Why do receivers have video inputs




















Audio inputs AV receiver can accept audio from various sources such as HDMI, digital optical, coaxial and analogue stereo inputs. If you want to listen to vinyl records, then the AV receiver should have a phono input. Additionally, many AV receivers may also feature 3. Multi-channel speaker outputs The number of multi-channel speaker outputs also plays an important role while looking for an AV receiver.

Currently, most AV receivers are built for 5. For a basic home theatre setup, you must have a minimum of 5 speakers and 1 subwoofer 5. For a fuller experience, you could opt for a 7. Often with a 7. This is also the basis for multi-room connectivity in AV receiver from many manufacturers.

Why do you need an AV receiver? In many ways, the AV receiver is the brain or the central processing unit of a home theatre system. Without it, you would have rather limited options when it comes to entertainment options in your home theatre setup. Without an AV receiver, the home cinema experience would be lacklustre and boring. The Bad: No surround sound - unless you use your receiver with that wonderful "Disco Hall" sound processing algorythm.

The Ugly: That wonderful "Disco Hall" sound processing algorythm. Buy totally awesome and cool Stereo Cables! Digital Audio connections, Coax on left, Toslink Optical on the right. Digital Coax uses a single orange color coded "RCA" connection. These support "AC3" Dolby Digital 5.

The Good: Easy, one cable connection for 5. Sounds pretty great depending on equipment Pretty much completly cable agnostic, provided the cable is working properly. The Bad: Optical cables have length restrictions unless they are "special" such as glass fiber. They never used to put enough of these connections on a receiver! Listen to a great recording on one of these formats on a nice system and then listen without.

Maybe not ugly, but quite surely something is "lacking". For 6. Surround sound analog connections on computer sound cards use "mini" 3. Sounds as good as anything if the Source and Receiver are of rather nice quality. The Bad:. Problems with "Bass Management" subwoofer levels are common. Most receivers don't "do" bass management on the multichannel analog audio inputs.

The Source should handle this in any case, so the receiver does not have to convert the signal to digital for processing and then back again for amplification. Even many with high resolution audio format support. In fact, some Blu Ray and HD DVD players offer only limited support, even though they are the only devices capable at this time of decoding these Audio formats.

Receivers and Processors have been announced and should start appearing in the summer of '07, but there are real reasons that the players can be a better choice for decoding. The AVS forum thread " 5. The Problem? Some of us don't care about 7. Got a headache yet? If you Want to use the Receiver as the decoder, you will need a Receiver capable of decoding the formats and both receiver and player must support HDMI 1.

This will use the "DAC's" on the Receiver to convert the digital audio into analog, so if you feel you have better quality DACs on the Receiver, this is best. If you have no choice, like with the PS3 which has no multi channel outputs, you must use this method. Analog 5. Let the Receiver do the decoding and digital to analog conversion and connect the multichannel outputs of the receiver to the multi channel ins on the receiver.

Check with your provider! S-Video and Composite video do not support HD. HD is either p, i or p. Does it have a digital audio input? Make sure to set up the Receiver to use the digital audio from the input you connect to.

It is a good idea to also run analog audio cables to the receiver as well, in case some stations do not put out a digital signal, or the digital connection fails. For the new, high resolution audio formats, please see the audio connections section. Well, since most receivers will do a worse job of this than your HDTV, it's really up to you.

Do you want convenience or signal quality. People tend to think that anything will do a certain job as well as anything else. Well, hold on there, sparky. Just because a Receiver can "upconvert" one type of video to another does not mean at all , that it can do it as well as your TV can or some expensive video scaler can! It may be convenient, but it is very often similar to junk food. Of course, many TV's stink at this too. If that is the case, why not? What we think we know about speaker cables and what the debates are about them.

Speaker Cables are probably the topic most over-debated topic in the Audio Kingdom So why would we stick our necks out inviting "flames" by both the true believers and skeptics? Uh, cause we're sick of people asking maybe? Wastes power - excess resistance is converted to heat not very green of you. Shorter wires can get by with less. Capacitance is not a factor normally at normal distances with most equipment. Capacitance is debated by some, but generally because of confusion about analog line level capacitance issues 3 Inductance?

Inductance can possibly effect the signal in a non-linear fashion in the audio frequency spectrum effecting the high frequency response with some combinations of cable, amp and speakers. Actual Audibility is questionable. A better dielectric can also effect capacitance and inductance values. While the dielectric should not have an audible effect in the audible spectrum itself, it can have an effect at very high frequencies well above signal frequencies and can have an effect on longevity of cables maintaining ideal characteristics due to oxidation and dielectric degradation over time.

However, there are some practical reasons to route both your video and audio signals through a home theater receiver. Here are some of those reasons. One reason to route audio and video through a home theater receiver is to cut down on cable clutter. HDMI carries audio and video signals. Using a single cable, you can connect the HDMI cable from your source component through your receiver for both audio and video using the one HDMI cable.

HDMI provides the desired access to both audio and video signals, and it reduces cable clutter between the source device, the receiver, and the TV. Instead of connecting a video cable from the source to the TV or video projector as well as a separate audio cable to the home theater receiver, all you need is one HDMI connection between the receiver and the TV or video projector.

In a specific setup, it can be more convenient to send the video signal through the home theater receiver, as the receiver can control the source switching for audio and video. In other words, instead of switching the TV to the proper video input that your video source component is connected to, and then also switching the receiver to the proper audio input, you can do it in one step if both video and audio can go through the home theater receiver.

If you have a home theater receiver with built-in video processing and upscaling for lower resolution analog video signals, routing your video sources through the receiver can provide some advantages.

The processing and scaling features of many home theater receivers may provide a cleaner video signal to the TV than if you connected an analog video source directly to the TV. If you own a 3D TV or video projector , many home theater receivers manufactured beginning in late going forward are 3D compatible. If your home theater complies with that standard, you can route 3D video and audio signals via a single HDMI cable through your receiver to a 3D TV or 3D video projector.

On the other hand, if your home theater receiver doesn't provide a 3D pass-through, connect the video signal from your 3D source such as a 3D Blu-ray Disc player to your TV or video projector.

You will then also make a separate audio connection to your non-3D compliant home theater receiver. Another thing to take into consideration is the 4K resolution video. In mid, HDMI version 1. The added introduction of HDMI version 2. But it didn't stop there. With HDMI ver 1. However, for those that purchased home theater receivers between and , there are some compatibility variations.

Just keep in mind that making a separate video and audio connections may also affect what audio formats your home theater receiver will have access to. However, unlike 3D, even if your home theater receiver is not compatible with all aspects of the latest 4K Ultra HD specifications, it will pass-through those aspects that it is compatible with, so users will still see some benefit if you still want to connect your 4K video sources to a home theater receiver that is equipped with HDMI ver1.

My suggestion is to decide how you want to organize the audio and video signal flow in your home theater setup and, if needed, purchase a home theater receiver that best fits your preferences in that regard. Monday — Friday, 8am — 5pm Showroom by Appointment.

Convenience First off, it can be more convenient to send the video signal through your receiver, as a receiver can control all the source switching for both audio and video.
