Guide Review - ZVOX Audio Z-Base 575 Low Profile Single-Cabinet Surround Sound System

All you have to do to get going with the Z-Base 575 is unbox it, plug in the power, connect an audio source, and turn it on. The total time, less than 10 minutes from box to surround sound.

The Z-Base 575 has two sets of analog RCA stereo inputs on the rear panel. It is important to note that the inputs on the Z-Base 575 are mixed inputs. In other words, both sets of inputs are always active. If you have two sources connected and they are both on, you will hear sound coming from both sources. It is suggested that you only have one source on at a time.

There are no controls provided on the front panel of the Z-Base 575. All controls are located on the remote control. There are several settings on the remote: Mute, Auto on/off, Volume, Phase Cue, Subwoofer level, and Treble control. Also, other than a blinking blue light on front the 575, there is no LED display to give you feedback on the degree of adjustments you make - you have to do it all by ear. The problem here is that although your ears are the best judge for listening, having a display reference would be helpful to enable to reset your listening preferences for a particular DVD or CD, such as the degree of Phase Cue or Subwoofer level.

However, all that being said, the real test is how the ZVOX 575 actually sounds. I found that the Z-Base 575 delivered both very good sound and was easily powerful enough for a small or medium size living room. Testing audio soundtracks from DVDs, the highs were not overly harsh, the mid-range was distinctive, and the bass response was deep, but not overly boomy. The surround sound imaging provided a wide front soundstage and lots of depth, but did not produce as accurate directional cues, or side/rear effects, as a true 5.1 channel system would be able to do.

In addition to providing good performance with DVDs, the ZVOX also does very well with music CDs, which full frequency range and depth. Vocals standout very well in most cases. In some instances the Phase Cue adjustment produces an unneeded "reverb" effect on vocals, but this can be easily remedied to your own preference by decreasing the Phase Cue effect slightly. Movies sound better with a wider Phase Cue effect, while music lends itself to a more restrained Phase Cue setting.

This system is not a replacement for a true multi-speaker system in a large room, but it is a great option for a basic no-frills surround system that can enhance your TV viewing, as well as providing a great way to listen to CDs and other music sources; it sounds great with movies or music. The Z-Base 575 can also be used as a bedroom, office, or secondary family room. system. However, some features that would be desirable additions would include more inputs and source switching.

If you are looking for a no-frills, but practical, way to get better sound out of your TV, or even to listen to music, without the hassle of a complete home theater system, the Z-Base 575 is a good value and definitely worth a critical listen.
