Phantom Power

Each of the S-4000S's inputs can supply +48 V phantom power to devices that require it, such as
condenser microphones or active direct boxes.
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, 14
mA Max.)
Use the following procedure to turn on phantom power on a particular
channel:
1. Select the desired channel (1-32) with the CHANNEL knob.
2. Press PHANTOM +48 V so its indicator lights.
3. Repeat Steps 1-2 to turn on other channels' phantom power.
To turn off a channel's phantom power, select the channel with the CHANNEL knob, and then press
PHANTOM +48 V so its indicator goes out.
While a channel's phantom power setting (on/off) is changed, its output is temporarily muted
to avoid noise.
