Connecting the inputs
1. If phantom power is activated, turn it o.
The 1st red LED in the channel(s) to which the microphone will be connected
has to be tunred o (input 1 = left LED; input 2 = right LED).
Attention! Activated phantom power can damage other equipment (e. g. ribbon
mics). Phantom power should always be turned of if it’s not needed for a connected
condenser microphone. In contrary to condenser microphones (see next page),
dynamic microphones, like the Shure SM57 and SM58, don’t use internal electronic
components which needs to be fed by external phantom power. Before you connect
such a mic to analog input 1 or 2, make sure the phantom power is not active. The first
red LED in the channel to which the microphone is connected, has to be off.
Turn phantom power o: Switch to input mode, select channel 1 or 2 and
press the encoder for 3 seconds. The 1st red LED in this channel stops shining.
2. Cable Connection
Connect one or two dynamic microphones to the XLR inputs 1 and/or 2. For
the connection of condenser mics please read the next page.
Attention! Keep in mind, microphones in the vicinity of speakers can cause
loud and dangerous sounds. They can not only damage your hearing but also
your equipment. Always try to keep a safe distance between microphones and
speakers and lower the volume of the Nanoface preamp gain and the output
level before the connection process.
3. Select the channel for the preamp gain
Step 1) Switch to input 1/2 mode.
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.
Test the mic: you should see activity on the meters of the LED chain. Channel 1: left LEDs; Channel 2: right LEDs.
The encoder now controls the gain for both XLR inputs on the breakout cable. If you want to set a different
gain for every mic continue with step 2.
Step 2) Press and hold the encoder. Turn it to the left for channel 1 or turn it to the right for channel 2.
After a 1-click turn, the 1st green LED of the left or right channel blinks one time to show, which channel is
selected. To switch back to the 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.
4. Set the preamp gain
Turn the encoder gradually to the right to raise the gain for the selected input(s).
Make sure the input signal is not clipping (red top LEDs turn on). For an exact control of the available headroom
to the clipping border please use the level meter readouts in your audio software.
4. Record the signal from the microphone on the computer
To record the microphone signal in your audio software, choose the Nanoface as audio interface, create
a mono track and choose channel 1 as input. For a mic on input 2 create another mono track and choose
channel 2 as input.
The Nanoface provides 2 XLR microphone
inputs with optional phantom power (48V)
on the breakout cable.
Microphone signals are low level signals and
need a preamplifier to boost them to a usable
line-level signal. The Nanoface provides two
mic preamps on input 1 and 2 for any kind of
microphone type and level. Both inputs are
equipped with preamps of up to 50.5 dB gain.
If input 2 is switched to the instrument input on
the right side of the Nanoface (guitar symbol),
it’s possible to connect only one microphone
to input 1. Input 2 on the breakout cable is off.
