Why do I need this?
Condenser micprophones are built with internal active electronic elements. To operate these mics the so-called phantom
power is necessary. It’s called „phantom“ because the low power is invisible to dynamic microphones. Condenser mics will not work if they
don’t get the necessary power of usually 48V over a balanced mic cable, in most cases a XLR cable. In this case the supply voltage is referenced
to the ground pin of the connector, pin 1 of the XLR connector.
Tip:
Some semi-professional condenser mics provide internal battery powering and don’t need the 48V power from the Nanoface. If you ask
yourself if your microphone needs phantom power or not, please have a look on the documentation or consult the manufacturer.
Press the encoder until the input LED (“In”) shines.
If LED 3/4 also shines, press the encoder 3 times until only the “In” LED is on.
The encoder controls now the gain for both XLR inputs on the breakout cable.
After a 1-click turn, the 1st LED of the left or right channel blinks one time to show, which channel is
selected. To switch back to gain control of channel 1+2 together, press and hold the encoder and turn
it to the right from channel 1 and to the left from channel 2.
Make sure the input signal is not clipping (red top LEDs turn on).

Why do I need this?
Microphone signals are low level signals and need to be amplified. The two Nanoface preamps
on inputs 1 and 2 provide a gain amplification of 50.5 dB. More than enough for most microphones.
Tip:
To bypass the preamps of the Nanoface turn the encoder for one or both channels all the way down.
Tip:
To find the best gain, play or sing the loudest reference tone in your performance and raise the gain until it clips.
Now lower it to a safe value.
1. Switch to input 1/2 mode
.
2. Press and hold the encoder. Turn it to the left for channel 1 or turn it to the right for channel 2.
Press the encoder until the input LED (“In”) shines.
If LED 3/4 also shines, press the encoder 3 times until only the “In” LED is on. The
encoder controls now the gain for both XLR inputs on the breakout cable.
After a 1-click turn, the 1st LED of the left or right channel blinks one time to show, which channel is
selected. To switch back to the control of channel 1+2 together, press and hold the encoder and turn
it to the right from channel 1 and to the left from channel 2.
The 1st red LED of the left chain (= input 1) turns on. If channel 2 is selected, the 1st LED in the right
chain turns on.
To avoid the accidently activation of the phantom power, it’s not possible to activate/deactivate
the phantom power at the same time for both channels. It’s only possible by a previous selection of
input channel 1or 2. If you not press the encoder long enough, the Nanoface changes to input 3/4.
Turn phantom power (48V) on/off
1. Switch to input 1/2 mode
2. Press and hold the encoder. Turn it to the left for channel 1 or turn it to the right for channel 2.
3. Turn the encoder gradually to the right to raise the gain for the selected input(s).
3. Press the encoder for 3 seconds.
Turn the phantom power off: Select channel 1 or 2 and press the encoder for 3 seconds.
For an exact control of the available headroom to the clipping border please use the level meter
readouts in your audio software.
