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.
1: DC input - Connect the supplied 12 volt 160 mA power adapter here, using the strain relief as
shown in the illustration beloWARNING:w D. o not substitute any other kind of power adapter;
doing so can cause severe damage to the CR77 and will void your warranty.
2: Balanced output* - Use this electronically balanced low impedance (600 Ohm) XLR jack
when connecting the CR77 to professional (+4) audio equipment. Pin wiring is as follows: Pin 1
ground, Pin 2 high (hot), and Pin 3 low (cold).
3: Audio Output Level swit - Sets the audio output levchel 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
