L1 Model II

Let's talk about the L1® Portable Line Array Systems

Using proprietary Bose® technology, L1 systems combine  PA and monitors into a single, highly portable unit. The  loudspeaker can be positioned behind or to the side —and you hear what the audience hears.

Highly portable PA and monitor combined for solo performers, DJs and general-purpose use. Fixed vertical control with 180° horizontal coverage Reduced vulnerability to feedback.

Three systems to choose from (Compact, Model 1S, Model II)
Two passive bass module options (B1 or B2)
Consistent coverage and tonal balance, portability and easy setup.

I am doing a wedding in an event space that has a large outdoor patio that is serving as the "designated smoking area" to which I want to send audio. It is near enough (and the doors will open and close so often) that the music in the main room will be heard every time the doors opens so it cannot have a delay.

I have the ability to utilize one of my Line 6 XD-V75 mic packs and receivers to accomplish this with my L1 Compact.  I asked, just in case I could accomplish this with the S1 Pro and a bluetooth unit like the Rainyb unit that you referred to another forum user (that outdoor space doesn't require all the audio that an L1 Compact will produce). 

Thanks, as always, for your quick response and terrific advice!

I just had a thought... one cannot use the S1 Pro (by itself) using its Bluetooth but if the External Bluetooth Unit (that has AptX Low Latency) sends audio to the S1 Pro via a 3.5mm cable, will the Bluetooth unit transmit with a low enough latency that it can be used to send audio to the S1 Pro such that it would work for the application I describe above? 

Thanks for helping me think through this.

Hi invisibleDJ,

To get the full benefits of aptX Low Latency Bluetooth, both the transmitter and the receiver must support it.

That covers the receiver end.

This is the unknown. Does your Bluetooth source support aptX Low Latency? Do you know if the range is adequate for your needs in this situation? Most built-in Bluetooth transmitters (in phones, tablets, computers), I've seen have a range of 30 feet (10 meters) under good conditions, and it could be less through obstructions like walls.

You described your application this way.

There will still be some latency:

  • In the Bluetooth transmitter (especially if your source doesn't support aptX Low Latency - and you have to use an external transmitter that does).
  • In the Bluetooth connection (best case is 40 ms), which will be noticeable to some people
  • In the Bluetooth receiver and the connection to the S1 Pro
  • In the distance from the sound source inside, through the doors to the listeners outside. This may help to synchronize with sounds.

I would use the Line 6 XD-V75 for this application. You know it well, and you're confident with it.

 I asked, just in case I could accomplish this with the S1 Pro and a bluetooth unit like the Rainyb unit that you referred to another forum user (that outdoor space doesn't require all the audio that an L1 Compact will produce). 

As far as experiments go, Bluetooth receivers that support aptX Low Latency are easy to find these days.  If your Bluetooth source also supports aptX Low Latency, it might be worth it to experiment.

Please let us know how things work if you try Bluetooth for this application.

Thanks,

ST
