L1 Model II This information is applicable to the L1® Model II
L1 Model 1S This information is applicable to the L1® Model 1S
L1 Compact

Using a stereo mixer with an L1

General principles for connecting a stereo mixer to the mono input on your L1 .

Stereo Mixer

The inputs on the L1 Pro Input 3, L1 Model 1S, L1 Model II, and the Compact Channel 2 ¼ inch jack are MONO. Check to see if your mixer has a MONO output. If it does, then use that.

If your mixer does not have a mono output pan all your inputs to one side (e.g. LEFT) and take the LEFT output and connect that to your L1 .

For best results do NOT use any kind of Y-adapter to connect stereo outputs from a mixer to a mono input on an L1 . See Why Not Wye for details.

If you have questions or comments about this article please post a note in the Bose Forum - Technical Questions.

L1® Inputs

L1® Model 1S Analog Input

Model 1S Analog Input


L1® Model II Analog Input

Model II Analog Input

Setting the Trim Control
  1. Set the Trim control on the power stand to the 0 (zero) position.
  2. Connect the audio source to the Analog Input
  3. Adjust the volume of the Mixer output to the reference or nominal output level.
    • On analog consoles this may be marked as unity or 0 dB.
    • On digital consoles this may be marked as -18 dBFS[1][2]. The exact value (-18 dBFS to -20 dBFS) may vary depending your location[3].
    • Refer to the manual for the Mixer for details.
    • If the Mixer does not have metering or indicators, set the output as high as you can without hearing distortion or seeing red indicator lights.
  4. While playing/singing as loud as you will during your performance, increase the Trim level so that the Signal/Clip indicator glows green or yellow. Occasional flickers of red are okay.
  5. If the Signal/Clip indicator glows solid red or you hear distortion, decrease the Trim level so that it glows only green or yellow.
L1® Compact Channel 2

The Compact is different from the Model 1S and Model II because it can accept stereo inputs on the Channel 2 1/8" and RCA inputs.

Stereo Inputs on Compact Channel 2

If have RCA outputs from your mixer you can connect to the Compact Channel 2 RCA inputs. It's likely that the RCA outputs on the mixer are recording outputs and you may have control the output level separate from the mixer master faders. Please see your manual for details.

If you have a way to convert the mixer stereo output to 1/8" stereo jack then you can connect to Compact Channel 2 1/8" stereo input.

or if your cable has RCA (phono) jacks you can use a cable like this.

Mono Input on Compact Channel 2

Compact Channel 2 Input

Start with the Volume set straight up and adjust so that you get a solid green signal. If you see red, turn the trim down.

The ¼ inch jack input accepts a balanced or unbalanced connection.

Compact Channel 2 Balanced.png

Compact Channel 2.png


Can a stereo signal be used with the ¼ inch jack input?

A ¼ inch Tip-Ring-Sleeve connector carrying a stereo signal should not be used with the analog input on the L1 Compact.

Even though a ¼ inch Tip-Ring-Sleeve connector can carry a stereo signal this is not how this physical connection is used on the L1 Compact.

The ¼ inch jack input on the L1 Compact is balanced, and will therefore subtract the Left and Right signals on a stereo cable and you will hear almost no signal in the L1 Compact.

StereoSourceToCompact2.png


The 1/8 inch jack is STEREO not Balanced

The L1 Compact Channel 2: 1/8-inch jack is STEREO not BALANCED.

The written documentation is incorrect. It says:

1/8-inch stereo input - Balanced analog input for connecting audio sources such as portable mp3 players, satellite radio, laptop computers, video projectors, and smart boards.

Correction

1/8-inch stereo input - Balanced Stereo analog input for connecting audio sources such as portable mp3 players, satellite radio, laptop computers, video projectors, and smart boards.

General Principles

It's easy to make this work. You can pan all your inputs hard LEFT and take the LEFT output and connect that to your L1 . If you have a stereo source and two stereo channels, then you can

  1. Run the left side of the stereo source to the left input on one stereo channel,
  2. Run and the right side of the stereo source to the left side of another stereo channel.
  3. Pan any other inputs hard left
  4. Use the left output of mixer and connect that to the L1 Analog input.

Question: Is there a loss of quality when using only one output (e.g. Left only)?
No loss of quality. See Mixer Left Output Only

Connections

Where possible use a balanced connection between the mixer output and the L1® input.

XLR Mixer to 1/4 Tip-Ring-Sleeve L1®

The output side is XLR so you will also need a converter or cable that is XLR female to Balanced ¼ inch jack Tip-Ring-Sleeve.
