack if it isn’t already selected.
3. Turn the Time/Value dial to turn the jack’s phantom power on or off, as desired.
Setting Analog Input Levels
Once you’ve connected a signal to an analog input jack, you’ll need to set its level.
To Set an Analog Input Level
1. If you’re connecting an electric guitar or bass to the GUITAR HI-Z jack, be sure to
lock in the GUITAR HI-Z ON switch (Page 34).
2. Press HOME•DISPLAY on the VS-2400CD.
3. Send some signal into the input jack.
The eight input peak indicators (Page 122)—the
first 1-8 set of numbers in the top right part of the
screen—represent the eight analog input jacks.
4. Turn up the jack’s SENS knob until its peak
indicator lights on the display.
5. Turn the SENS knob counter-clockwise slightly until the indicator doesn’t flash.
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)
If you’ve already routed the input jack to an input channel, bring the input channel’s
fader all the way down before turning the jack’s phantom power on or off.
Read the manual for your microphone, and turn on phantom power only if you’re using
a condenser microphone that requires it. Phantom power can damage other mics.
To avoid damage to a connected mic or instrument, make sure the corresponding XLR
jack’s phantom power is turned off when you’re using one of the 1/4” TRS jacks.
You can view a jack’s level in the Home screen’s INPUT meter view only if it’s been
routed to an input channel. If you don’t see the jack’s signal, see Page 130.
You can set the level at which the input peak indicators turn on (Page 356).
