OPERATING MANUAL

INTRODUCTION

Thank you for purchasing the Carvin PM1000 Wireless Personal In-Ear Monitor System and congratulations on your choice. This system offers all of the advantages of wireless in-ear monitoring–mobility, freedom from feedback and elimination of transport issues associated with conventional floor monitors–as well as the long term health benefits of safe listening levels. This wireless in-ear monitor system combines state-of-the-art advanced frequency-agile PLL synthesized UHF technology, high-end performance, ease of use, and unprecedented affordability. The PM1000 offers a choice of 16 user selectable UHF channels in both the transmitter and receiver(s), as well as stereo (MPX system) or mono mode transmission. This system is indispensable for live-stage music performance, and is loaded with features previously found only in units costing several times more.

WARNING
USING THIS SYSTEM AT EXCESSIVE VOLUMES CAN CAUSE PERMANENT HEARING DAMAGE. ALWAYS USE AS LOW A VOLUME AS POSSIBLE.
The Occupational Safety Health Administration (OSHA) has established the following guidelines for maximum time exposure to sound pressure levels (SPL) before hearing damage occurs:
90 dB SPL @ 8 hours
95 dB SPL @ 4 hours
100 dB SPL @ 2 hours
105 dB SPL @ 1 hour
110 dB SPL @ 1/2 hour
115 dB SPL @ 15 minutes
Avoid exposure to 120 dB or greater or irreversible ear damage may result.
(Note: It is difficult to measure the SPL present at the eardrum in live sound applications. The volume present will be affected by the level setting of your PM1001, the ambient stage sound from your other instruments and speakers and fit of your in-ear monitors.)
Use the following guidelines:

1. Turn up the volume to your earphones only enough to hear properly.
   Experiment with your overall mix to get the maximum benefit from your PM1000. Whenever possible, turn the limiter on the PM1001 receiver ON.

2.  Turn down the volume immediately if you experience any pain or hearing discomfort or ringing in the ears after use.

PM1000 TRANSMITTER

1. RACKMOUNTING THE TRANSMITTER
   The PM1000 includes two rack-mount ears that are easily attached for singlespace rackmounting. (Note: Do not mount directly above an amplifier or other source of high heat. Always ensure adequate airflow and heat dissipation in any rack configuration.)

2. ANTENNA
   Connect the two ANTENNA to the front panel BNC ANTENNA JACKS. Optimal antenna position is vertical. For maximum range maintain a line-of-sight (no obstructions) between the transmitter antennae and the receiver(s).

3. AUDIO INPUTS
   The PM1000 transmitter features a LEFT and RIGHT XLR-1/4″ balanced inputs. Stereo monitor mixes from your console can be connected to the LEFT and RIGHT INPUTS with either balanced XLR or 1/4” connectors. Two mono monitor mixes can also be  inserted in this manner.

4. STEREO/MONO SWITCH
   Select STEREO to retain discrete L-R stereo monitor mixes. Select MONO for mono mixes. Mono signals from inputs 1 and 2 are combined and transmitted in mono on both the left and right channels. Note that using balanced XLR cables will provide a stronger signal (+6dB louder than 1/4“ cables).
   CAUTION: When making any connection, make sure that the PM1000
   TRANSMIT LEVEL CONTROL and the console output levels are set at minimum volume before plugging into the transmitter. This will avoid possible loud transients being heard by the person wearing the receiver and earbuds.

5. POWERING THE TRANSMITTER
   Plug the 12V AC/DC ADAPTER provided into the rear DC INPUT JACK on the back of the receiver. Then plug the power supply into an AC outlet. (Note: Any 12-15V DC source with 500mA capability can also be used.)

6. POWER SWITCH
   Press the front POWER SWITCH to turn on the transmitter. The POWER LED will now illuminate.

7. TRANSMITTER CHANNEL SELECTORCHANNEL LED DISPLAY
   Both the PM1000 transmitter and PM1001 receiver offer a choice of 16 channels in the UHF band. Select an open frequency that doesn’t interfere with any other PM1000 or UHF wireless system by turning the small CHANNEL SELECT CONTROL on the front panel of the PM1000 until the channel you want is displayed on the CHANNEL LED DISPLAY. A small screwdriver (one is included) will be required to turn the CHANNEL SELECT control. It is designed this way so the channels aren’t switched accidentally. (NOTE: you must also check with the receiver to set and ensure that the chosen channel is open i.e., no interferance from other UHF sources…see PM1001 RECEIVER on the next page) If different mixes are required for performers, additional
   PM1000 transmitters and receivers set to other channels can also be used.
   Up to 8 PM1000 systems on different frequencies can be operated simultaneously to provide multiple discrete mixes to the performers.
   NOTE: NEVER SET MORE THAN ONE TRANSMITTER TO THE SAME OPERATING FREQUENCY.
   If you experience interference or unsatisfactory audio performance, change the channel until the problem goes away. In the extremely rare circumstance that such a problem persists, turn off all UHF wireless systems being used or physically move their receivers away from the PM1000 transmitter. In some instances, UHF wireless systems and the PM1000 system can interact if they are too close in frequency.

