Hdmi audio extractor своими руками

Что такое адаптер HDMI ARC и когда лучше использовать HDMI Audio Extractor?

Если Вы счастливый обладатель устройства с HDMI ARC в наборе компонентов домашней аудио–видео системы, Вам может быть интересно, как получить максимальную выгоду от использования ARC при подключении всей техники. Оказывается, есть несколько электронных устройств, которые помогут решить эту задачу.

HDMI ARC

Будем полагать, что аббревиатура HDMI уже не нуждается в пояснениях. А что же такое HDMI ARC?

ARC (расшифровывается как Audio Return Channel) выполняет функцию передачи аудио сигнала обратно с телевизора на внешние устройства. ARC позволяет телевизору выводить цифровой звук на аудиоустройство и принимать цифровой звук с того же аудиоустройства через один-единственный кабель HDMI. ARC доступен только через порт HDMI (ARC) и только когда телевизор подключён к AV-ресиверу с поддержкой ARC.

Но что делать, когда ресивер не имеет поддержки системы обратного аудиоканала? Как использовать преимущества ARC?

Что такое адаптер HDMI ARC

Адаптер HDMI ARC поможет подключить устройства с ARC к другим системам, без поддержки ARC. Их часто называют аудио экстракторами HDMI или конвертерами, и они могут быть довольно удобными, потому что преобразуют один вход в несколько выходов с разным интерфейсом подключения. Адаптеры обычно преобразуют вход HDMI в 2 RCA, Jack 3.5 (разъем для наушников), S/PDIF: Toslink (Optical) или RCA (Coaxial).

Аудиоэкстракторы HDMI являются активными, это означает, что им требуется внешнее питание, обычно 5 В постоянного тока. Следует также помнить, что большинство этих адаптеров обычно имеют ручной переключатель для режима ARC.

Когда использовать адаптер HDMI ARC

Действительно ли нужен адаптер HDMI ARC? Основная причина использования HDMI ARC для аудио (через Toslink, RCA, Aux и т. д.) заключается в том, что HDMI может передавать управляющие команды, что невозможно при использовании других методов. Вторая причина в том, что это может быть единственный порт на телевизоре, способный передавать звук.

Например, если у вас есть звуковая панель, подключенная к вашему телевизору через HDMI, вы можете использовать пульт ДУ телевизора для управления звуком на звуковой панели, и наоборот. Это определенно намного удобнее, чем иметь два пульта дистанционного управления для каждого устройства.

Другой причиной использования экстрактора HDMI ARC является подключение устройств вывода, таких как консоли и медиаплееры, к ресиверам объемного звука 7.1, 5.1 или к более старым версиям объемного звука.

Перед покупкой обязательно изучите порты телевизора и звукового оборудования. Если все подключения происходят через один AV ресивер, проверьте порты на нем, возможно, там есть порты, которых нет у вашего телевизора. Большинство современных AV ресиверов имеют HDMI ARC, а также оптический и RCA интерфейсы.

Когда использовать HDMI Audio Extractor

Аудио экстрактор HDMI очень полезен в определенных ситуациях. Вероятно, наиболее распространенным является подключение более старой звуковой системы, не имеющей HDMI ARC, к источнику HDMI.

Вот некоторые распространенные сценарии:

• Звуковая панель (или динамики) поддерживает только Toslink (Optical)

Если ваша звуковая панель (или динамики) имеет только оптический порт, то нужен HDMI-аудио экстрактор с оптическим выходом . Такие адаптеры довольно распространены. В большинстве случаев оптический порт на адаптере будет помечен как SPDIF OUT. SPDIF — это стандарт передачи сигнала, с ним можно использовать и оптические кабели.

• У колонок (наушников) есть только вход Jack 3.5

Первым делом исследуйте заднюю или боковые панели телевизора на предмет наличия выходного порта Jack 3.5 мм. У большинства телевизоров будет хотя бы один. Если есть такой разъем, можно просто протянуть AUX кабель 3.5 мм от телевизора к колонкам. Если у вашего телевизора нет порта 3.5 мм, а есть только выход 2 RCA, то простым решением будет купить переходник или кабель 2 RCA в Jack 3.5. Такие кабели стоят недорого, это было бы самым простым и дешевым решением.

• Альтернативным способом, если телевизор не имеет даже разъемов RCA (в некоторых новых моделях отказались от этих портов), будет использование HDMI Audio Extractor с выходом Jack 3.5 мм.

Недостатки использования HDMI Audio Extractor

Прежде чем покупать аудио экстрактор HDMI, необходимо ознакомиться с минусами использования такого устройства.

