monitors in mono problem

bought a pair of Yamaha HS7 monitors. I bought a stereo 3.5 mm jack to duo stereo 6.35 mm jack adapter to plug into my audio output from my Mac mini.I bought 2 stereo 6.35 mm jack to jack cables out from the adapter to the balanced inputs of my Yamaha speakers.The speakers work but everything is in MONO ????

Any help please.

Mac mini, macOS Sierra (10.12.5), Logic 10.3.1

You're audio output from your Mac Mini (analog) is stereo, unbalanced.


So coming out and splitting to two STEREO 6.35 and then going from there into the balanced XLR's could well confuse the signal path.


Your 3.5mm to duo stereo 6.35mm converter will split the whole signal into 2 stereo paths and those 2 stereo paths will then be fed into your monitors giving you identical signal in both monitors.


You'd do better going from your Mac Mini 3.5mm stereo to 2 mono. Then just simply one into the left speaker and one into the right. Unless you want to wire some unbalanced XLR's to your monitors just stick to the jack input.

your first adapter does not split your stereo. it distributes stereo from 1 stereo to 2 stereo outputs (not to 2x mono L+R, which is what you really want). then you are using 2 stereo cables which obviously transmit an identical signal to the amp and speakers. you never separate left and right channels actually. both sides of your speakers receive exactly the same signal.


2 possibilities:


1 - buy a new adapter stereo 3.5 to 2x mono 6.35. this is the safest option. i recommend this, as Csound did. you may also want to buy 2 mono 6.35 cables, although your 6.35 stereo cables may work as well (but not certain, depends on the new adapter).


2 - open your 2 stereo cables on the jack adapter ends. on one, clip the wire for left signal. on the other, clip right. DO NOT DO THIS IF YOU DO NOT FEEL SAFE ABOUT IT AND KNOW WHAT YOU ARE DOING! CLIPPING WRONG CABLES MAY DAMAGE YOUR AMP AND SPEAKERS! this is the fastest and cheapest option.


since i do not quite understand what cables you are using, better check correct wiring in the manual HS7/8:
