Vizio VO47L LCD HDTV Review
The VO47L manages something of a tightrope act; keeping the price down, while still producing decent quality.
|We found the audio quality of the Vizio VO47L to be adequate, although we have seen slightly better from other TVs. The surround sound feature actually produced worse quality, so we recommend you leave that off.|
The Vizio VO47L's audio quality is nothing to write home about, but it isn't terrible either. Voices can be discerned easily, even with a lot of background noise in the scene, and we detected no major problems that will throw people off. If you're used to the standard sound quality that a TV provides the Vizio VO47L will neither impress you nor disappoint you.
The Vizio VO47L offers a simulated surround sound system, as is typical of most TVs nowadays. Unfortunately we found that it did not do much to actually simulate surround sound. The major effect seems to be to turn up the volume on background sounds, so you can hear that footstep coming a bit better, but at the cost of foreground sounds being muted, so you'll be straining to hear the dialogue. Compared to even an inexpensive surround sound system there's no comparison. We recommend that if you want surround sound to go buy a set of speakers, even a cheap set, and otherwise leave the simulated surround sound off.
The Vizio VO47L's speakers measured 87.6 decibels in our test of loudness. This is quite loud enough that no one should have any trouble hearing the TV, in fact we believe that anyone who turns it up this loud will likely be deafened in short order. We made this measurement using a sound pressure meter from five feet away with the volume at maximum and using pink noise as our reference sound.
