Discussions about the new Bose S1 Pro

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.

2nd. S1 Pro.....couple of questions.

So, after 6 months of using my S1 Pro for small intimate style gigs and street/outdoor performances, I have just purchased a second and plan use both as a full PA., linked together with my one active sub-bass (Samson Auro DS1200 for the heavy duty signals).

I currently drive the sub and the the tops (2 x Yamaha DXR10's in series) separately and independently with the left and right channels of my mixer, using the channel pan controls (after setting each channel EQ), to adjust the overall mix as required.

This works very well for me, and I see no reason not continue this, but with the S1's replacing the DXR's for smaller venues.

I just have a couple of questions

1. I shall obviously need to connect the S1's in series too, so, is the "line out" connection  tip, ring, sleeve or simply tip, sleeve?

2. Does the S1 have a built in limiter or any other sort of overload/clipping protection?

Cheers.......Brian.

 

PS....Back in February, as an "early adopter" of the then new S1, (battery extra) I applied (successfully I was informed), for the "free backpack" offer. That was I seem to remember about four/five months ago...still no sign of it! To be truthful, I'm not really very hopeful of ever seeing it!

 

Original Post

From the S1 manual:

'LINE OUTPUT – Use a ¼" TRS cable to connect the line-level output to the Aux Input of a second S1 Pro, to create a mono two loudspeaker setup. Note: Line Out is post mix.'

Actually, I prefer using a balanced (3 conductor) cable with TRS 1/4" at one end from the output of one S1 and a male XLR connector into one of the input channels on the other.

I hope your post shakes the backpack free for you.  They are quite impressive!

 

1. The S1 has TRS line level output. I've used it with a TRS cable and it works well, haven't tried with a TS cable. 

2. Haven't driven it loud enough to the limit yet so can't comment on the limiter. I DJ but mainly use it as remote fill or background music for cocktails.

I like the idea of you using it with a sub to handle the lows. I'm thinking about doing that too with super small gigs where I don't want to even bring out QSC K8s or CP8s. I pair an EV 12" sub with my 8's. Thinking of even getting a smaller one like the 8" Fishman SA Sub for the S1s. Too bad Bose doesn't make an active B1.

@theonemanband I have copied the part of your post related to the backpack to S1 Pro Battery included and S1 Pro Backpack for early adopters. May 10 2018

To all, please post further comments about the backpack in this discussion.

So, first gig, cabled up as above, Mixer Channel one - Active  Sub........... Mixer Channel two - S1 tops [2xS1 daisy chained in series].

Not very successful, found it difficult to balance the tops. The XLR inputs on the S1 seem partularly hot and the TRS line out to the 2nd. S1 is post mix, resulting in constant clipping at the desired volume level.

2nd gig, different story; cabled up the “normal” way.......

mixer channels# 1+2  > sub inputs# 1+2  > sub outputs# 1+2  > S1 Pro’s left & right.

The sound was excellent but I do still have the same two questions.

1. Does the S1 Pro have any in built compression or limiter protection?

2. Will irregular clipping (intermittant red signal) cause any permanent damage to the S1 Pro?

Using a Tip-Ring-Sleeve to Tip-Ring-Sleeve  cable from the first S1 Pro to the second S1 Pro will give you a better match for signal level and impedance than a Tip-Ring-Sleeve to XLR.

It is easier to manage the relative volumes of two S1 Pro systems with separate inputs (as you did for the second gig) as compared to daisy chaining them (as you did for the first gig). This is because, as you noted, the S1 Pro line out is post-mix.

but I do still have the same two questions.

1. Does the S1 Pro have any in built compression or limiter protection?

Let me investigate.



2. Will irregular clipping (intermittant red signal) cause any permanent damage to the S1 Pro? 

No. However, if you hear audible clipping, or distortion, turn down the volume.
