CARVIN ENGINEERING DATA USM16BP/USM16MC WIRELESS SYSTEMS OPERATING MANUAL
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 microphones as well as Hi-Z line instrument pickups. Please note that in multiple-system applications 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;
1.BATTERY Insert 2 fresh AA alkaline batteries into the transmitter.
2.CHANNEL CHECK Check that both the transmitter and receiver are set to corresponding channel. If multiple systems are used, each system must be set to their own channel.
3. 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.
4. 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.
REGULATIONS AND SERVICING
This device complies with part 15 of the FCC Rules. Operation is subject to the condition that this device does not cause harmful interference.
This device complies with INDUSTRY CANADA R.S.S. 210, en conformite´ avec IC: RSS-210/CNR210.
CAUTION! Electrical shock can result from removal of the receiver cover. Refer servicing to qualified service personnel. No user-serviceable parts inside. Do not expose to rain or moisture. The circuits inside the receiver and transmitter have been precisely adjusted for optimum performance and compliance with federal regulations. Do not attempt to open the receiver or transmitter. To do so will void the warranty, and may cause improper operation.
5.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.
6.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
