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 inter-
nal 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 locat-
ed 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 indi-
cator will light up even though the transmitter is not on. With U7000 one of the diversi-
ty 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 immedi-
ately. 

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 pro-
tection 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.
