1. Line Input Select - Each input module on the LiLo has two balanced XLR inputs. This switch selects the Line-A or Line-B input.  The "Dual Path" feature allows both line inputs to operate at the same time (see #10 and #12).

2. Line-A Gain Trim - This trim control provides up to 12dB of gain for the Line-A input .

3. Line-B Gain
- This control provides up to 12dB of gain for the Line-B input.

4. Insert Select
- Each input channel on the LiLo has a set of balanced insert connectors.  When this switch is depressed, any audio device connected to the insert connectors is inserted in the channel's audio path.

5. Phase -
This switch reverses the polarity of the input signal by 180 degrees.

6. Input Level Control
- This 100mm slider adjusts the level for the input channel.

7. Pan Control
- This center detent pan control places the input signal anywhere in the stereo left/right perspective.

8. Mix Assign
- The Mix assign switch, in conjunction with the input channel Pan Control, allows an input channel to be mixed to the left/right main output.

9. Group Assigns
- The GRP 1 and GRP 2 pushbutton switches allow an input channel to be assigned and mixed to the two individual subgroups. The group assigns operate independent of the channel's pan and L-R assigns.  The GC2 configuration switch can be set to allow the group assign to follow the pan control.

10. Group Select (Dual Path) This switch can double the input power of the LiLo by establishing a "Dual Path" for each input channel.  When depressed, the source for the group assign switches is any signal connected to the Line B input.  This could be the multiple outputs of D/A converters.  Simultaneously and independently the signal connected to Line A input is mixed on the fader to the L/R mix.   

11. Aux Sends - Each input channel has four aux sends that can be switched pre or post the faders.  When needed, Aux 3 and 4 can be selected to operated only from the signal connected to Line B.

12. Aux 3/4 Select
-This function is similar to the Group Select (#10). When depressed, the source for aux sends 3 and 4 is any signal connected to the Line B input. 

13. In-Place Solo Switch
- Depressing this switch allows you to isolate any input channel to the monitor while maintaining stereo perspective.

14. Mute Switch
- Depressing this button eliminates all signal flow to the channels left/right mix, group assigns, as well as the aux sends. 
The rear panel of the
LiLo Mixer has over 100 balanced input and output  connections. 

Each of the input channels has a balanced XLR Line In A connector,  balanced XLR and TRS connectors for Line In B, balanced TRS connectors for the Inserts, and a balanced TRS Direct Out connector.
15. AC, GC1, GC2 Configuration Switches 
We believe a mixer should present the user with a never-ending choice of signal routing capabilities.
Each input channel on the LiLo has a secondary level of signal routing that is made possible with three push switches that are accessible via small holes in the panel. These switches change the configuration of many controls such as aux sends, group assigns and pan assignment.   A tertiary level of configuration is also available by way of jumpers on each circuit board.
