User and Installation Guide 2 4 GHz RangeBooster Transmitter Amphony Userand instalation Gude Amphony Unpacking Check that this package contains One 2 4 GHz RangeBooster transmitter one AC adapter How to use the RangeBooster transmitter The RangeBooster transmitter can be used in situations where sufficient coverage cannot be achieved by the primary transmitter and works as a repeater in conjunction with the primary transmitter In the example below a pair of 2 4 GHz Digital Wireless Headphones is operated such that there are 4 walls between the transmitter and headphones In this case the signal reaching the headphones may be too weak for proper reception By adding a RangeBooster transmitter as shown in the example coverage can be improved for the area in which the signal of the primary transmitter was too weak without the RangeBooster transmitter or in cases where there may be interference from other 2 4 GHz devices Since the audio signal is transmitted digitally to the RangeBooster transmitter no audio degradation will occur Primary Primary transmitter transmitter Data cable connection FN N A A RangeBooster Example 1 Headphones Example 2 Headphones without RangeBooster using RangeBooster reception is improved The RangeBooster transmitter will reproduce the signal from the primary transmitter and create a secondary coverage area The RangeBooster transmitter will receive a data s
3. de Data cable RCA connector RCA connector lt q fa rE 50 to 75 Ohms shielded coaxial cable Locating the RangeBooster transmitter The location of the RangeBooster transmitter should be chosen such that e the number of walls and obstacles between the RangeBooster transmitter and the headphones receiver is minimized anywhere in the desired coverage area to improve reception the cable length of the data cable will be as short as possible preferably less than 30 to 50 ft to minimize data signal degradation and e there is sufficient RF signal attenuation between the primary transmitter and the RangeBooster transmitter no line of sight to minimize RF signal competition between both transmitters Elevation as well as the presence of reflecting walls will influence the coverage area of the RangeBooster transmitter It is suggested to experiment in order to find the best location for the RangeBooster transmitter Page 2 User and Installation Guide Amphony Connecting the RangeBooster transmitter Install the data cable such that the cable length is minimized Optimum performance will be achieved if the cable length is 30 ft or less Connect the RangeBooster transmitter power input with the supplied AC adapter Connect the data cable with the data input at the RangeBooster transmitter and the data output of the primary transmitter The primary transmitter should be connected as described in the user manual RangeBoos
