Balanced headphones w/ an unbalanced amp

post #1 of 11
Thread Starter 
Can this be done using a balun (Or vice versa - unbalanced headphones with a balanced amp) ?

If so, what would be the downside, compared to just having an unbalanced setup to begin with?

Is this essentially what the re-zero trs adapter does?

Balanced headphone on single ended amp, yes.
Single ended headphone on balanced amp, no.

 

The "downside" is that you need an adapter for the first option (eg. 4XLR to TRS).

"Balanced" headphones are headphones wired up like ordinary stereo speakers, that is, the left and right channels have separate + or ground lines rather than sharing a common ground. From the perspective of the headphone, there isn't a meaningful distinction between + and ground, and you can use "balanced" headphones on many appropriate single-ended or balanced amplifiers, including speaker amplifiers: A lot of people drive the AKG K1000 or HiFiMan HE-6 from the speaker taps, although most headphones are too sensitive to get a lot of audible benefit from doing this.

Using "balanced" headphones requires only a plug adaptor and no additional circuitry. Many cable makers will build high-quality adaptors for you, and it's easy to do yourself if you have the tools and soldering skills.

Sorry to hijack on your thread but if you have SE amp with balanced headphones, does it matter if your source is balanced or not? And what do you mean by a balanced source? Many thanks.

Here's another question.

 

If you have a balanced source, and a balanced amp...but only an rca interconnect cable...would rca to xlr adapters actually work and send a balanced signal to the balanced amp from the balanced source?

A proper balanced connection requires positive, negative, and ground lines for each channel.

 

If you're willing to spend what it takes to have all-balanced hardware, why wouldn't you be using the appropriate cables?

Just curious what would happen. 

 

Soon enough I'll have a balanced headphone amp, and I will ultimately be using balanced cables between my source and the amp.

Or just positive negative for each channel and a common ground.

So I am putting a 4 pin mini XLR into my Q701's. Will this significantly change my sound sig without a balanced amp? I don't really want it to, only when I use a balanced amp. It's really just a fun project. But once I have the 4 pin XLR in place, where can I get a cable that will let me use that jack with a 1//4" jack?

Just make one. You just run the negative signal wire on the adapter to the ground of the 1/4 plug, so two will go there and then you have the R and L channel. Almost all my phones are balanced and I have adapters for 1/8, 1/4 and other balanced outputs. Very versatile.

Problem is, I've never made a cable before. I don't even know what wire to use frown.gif
