Only at Best BuyThis Insignia™ NS-HZ308 RF modulator converts line-level composite video/analog stereo audio signals to RF (coaxial), so you can easily connect your A/V devices to a TV without an A/V input jack.
I use the RF Modulator for my Karaoke business by outputting the singer's screen to all the TVs in the venue. I had previously used the venue owner's modulator but after some time it became a hassle to disconnect-move-reconnect every night plus setting it as it was during pack-up. I purchased my own to save time. One difference I noticed between this one and the venue owner's more expensive version is that it puts out a much stronger signal. I have to disconnect the venue's network of TVs from the local cable provider to let the modulator's signal get through. With this modulator, it actually overpowers the local cable on the closest TV without having to disconnect. The main upside is that once I disconnect the local cable, the signal is clear on all the TVs, even those on the furthest side of the venue. Previously they were a but fuzzy. This is totally worth the price. The only downside is that it does not have an LED to indicate when it is on or when it has a signal. If I could change one thing about it, that would be it.
