1. DC Input - Connect the supplied 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 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 dBu) audio equipment. Pin wiring is as fol-
lows: Pin 1 ground, Pin 2 high (hot), and Pin 3 low (cold).
3. MIC/LINE Switch - Sets the audio output level attenuation of the balanced output to -20 dBm
(line level) or -40 dBm (mic level).
4. UNBALANCED OUTPUT* - Use this unbalanced high impedance (5 kΩ) 1/4” jack when connect-
ing the CR77 to consumer (-10 dBV) audio equipment. Wiring is as follows: tip hot, sleeve
ground.
*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.
