QUICK START
1. Connect the external power supply (included) to the rear panel connector
labeled “DC input.” Then plug the power supply into an AC outlet.
2. Connect a microphone cable between the Clear-Com line input connector on
the rear panel and the output connector of a Clear-Com PIC-4000 IFB
controller, or alternately, to a Clear-Com intercom system.
3. Set the “input level” switch to the “line” position.
4. Set the rear panel “audio compression” switch to “soft ALC.”
5. Turn on the front panel “power” switch.
6. With an audio input applied to the unit, adjust the front panel “input level
adjust” control until the “audio level” bargraph meter indicates peaks in the 0
to +2 VU range.
7. Attach the earpiece or headset to the RCV-2 receiver.
8. Turn the receiver on by moving the slide switch to the F1 or F2 position.
A short flash of the red “Batt Low” LED indicates a good battery. A steady
LED indicates a weak battery. If the LED does not turn on at all, replace the
battery.
9. Verify operation by switching to F1 or F2 which selects one of two
frequencies.
10.Adjust the volume to a comfortable level.
See Chapter 3 for detailed setup information and for instructions on how to
optimize performance.

OPERATION
DESCRIPTION
UPX-10 WIRELESS TRANSMITTER
The UPX-10 wireless transmitter permits IFB/talent cueing, PL/intercom
listen-only monitoring and other audio monitoring applications for studio, field,
and theatre/live performance environments. The system consists of the UPX-10
base station transmitter and one or more RCV-2 portable beltpack receivers.
The UPX-10 base station is a single-channel rack-mounted VHF/FM
transmitter that sends a monaural audio signal to a compatible receiver such as
the Clear-Com RCV-2 portable VHF receiver. The receiver must exactly match
the transmitter frequency; refer to the identification labels on each piece of
equipment.
The UPX-10 accepts either a Clear-Com intercom line or IFB audio signal from
a Clear-Com IFB controller. It can optionally be set up to accept a mic- or
line-level audio input through the same XLR connector mounted on the rear
panel. The S0-239 RF output connector, sometimes called a UHF type, is also
mounted on the rear panel. The transmitter is powered by means of an external,
wall-mounted power supply provided with the UPX-10. It does not require or
draw power from the Clear-Com system.
The audio signal can be adjusted in various ways prior to transmission in order to
improve intelligibility in demanding acoustic environments. Two
screwdriver-accessed controls for adjusting the low and high frequencies are
located on the rear panel. In addition, the audio dynamic range can be limited by
either a 2:1 logarithmic compressor, or by a wide-range Automatic Level Control
(ALC) system, selected by means of a slide switch located on the rear panel. This
switch also has a third position for no dynamic range modification. Noise
reduction is achieved with a proprietary two-ended compander system that is
always active. The compander is compatible with Clear-Com’s RCV-2 portable
VHF receiver.
Note:The UPX-10 is shipped from the Clear-Com factory with internal jumpers set
to be compatible with Clear-Com wired intercom and IFB systems.
The UPX-10 can also accommodate a wide range of audio input levels. A
two-position slide switch attenuator on the rear panel selects between mic (-40 to
-10 dBu) and line (-10 to +20 dBu) levels. Fine audio level adjustment is made
by means of a 30-dB range-variable attenuator conveniently located on the front
panel. Also located on the front panel is an 8-segment LED VU meter to assist in
adjusting input levels.
The RF transmitter portion of the UPX-10 is a replaceable printed circuit board
assembly (PCB) that plugs into the main UPX-10 PCB. This crystal-controlled
transmitter is factory tuned to a specific frequency, and can easily be replaced
• The system consists of the
UPX-10 base station
transmitter and one or
more RCV-2 wireless
beltpack receivers.
• The UPX-10 accepts
either a Clear-Com
intercom line or IFB audio
signal from a Clear-Com
IFB controller.
• The audio signal can be
adjusted prior to
transmission.

