[QUOTE]This FM modulator makes it easy to add "Home Theater" sound to your mobile video system. It modulates line level audio (stereo) from a VCR, DVD, automotive TV tuner or any audio source, to an FM frequency so you can receive the signal on your factory radio sound system.[QUOTE]
The fm modulator sold at Parts Express has an RCA outputs(right & left channel), an input and output connector for the antenna, a pigtail for a +12volt and ground connection.
There are 2 switchable frequencies: fm1=88.7mhz, fm2=89.1mhz.
Stand alone rf modulators with rca input were what came with most changers in the mid to late 80's but were very scarce until in car video became popular. Any local car audio shop or accessory shop dealing with Audiovox mobile video will stock the modulator and should sell it for at least half of the parts express price. The reason it is used in mobile video is becuase the majority people who are buying $2500+ video systems want to keep the factory head unit in thier cars. jas
