Operating Elements and Connections
1 Power LED
2 Power switch
3 Inputs (XLR jacks, balanced) of channels 1 to 4:
connection of balanced capacitor microphones or
electret microphones designed for a 48 V phantom
power supply
4 Outputs (XLR chassis plugs, balanced) of chan-
nels 1 to 4: connection to balanced microphone
inputs on the audio unit (mixer or amplifier)
5 Mains fuse; replace a blown fuse by one of the
same type only
6 Mains cable to connect 230 V~/50 Hz

Applications
The phantom power supply unit EMA-400 supplies the
required voltage to capacitor microphones or electret
microphones designed for a phantom power of 48 V
.
Thus, it allows connection of these microphones to
mixers or amplifiers which do not provide any phantom
power. It is possible to connect up to four microphones
to the unit.

Important for U.K. Customers!
The wires in this mains lead are coloured in accord-
ance with the following code:
blue = neutral, brown = live
As the colours of the wires in the mains lead of this
appliance may not correspond with the coloured
markings identifying the terminals in your plug, pro-
ceed as follows:
1. The wire which is coloured blue must be con-
nected to the terminal in the plug which is marked
with the letter N or coloured black.
2. The wire which is coloured brown must be con-
nected to the terminal which is marked with the
letter L or coloured red.

Setting the Unit into Operation
Up to four capacitor microphones or electret micro-
phones can be connected to the phantom power supply
unit. The microphones must have a balanced connec-
tion.
1) Connect the cables of the microphones to the
“MICROPHONE INPUTS” (3) of channels 1 to 4.
(The XLR jacks are provided with a latching device.
To release it, press the PUSH lever of the corre-
sponding jack when disconnecting the plug.)
2) Connect the “OUTPUTS” (4) of channels 1 to 4 to
balanced microphone inputs of the audio unit used
(mixer or amplifier).
3) Connect the plug of the mains cable (6) to a mains
socket (230 V~/50 Hz).
4) Switch on the phantom power supply unit with the
switch “POWER” (2). With the unit switched on, the
power LED (1) next to the switch lights up. After op-
eration, switch off the unit with the “POWER” switch.
