Advantages of Digital Over Analog In Your Home Theater

In the increasingly digital age nowadays, you might feel compelled to leap into the middle of it. As HD becomes more popular, HDMI cables and optical outputs can become a dizzying array of jargon for certain people. If you’ve been wondering what the benefits of digital technology are, perhaps I’ll be able to clarify the benefits of digital here.


The early digital days weren’t all that bad when it came to connecting to your A/V equipment, in the case of basic stereo. The yellow video plug as well as two plugs for audio (red as well as white) were all you required. When the home theater systems turned into an aspiration it was a lot more wires to sort through.

Component cable or S-video was the next option, providing better clarity by dispersing color into distinct cables. But using a component video cable, you would need three wires only for pictures. If you want surround sound this would mean 5-7 extra wires to all audio channels and subwoofer cables. Whoa!

HDMI provides a high-def video signal that can be used to stream a full 1080p and all of your surround channels on one cable. In many cases, you can connect your DVR/Cable box or DVD/Blu-ray player. to your receiver or TV by using one cable (each) that dramatically reduces your cable clutter.

If you are using optical or coaxial cables for digital sound, there is one cable that is able to be used to carry two channels of sound and surround sound.

Improved Conversion (DAC)

In the process of using the sound from sources that are digital (CD/DVD/Blu-Ray), it will need to be converted to analog in order for those speakers that reproduce sound. In fact, even “digital speakers” must do this, they’re capable of performing this conversion on their own instead of relying upon another device.

All DACs (digital-analog conversions) are made equal. The accuracy with the way that digital signals are “translated” into usable sound waves is largely dependent on the device Set The Record Player.

If you’re using analog audio outputs of your player DVD, say this is the device that converts the sound utilized by the other components of your system. If it’s not performing an adequate job and the other components of your system could suffer, even with speakers and a top-quality receiver. The latest receivers are able to handle digital inputs by themselves, either via HDMI optical, HDMI, or coaxial. If you have a quality receiver the DAC is probably superior to the tvs.

Your HDTV box is able to send an electronic signal to your TV in turn, and if you connect your receiver to it via analog it’s causing the TV to translate the signal. If you use instead of a digital cable it’s just passing the sound signal (in digital) but without doing anything else to it. This is what allows the receiver’s superior DAC to process the signal U-turn Orbit Plus Review.

Be aware that this is the case for digital images, as well. If you’re not certain what the quality of the audio DAC or video is in your Blu-Ray or DVD player, but you do have a high-quality TV, HDMI can help solve the issue. The TV will be forced to convert the content and make your A/V experience better.

High Distortion

Electronic interfering (EMI) has been a major issue for analog connections since the beginning. Any number of electronic devices in your house can put off EMI while in operation, and while in most cases this is harmless it can have adverse effects on your A/V connections-particularly sound.

On a basic level, the audio signal is transmitted by the coaxial connectors a sequence of electrical frequency signals (that are transformed into sound waves by the speakers). Electromagnetic waves that travel through the air could penetrate through your wires and affect the sound signal that is going to and out of your receiver and cause distortion or static. High-end cables can be found that cover the wires inside an aluminum sheath to protect the wires from EMI. This is beneficial, however, shielded cables are considerably more costly than standard ones.

Because digital is all one and zeroes, digital is unaffected by EMI like analog audio signals do. So, by making use of HDMI (high-definition multimedia interface) cables as well as coaxial digital, or optical cables for audio, it is possible to eliminate this problem.


Digital offers a more practical way to experience higher-quality images and sound. I hope this helps explain the differences between analog and digital. If you have any questions, please leave a comment and I’ll try to provide the best answer I can!
