How to test balance between right and left channel

Does anyone know if there exists a simple straight forward test equipment that can tell me whether the left and right channels of my speakers or amps or preamps or CD are outputting the same level/strength of signal?

Can this be done with the help of a multimeter, if so how?

many thanks.

A SPL meter plus a source that provides separate left and right channel signals. I believe there are cell phone apps that provide common SPL meter functions.

If you have a mono source you can measure the output of each channel, BUT measuring the output will tell you nothing about the system’s music balance as the measured signal cannot take into account the room’s acoustic properties.

Brf is correct. In my experience even though the equipment is balanced equally from left to right the room is where the problem lies. This can also be frequency dependant.
