RCA to mini-jack (3.5mm) to headphones?
Hi, I am using Panasonic HC-V700 camcorder for recording a YouTube show with 2 talents, i.e. 2 mics. Both mics are wireless lavaliers. The receivers are plugged into a passive sound mixer, which converts them to left- and right-channel audio, and then inputs it into a single available 3.5mm external audio input on the camcorder. The setup is fine and works great, however I would also like to monitor sound on the go. This is what I've come up with: since HC-V700 doesn't have a headphone audio output, I decided I may use an AV Multi output, which is basically an AV Multi to Component (for plugging into the TV, for example). I've tried plugging in only the RCA cables into the TV and it works well outputting just sound (exactly what I need). Now I need a setup, which would allow me outputting sound to a paid of headphones in a studio. I've ordered an RCA (female) to mini-jack (female) adapter, which should theoretically work, except for one concern. In case of a TV, it can provide its own power to produce sound, but headphones have no power. I don't know if the camcorder is powering the sound output, or the receiving device. Would my setup Camcorder->AV Multi->RCA->Mini-jack->Headphones work in your opinion? Thanks in advance!
Why do new tvs not have headphone jacks?
Cost........ pure and simple. TV manufacturer's are driving their own pricing down and down in efforts to out-do each other for market share. Every spare cent of unnecessary cost is being trimmed out. It's kind of ironic really. For decades TVs have had headphone sockets that no one has bothered to use. Now that TV sound is so poor and there's actually a use for them it's the time that TV manufacturers are dropping the feature. There is one other issue. It's safety and the fear of litigation. Modern flatscreens are very light. It doesn't take much to topple them. Having a headphone wire trailing across a room is a massive tipping risk. Either someone falls over the cable or the headphone wearer tugs on it by accident and the TV goes over. Some enterprising Lawyer somewhere will have won a case for a replacement TV and hefty damages. TV manufacturers aren't stupid. If the Law is an *** then they'll respond in kind and cut their risk exposure. Sad, but true.
Will a headphone with 30 mm Headphone Driver work with 3.5mm Jack?
one has nothing to do with the other
What's the output voltage of a smartphone's headphone jack (3.5mm jack)?
There is no standard on output voltage of headphone jack. Since every device is different and will vary based on many parameters. Laptop may be able to provide higher voltages and also some high end smartphones have dedicated DAC. Portable Mp3 players have lower battery capacity which can’t provide high voltage. So this one varies.Generally your audio is analog so you can’t have single voltage level for output. It’ll vary based on volume, song, your headphones etc. However there is line level specification which specifies maximum voltage range (2V peak to peak for sine wave and 100 to 600 ohm impedance). You can read it here Line level
How do I convert red and black speaker wire to a 3.5mm audio jack?
You probably don't want to do that, at all. There is most likely a better way to get an audio signal from point A to point B.Most 3.5 mm jacks that you encounter are stereo jacks--stereo speakers, stereo headphones, etc.Stereo 3.5 mm jacks have three conductors; a tip, a band in the middle called the "ring", and the base of the jack called the "sleeve". You may see these referred to as,"Tip, Ring, Sleeve" jacks or sometimes just "TRS" jacks.In almost all stereo applications, the sleeve is the ground or "common", the tip is left, and the ring is right. To get the left signal, you take one lead from the ground and one from the tip. To get the right signal, you take one lead from the ground and one from the ring. As a rule the black wire denotes negative and should attach to the sleeve (ground/common).Whether hooking "red and black speaker wire to a 3.5 mm jack" will work for you depends on what you are trying to do. 3.5 mm jacks are rarely used for speaker-level connections. They are usually used for low level signals such as microphone inputs, line inputs, and headphones. If you are trying to drive a pair of bookshelf speakers from a headphone jack, you probably won't have much luck because speakers require a much higher signal level than headphones. You would most likely need to insert an amplifier between the 3.5 mm output and the speakers.If you are trying to go the other way and hook the speaker output of some device to the 3.5 mm input of another device, you are headed for heartbreak. Since most 3.5 mm jacks used as inputs are looking for a very, very low level microphone signal, the speaker output will be way too loud and the signal will be hopelessly distorted and the microphone input will be irreparably damaged (probably). If the 3.5 mm jack is on a cell phone, you've likely got a four conductor jack: A tip, two rings and a sleeve. On Apple devices, the tip is left, the ring next to it is right, the next ring is ground, and the sleeve is reserved for a microphone.a picture of various 3.5 mm schemes found in nature can be seen, here:
How do I listen through headphones if my system has no headphone input port? I don't like Bluetooth.
Buy an inexpensive headphone amplifier from Fio or someone else. Just make sure that it has a 3.5mm input jack or USB port (most have that) based on what your device has.If your system has two RCA out jacks, you can adapters that will convert the two into a single 3.5 mm jack. However, you will still need to run this into a headphone amplifier because the output impedence won't be right and will need to be corrected by the headphone amplifier. You can find these on Amazon, Ebay, or other sites. Some go for as little as $15.
What is the difference between 3.5 mm jack in mobiles and laptops?
Let's try to understand with basics :As shown in the image, there are mainly three types of ports. We see mostly TRS and TRRS types jacks.TS type jack does not support stereo sound and microphone. It means there is no left and right only mono. Both side of headphones will give you the same sound. TRS type jack supports stereo sound but it does not support microphone. You can only listen to music but can not make calls with these type of headphones.TRRS type jack supports both stereo and microphone functionality.Now we will try to understand it thoroughly. By comparing the above two images, one can understand the positions of left, right and microphone.Now comes the tricky part. When it came time to add in a microphone channel, things went a little pear-shaped because there were two schools of thought on how to wire up the connections. One called CTIA, and another known as OMTP. Some manufacturers chose to change the socket in order to make the sleeve contact as the ground line (OMTP), while others chose to leave the ground contact where it was and squeeze the new channel in on the sleeve (CTIA). It is shown in the below image.So no matter what you have, laptop or mobile phone, your manufacture could have followed either CTIA standard or OMTP standard. It is the reason behind compatibility issue with headphones. So it is possible that your mobile phone headphones don't work with your laptop or vice-versa. How to overcome this problem ?Simple. Use stereo headphones without microphone (TRS type). Means having only two strips in jack instead of three. Let me make you understand through image.As we can see, the position of left and right remains same, it will work with both CTIA standard and OMTP standard. Position of microphone will be covered by ground. So it won't affect the compatibility. If you only want to listen to music, always buy headphones without microphone because of this you won't need to worry about compatibility of the headphones.What if you have already bought incompatible headphone but you still want to use it ?Simple. Buy one of this. It will (probably) solve the problem. Why probably ? Because this item also follows either CTIA or OMTP standard. But it cost way more less compare to headphone. So buy one of them and chech if it works. If don't then buy another one.
RCA cables...red yellow white vs. red green blue?
As long as the same colors are used on both ends.
