Introduction

The Midas XL42 is a 1U rack mounting, dual channel creative equaliser incorporating the XL4 four-band

parametric equalisation and XL4 mic/line pre-amplifiers with +48V phantom power.

Each channel has input gain, output level and pan rotary controls, 10-segment LED metering 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 pre-amp 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
XL42s 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 and R outputs may then be routed to the master console via any convenient point, such as, 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.

Before You StartBefore You Start

Installation Precautions

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.

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 AC 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 fuse holder) and
that the correct mains supply voltage is selected.

Safety Warning

To completely disconnect this equipment from the AC mains, set 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. Please note that 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:

The +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.

After You Have Unpacked the UnitAfter You Have Unpacked the Unit

Before unpacking the XL42, check packaging for signs of damage, as this could be an indication of damage to the
unit inside.

After unpacking the XL42, check the unit for signs of damage to the casing. Damage to consignments must
usually be reported to the courier within 24 hours in order for a claim to be made.

Please retain the packaging for your XL42, as it will prove useful if you need to transport the unit.

Please also retain the XL42's Operators Manual (this document) and any other associated documentation.

The XL42 is a highly featured 1U 19” rackmount, dual channel strip. The unit is split
into two identical channel strips, each with identical functionality but having
independent inputs and outputs.

Power On/Off switch: Conventional latching type switch,
which is on when in its fully in position and off when fully out.
The action of the switch is firm but does not require excessive
force, which may damage the unit. A red LED, to the left of
the power switch, illuminates to indicate that the XL42 is
receiving mains power.

Ø switch: Phase switch inverts the input
signal by applying a 180° phase shift.

PAD switch: line/padThe switch provides 25dB of
attenuation to the input signal and allows the
connection of high output microphones or line level
signals. If using the XL42's optional transformer­coupled input, the pad greatly reduces the risk of
saturation at very low frequencies.

allows connection of devices that require
phantom power, such as, condenser
microphones, direct inject (DI) boxes etc.

The bass, lo-mid, hi-mid and treble bands use dual concentric rotary controls. The outside ring controls the band
cut and boost in the range -15dB to +15dB. The inner ring of the dial controls the bandwidth of the filter in the
range 0.1 to 2 octaves (with a centre detent at 0.5 octave).

Left / Right Output: Balanced XLR output from the channel strip.

The output signal will be a combination of the link input plus the output from the XL42's input
channels. If pan is selected on either of the inputs, the outputs will be a stereo combination of the
input channels plus the link input. If pan is disabled on the channels, the output will be a
combination of the input channel and the link input only.

Please note that if one input channel has pan enabled and one does not, the channel with pan
enabled obeys the pan law of the pan pot. However, no signal is introduced into the other output.
Only when both channel pan switches are enabled does the unit enter full stereo mode, that is,
either output can be a combination of either input.

Maximum output level: +21dBu

The Left and Right Outputs may be internally configured using jumpers to be pin 2 or pin 3 hot.
Factory default setting is pin 2 hot.

Supply voltage selector switch:

The supply voltage is switchable between 115VAC and

to be used.

Caution!
The supply voltage selector switch must be set BEFORE plugging the unit into the mains.
UNDER NO CIRCUMSTANCES should the switch be changed whilst the unit is plugged in.

Remote Control Automute Assigns: The 9-pin plug for the

Automute system allows up to 8 Automute channels. The input
channels of the XL42 can be set to mute on one of these 8 Automute

As shown in the diagram above, each channel has its own input plus the output from the previous XL42 so that at
the last point of the chain, the output is a combination of each input.

Depending on the use of each channel PAN, this may be a stereo image or all the left-hand channels grouped and
all the right-hand channels grouped.

Optionally, you may wish to use the Automute feature. Here the output from the master console (any MIDAS XL
series) is inserted at the top of the chain and linked into each unit.
