Hello, sorry for this very unusual request.
Listening to genelec since many years now no other speakers satisfy the ear..for late night listing I just want a single speaker to produce sound eg. like Bluetooth speakers.. what will be the best way to sum both left and right channel signal into a mono signal..for feeding genelec 8010 or 8020.. source will be media players or mobile phones.. any help will much appreciated..thanks

Hello, khalinguyen191999!

One way is to use splitter cable (Y cable). It will convert right and left output channel into one. If you don't want to use adapters, there are also mini stereo jack - mono XLR cables on the market that will do the job.

Thank you for your support!

NO! Don't use Y cables for summing signals, with bad luck you might even damage your equipment. Y-cables are meant for splitting, mixing signals requires resistors, easy enough to fit inside the XLR connector. Do some googling!

Here's one valid schematic:

Fun fact: Most or none of the ready-made cables have resistors, need to do it yourself.

Thanks, janne-koo! My mistake. Better to use mini stereo jack - mono XLR cable in this situation.

A (mini-)TRS(-jack) to XLR cable will not work either, unless it's built for this exact purpose with the required resistors; A store-bought TRS-XLR adapter is more likely to be wired to connect some weird balanced output mobile device.​​​​ A multimeter will quickly reveal the ugly truth, ie. no resistors and the wrong pinout.

​​​​​​​As surprising as it may seem, it is very likely that this kind of a cable can not be bought ready-made.
