Setup and Operating Instructions
1. Select a proper channel for your area as indicated in the previous section. Set both the
receiver's and the microphone's channel by adjusting their channel select switches (with a
small flat-blade screwdriver) so they’re both set to the same channel number.
2. Connect the supplied antennas. Vega recommends an upright “V” orientation (similar to
that used with the “rabbit ears” type TV antenna). For additional information regarding
antennas, see the following “Antennas” section.
3. Attach the power cord to the receiver and plug into the ac power source.
4. Attach your audio cable to the rear-panel XLR audio-output connector. Connect the
opposite end to your audio equipment (mixer console, recorder, etc.). The receiver output is
balanced; for single-ended (unbalanced) applications use only pins 1 (common) and 2 (L1)
or use the 1/4" output. The output level in this mode will be 6 dB less than for the balanced
mode. Do not connect either pin 2 (L1) or pin 3 (L2) to ground (common) at any time.
Depending on local grounding conditions, the output can be normal (ground at center of
valence), lifted (third wire is active but not grounded inside receiver) or balanced (with third
wire open).
5. Turn on the receiver by sliding the front-panel power switch; the LEDs should illuminate.
6. Insert a 9-volt battery into the transmitter and turn it on. The LED indicator should flash
briefly upon turn-on; this indicates that the battery is installed properly. If the green LED
remains on the battery is low and should be changed.
7. Observe the RF-level meter (or bargraph) on the receiver. The meter should read well
above midscale when the transmitter is within a clear 50-foot radius of the receiver; if it
doesn’t, difficulties are indicated (refer to the “Troubleshooting” section).
8. Turn on the microphone audio. Begin speaking into the microphone. The audio should be
audible on the associated monitoring equipment.
9. “Walk” the coverage area to ensure there are no areas of poor coverage. If “dropout”
occurs (little or no signal in small areas), repositioned the receiving antenna(s) to eliminate
the problem. Often, a change of just a few inches in location will completely solve the
problem. If problems occur please see the “Troubleshooting” section.
To move antennas to the front of the receiver
To move a R-2020's antenna's to its front panel: 1) remove the two screws shown below
(bottom panel closest to the front of the receiver); 2) unscrew the antenna hex nuts, audio
output nut, and two small screws from back plate; 3) gently slide the PCB out; 4) pop out
the antenna plugs in front of the receiver 5) carefull move the antenna connector to the front
plate and insert connectors threw hole; 6) screw hex nuts back on and slide PCB back in;
pop plugs into antenna holes in back plate and screw audio out and small screws back into
back panel.
