INTRODUCTIONS

Congratulations on your purchase of the U7000 and U7500 Professional Wireless System. These systems include a receiver and either a Lavaliere mic, a handheld mic with transmitter, a headworn mic, or a body-pack transmitter for guitar,.

The receiver features true UHF diversity reception. Two antennas feed two completely independent RF sections on the same frequency. Automatic logic circuitry continuously compares and selects the superior received signal providing better sound quality and reducing the possibility of interference and dropouts. Both receivers are made to be mounted in a standard 19” rack (1U).

The versatile body-pack transmitter is designed for use with condenser microphones as well as Hi-Z instrument pickups. Both the handheld and body-pack transmitters use internal antennae.

Please note that in multiple-system applications there must be a transmitter-receiver

combination on a separate frequency for each input desired (one transmitter per receiver).

GETTING STARTED QUICKLY

If you’re like most new owners, you’re probably in a hurry to plug your wireless system in and use it. Here are some brief instructions to get you going quickly. With the wireless system unplugged and the unit turned off, complete the following procedures:

1. ANTENNAS

Assemble the two antennas to the BNC connectors. For the U7000 the BNC connectors are located on the front. For the U7500, the BNC connectors are located on the rear. For rackmount installation of the U7500, the extension cables provided bring the antenna inputs to the front of the receiver for mounting.

2. FREQUENCY CHECK

Check the frequency of the system against the chart on the back page to ensure you have the proper frequency for your area. The frequency is marked on the back panel or bottom of the receiver.

3. OUTPUT CONNECTIONS

There are two audio outputs on the back of the receiver:

balanced XLR and unbalanced 1/4”. Connect the appropriate cables for your system.

4. POWER CONNECTIONS

Connect the included AC adapter to the DC power input on the back of the receiver. Then plug the adapter into a standard 120 volt 60 Hz AC power outlet.

5. RECEIVER POWER ON

Turn down the Level control of the receiver as well as the mixer. Switch on the receiver only. Do not switch on the transmitter yet. The power indicator will light up even though the transmitter is not on. With U7000 one of the diversity indicator LEDs (A or B) will also light up.

6. TRANSMITTER SETTINGS

Slide the battery cover off of the transmitter and adjust

the input switch to the appropriate setting; 1=Instrument, 2=headmic, 3=lav mic.

7. BATTERY SELECTION

Insert a fresh 9-volt alkaline battery, observing the correct

polarity. Reinstall the battery cover.

8. TRANSMITTER POWER ON

The transmitter has a 3-position power switch; “Off”,

“Stand-by”, and “On”. Switch the transmitter to the “on” position.

9. SOUND CHECK

Do a sound check and gradually raise the level while watching the AF level indicator. Increase the level until the AF level indicator peaks. This indicates that maximum transmitter modulation without significant distortion has been reached.

10. SQUELCH

To eliminate unwanted background RF noise adjust the squelch control. Hopefully, this will help get you started. Have fun with your new U7000/U7500 wireless system.

RECEIVING INSPECTION—read before getting started

INSPECT YOUR WIRELESS SYSTEM FOR ANY DAMAGE which may have occurred during shipping. If any damage is found, please notify the shipping company and CARVIN immediately.

SAVE THE CARTON & ALL PACKING MATERIALS. In the event you have to re-ship your unit, always use the original carton and packing material. This will provide the best possible protection during shipment. CARVIN and the shipping company are not liable for any damage caused by improper packing.

SAVE YOUR INVOICE. It will be required for warranty service if needed in the future.

SHIPMENT SHORTAGE. If you find items missing, they may have been shipped separately.

Please allow several days for the rest of your order to arrive before inquiring.

RECORD THE SERIAL NUMBER on the enclosed warranty card or below on this manual for your records. Keep your portion of the card and return the portion with your name and comments to us.

RECEIVER

FRONT PANEL FEATURES

1. POWER SWITCH Depress to power the receiver. The RED led indicates power to the unit.

2. LEVEL CONTROL Adjusts the audio level to your amp or mixer. If distortion occurs, reduce the level.

3. SQUELCH CONTROL The squelch control is preset at the factory, but can be adjusted if you must use the system in an area with considerable RF interference. If there is audio output from the receiver when your transmitter is off, adjust the squelch control so the system will receive the signal from your transmitter but “squelch” or eliminate the unwanted background RF noise. This adjustment can cause a reduction in useable range of the wireless transmitter, so set the control to the lowest position that reliably mutes the unwanted RF signals.

4. ACTIVE DIVERSITY CHANNEL LED (On U7000 UHF Receiver only) The A and B LED indicate which antenna signal is being used. This diversity receiver will automatically choose the stronger of the two.

5. AF LEVEL LED The AF level is displayed by an LED meter, which indicates the strength of the audio signal received.

6. RF LEVEL LED The RF level is displayed by an LED meter, which allows you to estimate the RF power with which a transmitted signal is received. If less than 2 LED, reception will become noisy.

7. ANTENNA “A” Antenna for receiver “A.”

8. ANTENNA “B” Antenna for receiver “B.”

9. MOUNTING ADAPTERS For mounting the receiver in any stan-

dard 19” rack, attach adapters to receiver with screws supplied.

FRONT & REAR PANEL CONTROLS

1. Use only fresh alkaline batteries.

2. Position the receiver so that it has the fewest possible obstruction between it and the normal location of the transmitter. Line-of-sight is best.

3. The transmitter and receiver should be as close together as conveniently possible.

4. The receiver antenna should be in the open and away from any metal or cement walls. If in a rack, have the unit on top or angle antennas outward away from the metal rack.

5. A receiver cannot receive signals from two transmitters at the same time.

6. Each transmitter/receiver system operates on a factory-aligned, crystal co trolled frequency. Look on the back of the receiver to obtain the channel number. This number must match the transmitter if you purchase a replacement transmitter.

7. Turn the transmitter off when not in use. Remove the battery if the transmitter is not used for a period of time.

TIPS TO OBTAIN THE BEST RESULTS

REAR PANEL FEATURES

10. ANTENNA JACK “A” Antenna connector for receiver ”A.” Attach the antenna directly or extend it with an antenna cable for front mounting.

11. ANTENNA JACK “B” Antenna connector for receiver “B.” Attach the antenna directly or extend it with an antenna cable for front mounting.

12. DC POWER INPUT Use AC power adapter, which supplies 12V DC.

13. OUTPUT LEVEL If the signal going to your amp or mixer is too loud or

distorted, set the output level to Low. If you lack volume, set the switch to High.

14. FUSE Turn the unit OFF and unplug the power supply before checking or replacing the fuse. Use a philip screwdriver to remove the fuse holder. Replace the fuse with the same rated fuse.

15. UNBALANCED AUDIO OUTPUT JACK 1/4” phone jack. Can be connected to an unbalanced input of a mixer or tape recorder.

16. BALANCED AUDIO OUTPUT JACK XLR-type connector. A standard 2-conductor shielded cable can be used to connect the receiver output to a balanced input on a mixer.

17. FREQUENCY CODE The transistor and receiver must have the same frequency number.
