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 just received my L1 and am really eager to use it. But I heard that I cannot use my powered mixer with this due to the fact that it is a powered speaker. I saw on this forum that someone is able to use their powered mixer with theirs. Is there any way I can use these together, and how do I set it up? Thanks!

Hi TerryC,I

Welcome to the Bose Portable PA Community.  Congratulations on getting your L1® Compact.

Is this your mixer?

Behringer Europower PMP2000

If so, you can connect the PREAMP OUTPUT marked LEFT/MONO to your L1®.

Behringer Europower PMP2000 Output 2

Do NOT connect speaker outputs to any Bose device. You may damage the mixer or the L1, or both.

If this is your mixer, the PREAMP Outputs are unbalanced. You can use a cable like this:

¼ Inch  (6.3mm) Tip-Sleeve (unbalanced) to ¼ Inch  (6.3mm) Tip-Sleeve (unbalanced)

Tip-Sleeve to Tip-Sleeve

to connect to the L1 Compact channel 2. Set the ToneMatch switch to Line Level (down position).

If this is not your mixer, please give us a link to the owner's guide for your mixer.

Does that help?

Hi ST,

A couple of typos in your reply:

ST posted:

If this is your mixer, the PREAMP Outputs are unbalanced. You can use a 1/4 inch (3.5mm) to 1/4 inch (3.5mm) cable to connect to the L1 Compact channel 2. Set the ToneMatch switch to Line Level (down position).

¼ Inch Tip-Ring-Sleeve (unbalanced) to ¼ Inch Tip-Sleeve (unbalanced)

Tip-Sleeve to Tip-Sleeve

1/4" connectors are 6.5mm, not 3.5mm (that's 1/8"). Well, neither are exact but that's the common reference

The pictured cable is also a 1/4" Tip-Sleeve  (unbalanced) to 1/4" Tip-Sleeve  (unbalanced), there is no Tip-Ring-Sleeve connector.

 

While we're on the subject, for the OP/general reader's benefit (as I'm confident ST knows this already), connectors don't make a cable balanced or unbalanced, but rather how the cable is wired and to what sending or receiving connection. A 3-terminal connector (TRS, XLR, Phoenix/Euroblock) can be wired either way, but if one end's connection is unbalanced, the entire cable path is unbalanced even if the other end is wired balanced.

Ex: A 2-wire shielded cable with TRS connectors properly connected on either end for balanced signals will only carry a balanced signal if both connected pieces of equipment are balanced. If you plug it between a guitar/keyboard and an amp, it's unbalanced. If you plug it between a guitar/keyboard and the L1 Input 2, it's unbalanced. If you adapter it from TRS to TS or RCA at one end, it's unbalanced.

There are many types of equipment that can receive an unbalanced or balanced connector and will adapt its circuitry accordingly, (i.e. the L1 Compact Input 2 can take a TRS or TS connector), but they cannot tell if the connector is wired properly for balanced or unbalanced connection. They typically expect both ends to have the same type of connector wiring to work properly.

The RANE Library has some great reference material on the subject, and this one is the industry standard among audio professionals for keeping sane with how things should be wired:
Rane Note 110

Sweetwater also has a decent Cable Buying Guide that explains various cable and conector types.

Hope this helps,

Jeff

Corrections done. Thanks for catching those.