• Хотя большинство аудио-экстракторов являются автоматическими (автоматически переключаются на HDMI ARC), в некоторых случаях переключение необходимо делать вручную;
• Рекомендуется приобрести адаптер HDMI ARC с несколькими портами, для большей универсальности. Например, с выходами 2 RCA, Toslink (оптический) и Jack 3.5 мм. Или, по крайней мере, Toslink и 3.5 мм, так как они наиболее распространены в колонках и звуковых системах;
• Если подключать ресивер через 2 RCA или Jack 3.5, то качество звука будет ограничено стереозвуком 2.0, т.к. конвертация 7.1 или 5.1 канального звука в стереозвук не происходит. Используйте Toslink, потому что он передает второй по качеству звук (HDMI — первый, RCA и 3.5 мм — самое низкое качество). Для наушников качество звука, вероятно, будет хорошим, но для объемного звука понадобится что-то другое;
• Другим недостатком является то, что для всех экстракторов HDMI требуется внешнее питание, через USB или другой источник питания;
• Помимо всего прочего, есть вероятность, что адаптер будет работать нестабильно, в т.ч. из-за некачественных кабелей или соединений.

Не со всех устройств удастся получить звук через порт HDMI с помощью аудиоэкстрактора. Некоторые производители оборудования кодируют передаваемый через HDMI контент с помощью системы защиты авторских прав (DRM — Digital Rights Management). Например, как следует из видео ниже, не получится вывести звук с PlayStation 5 на внешнее аудиоустройство, используя HDMI выход и аудио экстрактор HDMI.

В работоспособности конвертера для конкретной конфигурации оборудования нельзя заранее быть уверенным, однако, если найти экстрактор, который работает, то он будет работать долго.

Вывод:

В целом, аудио-экстрактор HDMI может отлично работать для подключения новых устройств HDMI к старым RCA или оптическим звуковым системам. Таким образом, вы можете продолжить использование старой электроники. Качество звука будет достаточно хорошим, но возможно, не самым лучшим.

Top 15 Best HDMI Audio Extractors in 2021 – Guide & Reviews

HDMI Audio extractors allow one to extract or ‘pull out’ audio signals from an HDMI source, which can be any equipment regardless of how it works and what it does. A lot of them also output the video signal as they separate the video signal from the audio signal available in the HDMI output. An HDMI audio extractor can always be connected to an audio deck or external speakers. The home theater system or any surround sound system can also take the signal from the HDMI audio extractor and play the sound with its purity. Those HDMI audio extractors that can extract both the video signal at 1080p and the audio in stereo or surround sound format are highly beneficial as the video output can be fed to a projector or a large LED screen and the stereo or the surround sound audio can be played on loudspeakers or the home theater system. Many other HDMI audio extractors, however, extract the audio signal only from the HDMI source. These can only be plugged into sound systems, which are either two-channel stereo or 5.1 channel surround sound systems.

Benefits and Uses of HDMI audio Extractors

The HDMI audio extractors are very useful and provide a lot of benefits. These are summed up below:

Better than ARC Audio Extractor

The HDMI Audio extractors are superior in performance to the ARC audio extractors. While many people confuse the two very easily, there is a gulf of a difference between them and in the audio Compatibility they provide. As far as the HDMI standard is concerned, there exists an optional feature, which is known as the Audio Return Channel (ARC). Many manufacturers of Television sets provide this particular standard in their equipment. In TV sets, it replaces the ‘headphone’ output or the optical SPDIF (Sony Philips Digital Interface) or the digital coaxial port. The use of the ARC has got limitations, however, as it does not work with all types of speakers. The reason why ARC is incorporated into the TV sets is to reduce the complexity of cabling between the TV set and the speakers or the Audio/Visual (AV) receivers. However, ARC might not be supported by certain older equipment that still gives high-quality sound but does not incorporate the ARC feature. The HDMI audio extractor output, however, can be given to any speakers which take a 2-channel stereo or a 5.1 surround sound input.

Connectivity to Blu Ray or Skybox

When using a source device such as the Skybox or BluRay player, it is always a good idea to use the HDMI Audio Extractor. If the listener wants to send the audio signal to the headphones, Soundbar, or the Audio/Visual system, it is always better to use this extractor instead of taking the sound from the Audio return channel (ARC) HDMI port on the TV set. The HDMI audio extractor can easily take the audio from any HDMI source. The extractor duplicates the audio and can send it out to any piece of equipment like the speakers, headphones, phono, AV sound system, or the Soundbar. Optical SPDIF can be used for this purpose. Once this is done, the video signal will travel to the Television set in a normal manner while the sound goes through the audio extractor, as described above. The ability of the HDMI audio extractor to pull out the around from any HDMI source is the greatest benefit provided by this extractor.

Direct from Apple TV 4k Box to Sound System

For those people who own an Apple TV 4K box, they can make very good use of their HDMI Audio extractor. Many of the current users of this TV box run a cable from the HD Television’s optical digital output to their sound system via an external Digital to Analog Converter (DAC). These people can directly take the audio output to the sound system without routing the signal through the TV set. This procedure is especially beneficial; for those people whose sound system is not a stereo system but a 5.1 surround sound system. This is the case because many TV sets are designed to convert the audio signal to a 2-channel stereo signal by default when they send an output over an optical digital connection. Thus, the people who want the 5.1 channel surround sound signal would not get the sound they want. By using an HDMI Audio extractor, the extractor will send out a 5.1 channel surround sound signal directly to the surround sound preamplifier.

Types of HDMI Audio Extractors

The HDMI Audio extractors are mainly divided into two types; those which output a video signal. These are described below:

HDMI Audio Extractor with Audio Only Output
