Repacking If the product is to be shipped to Speck Electronics for service or repair, attach a tag to the product, identifying the owner and indicating the service or repair to be accomplished. Include the model number and serial number of the product. -
Page 6: Standard Accessories
The three conductor line cord and plug assembly is wired in accordance with NEMA convention (line - black, Neutral - white, and safety earth - green). When using the LiLo and its power supply outside North America, it may be necessary to adapt a different power cord for that specific country. -
Page 7: Lilo Features
Chapter 1 Introduction Section The LiLo is a modular mixer design with 16 or 24 input channels and a master LiLo Features module fit into a solid frame. All inputs, outputs, and bussing are fully balanced with transformers on the mix and group outputs. All input channels have secondary configuration switches as well as configuration jumpers on the circuit board. -
Page 8: Dual Path Signal Routing Feature
Chapter 1 Introduction Section Dual Path Signal An important benefit of the LiLo is the ability to mix 32 line signals in “real Routing Feature time” from the standard 16 channel mixer (or 48 with the 24 channel LiLo). You could, for example, have the 16 outputs from D/A converters (Protools, Radar, etc.) connected to the 16 "Line-B's"... -

Page 13: Chapter 2 Installation
AC distribution, grounding, and shielding techniques. If the LiLo is being installed into a larger studio or as a sidecar/expander to a host console, it may be necessary to retain the services of someone experienced in these matters. -
Page 14: Environmental Considerations
Electronic equipment such as power amplifiers, power supplies (especially wall mount type), video monitors, computers, certain synths and samplers must be located away from the LiLo and its associated cables. It may be necessary to alter the positions of certain equipment that you feel would cause buzzes or hums in the mixer system. -
Page 15: Removing Modules For Service
Chapter 2 Installation & Setup Due to the high performance of the LiLo, it is recommended that you use only the highest quality audio cable. A high quality cable by definition is a cable that provides good mechanical strength, high microphonic noise immunity, high frequency response, low crosstalk, and 100% shielding ability. -
Page 16: Cleaning
Chapter 2 Installation & Setup Cleaning The module and chassis are a high quality painted surface and the panel lettering is applied using a silkscreen printing technique. To clean the top or rear panel, wipe the surface gently using a soft lint-free cloth to avoid scratching the panel or markings. -

Chapter 3 Operation Section Input Channel The Lilo has separate line amp modules for each input as well as 1. Line Input Select separate trim controls. This switch selects the Line-A or Line-B line amp module. Two yellow LED's display the status of the switch. - Page 20 AFP, GFP, GSC Configuration Switches 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 the aux sends and group assigns.
- Page 21 Chapter 3 Operation Section Aux Sends Each input channel has four aux sends that can be switched pre or post the faders. The Pre/Post functions can be configured to accommodate different mixing applications. Adjusts the level to the Aux busses 1 and 2. Aux 2 can be 16.

This active-balanced input is suitable for any high level line source. The XLR connector and ¼” TRS jack are wired in parallel. Each input channel on the LiLo has a balanced send and return available via 23.

By default, the LiLo is shipped with this jumper in the "Pre Fader" position. This push jumper affects the “Pre” setting for Aux Sends 1 through 4. Refer to Figure 9a below for the location and setting of this jumper.

Monitor Master control. Each switch has a red LED. The source for the monitor can be: Mix- This is the stereo mix of the LiLo post the stereo master fader DAW- This is any mono/or stereo signal that is connected to the DAW return. - Page 26 Chapter 3 Operation Section 29. DAW Return Level This trim pot adjusts the level of any external stereo source connected to the DAW returns on the rear panel. This could be the stereo mix of a DAW or any other stereo source. This return is selected with the DAW, or the Mix+DAW Monitor Source Select switch.
- Page 27 Operation Section Aux Return Section There are two aux return sections incorporated into the LiLo. Each stereo return includes a stereo Return Level control, Pan control, Mix Assign, Group Assign, and in-place Solo switch. This dual pot simultaneously and equally adjusts the 34.

Chapter 3 Operation Section Master Module I/O connectors The master section has a full compliment of XLR and 1/4" TRS jacks for the main Mix Outputs, Group Outputs, Monitor Outputs, Aux sends and Aux returns, the stereo DAW Return and 2 Track Return, and a external V.U. Meter Output. - Page 31 Chapter 3 Operation Section 46. Group Output The balanced group outputs are adjusted by the Group 1 and Group 2 masters Connectors [39] on the master module. Active-Balanced outputs are standard on the group outputs but may be ordered with transformer-balanced outputs. Each group channel has ¼"...

- Page 33 Chapter 3 Operation Section 54. Chassis Ground Lift When depressed, this switch disconnects the chassis ground of the LiLo from the power DC common. This can reduce the chance of ground loops and eliminate unwanted hums or buzzes. A few words about hums, buzzes, and the role of a ground lift.

Proper AC grounding When you are evaluating voltage and current requirements for your audio system, it is important that your LiLo and/or audio system does not exceed the capacity of your AC service. You should make certain that the earth (green) -
Page 36: Clock Noise And Ac
Chapter 4 Wiring and Other Clock noise and AC Clock noise is one of the greatest enemies of the audio racks AC system. If a computer or any microprocessor based device (most samplers and effects are) emits or somehow couples its clock signal with the neutral or earth of its own power cable, it will contaminate your AC system and carry the clock noise into other equipment;... -
Page 37: Emi And Rfi
The occurrence of EMI (Electro Magnetic Interference) and RFI (Radio Frequency Interference) in a contemporary studio system should be of great concern and not overlooked when installing the LiLo. EMI is defined as any unwanted signal which adversely affects the operation of the LiLO or your audio system.
