Quick set-up: System Operation

1.With the transmitter and receiver on, monitor the display screen. Note that the RF (1-100) Bar graph should indicate near the 100 mark. The AF Bar should show very little, if any, indication until you talk or sing into the microphone. While talking or singing in the loudest voice used in performance, adjust the transmitter gain control if necessary to cause the AF Bar Graph to peak near -6 to -3 but not over +3 for best performance.

2.Set the mixer/amp gain.

3.Talk or sing into the microphone or play the guitar at a normal volume. You should hear audio coming out of the system.

4.If using the unbalanced 1/4" output, you may have to adjust the gain (via the control next to the connector on the back panel) to match the level found when singing or playing with a wired connection.

"Quick Set-up" is now complete.

NOTE: Groups 9 and above are set up to work with the other US frequency band (A and B). If you are using a mix of Band A and Band B, scroll down to these groups and use the clearest group.

6.Change Lock-Out: By pressing and holding the UP and DOWN arrow keys together for 3 sec- onds, the SET key is disabled.To reactivate the SET key, simply press and hold the UP and DOWN keys again for 3 seconds. This feature can be useful when the receiver is in a location where unauthorized personnel have access to the receiver.

7.For set up, make sure the mixer or amplifier in- put used for the RE-2 is muted or turned down to a minimum level.

8.Plug an audio cable (not supplied) into the 3 pin XLR or 1/4 inch output of the RE-2.

a.NOTE: The XLR connector is the pre- ferred connection since the output is bal- anced and will be more immune to noise for longer runs of cable although either can be used with good results. If the 1/4 inch connector is used, adjust the output level on the back panel to 12 o'clock (mid- way in the range) to start and adjust later if necessary.

Now refer ahead to transmitter setup and return to step 9 when that is completed.

9.With the transmitter on, speak into the micro- phone or play the guitar. Turn up the level on the mixer or amplifier until you are able to hear the desired signal. If no audio is present, repeat setup and refer to the troubleshooting section.

NOTE: If the 1/4 inch output is used, it may be necessary to adjust the receiver output until the volume level from the wireless system approxi- mates the level of an equivalent wired micro- phone/instrument.

10.Squelch Adjustment - The squelch setting can be used to maximize range or immunity to noise. Press and hold Up for 3 seconds. The cur- rent squelch setting will be displayed. Adjust the squelch using the UP/DOWN keys. Maxi- mum squelch (9) maximizes noise immunity but limits the range. Minimum squelch (1) will maxi- mize the range but allow more noise to break through the squelch. Press SET to save the new squelch setting.
