What to look for in HTIB
Home-theater-in-a-box or HTIB comes in many different configurations and features. Let our experts explain the specs that matter.

Power ratings |
|
Home-theater-in-a-box (HTIB) power ratings are
less stringent than component FTC ratings. Most use the more liberal Total Power
rating, but high power is important only if you're interested in playing music
or movies loudly. Then again, if loudness capability is a major concern, we
recommend moving up to a separate component system. |
|
| Surround sounds |
|
Dolby Digital, Dolby Pro-Logic II and DTS are the most
common HTIB surround decoders. While DTS is an alternative and, some believe, better-sounding 5.1-channel surround format than Dolby, DTS-encoded DVDs and CDs are less common compared to the latter. Dolby Pro-Logic II and Logic 7 produce a more natural surround effect from older Pro-Logic-encoded DVDs, videotapes, and stereo CDs than conventional DSP (digital signal processing) modes. So-called virtual surround can offer surround sound from the front speakers. |

| Other features |
|
Onscreen displays (OSDs) ease setup and
navigation chores. Programmable remote controls can control TVs and other A/V
components. AM/FM tuners are standard on just about every HTIB. |
|
| Audio connectivity |
|
More connectivity options are desirable; one
or two audio/video connections are fine but limit HTIBs to standalone systems.
HTIBs with 5.1 analog inputs allow hookup of a separate Super Audio CD (SACD) or
DVD-Audio player. If you have additional sources--VCRs, a satellite, games, or
video cameras--make sure that the HTIB has enough inputs. Phono inputs are
important if you'd like to hook up your turntable to your HTIB--don't assume
they're there. Digital audio inputs and outputs are required if you use a
digital cable/satellite box or CD/digital recorder. There are two types of
digital connectors: coaxial, which looks like a standard RCA connector, and
optical, a square-shaped optical jack. Speaker wire connectors range from the
less desirable spring-clip/clamping types to the more secure binding
posts. |

| 5.1-speaker system |
|
HTIBs always include a minimum of five
speakers and a subwoofer, but the quality and sizes of those speakers run the
gamut. The smallest satellite speakers are 4 inches tall, and the largest models
run to 10 to 12 inches; the larger models tend to be the better-sounding
designs, but some microsatellites can sound quite nice. Low-end satellites are
one-way, single-driver units, whereas mid- to high-priced HTIBs feature two-way
woofer and tweeter designs. Most satellites are magnetically shielded and can be
placed in close proximity to a TV screen. Most satellite speakers are equipped
with wall brackets or provisions for wall-mounting.
Most HTIB subwoofers are powered by the receiver's amplifier, although some
systems feature "powered" subwoofers with their own internal amps. The latter
approach usually sounds better and produces a deeper, more defined bass
response. Some HTIB subwoofers also incorporate amplifier channels for the
satellite channels, as well. |

DVD player |
|
HTIBs with integral DVD players are the norm.
All HTIB DVD players play DVDs, VCDs and CDs. Some of the latest models also handle MP3, SACD, DVD-Audio, DivX, WMA and JPEG formats. Both single- and multidisc changer models are available. The
changers, typically holding five discs, employ elevator- or carousel-style
mechanisms. Elevator-equipped HTIBs tend to be smaller and more compact; the
carousel models are larger and can be 17 inches wide and 15 to 18 inches deep.
Higher-end HTIBs typically offer separate component-style receivers and DVD
players. Some budget HTIBs omit the DVD player entirely and may be useful to
buyers who use only cable, satellite, or a VCR as video sources. |

| Video connectivity |
|
Your HTIB video output connectivity needs are
dictated by the connections on your TV. Possibilities include composite, the
most basic video connectivity option; all TVs and HTIBs have at least one set of
composite connections. S-Video connections are also common and offer better
resolution and fewer artifacts. Component outputs, in the form of three RCA
jacks (Y, Pb, Pr or Y, Cb, Cr), produce even sharper images and more accurate
color reproduction. Some of the latest models also come with HDMI/DVI digitial connectivity, but only newer TVs are likely to have these digital inputs. |

Warranty |
|
One year on parts and labor is standard, but
some manufacturers offer only 90 days. HTIBs are complicated devices, so
extended warranties, if offered at reasonable cost, are worth
considering. |
