About the Sony DSX-A40UI
Go digital without going broke
Go digital without going broke
Ditching the discs and going digital doesn't have to break the bank. Sony's DSX-A40UI digital media receiver offers an impressive list of features for its price range, along with plenty of connections for all your devices.
Everything you need
Bells and whistles are nice, but you don't necessarily need them to go all-digital in your car. The DSX-A40UI has all the basics covered, starting with a sleek-looking removable faceplate that also offers the functionality you need to enjoy your digital music library.
A handy USB port gives you lots of options for enjoying your digital music. Plug in a flash drive that you've loaded up with music, or connect your iPod®, iPhone®, or Android™ to listen to music and charge the device. You'll be able to use the receiver's controls to search through your music, and Sony's Quick-BrowZer® feature makes it easy to find music by artist, album, genre, song or playlist. You can also connect a satellite radio tuner or a portable music player to the front auxiliary input.
Adjust and expand
The built-in amp ensures that your music will come through loud and clear, even when you're really cranking it up. If you're the kind of person who likes to fiddle with the settings to suit your exact tastes, you'll be surprised at how much adjustability you get with the DSX-A40UI's 3-band equalizer. If you're thinking about adding an amplifier in the future, you'll find a set of 2-volt preamp outputs on the back panel.
This receiver offers a simple control panel with USB and auxiliary inputs.
Whether you're listening to digital music or your favorite AM/FM radio station, you'll be able to see what's playing on the single-line LCD display, which shows you track info, station ID and a clock. The faceplate's red button illumination adds a touch of style. You also get a handy remote control that lets your passengers play DJ while you drive.
Want to keep your car's steering wheel audio controls?
In most cars, you'll need an adapter to retain those controls with this car stereo. Connect a few wires, then program the adapter for your particular car and radio, and you'll retain the convenience of your steering wheel controls. You'll see the adapters that work with your vehicle when you add this receiver to your cart.
