Guided Tour - CR77 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 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 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 
Concert Series System” section on page 8 in this manual for more information.

4: Unbalanced output*

 - Use this unbalanced high impedance (5K Ohm) 1/4" jack when con-

necting the CR77 to consumer (-10) audio equipment.  Wiring is as follows: tip hot, sleeve ground.

*

  If required, both the unbalanced and balanced outputs can be used simultaneousl

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.
