Active speaker setups (without using an A/V receiver) An AVR can decode the compressed surrounding sound or uncompressed PCM output from your DVDs, CD players, personal computers, gaming systems, and DAT recorders.įor these projectors, you can use the following setups. Only the two-in-one audio-visual HDMI cable and the TOSLINK protocol use optical cables to transmit high-quality digital sound streams. Optical or TOSLINK: There have been optical cables like TOSLINK before HDMI. Also, speakers’ S/PDIF connections are not standard since analog sound principles use electrical current rather than binary code to inform speaker design. You should know that, like RCA or a 3.5mm jack, S/PDIF can function as either an output or input connection type. Hence, if your projector has S/PDIF compatibility, you’re in luck since the sound you receive will be of the greatest quality. S/PDIF adapters convert analog audio to digital and then use a coaxial cable to deliver the digital signal. It’s also important to remember that some projectors may only have RCA connections, so you’ll want to double-check before making a purchase. The difference in their real structure makes one superior to the other under certain circumstances. These cables have split signal features that produce stereo sound. However, the 3.5mm jack and the RCA cable both transmit an analog signal and are susceptible to the same amount of outside interference. Remember that the 3.5mm jack is used for analog audio transmission and reception.Ĭomposite or Component Audio/RCA connection types: RCA connectors are a step up from 3.5mm jacks for inputs and output. For audio, many projectors contain two 3.5mm connections, one for transmission and one for the reception. Thus, if this access point can only take in sound, you can only use it to listen to audio. Most projectors have A/V plugs that can pass through the audio signals, includingģ.5mm jack inputs and outputs: You should verify the sort of 3.5mm jack the projectors has, as some only have one (either the output or input). There are three methods of speaker setup. Projector connected to a laptop The way to connect the projector and speakers Unfortunately, if the projector only has video inputs, you’ll have to find an alternative method of speaker setup. S-video (that is an outdated sort of analog video stream).Composite Video System (that has data traveling in one cable like the original video signal).Component Video (which has three different signals).Projectors may support many video connections at once, including but not limited to Some older projectors may only have a VGA port for communication and cannot receive sound as they display moving images. Modern projectors are equipped with various video and audio transmission ports, including HDMI, MHL, USB, and RCA composite. The primary purpose of a projector is to transmit and playback video. Conclusion How will a projector receive and send audio (sound)?.How to set up audio for a projector with no audio connections?.Passive speaker setup (using an A/V receiver).Active speaker setups (without using an A/V receiver).The way to connect the projector and speakers. How will a projector receive and send audio (sound)?.Now, how do you hook speakers up to the projector? Is an appropriate audio cable for projector enough? Let’s look into more details. However, the pleasure of watching a movie on a smart home projector isn’t complete without perfectly timed sound. Projectors play a vital role in delivering presentations, films, and other media in both professional and academic settings.
