2ACGI-TX900AT900MHz large area transmitter

1 Model No.: ARG-900AT Introduction: Thanks for purchasing the ARG 900MHz wireless entertainment 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 experience any problem, we will work with you to solve it. Set the transmitter to any frequency within the range of 902.050MHz to 927.950MHz. Technical Specifications ARG-900AT 900MHz Wireless Transmitter Frequency 902.050MHz - 927.950MHz Frequency space 50KHz Channel 519 Audio Sampling analog Current Draw DC9V 200mA Audio Frequency Response 50Hz~15KHz Mute audio mute when signal lost Concurrent Systems 20 Transmission Method FM Audio Input / Output Line Input, Digital Inputs (Coax. & Optical) Power 9V Power Adapter LCD Display 2 1. Volume (adjustable from 0 to 15, the volume icon flashes when there is no audio input or the input source mode selection is incorrect) 2. Frequency (see frequency setup details in programming procedures) 3. Memory icon (after inputting the frequency, the user must press the “Memory” to save the frequency, and you can see this icon flashing once on the display) 4. Lock icon (make sure to lock and unlock as per the instructions during operation) 5. Digital fiber input icon (make sure to change the mode to this icon when the audio source is connected to the digital fiber input jack) 6. Digital coaxial input icon (make sure to change the mode to this icon when the audio source is connected to the digital coaxial input jack) 7. Line input icon (make sure to change the mode to this icon when the audio source is connected to the line input jacks) Programming Procedures Transmitter volume setup: Use the “UP”/”DOWN” button to adjust the volume level (0-15) under lock status. Frequency setup: Unlock the transmitter by pressing the “LOCK” button till the lock icon disappears. Since all Frequencies start with „9‟, the cursor defaults to the second digit. As you enter a digit for the new Frequency the cursor automatically moves to the right until you have entered all 5 digits after the „9‟. Then press “Enter”. The last digit is always zero, so it does not need to be changed. The decimal point is placed 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 desired frequency, press “Enter” and then “Memory” to save the selected Frequency. Then the setting is done. (Note: Only the frequencies between 902.050MHz to 927.950MHz are allowed to be entered) Input source selection: use “Mode” button to choose the inputs (digital coaxial input, digital fiber input or line input) under lock status. Antenna selection: The antenna selection switch 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 uses the rear antenna. Trouble Shooting Guide 1. When there is a STATIC INTERFERENCE , please follow the procedures below: a. Sound level on TV or other audio source equipment may be too high. Check the equipment and adjust the sound level as needed. 3 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, or 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. 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 problem: 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. A 300K frequency space is suggested 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 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. If there is NO SOUND, please go through the following procedures: a. Make sure the transmitter and the receiver frequencies match. 4 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. Check to see if the volume icon on the LCD display is flashing. Make sure the transmitter mode and the audio input jacks match. d. Make sure the audio cable is in the TV “OUTPUT” not the TV “INPUT”. e. 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 improv…
