CARVIN PM100 WIRELESS User manual

1
Important Note
Just as with any in-ear monitor system, the PM100 works
best when used exclusively by all the performers on
stage—without any wedges or side monitors. The high
sound pressure levels produced by floor monitors (espe-
cially if the band plays loud) can bleed through the in-ear
monitor earbuds, in the worst cases, thus hindering their
effectiveness. Experiment with your mix to get the maxi-
mum benefit from your PM100.
Carvin, manufacturer of guitars, amps, and pro sound equipment since
1946, proudly presents the PM100 Professional Ear Monitor Wireless
System. The PM100 provides in ear monitoring to on stage performers
or behind the scenes personnel. The system is designed to be very easy
to use and requires no installation.
The PM100 consists of one wireless transmitter and one or more wire-
less bodypack receivers on the same channel. The transmitter features
three factory preset channels (AA: 72.1 MHz, EE: 72.9 MHz & HH: 75.9
MHz) with wide band modulation for quality audio. These frequencies
are in a separate band that will not interfere with simultaneous use of
VHF or UHF wireless systems on the same stage.
The PM100 system has a wireless operating range of 300 feet, which
allows it to be used with confidence in venues from small clubs to large
theatres.
The transmitter connects to a monitor or line out from any mixing con-
sole, and broadcasts the audio as an FM signal to any number of pocket
size PM100 receivers on the same channel. Each receiver is equipped
with an adjustable volume control, and high performance earbuds. The
transmitter also provides a microphone input to allow wireless cueing of
the performers on stage.
The PM100 can provide a high quality monitor mix at significantly lower
decibel levels than floor monitors. This is an important benefit for artists
who wish to protect their hearing from excessive and potentially damag-
ing sound pressure levels. Please read this manual completely before
using your PM100.

Audio Input Gain Adjustment
You can quickly adjust the transmitter to obtain optimum performance with the
input gain control. The audio modulation indicator LED, marked “TX” will increase
in brightness as the control is turned clockwise, and decrease in brightness as
the control is turned counterclockwise. When the “TX” LED is flashing during
transmission, the transmitter is broadcasting properly. (If the LED stays off contin-
uously or barely flashes at all, the input gain needs to be increased. If the LED
stays on continuously and does not flash during modulation, the input is overload-
ing and needs to be decreased.) You will also need to test the transmitter in use
with an PM101 receiver. This procedure is easy to do, and is explained in the
receiver instructions, which follow.
Using More Than One PM100 System
You may operate up to three PM100 systems in the same location. For example,
you may want to use one transmitter to provide a mix to the rhythm section, a
second to provide a different mix for the vocalist. For multiple system operation,
please observe:
• If operating two or more PM100 transmitters in the same location, be sure your sec-
ond transmitter is set for a different channel. This should be requested at the time of
purchase since the channels are preset at the factory .
• Locate the transmitters ten feet or more, away from the performers using receivers.

PM101 RECEIVER
The PM101 receiver is a pocket sized wireless audio receiver with an output for
earbuds to provide in ear monitoring, and offers these features:
• Ultra compact and lightweight
• Pretuned to one of three channels in the 72-76 MHz range
• Loudness adjustable with volume control
• Antenna is integral with earphone cord
• A pair of mini binaural earphones included
• LED “power on” indicator
• Accepts standard, alkaline or rechargeable NiCad 9V batteries
Channel Selection
Your receiver is pre tuned at the factory to the same channel as your transmit-
ter. Should you wish to have your transmitter channel changed, as explained in
the Transmitter section of this manual, you must also have your receiver(s)
retuned as well. Contact Carvin’s Service Department (800-854-2235).
Powering The Receiver
Install a 9V battery in battery compartment, observing polarity. To preserve bat-
tery life, always turn the receiver off when it is not in use. When the sound
becomes weak or distorted, replace the battery. The number of hours of opera-
tion per battery is as follows: Carbon zinc type battery: 10-12 hours. Alkaline bat-
tery: 17-20 hours. Rechargeable: 6-8 hours per charge, varies by manufacturer.
Note: Any commerical 12V DC 100 mA adapter can also be used as a receiv-
er NiCad battery recharger. To recharge a NiCad battery, you can plug the 12V
DC adapter into the PM101 receiver’s earphone/charger jack.
CAUTION: The only way you can recharge a NiCad battery while it is installed in the receiver is
with a 12V DC adapter. You cannot plug a commercial 9V DC recharger into the receiver. You can
use such a 9V DC recharger to recharge a NiCad battery, but you must first remove the battery
from your PM101 receiver.
WARNING: Never recharge a carbon or alkaline battery is installed in the receiver, as any
attempt to do so may seriously damage the receiver, cause the battery to explode or start a fire.
A 12V DC adapter recharger may be plugged into your receiver only when a rechargeable battery
is installed in the receiver.
USING THE EARBUDS
Simply plug the included earbuds into the mini-jack on top of the receiver. Note:
Proper sound levels on stage are essential for optimum effectiveness of any in-
ear monitor system. (See also “Important Note” on page 1). If sound levels are
high, it is important to properly seal out unwanted sound so the earbud can be
effective in providing proper monitoring. High end high priced in-ear monitor
systems use special transducers that are imbedded in a soft plastic custom
mold of the users ear canal. This ensures a perfect fit and seal with maximum
immunity from bleed through. Such ear mold speakers are very expensive and
can be used with the PM100 for optimum results.The earbuds supplied with the
PM100 offer great sound and can also provide top results if utilized properly. If
sound pressure levels are high and bleed through is a problem, care must be
taken to ensure proper fit and a tight seal.

