INTRODUCTION

Congratulations on your purchase of the USM16 SERIES Professional Modular Wireless

System. The USM16 system is available pre-mounted in certain Carvin mixers, or may be

purchased for self-installation with the USM16-KIT (consult Carvin for compatibility).

Your system includes a receiver along with a handheld mic with transmitter (USM16-MC)

or a belt-pack transmitter (USM16-BP) depending on the model purchased. The headworn

mic (UX-HM2), cable for instrument (UX-GT) and Lavaliere mic (UX-LP1) are all available

as additional options to the USM16-BP belt-pack system.

The receiver features true UHF diversity reception. Two antennas feed two completely

independent RF receivers on the same frequency. Automatic logic circuitry continuously

compares and selects the superior signal to provide better sound quality and reduce the

possibility of interference and dropouts. Both the transmitter and receiver have 16 user

selectable channels.

The versatile USM16-BP belt-pack transmitter is designed for use with condenser micro-

phones as well as Hi-Z line instrument pickups. Please note that in multiple-system appli-

cations there must be one transmitter per receiver.

GETTING STARTED QUICKLY

If you’re like most new owners, you’re probably in a hurry to use your wireless system. To

start, you must have a USM16 compatible Carvin product, at least one USM16 receiver, and

the USM16-KIT (includes mounting hardware, circuit board and antennas).

If you have purchased this system seperately, please start with the installation procedure on

the back page of this manual.

If the unit has been pre-installed from the factory, you can follow these brief instructions to

get you going quickly;

BATTERY

Insert 2 fresh AA alkaline batteries into the transmitter.

CHANNEL CHECK

Check that both the transmitter and receiver are set to corre-

sponding channel. If multiple systems are used, each system must be set to their own

channel.

BELT PACK SETTINGS

(USM16BP only) Connect the instrument cable or mic to the

Belt-pack. Set the rear gain switch to -20 for mic or 0 for instrument use. Set the fine

gain control to 12 o’clock. Reduce if distortion occurs.

RECEIVER POWER ON

Turn the Volume control of the receiver down and turn down

the volume on the unit this system is mounted in. Make sure you are plugged in to the

proper AC voltage and turn the power ON. This will power on the USM-16 receiver.

TRANSMITTER POWER ON

Switch the mic or belt-pack transmitter to the “ON”

position. The red “RF” LED on the USM-16 should turn on.

SOUND CHECK

Do a sound check and gradually raise the levels while watching the

AF level indicator. Increase the level until the AF level indicator peaks. This indicates that

maximum transmitter modulation without distortion has been reached. You can adjust

the AF level of the transmitter using the included small screwdriver.

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.

For your records, you may wish to record the following information.
