Bose S1 Pro 

Designed for musicians, DJs and general PA use, the S1 Pro is the ultimate all-in-one PA, floor monitor and practice amplifier that's ready to be your go-anywhere Bluetooth music system for nearly any occasion. 

This is the place to discuss the S1 Pro.

Line level input or mic level input on S1 Pro

On the S1 Pro combo inputs, is there a difference between using XLR cables vs. 1/4" cables? For most of the PA systems I've owned in the past, the XLR input has been mic level and the 1/4" input has been line level so I'm wondering if there is a difference here. Specifically, I'm wondering whether there would be a difference using a 1/4" TRS cable or an XLR cable from my mixer to the S1 Pro.

Great question.

The input sensitivity is higher with the XLR inputs.

For most of the PA systems I've owned in the past, the XLR input has been mic level and the 1/4" input has been line level so I'm wondering if there is a difference here. Specifically, I'm wondering whether there would be a difference using a 1/4" TRS cable or an XLR cable from my mixer to the S1 Pro.

You can see the difference here:

Either way, when the S1 Pro Channel input lights hit red, you are clipping, and you've reached the maximum usable volume.  With the mixer, if the XLR outputs are line-level and the 1/4 inch Tip-Ring-Sleeve outputs are line-level, it won't matter which type of cable you use. They'll both get the job done, although the volume control setting will be lower with the XLR connection.  That doesn't indicate more headroom. The maximum usable volume is the same either way.

Does that help?
