Multifunctional Home Theater Receiver is a major component stereos. In one case AV (audio-visual) decoder device combined functions of the amplifier and switch. Through him, you are connecting with the management of the entire set of home audio and video equipment.
To make maximum use of all the possibilities the cinema after the purchase, pay attention to the types of equipment, connectors, number of channels, power, audio decoders and the ability to connect to mobile devices.
Manufacturers offer two basic types of such devices - the usual AV or combo DVD. Budget home theater kits are usually supplied with the models of the first species. Combined versions are more common within large home theaters. Structurally, they are combined in one housing the DVD player and AV receiver. Benefits of such combinations:
- reduced number of wires;
- ease of connection;
- equipment management convenience.
input options
As another technique, the receiver has a front panel with controls and all connectors are usually located on the back side. Their abundance may initially be difficult, but the connection method is intuitive. With instruction can accurately determine the function of each connector. Among them, there are compounds such embodiments:
- multiple HDMI inputs, which provide a comprehensive signal transmission of audio video and control commands;
- component audio and video connectors (RCA) connector for three color-coded, are not inferior to the first signal quality;
- a similar input on two tulip red and white;
- under the same input one connector yellow;
- input to the fiber optic connection;
- SCART connector to transmit an analog signal;
- one-component input for S-Video Broadcast signal.
In the selection of AV amplifier count all the audio and video devices to select the unit with the appropriate number of connectors.
It is important to pay attention to the HDMI contacts. Ideally, they should be enough to connect:
- DVD player, it Bly Ray analogue;
- TV receiver, a multimedia projector;
- game boxes.
Number of audio inputs depends on the configuration of the speaker system, which can support multiple channels.
Multi-channel and power
Modern acoustic multi-channel system. From this characteristic it depends on the quality stereo sound, by which an effect of presence. It denoted by a combination of numbers, for example, in the embodiment of minimum 5 or 5.1. Number 5 indicates the number of speakers, and 1 - subwoofers.
The AV system is integrated power amplifiers. Usually, the more of them the better. But also keep in mind that excessive or insufficient power can badly affect the perception of acoustics. Pick up power based on floor space and features of the connected equipment.
For a room area of 20 squares configuration will suffice 5.1 with about 100 watts each column. For a more spacious premises and work together with players Bly Ray 5.1 some models will not be enough, it will take at least seven speakers (7.1). To equip a large room under the cinema is necessary to take a multi-channel model that will provide surround sound.
sound decoders
AV amplifier must support all existing standards. On this depends the quality of the acoustic effect of surround sound. Otherwise, playback and sound perception will be worse than the original version, and the signal correction decoders require the use of external devices.
Minimum requirement - Support for the two main standards DTS and Dolby Digital, which are typically used when recording video.
additional Features
Manufacturers AV amplifiers built into the possibility of equipment to maintain connectivity with mobile devices that can work with the home theater. These include:
- computers, laptops;
- tablets;
- smartphones;
- photo and video cameras.
There are several types of standards and compounds that provide content sharing between the AV receiver and the listed equipment.
| Dlna | Set of standards to support wired and wireless transfer of content |
| Wi-Fi | The wireless data transmission, installed on most mobile devices |
| Ethernet | Standards that provide packet data coverage for computer networks |
| Internet radio | Technology packet of audio data for broadcast publishing |
| AirPlay | Wireless streaming of media content on the Apple iPhone and iPad |
| Smartphone control | App to communicate with operating systems iOS and Android |
