Editors' note: We found the Insignia NS-DXA1 and the Zenith DTT900 have virtually identical design, features, and performance; therefore, their reviews are the same.
The FCC has pushed back the DTV transition several times already, but it looks as if it will shut off over-the-air analog TV signals on February 17, 2009. That means owners of analog TV will need to pony up for a DTV converter box if they want to continue getting their free over-the-air TV (read our Quick Guide to the DTV transition to find out if you'll be affected). Luckily, it shouldn't cost you too much, as anyone affected can apply for a $40 DTV converter box coupon from the U.S. government.
The Insignia NS-DXA1 is one of the DTV boxes that shoppers can buy with the coupon, and it's worth a serious look. On arguably the most important features--reception and video quality--the NS-DXA1 performs strongly, outperforming the other boxes we've looked at so far. We did have some nitpicks: the remote is too small, audio quality is subpar, and we would have liked a full-scale EPG (onscreen electronic program guide). However, these caveats are for the most part overshadowed the NS-DXA1's other strengths and make it a good choice for your government-subsidized coupon. Our biggest hesitation is price--with a list price of $60, you'll have to kick in $20 of real money in addition to the coupon. That's compared with Echostar's upcoming DTV converter box, which--with its $40 retail price--will effectively be free. If you're itching to start watching digital over-the-air TV right away, the NS-DXA1 is one of the better options currently available, but buyers would be wise to wait until more boxes are on the market.
The Insignia NS-DXA1's design is simple, but we liked it. The main chassis is made of black metal, accented by a plastic faceplate that has the popular glossy black look to it. The metal body makes it feel more like a more expensive item, especially considering that most other DTV boxes are made of plastic. In the center of the faceplate is a small LED light that glows blue when the device is on and red when it's off. To the right of the light are channel up and down button, and further right is the power button. Overall, the NS-DXA1is one of the more attractive boxes available.
The first thing you'll notice about the NS-DXA1's included remote control is that it's small. That's unfortunate, because we actually liked the button layout on the remote, but it's not a good option for older buyers with less-than-perfect eyesight. (If you're looking for a DTV box with large remote buttons, check out the RCA DTA800.) If you can get past the small size, it's actually pretty decent, with individual button rockers for volume and channel up/down, and a large directional pad up top. We liked the inclusion of a variety of buttons, such as a handy signal strength checker, the zoom button, and closed-captioning. We also liked how the remote handled digital substations--if you hit "4" on the remote, a menu pops up on the screen allowing you to choose which channel (4.1, 4.2, 4.4, 41.1, for example) you'd like to watch. Also note that it is capable of controlling a TV, although that capability is limited to turning it on and off.
The NS-DXA1 includes a very basic program. Hitting the guide button brings up the "Simple Guide," which shows what's currently on a channel and what will be on next. The EPGs on more advanced products such as TiVo or even standard digital cable boxes usually show more information, such as program data for several hours in the future for several channels at a time. It's definitely better than nothing--which may be what many buyers of this box are used to--but there's definitely room for improvement.
Aspect ratio is handled well on the NS-DXA1. This is an important feature because the NS-DXA1 will most commonly be used with older, analog TVs with a standard 4:3 aspect ratio, but an increasing amount of digital TV is presented in wide-screen (16:9). The NS-DXA1 has four options, which you can cycle through with the "Zoom" button on the remote.
Set by program: Presumably sets the aspect ratio as the content maker requests.
Letterbox: Keeps wide-screen programs in their original form, but adds black bars on both the top and bottom of the picture.
Cropped: Maintains the proper aspect ratio, but literally crops out of the extreme right and left sides of the picture.
Squeeze: Doesn't remove any part of the picture, but distorts the aspect ratio, making people look tall and skinny.
