Product Description
The TUA-T550HD HD Radio tuner is a small hide-away box that can be connected to any of Alpine’s 2008 model Ai-NET head units to add HD Radio Technology as a source. With HD Radio receivers, consumers gain crystal clear music and talk from the more than 1,500 AM/FM radio stations nationwide that are currently broadcasting digitally. When the head unit is tuned to an HD Radio station, the head unit’s display will list artist, album and song information, if this selected station chooses to broadcast this metadata. As an Ai-NET pass-through source, the TUA-T550HD also allows for the addition of other Alpine Ai-NET audio sources, such as satellite radio, USB-based MP3 players and Bluetooth.Users may also enjoy HD Radio broadcasting’s unique multicasting benefits. FM multicasting allows consumers to listen to HD2 and HD3 multicast channels above and beyond the main station. This allows stations to expand their offerings to the public, without the fees associated with satellite radio.

I added the Alpine tua-550HD unit to my Alpine 9886 head unit, alpine kca-sc100 sirius satellite including steering wheel remote control and usb reader slash file player.
I felt when I added the HD unit, the sound reception took a dive. I listen to fm and am. The head unit would pull in long distance AM station at night (300+ miles away) and during the day would pull in weak station. To get this excellent reception of the head unit (no HD), I put a 1mh coil (LPF) between the DC power and an identical coil at the ignition power. I also add an Xterminator radio noise filter to the antenna terminal.
Once I added the HD unit the AM long distance reception took a dive and local station (AM or FM) were weaker. I think I’ll remove the unit at a later time since I like receiving distant AM station and I believe I get less multipath with just the head unit (no HD connected). The Alpine spec and most radio heads show identical FM AM specs so I didn’t expect a degradation in receiver performance.
This is my second HD radio. The first (a Dual 6420) would pull in AM stereo but constantly flip flop between digital and analog due to the coverage area. In my opinion, at this point HD radio is a flop. Satellite reception is far better, sound quality is better and lots of station (they never go out of coverage).
HD radio is ackin to when Stereo FM came about. It (Stereo FM) replace a noise free 70 mile reception signal with a 40 mile noisy, hissy, multipath Stereo signal. Now the broadcaster have taken us ever closer to 30 miles for HD reception and only added a few absurb side channels. When the broadcasters go full power digital maybe this will improve….
Btw, you must plug the Alpine Ianet cable into the “HD OUTPUT” if you want hear sound (the HD unit is the source). Other units (satellite etc) are daisy chained, out to in…to head unit in

Got one of these and it didn’t pick up many stations but sounded great. Thought the reception was normal from the HD reviews I’ve read. But then it would not turn on when I started the car — just dead. The regular tuner came on but had no antenna so it didn’t work. Turning off the car and turning it back on “fixed” it for a couple of days but then it started getting worse. Got the unit replaced.
The new unit picks up MANY more stations than the first and worked good for a couple of weeks. Now its starting to have dead audio occasionally when I turn on the car. The difference with this one is that the radio comes on — says ‘digital’ on the faceplate — but there is no audio until you turn off the car. That’s right, turn off the car, not the radio. Then it usually works when the car is turned back on.
This is very annoying. Alpine makes an amazing amplifier in the 9885 and it is awesome with my iPod connected directly to the radio. But the radio in the 9885 sucks, which is why I bought the HD radio, but the HD radio has its own kinds of problems.
Unless you really like putting up with problems, don’t get this tuner until the bugs are worked out.
