Nowsonic USB Pre Pen features an internal XLR socket (1) for connecting
a microphone (not supplied) to the audio interface. On the front, USB
Pre Pen has a 48 V button for phantom power (7), so you can use dyna-
mic as well as condenser microphones. When phantom power is on, the
+48 (8) LED lights up. Please turn off the phantom power when using a
dynamic microphone to reduce power consumption.

Using the supplied USB cable, connect the USB mini connector (10) in
the base plate of USB Pre Pen with your computer (Mac or PC). Next, USB
Pre Pen is automatically detected by the operating system, no separate
driver installation is required. When the communication with the com-
puter is established, the USB LED (9) lights continuously green. In addi-
tion, USB Pre Pen is Bus powered via this connector: there is no need for
an additional power supply.
The MIC GAIN knob (3) on the front controls the mic gain for the inter-
nal pre-amplifier and for the recording software. A three-color LED (2)
serves as a level meter:
if no mic is connected, the LED is not lit.
If the LED lights green, a signal with a level range from -30dB to -12dB
FS is detected.
For maximum audio quality, the mic level should be set so that the LED
remains steady green, flashing yellow at peak levels (-12 to 0dB FS).
If the LED flashes red, lower the Mic Gain. In this case, the 0 dB level
limit is reached and the converted signal is clipping.
Please make sure to check the gain also with the on screen meters of the
recording channel in your host software.
Connect your stereo headphones to the 1/8" TRS jack (4) on the base
plate. The headphone level is adjusted via the VOLUME knob (5) on the
front of USB Pre Pen. Alternatively, you can connect USB Pre Pen via this
socket to an external monitoring system.
