Product Operation Description of SP1551 This product is a 900MHz transmitter, which is part of a stereo wireless Speaker system (via Speaker) for audio usage. They would be operated with its associated receiver (Speaker), with one AC/DC adaptor TEAD-28-120150U (Input: 120VAC/60Hz/3W; Output: 12VDC, 150mA). The main function of SP1551 are demodulating the audio signal, transmit RF signal to associated receiver. The operating frequency of SP1551 is 912.0MHz, 912.5MHz and 913.0MHz; the transmitting frequency can be selected by pushing the channel-selective button, which was equipped at the side of SP1551 body. SP1551 consist of two indicating lights, one is POWER LED that will be in red color when AC adapter is plugged in, the other is SIGNAL LED that will be red color when audio signal is input. There is one audio cord on the rear of the transmitter that can be connected to audio output jack of TV, Monitor, VCR, Radio recorder, CD/MP3/VCD/DVD players or to headphone/earphone jack with the connector provided, the DC jack on the rear is used for DC power connection.