with another transmitter strip to allow operation on a different frequency. The
transmitter is available set to any of over 1,600 different frequencies between 169
MHz and 216 MHz. This frequency must be pre-set at the factory. It is not field
adjustable. Consult your dealer or the Clear-Com factory for details on
frequency coordination and changes.
A 1/4-wave “whip” antenna is provided with the UPX-10. Other antennas, such
as the Clear-Com Model 123U dipole antenna may be used to facilitate rack
installation or to improve coverage where the standard whip antenna would
otherwise be blocked or shielded by equipment cabinets or large objects.
RCV-2 WIRELESS BELTPACK RECEIVER
(MODELS RCV-2, RCV-2S, RCV-2D)
The Clear-Com RCV-2 wireless receiver is a miniature portable device normally
worn on the body of the user. Small and lightweight, it operates from a single
9-volt battery for 8-10 hours of operation. It features a low-battery indicator and
rechareable battery operation. It is useful for a variety of one-way personal
communications purposes.
The RCV-2 operates in the high-band VHF frequency range of 169 to 216
MHz. Systems employing the RCV-2 require licensing under FCC Part 90 or
Part 74. It is compatible with the Clear-Com UPX-10 and WBS-6/600
transmitters.
Note: Any change or modification made to this product without the express written
authorization and approval from Clear-Com could void the user’s authority to operate
this equipment.
The RCV-2 may be ordered with either one or two frequencies installed, and is
switchable between those frequencies for maximum flexibility.
OPERATION
UPX-10 TRANSMITTER
The UPX-10 transmitter is intended to be used only with the Clear-Com RCV-2
wireless beltpack receiver (Models RCV-2, RCV-2S, and RCV-2D). The UPX-10
transmitter is not compatible with receivers from other manufacturers.
Frequency Selection
You must choose a transmit frequency for the UPX-10 that can coexist with
other RF systems in the coverage area. This frequency must be specified at the
time of purchase. The Clear-Com factory provides a frequency coordination
service free of charge for this purpose.
Note: There are restrictions on the use of specific frequency ranges by certain types of
users. If you do not understand these restrictions or are uncertain of their applicability,
consult your Clear-Com dealer or the Clear-Com factory.

Receiver Parts
Headphones and Earpieces
The RCV-2 receiver is supplied with a generic earpiece for utility and testing
purposes. Devices with impedances as low as 8 Ohms may be used if extremely
high audio output is necessary, but battery life may be relatively short. Units with
impedances in the 25 to 125 Ohm range are preferred, as they will usually give
adequate output and longer battery life.
Battery
The RCV-2 requires a 9-volt battery. A good quality alkaline battery will provide
the best service and the highest reliability.
Rechargeable 9-volt batteries (“ni cads”) may be used in the RCV-2. Battery life
will be considerably shorter than for alkaline batteries, since the capacity of ni
cad batteries is only about 20% that of alkalines.
The RCV-2 has external contacts to permit recharging an internal ni cad battery.
An optional “drop-in” charger is available that allows the RCV-2 to be recharged
without removing the battery, and without disconnecting or dissassembling the
headset.
Antenna
The RCV-2 receiver uses the headset or earpiece cable as the antenna. For best
performance and range, the cable should be from 24 to 40 inches (0.6 to 1
meter) long. Coiling or twisting up the cable along its length may reduce the
range of the system greatly. If the headset cable is longer than 40 inches (1 m)
and you do not want to shorten it, roll up the excess cable about 36 inches
(0.9 m) away from the plug which connects it to the RCV-2.
Beltclip
The RCV-2 receiver is equipped with a sturdy metal clip that can be used to
attach it to a belt, pant pocket, strap, or the like. If you want to carry the unit in
a pocket, the belt clip is easily removed. Simply unscrew the two Phillips-head
screws, visible through the holes in the clip, and remove the clip. Be sure to save
the belt clip and screws in case the clip is needed again in the future.
