[. . . ] PEM-500 Wireless Personal In-Ear Monitor 16 Channel UHF PLL Synthesized OWNER'S MANUAL CONTENTS INTRODUCTION Thank you for purchasing a Nady PEM-500 Wireless Personal In-Ear Monitor System and congratulations on your choice. This system offers all of the advantages of wireless in-ear monitoring­mobility, more focused audio, freedom from feedback, and elimination of transport issues associated with conventional floor monitors­as well as the longterm health benefits of safe listening levels. For the first time, a 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 PEM-500 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 will avoid possible loud transients in the PEM500R receiver if it is already turned on, and with earphones plugged into the user's ears. ) 2. Powering the Transmitter Plug the 14V AC ADAPTER (3) provided into the AC INPUT JACK (4) on the back of the receiver. Then plug the power supply into an AC outlet. Press the POWER SWITCH (5) once to turn on the transmitter. The POWER ON LED (6) will now light and the transmitter is operational. 3. Antenna Connect the ANTENNA (7) or optional remote antenna on the back panel to the ANTENNA JACK (8). For maximum range, it is always best to maintain a line of sight (no obstructions) between the transmitter antenna and the receiver(s) at all times whenever possible. 6 7 5. Selecting a Channel/ Multiple System Operation Both the PEM-500T transmitter and PEM-500R receiver offer a choice of 16 channels in the UHF band. Select an open frequency that doesn't interfere with any other PEM-500 or UHF wireless mic system you are also using by pushing the CHANNEL SELECT BUTTON (13) on the front panel of the PEM-500T until the channel you want is displayed on the CHANNEL LED DISPLAY (14). You will also need to select the same channel for the transmitter (see Transmitter Operation instructions above). If different mixes are required for the different performers, additional PEM-500T transmitters and receivers set to other channels must also be used, and each transmitter must be fed a different mix from the console as desired. Depending on the band(s) you are using and open channel availability within the band(s), up to 8 PEM-500 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) [Note: After selecting a frequency on the transmitter, you must also check with the receiver to ensure that the chosen channel is open (i. e. , no other transmissions from other sources, such as UHF TV channels in your area, operating at the same frequency). Turn off the PEM-500T transmitter, and monitor the signal from the PEM500R (see PEM-500R instructions, pg. For optimum operation and range, if you receive any transmissions or static you must choose another channel that is clear. ] [Note: If, after you complete the set-up, 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 mics being used or move their receivers physically away from the PEM500T transmitter. In some instances, UHF wireless mics and the PEM-500 system can interact if they are too close in frequency. Contact the NADY SYSTEMS Service Department for further information if necessary (see SERVICE, pg. 15)] 6. Adjusting Levels Adjust the selected audio input level for optimum level for transmission with the LEVEL CONTROL (12). Adjust the control so that the top LEDs on the 10-segment Left and Right LED LEVEL DISPLAYS (15) light intermittently only on loud peaks. This control adjusts both the left and right signals simultaneously in the same manner. For added control and separate levels on stereo inputs, use the left and right stereo monitor output level control on your console providing the signal. [. . . ] Testing Receiver Range Wearing your receiver and earphones, walk around the stage area and listen for audio quality. Depending on room size, obstructions, amount of reflective metal surfaces, and other conditions that may affect RF transmission, it is normal that the audio may disappear or "drop out" in certain locations. Such zones, otherwise known as "null spots" are very small and fixed in location if you are within 100 feet of the transmitter, and will become larger as you approach the ultimate range of your system in that location (up to 300 or so feet, depending on site conditions). Generally, it is possible to eliminate such "null spots" by moving your PEM-500T transmitter as little as 12-18 inches in any direction. [. . . ]
