HELP SECTION
RF Interference
If you encounter receiving interference (from other than an operating TV station), often it can be
eliminated by adjusting the receiver’s squelch control, as described in this manual.
Please note that wireless frequencies are shared with other audio services. According to Federal
Communications Commission regulations, “Wireless microphone operations are unprotected from
interference from other licensed operations within the band. If any interference is received by any
Government or non-Government operation, the wireless microphone must cease operation…”
If you need assistance with operation or frequency selection, please contact Carvin’s service
department.

INTRODUCTION
Thank you for choosing a Carvin professional wireless system. You have joined thousands
of other satisfied customers who have chosen our products because of their quality, per-
formance and reliability. This Carvin wireless microphone system is the successful result
of years of design and manufacturing experience.
This professional wireless system includes a receiver and either a body-pack or a hand-
held transmitter on a specific crystal-controlled frequency.
The receiver features true diversity reception. Two antennas feed two completely inde-
pendent RF sections on the same frequency; automatic logic circuitry continuously com-
pares and selects the superior received signal, providing better sound quality and reducing
the possibility of interference and dropouts. The receiver is made to be mounted in a stan-
dard 19” rack (1U).
The versatile UniPack™ body-pack transmitter has both low- and high-impedance inputs
plus a bias connection, for use with dynamic and electret condenser microphones, as well
as Hi-Z instrument pickups. Both the handheld and UniPack transmitters use internal 9-
volt batteries and have Off/Standby/On switches, battery condition indicators, and battery-
save switches.
Please note that in multiple-system applications there must be a transmitter-receiver com-
bination on a separate frequency for each input desired (only one transmitter for each receiver).
Because the wireless frequencies are in or near VHF TV frequencies, only certain wireless
frequencies are useable in a particular geographical area. Also, only certain of the available
operating frequencies may be used together. (Frequency selection information will be found
on the back cover.)
INSTALLATION AND OPERATION
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. Operation is subject to the following conditions: 1) This device may not cause
harmful interference and 2) this device must accept any interference received, including inter-
ference which may cause undesired operation.
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.
RECEIVER INSTALLATION
LOCATION
For best operation the receiver should be at least
3 ft. above the ground and at least 3 ft. away from
a wall or metal surface to minimize reflections. The
transmitter should also be at least 3 ft. away from
the receiver, as shown in figure A.
Keep antennas away from noise sources such as
motors, automobiles, and neon lights, as well as
large metal objects.
For your records, you may wish to record the following information.

RECEIVING INSPECTION—read before getting started
INSPECT YOUR WIRELESS SYSTEM FOR ANY DAMAGE which may have occurred during ship-
ping. 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 protec-
tion 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.
OUTPUT CONNECTIONS
There are two audio outputs on the back of the receiver: balances (220 mV) and unbal-
anced (350 mV). Use shielded audio cable for the connection between the receiver and
the mixer. If the input of the mixer is a 1/4” jack, connect a cable from the 1/4” unbal-
anced audio output on the back of the receiver to the mixer. If the input of the mixer is an
XLR-type input, connect a cable from the balanced XLR-type audio output on the back of
the receiver to the mixer.
The two isolated audio outputs permit simultaneous feeds to both unbalanced and bal-
anced inputs. For example, both a guitar amp and a mixer can be driven by the receiver.
ANTENNAS
Assemble the two whip antennas to the special connec-
tors provided. Screw the whips into the threaded side holes
at the rear of the connector (Fig. B).
Attach the antennas to the antenna input jacks. The anten-
nas are normally positioned in the shape of a “V” (45° from
vertical) for best reception.
Do not try to move the antenna rod after the connector shell
has been tightened down. Always loosen the connector shell
completely before repositioning the rod.
If there is not sufficient space above the receiver and/or if
the receiver is installed in a metal cabinet, the antennas can be mounted in the threaded
holes in the back of the connectors so the antennas will stick straight out from the back of
the receiver. Use one set of threaded holes or the other; do not attempt to bend the antenna
rods. (The optional accessory PWS-RMA rack-mount antenna kit brings antenna inputs to
the front of the receiver.)
POWER CONNECTIONS
Connect the included AD1205A 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.
