Introduction:

This device is the world’s first wireless true USB audio adapter/Sound card/FM transmitter with headphone output. It can modulate computer audio into stereo FM signal and transmit it wirelessly to audio equipment which has FM reception function, such as home theater, wireless earphone, DVD receiver, Car stereo, etc.

With the advanced feature of 7 Channels/selectable transmission frequencies, now you can easily avoid conflicting with local FM radio signals. By adopting digital PLL and RF amplifying techniques, this FM transmitter achieves good de-interference ability and ensures stable operation at a range up to 160 feet (50 meters). Enjoy your favorite music everywhere in your house.

With the USB headphone output feature, now you have the opportunity to experience the crystal clear USB audio with nearly 100dB SNR & dynamic range. Really a COOL product!

Easy to use:

1. Simply select a transmission frequency and plug the device into an USB port.

2. Play music with your computer, start the FM radio receiver and tune to the same frequency as the device selected and adjust the volume to a suitable level.

3. You can also directly plug a stereo headphone or speakers to the audio output jack to listen to high quality crystal clear USB audio, no AC hum, no static!

Notes:

1. Make sure you set the PC system volume via Control Panel to a HIGH level and increase the volume of the media play software (e.g. Windows Media Player, iTunes, WinAmp, etc.) to MED/HIGH level. Volume set too low will decrease the transmitter's power output.

2. The traditional sound card in your computer will not work while HFM7U is plugged in.

3. The audio cable also functions as an Antenna. Please place this cable properly to achieve good performance.

4. The actual transmission range depends on conditions in your home or office and the sensitivity of your FM receiver.

5. In case you need to change the transmission frequency to avoid conflicting with local FM radio signals, please set the 3-bit DIP switch according to the following table:

* No AC hum, no static for headphone/line output only.

** Depending on conditions in your home or office and the sensitivity of your FM receiver.

Buyer's feedback:

Hi
Really good upgrade to an already great product. Please could you keep me informed of any more upgrades/imroved products.
Cheers
Matt
P.s you should really get these in the shops all my mates want one.

Well, they are good units.

Personally I am using them in the car computers I am putting in.

I have tried the LineX boxes and were not too happy with them.

While those units did allow you to set different frequencies, I found they had too much noise.

Perhaps they just have a poor design, or it may be noise picked up over the USB cable before it gets to the box.

Either way, I quit using them.

Right now you units works well, it is small, simple to set up and delivers a clear, strong signal.

There are a lot of FM transmitters out there, but not too many USB sound card/transmitter solutions.

An area you might want to look into is the growing car computer culture.

Look at www.mp3car.com. Also check their forums about build and install info.

You might want to talk to them or other similar sites about selling your product.

There are many of folks who could use a simple and good working solution, but don;t know about you.

Personally, I just hunted eBay until I found yours ... it is a real gem that should get more exposure.

Again, you might want to spend some energy looking into the car computer area and mobile arena.

Most of them are early adopters, plus there are a significant number of them who have the position give you more exposure.

Good luck!
