Line out - straight to headphone.

post #1 of 6
Thread Starter 
Edit:Not a good idea accordingto the following replies/posts below!

My Fostex hp-p1 has a line out and i can plug my headphone into it(controlling the volume via gain adjustment/ reducing on apps).

My understanding is that the line out bypasses the amp, is this correct?
Do line outs have any output impedance?
Is there any plus or minus to doing the above?
Has anyone else had experience of line out straight to Dap?(DX100 etc).

Thanks in advance.

I thought the idea is pretty dangerous and can actually break your headphone(and hearing), it have something to do with the uncontrollable volume and voltage, its one of those "you can do it , but shouldn't"

Oops, sounds exciting.

 

I did check the volume with a cheap pair of headphones first before I plugged in my good ones.

 

But yes, gotta watch for that uncontrolled volume spike.

According to wikipedia , Line outs or line level output have 100 to 600 impendance , which I guess translate to HUEG

also according to the wikipedia article on it


"Connecting a low-impedance load such as a loudspeaker (usually 4 to 8 Ω) to a line out will essentially short circuit the output circuit, as such loads are around 1/1000 the impedance a line out is designed to drive. The line out is thus usually not designed to source as much current as such a load would draw at normal line out signal voltages. The result will be very weak sound from the speaker and possibly a damaged line out circuit."

 

So I guess yeah, you shouldn't do it

Sure has, and generally in the hundreds of ohm.

Ooh. Sounds like a bad idea.
Lucky i only did it for a 2 minutes then.

Thanks all.
