LEGEND L10 Controls MIDAS 500 Series Rackmount Chassis -
Controls Controls

Rack Ears – These fixed rack ears allow the L10 to be rack-mounted in a 19″ 3U space.
Feet (Horizontal) – These 4 feet allow the L10 to be placed horizontally on a table or other flat surface. If the L10 is rack mounted and there is no free rack space below, then these feet need to be removed by carefully undoing the screws holding them to the bottom of the chassis.
Screw Holes – These holes on the top and bottom front rails are used to secure the 500-series modules in place on the L10. They are also used to secure blank plates (L1B) to cover empty spaces in the L10.
Module Connectors – These multi-pin connectors are used to connect to the rear connector of any 500-series module plugged into the L10. The pin-out of these connectors follows the standard conventions for 500-series modules for audio input and output, power, phantom power, and ground. The exceptions are for the Aux input and output connections. Check the compatibility of any modules you use by comparing the connector pin-outs shown on page 19 of this quick start guide.
Power Indicator – This lamp illuminates when AC power is applied and the L10 power switch is turned on. It indicates that the L10 internal power supply is working and supplying power to the 500-series modules.
Power Switch – Set this to the Up position to turn on the L10.
Do this after all connections to the 500-series modules have been made. Set the switch in the Down position to turn off the power to the L10.
AC Input – The supplied power cord connects to this AC input.
The L10 has an internal switching power supply that can accept AC mains voltages from 100 VAC to 240 VAC, 50/60 Hz. Make sure the front panel power switch is turned off before making connections.
GROUND LIFT – This switch is used to remove the audio ground in situations where audio hum is present.
AUDIO Switch – This switch 0allows you to link the output of one module to the input of the next module in line, allowing you to create an audio chain of modules. For an example, if the first module is a microphone preamplifier and AUDIO 1-2 is pressed, then the output from the preamplifier will be sent to the input of module 2, such as an EQ.
If AUDIO 2-3 is pressed, then the EQ output will go to module 3 such as a compressor, and so on. In this example, IN 2 and IN 3 XLR inputs are disconnected, and the audio for this chain of modules comes in on IN 1, and out from OUT 3.
IN – This balanced XLR audio input connects to the audio outputs of your external equipment, such as instruments, microphones, and line-level outputs. The audio signals are then passed on to the inputs of the 500-series modules.
AUX IN – This balanced XLR audio input is used if your module has this capability.
AUX OUT – This balanced XLR audio output is used if your module has this capability.
OUT – This balanced XLR audio output sends the output of the module to the balanced audio input of your external equipment.
Use the AUDIO switches if you want to send the audio output directly to the input of the next module in line. In this case the signals are sent internally and no XLR patch cords are required.
COMP BUS – These switches are used for those compressors that allow linking together for stereo or multi-channel compressor applications. Only certain compressors have this feature, and our current Midas 522 compressor / limiter does not.

Power Switch – Set this to the Up position to turn on the L6.
Do this after all connections to the 500-series modules have been made. Set the switch in the Down position to turn off the power to the L6.
Feet (Vertical) – These feet are used when the L6 is placed in the vertical position.
AC Input – The supplied power cord connects to this AC input. The L6 has an internal switching power supply that can accept AC mains voltages from 100 VAC to 240 VAC, 50/60 Hz. Make sure the front panel power switch is turned of f before making connections.

Rack Ears – The supplied rack ears can be screwed to the sides of the L6 to allow it to be rack-mounted in a 19″ 3U space. The feet on the lower horizontal panel have to be removed for the L6 to be fitted into a rack, if there is no free rack space below. The handle and the 4 other feet (vertical) can be lef t in place, as the rack ears cover them.

Getting started

With the power cord unplugged from the L6 or L10, install the various 500-series modules that make up your system. Use two screws to secure them to the front top and bottom rails of the L6 or L10. Carefully read the instructions for your modules so you know the correct operation and follow the recommended connections.
Blank spaces in your L6 or L10 can be filled using the Midas L1B blank plates.
These plates will prevent dirt, dust and other objects from entering the unit.
When all connections are made, and the appropriate switches set on the rear panel, connect the supplied power cord to the L6 or L10.
Some microphone preamplifier modules offer +48V phantom power if your microphone needs it.
Be careful that any 48V phantom power switches are correctly set, because some microphones and audio devices can be damaged permanently by phantom power.
Set the power switch to the Up position and observe that the front panel power lamp is illuminated, indicating that the system is ready for use.
Although the L6 and L10 have a rear panel Ground Lift switch, it is recommended that you only use it as a temporary last resort. The cause of ground loop hums etc should be carefully investigated and eliminated correctly, rather than use this temporary measure.
The ground lift switch does not affect the safety ground connection to the chassis, which is always present.
