Guided Tour - UR1 Rear Panel
1: DC input - Connect the supplied 12 volt 160 mA power adapter here, using the strain
relief as shown in the illustration below. WARNING: Do not substitute any other kind of
power adapter; doing so can cause severe damage to the UR1 and will void your warranty.
2: Unbalanced output* - Use this unbalanced high impedance (5K Ohm) 1/4" jack when
connecting the UR1 to consumer (-10) audio equipment. Wiring is as follows: tip hot,
sleeve ground.
3: Audio Output Level switch - Sets the audio output level attenuation of the balanced
output (see #4 below) to -20 dBm (line level) or -40 dBm (mic level). See the “Setting Up
and Using the Series One System” section on page 8 in this manual for more information.
4: Balanced output* - Use this electronically balanced low impedance (600 Ohm) XLR
jack when connecting the UR1 to professional (+4) audio equipment. Pin wiring is as
follows: Pin 1 ground, Pin 2 high (hot), and Pin 3 low (cold).
* If required, both the unbalanced and balanced outputs can be used simultaneously.

Using the strain relief: Gather up a loop of wire and pass it through the strain relief,
then pass the adapter plug through the loop in order to create a knot.
