Penjelasan mengenai Spec.


Digital Optical ( for Audio )



RGB ( Red, Green and Blue ) can use for input YPbPr Video.


Jack to Jack ( for single input Audio )

















Phono to Phono (for Video)
















Jack to phono
Phono ( red and white) for L and R to single L/R (phono)













I am not going to recommend an all in one box, I recommend that you get separate components, and that way tailor a system for your needs/wants.
To better equip you for this task, here are the meanings to some of the more popular technologies out right now:

1) Dolby Digital-
Dolby digital was originally created for VHS; it’s a superior stereo sound. It is also
Referred to as Dolby digital 2.0 /2.1

2) Dolby Digital 5.1 –
This is the current surround sound standard. The 5 (in 5.1) stands for 5 full range
Speakers Left Front, right front, left rear, right rear, and center. The .1 stands for a
Subwoofer, or a speaker for low lever frequencies (1hz – 220hz)

3) DTS –
This is a rival format to Dolby digital 5.1; the main difference is that DTS has a higher
Bit rate, and therefore takes up more space on a disc (physically). Because of the
Higher bit rate, it sounds a little better. The good part is that most audio video
Receivers can do both DD 5.1 and DTS.

4) THX –
If you are going to drop some money, then get a THX certified receiver. All THX
means is that after your signal (sound) has been converted from digital to analog (so
we can hear it) there is some further processing. This certification provides a high
standard, and I have yet to hear a THX receiver that does not sound amazing. THX is
brought to you by our friends at Lucas film (the people who made star wars)

5) DTS 6.1 / Dolby Digital 6.1 matrix –
There is now a 6th channel (which is becoming the new standard ?) this is a rear
center channel. This gives a more accurate 3-D sound. A 6.1 matrix is when instead
of having a 6th channel hook up on the back of a receiver, its encoded into the two
back channels. I have never seen this hooked up

6) DTS Discrete 6.1-
Same as #5 but this time the 6th channel has its own speaker jack in the receiver, this
provides a much cleaner sound.

7) DTS, Dolby 7.1 -
Now you have seven speakers, center, two in the front, two in the rear, and two on the
side. It is only matrix right now, I have not seen a discrete.


Do some research into Axiom, Mirage, Paradigm, Klipsch, Polk, Koss, Cambridge Soundworks

What the different between digital coaxial and digital optical

Optical transmits audio information in the form of a beam of light, digital coax uses an electrical impulse. There are differences, and you'll hear arguements for and against both, but they are so close you won't tell the difference.

Make sure you have the same connection on your source and your receiver. If you have both, I prefer optical, but get a cable that's long enough to ensure there are no sharp turns in it. (Light doesn't make sharp turns)

SPDIF

SPDIF:
A common use for the S/PDIF interface is to carry compressed digital audio as defined by the standard IEC 61937. This mode is used to connect the output of a DVD player to a home theater receiver that supports Dolby Digital or DTS surround sound. Another common use is to carry uncompressed digital audio from a CD player to a receiver. This specification also allows for the coupling of personal computer digital sound (if equipped) via optical or coax to Dolby or DTS capable receivers.

1) RGB mean Red,Green and Blue.

2) HDMI mean High Defenition Media Interface

3) YPbPr mean Improvement fron RGB ( sent more colour signal to sharp picture)
