1: Antenna A and B mountings- Connect the supplied antennas to these mountings. Third-party receiver
antennas should notbe substitutedN use only the antennas provided with the CR4. See the OSetting Up and
Using the Concert IV System� section on page 6 for more about antenna installation and positioning.
2: Volume- This knob determines the level of the audio signal sent from both the balanced and unbalanced
output jacks on the rear panel.
3: OA�/OB� LEDs- When signal is being received, one of these LEDs will be lit, showing you whether signal from
either the OA� or OB� antenna is currently being used. A computer chip inside the CR4 constantly scans the two
and automatically selects whichever is receiving the strongest, clearest signal. This OMicroprocessor True
Diversity� switching is completely inaudible, and it effectively increases overall range while reducing potential
interference and phase cancellation problems.
4: AF Level meter- This Oladder� display (similar to the VU bar meter used on audio devices) indicates the
strength of the incoming audio signal. When the O100% � segment is lit, the incoming signal is optimized at unity
gain; when the O125% � segment is lit, the signal is overloading. When only the left-most O10% �segment is lit, the
incoming signal is at just 10% of optimum strength. If no segments are lit, little or no signal is being received.
For more information, see the OSetting Up and Using the Concert IV System� section on page 6 in this manual.
5: Squelch control- This control determines the maximum range of the CR4 before audio signal dropout.
It should normally be left at its factory setting. For more information, see the OSetting Up and Using the Concert IV
System� section on page 6 in this manual.
6: Power switch- Use this to turn the main power on and off.

7: Rear-mount antenna knockouts- The CR4 antennas (normally mounted on the front panel) can optionally
be mounted on these areas of the rear panel. Contact Samson or your local distributor for further information.
8: DC input- Connect the supplied AC adapter here. WARNING: Do notsubstitute any other kind of power
adapter; doing so can cause severe damage to the unit and will void your warranty.
9: Balanced output*- Use this electronically balanced low impedance (600 Ohm) XLR plug when connecting the
CR4 to the microphone input of professional (-30 dBm) audio equipment, wired as follows: Pin 1 ground, Pin 2
high (hot), and Pin 3 low (cold).
10: Unbalanced output*- Use this unbalanced high impedance (5K Ohm) 1/4" jack when connecting the CR4 to
the microphone input of consumer (-10 dBv) audio equipment, wired as follows: tip hot, sleeve ground.
* If required, both the balanced and unbalanced outputs can be used simultaneously.
