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.

Alternative to dedicated XLR-TRS cables

Apologies if this topic has been covered before, or that I am exhibiting a colossal grasp of the obvious, but I’ve seen many mentions in various forum topics about using an XLR to TRS cable to connect a mixer to something like the L1 Model II base or other similar connections. In many cases, the cable being mentioned had a permanent adapter at the TRS end.

I just wanted to offer an alternative to a dedicated cable like that. I’ve been using a Neutrik NA3FP XLR Female to TRS plug adapter with a standard XLR cable. I found this has offered a few advantages.

Firstly, you can use any XLR cable and not have a dedicated one just to get a TRS endpoint. If a cable goes bad, you can remove the adapter and use it on another cable. I’ve never had the adapter fail, but if it does need replacement, it’s far cheaper to replace than an entire cable.

Secondly, since I have a S1 and a L1, I use different XLR cable lengths to connect a mixer to those units. I have a short, 5’ cable from a mixer that’s close by, into the L1. However, I can use a longer cable if the mixer needs to be further away. Furthermore, in some venues that may offer a PA like a L1, but it’s location from where we may be on a stage can vary. Sometimes I may have to put two 20’ XLR cables together to reach a TRS style input. Point is, I can just move the adapter to whatever cable configuration I require.

Anyway, I’m just throwing this out there for folks to consider as an alternative to a dedicated XLR-TRS cable in case you are not aware of this as an option.

I’m not endorsing, nor do I have any sort of relationship with Parts Express, but this is just an example of where you might obtain such an adapter. This is where I happen to get mine. You can find even cheaper adapters, but Neutrik is a well known, high quality unit.

Hi Pete,

Thanks for sharing your thoughts. You've made some good points above in terms of versatility.

We've talked about this here and Bose recommends that you avoid having convertors attached directly to our devices. These add length and weight to the connection and increase the risk of damage to the jack on the Bose device.

You can get a cable like this accomplish the same things.

Or use one of these at the other end.

ST, I have a question on this topic; I have often used one or both of my Yamaha DXR10 powered speakers to augment the overall volume with my L1 Compact. I send from the Compact output phone jack to channel XLR input on one of the Yamahas using an KLR to phone jack connector, and daisy chain to the second if needed. I get a great sound with this method, but after reading your response to CityFolk I am wondering if this might harm my Compact?

Hi Sweet Clover,

Where is the XLR→ to→phone jack connector?  It sounds like it must be attached to the Yamaha because there's no XLR output on the L1 Compact. If that's the case, there's no concern at the Bose end of things.


My TRS adapter is inserted vertically into my L1 MII base end with the standard XLR at the mixer end and the mixer is adjacent to the base on an elevated platform with a very short XLR cable so there’s little stress to the cable. It dangles straight down into the L1. Therefore, I’ve never had an issue, but good to know about possible damage. I also would use the TRS adapter on my mixer’s AUX out end via a XLR cable using the standard XLR end at the S1. So that should be fine too.

Would be nice if the L1 input had one of those multi TRS/XLR input jacks like the S1.
