There are basically three levels in audio. Microphone level which is the very low level put out by a microphone. Speaker level is the very high level put out by a amplifier that feeds a speaker. Line level is the middle level that is used to feed audio between components. Consumer audio devices usually use a RCA connector for line level.
audio line out is a port that is alot like a headphone jack but it usually dosent shut off your speakers.
No. It only provides video output
No, it can output any type of audio.
True. The line in the connector is a socket used to attach an audio source. The headphone connector is a socket that is used to attach an audio output device.
Mic level is -56 to -40 dbm. Line level is either -10 dbm or 4 dbm. You need a preamp to amplify a microphone to line level.
Assuming you are connected to the audio output connectors on the TV, you might have to turn up the volume of the TV to get any audio to appear at the output connectors. If it is a high end set, go into the audio menu and switch the audio output to FIXED. This will give you full level audio at the connectors and then turn down the sound from the TV speakers. Don't use the internal speakers when using the sound system.
Connect the audio output of the Casio to the line input of your sound card.
There are several computers in the Macintosh range from the Mac Mini to the Mac Pro. What ports you have depends on the type of Mac you have but they will have ports such as: Gigabit Ethernet port Mini DisplayPort Audio in/out SD card slot FireWire 800 port USB 2.0 ports Optical digital audio input and output TOSLINK ports Analog stereo line-level input and output minijacks
Audio and Visual output is visual and audio
If I understand the question, you are trying to intertwine different functions. Like your ears, the audio input jack receives an audio source, while the audio output jack transmits outputs audio content - similar to your mouth. If you are trying to redirect the input audio directly to the audio output port you will need a "passthru" (aka monitor) function. -P2E
Yes, you can connect the audio of your HP Pavilion to a home theatre receiver using a 1/8" stereo (3.5 mm) to dual RCA plug y-cable. Be sure to use the line output, and connect the cable to an analog line level (CD in, Tape in, Aux in) jack.
Audio
Audio output frequency is that range of frequencies that can be heard. For humans, that is generally considered to be the range of 20Hz to 20kHz.