8. ADJUSTING TRANSMIT LEVELS
   Adjust TRANSMIT LEVEL CONTROL for optimum transmit performance. This control adjusts both the left and right signals simultaneously in the same manner. For further control of each signal, use the left and right stereo monitor output level control on your console providing the signal. Adjust the TRANSMIT LEVEL CONTROL on the PM1000 so that the first six GREEN LED indicators light. The top two RED LED’s indicate the signal is near maximum which will result in distortion. Keep your levels from going into the RED RED LED’s.

9. HEADPHONE MONITORING
   The signal being transmitted can be monitored with a pair of headphones via the stereo PHONES JACK. The volume can be adjusted as desired with the MONITOR LEVEL CONTROL.

10. BATTERY INSTALLATION
    Slide down and flip open the BATTERY COMPARTMENT and insert a fresh 9V battery. Observe the correct polarity when installing the battery. The battery should last up to 6 hours, depending on the volume. It is recommended that it be changed every 3-4 hours to ensure continuous optimum performance.

11. POWER SWITCH – LOW BATT LED
    Turn on the receiver with the POWER SWITCH. If the battery is good, the LED will glow RED when the PM1000 transmitter is OFF and GREEN when it is on and tuned to the same channel as the receiver. If the battery is too weak for operation, the LED will flash on and off or not light at all. If this occurs during use, change the battery immediately.

12. RECEIVER VOLUME CONTROL
    This will control the volume sent to the earbuds. It is recommended to start with the volume at minimum when turning on or plugging in the earbuds.

13. RECEIVER CHANNEL SELECTOR
    Use a small screwdriver and adjust the CHANNEL SELECTOR CONTROL (located inside the battery compartment) to the same channel as the transmitter.
    The LOW BATTERY LED will change from red to green when it receives a signal from the PM1000 transmitter. Any number of PM1001 receivers can be used with a single PM1000 transmitter set to the same channel. Although there are individual controls on each receiver allowing different levels of volume, each receiver will receive the same transmitted monitor mix (see Selecting Stereo or Mono Mode Reception below for exceptions). If different mixes are required for the different performers, additional PM1000 transmitters and receivers set to other channels can be used. Each additional transmitter can then be fed a different mix from the console as desired.

14. STEREO/MONO CONTROL
    Switch the STEREO/MONO CONTROL in the BATTERY COMPARTMENT to stereo or mono reception to match the PM1000 transmitter. You can also try different combinations for different applications. For example, if multiple PM1001 receivers are being used with one PM1000 transmitting in stereo, the different performers may select either a stereo mix (which may feature vocals on one side and the rest of the mix on the other), or a mono mix (with the vocals and music mixed together). Such capability adds to the versatility of the system by allowing more personal control of the individual sound received by different performers all listening to the same transmitted mix.

15. KOSS® EARBUD STEREOPHONES
    The PM1001 features a standard 1/8” TRS STEREO EARPHONE MINI JACK. Carvin has supplied KOSS® earbuds as these are renowned for their high-performance in-ear monitoring. The foam cushion will form a custom fit when inserted into the ear. This provides superior comfort and isolation from stage sounds. Additional foam cushions are provided for future use or for a more custom fit. KOSS® earbuds are uniquely designed with a tube that shoots sound into your ear. This results in excellent bass response and superior isloation from stage volume. (Note: Wipe the earbuds before and after each use. Stop using the earphones if they are causing discomfort.)

16. LIMITER ON/OFF SWITCH
    The PM1001 receiver features a switchable limiter to help reduce audio spikes. Such spikes could be dangerous to the user wearing the earbuds. The limiter should be switched ON to ensure protection for the user. Turn the limiter off only if the PM1001 is to be used at low volumes.

MONITORING TIPS

• As with any in-ear monitoring system, be cautious with volume settings as you don’t want your ears to be fatigued or damaged by excessive volume.
•  Use an external compressor on vocals and drums whenever possible. This will also help with controlling transient spikes and allow for a more even monitor mix.
• The KOSS® earbuds will successfully isolate your ears from excessive stage volume. However, it is very helpful to have a single “room mic” mixed in slightly with the monitor mix to restore a “natural” hearing effect while wearing the earbuds. You will be able to isolate your ears from the loud stage volume and keep your in-ear monitor volume lower while still retain the ability to hear the crowd and other band members who are not speaking directly into a mic. Note: to avoid feedback it is recommended that this mic not be mixed in with your main mix. Assign it only to the mix going to the PM1000.
