Using a stereo mixer with an L1

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

The inputs on the L1 Model 1S, L1 Model II, and the Compact Channel 2 are MONO. 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.

Start with the Input Trim set to 3 and adjust so that you get a solid green signal. Occasional flickers of amber are fine.

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

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.

Here are a some examples of how you can get a mono output out of your stereo mixer.
