4. Pwr/low battery level LED indicator. This LED blinks every 750ms when the unit is connected to an
external power supply thru the Hirose input connector. When the unit is powered from the internal
batteries this LED will turn on. The LED will start to blink every 300ms when the battery voltage is
too low. The user should then replace the batteries as soon as possible. The low voltage threshold
is set to 13V (2 x 6.5V). This threshold is compatible with iPOWERUS 9V rechargeable Lipo
batteries.
5. Audio modulation LED indicators.
6. Batteries compartment. This compartment is designed to receive 9V 6LR61 or PP3 batteries.

potentiometer is deactivated when the "link" push button is engaged (3).
8. Right input gain level
adjustment potentiometer.
Gain can be adjusted from
-50dB to +80dB. This
potentiometer also controls
the gain level of the left input

9. ADC sample rate selector.
Sample rate of the digital
output can be selected from
44.1 to 192kHz with the
rotary encoder. The ADC can
also be shut down to save
battery power.

(crimp style connector). The µPRE MKII can be externally powered thru this connector with a DC
power source ranging from 9 to 18V. Batteries are automatically disconnected when a external
power source is connected. The DC IN input is protected against polarity reversal.
