Discussions about the Bose S1 Pro system

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 system.

Last night I used two S1s for my acoustic duo (one guitar, two vocals).  I ran the guitar and vocals into my T1 mixer which was connected to input 1 on an S1 with a TRS 1/4" cable.  I then ran another TRS 1/4" cable from the output of the first S1 to the second S1.  I set the input volumes of each S1 at noon to control the volume from the mixer.  I was surprised that the volume of the first S1 was very quiet while the second in the chain was loud.   I swapped the positions of the two S1s to confirm there was no problem with the first S1.  Same result.  I ended up having to run the mixer volume higher and the second S1 closer to 10 o'clock on the volume to even it out.

My question is why?  I know the output of the first S1 is set by the channel volumes so that is probably why, but the way it worked seemed very strange to me.

Hi DavidE2,

You're right, the S1 Pro Line Out is post-volume-controls. The signal at the Line Out is hotter than the inputs. As a result, you'll have to set the second S1 Pro volume lower than the first.

This may seem odd at first, but imagine a situation where you use the S1 Pro as a stage monitor and use the Line Out as a feed to a Front of House system. Whoever is controlling the Front of House system wouldn't be able to see the controls on the S1 Pro, so they won't have any expectations that everything would match.

Since you're using a T1, you can connect the T1 Main Output to the first S1 Pro and the T1 Aux Output to the second S1 Pro. Then you can have two separate mixes. 

Here's more information about T1 Aux.

If you don't need separate mixes, then stay with the daisy-chain connection from the first S1 Pro to the second S1 Pro.

Yeah, don’t want separate mixes.    Honestly I’d never send the output of the S1 to FOH.  In my experience, they want a nice mic level signal and one that will change if I need to adjust the volume of the monitor during a gig.  

The S1s worked well, but I really missed having a subwoofer.