Operating the Receiver
While wearing your earbuds, turn the receiver on by rotating the On/Off Volume
wheel. The power on indicator will go on. (To turn the receiver off, rotate the
On/Off/Volume wheel until it clicks, and the “power on” indicator will go out.)
Adjusting Ear Monitor Volume
Listen for your program source, and adjust receiver volume to a comfortable lis-
tening level. The PM101 receiver is capable of providing listening levels loud
enough to be heard in use with a rock band. Many bands use on stage loudness
levels that with repeated exposure could pose a threat to their hearing.
Therefore, it is very important that the PM101 be used at a reasonable and com-
fortable listening level.
NOTE: A slight hum may be heard if the receiver is used within six feet of the
transmitter. This is normal and does not affect performance.
Testing Receiver Range
Wearing your receiver and earphones, walk around the stage area (and sound
board and other areas if crew members are to be equipped with receivers) and
listen for audio quality. In certain areas of the room the audio may disappear or
“drop out.” This is a normal occurrence whenever radio signals are transmitted
inside a building. If you step away from the “drop out” zone, the audio will return.
If a drop out zone is within the area of the stage or sound board(s), it is possible
to eliminate the drop out zone by moving your PM100 transmitter as little as 12-
18 inches in any direction. After you move the transmitter, “range walk” the stage
and other areas again to check for consistent reception.

PM100 TRANSMITTER
The PM100 transmitter is a compact transmitter that broadcasts on one of
three factory preset channels (AA: 72.1 MHz, EE: 72.9 MHz & HH: 75.9 MHz), to
any number of Carvin wireless bodypack receivers on the same channel. The
system provides a 300 ft. wireless operating range, and offers these features:
• Rear panel input for line level audio
• Front panel input for microphone
• Audio input gain control
• Automatic level control
• Extendable antenna
• 12 volt DC input for included AC power supply
• Power switch with red LED power on indicator
• Audio modulation LED indicator
• Rugged, metal housing, rack mountable with optional rackmount kit 200R
Setting Up the Transmitter
Your PM100 requires minimum installation. Simply place the transmitter on any
flat surface, connect your mixing board to the transmitter’s back panel input (See
connecting Audio input below), connect the included power supply (as explained
below), and the transmitter is ready to broadcast to any number of PM101 receivers
operating on the same channel. The PM100 transmitter can also be quickly and
easily installed in a single rack space with an optional rackmount kit (200R).
Powering the Transmitter
Connect the AC adapter provided into the 12V DC jack on the back panel of the
transmitter. Plug the other end into an AC wall socket. Press power switch. The
“power on” LED will light.
Antenna
Extend antenna fully and position 90 degrees from top of the transmitter.
CONNECTING AUDIO INPUT
The Line In jack on the rear panel lets you connect the PM100 to your mixing
console. This 1/4” mono phone jack accepts an unbalanced line level audio
source at zero dBm nominal signal level. If your mixer has XLR outputs only, you
will need an XLR-to-1/4” transformer, available from Carvin (MTF60).
USING A MICROPHONE
The Mic jack on the front panel allows wireless cueing of on stage performers.
IMPORTANT: This 1/4” mono phone jack is designed for an electret condenser
microphone, and 9V DC power is present at the input jack. If you wish to use a
conventional dynamic microphone a preamp should be used. If a preamp is
used, be sure to have a blocking capacitor (1 µƒ) between the preamp output
and the PM100 mic input. If a dynamic mic is plugged into the mic input by mis-
take, there should be no damage because the current is limited to 1.0 mA. If you
have any questions, contact Carvin’s Customer Service 800-854-2235.
