IMPORTANT SAFETY INSTRUCTIONS
These symbols are internationally accepted symbols that warn of potential hazards
with electrical products.
The lightning flash with arrowhead symbol, within an equilateral triangle is
intended to alert the user to the presence of uninsulated “dangerous
voltage” within the product's enclosure that may be of sufficient magnitude
to constitute a risk of electric shock to persons.
The exclamation point within an equilateral triangle is intended to alert the
user to the presence of important operating and maintenance (servicing)
instructions in the literature accompanying the appliance.
1. Read these instructions.
2. Keep these instructions.
3. Heed all warnings.
4. Follow all instructions.
5. Do not use this apparatus near water.
6. Clean only with a dry cloth.
7. Do not block any of the ventilation openings. Install in accordance with the manufacturers
instructions.
8. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus
(including amplifiers) that produce heat.
9. Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two
blades with one wider than the other. A grounding type plug has two blades and a third grounding
prong. The wide blade or the third prong are provided for your safety. If the provided plug does not fit

10. Protect the power cord from being walked on or pinched particularly at plugs, convenience
receptacles, and the point where they exit from the apparatus.
11. Only use attachments / accessories specified by the manufacturer.
12. Unplug this apparatus during lightning storms or when unused for long periods of time.
13. Refer all servicing to qualified personnel. Servicing is required when the apparatus is damaged in any
way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into
the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has
been dropped.

Contents
Thank You for using a Midas XL42 dual channel creative equaliser. The XL42 has been developed to meet the needs of
demanding live sound engineers and meets the quality of build and performance that you would expect from a Midas.
The XL42 is backed up by the standard Midas Three Year Warranty.
Please take the time to complete and return the registration card.
Finally,
Enjoy your new Midas XL42!
In view of this flexibility, we hope that you will spend a
little time reading through this operator's manual, as this will allow you to obtain the best results from your XL42 with a
minimum of effort.
Contents

The Midas XL42 is a 1U rack mounting, dual channel creative equaliser incorporating the XL4 four-band parametric
equalisation and XL4 mic/line preamplifiers with +48V phantom power.
Each channel has input gain, output level and pan rotary controls, 10-segment metering LED plus a switchable insert
send and return point. The XL42 also features Automute scene control from the Automute masters of XL consoles which
are enabled by DIP switches on the rear of the unit.
The purpose of this unit is threefold:
1.To improve the audio quality of an inferior console by adding a Midas mic preamp and EQ.
2.To create custom mixing consoles through the ability to daisy-chain multiple units. When linked together, the
combined outputs will sum, producing discrete L&R channels.
3.If a production requires, for example, 10 channels more than the input capacity of the master console, five XL42's
can be fitted in a standard rack together with any required dynamic processing, which can be inserted via the
XL42's insert points, thus creating a custom 10 into 2 mixer via the output daisy chain feature. The resulting L&R
outputs may then be routed to the master console via any convenient point i.e. a pair of aux returns, group inputs,
matrix inputs etc.
As a stand-alone unit, the XL42 is ideally suited to applications requiring a high quality front end, such as stereo
recording etc.

Installation Precautions
Voltage Selection and Power Connection
Mains power to the XL42 is supplied by means of a standard fused IEC power socket. The XL42 is designed to operate at
nominal mains voltages of 115V and 230V V a.c. at either 50 or 60 Hz, however upon first use (and whenever the mains
supply is changed) the input voltage selector on the rear of the unit must be set to reflect the local power supply. This
information is also printed on the rear of the unit below the mains inlet socket.
This device must be earthed and must use an approved mains fuse. Before connecting to the mains supply, ensure
the fuse fitted is the correct type and rating as indicated on the rear panel, adjacent to the fuse holder and that
the correct mains supply voltage is selected.
Safety Warning
To completely disconnect this equipment from the AC Mains, turn the power switch to the off position. The power
switch shall remain readily operable.
Do not expose this equipment to dripping or splashing and ensure that no objects filled with liquids, such as
vases, are placed on the equipment.
For safety reasons the earth lead for this unit should never be disconnected. In the event of ground loop
problems, under no circumstances must the mains earth be removed. Instead, disconnect the signal screen at
one end of the connecting cables.
N.B. This can only be done when the unit is being used within a balanced system.
To prevent shock or fire hazard, do not expose the unit to rain or moisture. To avoid electrical shock do not
remove covers. Refer servicing to qualified personnel only.
Attention! Cables
The inputs and outputs are balanced on conventionally wired XLRs (pin 1 screen, pin 2 hot and pin 3 cold). This product
should only be used with high quality, screened twisted pair audio cables, terminated with metal-bodied 3-pin XLR
connectors. Any other cable type or configuration for the audio signals may result in degraded performance due to
electromagnetic interference.
Note that +48V phantom power can only be used with balanced cables.
Electric Fields
Should this product be used in an electromagnetic field that is amplitude modulated by an audio frequency signal (20Hz
to 20kHz), the signal to noise ratio may be degraded. Degradation of up to 60dB at a frequency corresponding to the
modulation signal may be experienced under extreme conditions (3V/m, 90% modulation).
No permanent damage or degradation of performance will be caused by these conditions.
Do not install this unit in a location subjected to excessive heat, dust or mechanical vibration. Allow for adequate
ventilation around the unit, making sure the unit's vents are not obstructed. To avoid excessive heating of the unit,
avoid mounting the unit directly above power amplifiers or other devices that radiate significant amounts of heat.
Where necessary, use fan-cooled racks.
