YQESV-301FTFM Wireless Transmitter

USER’S MANUAL: SUPREMEVISION LARGE AREA FM WIRELESS TRANSMITTER Model No.: SV‐301FT Important Safety Instructions Read all instructions in this guide before installing and using the equipment. Use the supplied power supply with the equipment. Plug the power supply into an appropriate, grounded power outlet. Keep the equipment away from water and moisture. Avoid dropping anything on the equipment. Do not attempt to service the unit yourself. Contact your dealer or Supreme Audio directly for maintenance and replacements. Introduction Thanks for purchasing the SUPREMEVISION FM wireless transmitter. This system is very reliable and easy to use. It is supported by a professional technical team who will ensure that, in the unlikely event that you strike any problems, you will be satisfied. Set the transmitter into any frequency freely ranged from 88.1 MHz to 107.9MHz. The transmitter is compatible with all FM receivers worldwide. Technical Specifications FM Wireless Transmitter Frequency 88.1MHz – 107.9MHz Output Power -10dbm Frequency space 50KHz Channel TBD Audio Sampling analog Current Draw DC9V 180mA Audio Frequency Response 50Hz~15KHz Mute audio mute when signal lost Transmittion Method FM Audio Input / Output Line Input, Digital Inputs (Coax. & Optical) Charge Power 9V power adapter Configurations 1.

Mode button (used to choose the audio source inputs, that is, coaxial input, fiber input or line input) 8. Memo button (used to memorize a new frequency) 9. ANT‐A (front antenna) 10. Set button 11. Enter button (used to confirm a new frequency) 12. ANT‐B (rear antenna) 13. DC/9V power input Jack 14. Antenna selection switch (used to choose the front or rear antenna) 15. Digital optical input jack 16. Digital coaxial input jack 17. Line input jack Programming Procedures Unlock by pressing the “LOCK” button till the lock icon disappears. The cursor defaults to the first digit. As you enter a digit for the new Frequency the cursor automatically moves to the right until you have entered all digits. Then press “Enter”. The decimal point is done automatically. If you make a mistake, you can start again or use the “UP”/ “Down” buttons to correct. Once you press “Enter”, the cursor will go away, and if you need to change, press “SET and start again. After inserting the wanted frequency, press “Enter” and then “Memory” to memorize the Frequency. Then the setting is done. “Mode” button: choose the inputs (digital coaxial input, digital fiber input or line input) The antenna selection switch: it has two depths. When you push it once, it goes deeper, and the system will use the front antenna. When you push it again, it is shallower, then the system chooses the rear antenna. Trouble Shooting Guide 1. When a STATIC INTERFERENCE occurs, please go through the following procedures to eliminate the problems. a. Sound level on TV or other audio source equipment may be too high. Check the equipment and adjust the sound level as needed. b. Check to see if any outside sources are using the same frequency as the transmitter. Either locate and remove the outside interference, or set the transmitter to a different channel to avoid that frequency. c. Check the antenna installation. Make sure the antenna selection is correct. Switch to the rear antenna if the front one doesn’t work, vice versa. Check the audio source cable. d. Make sure the transmitter mode is correct and the receiver channel number is correct. e. Check the sound by connecting it to a different transmitter. Listen from a receiver to see if the sound improves. f. Make sure the transmitter has power by checking the AC power cord: Is it plugged into a nearby outlet and into the transmitter? g. Make sure that the antenna is upright and not located near a power cord or any metal objects. h. If the problem continues, unplug the power cord for five minutes, then plug in again 2. When a NOISY SOUND occurs, please go through the following procedures to eliminate the problems. a. Make sure there are no major internal obstructions, such as metal support posts, between antenna and receiver. b. Make sure the antenna and receivers are installed so they are within the distance range. c. Make sure that the antenna is upright and not located near a power cord, audio cable, or any metal objects. d. Make sure the sound level on the TV or other audio source equipment connected to the transmitter is set to a reasonable, medium level. e. Try changing the transmitter to a different frequency to see if the sound quality improves. Some will be received better than others. It is suggested 300K frequency space to ensure the audio quality. f. Make sure no other wireless transmitters are using the same frequency at the facility. The user is encouraged to use our Tri‐band wireless receiver to do an auto‐scanning in the field before the installation to find out the frequencies being used. Avoid using the frequencies being used whenever you install a new transmitter. g. Check to see if any outside sources are using the same frequency as the transmitter. Either locate and remove the outside interference, or change the transmitter to a different frequency to avoid that frequency. 3. When there is NO SOUND, please go through the following procedures to eliminate the problems. a. Make sure the transmitter and the receiver frequency matches. b. Sound from the TV or other audio sources may be too low or muted. Check the equipment and increase the sound or un‐mute as needed. c. Make sure the transmitter mode and the audio input jacks match. Check the audio cable to the TV “OUTPUT” not “INPUT”. d. Check the sound from the TV or other audio sources by connecting it to a different transmitter. Listen from a receiver to see if the sound improves. e. Make sure the transmitter has power by checking the AC power cord: Is it plugged into a nearby outlet and into the transmitter? In case t…
