Introduction to the XL4
The XL4 was born out of a dream to design an analogue state of the art live mixing
and recording console with unparalleled performance/features intrinsic with intuitive
layout and operation. The vision required the analogue sound path to be controlled in
the digital domain via a high degree of signal routing and moving fader automation
enabling the live sound engineer whether in a touring or theatre production
environment to utilise automation functions in order to enhance mix efficiency and
performance to performance consistency.
The benchmark for the XL4 was the XL3 console which during production since 1990
gained a worldwide reputation for unequaled sonic performance and system
transparency culminating in its award for best live sound mixing console 1993 and
1994.
Bob Doyle, Midas Sales & Marketing Director, spent ten months finalising the XL4
specification, discussing its concept with world class sound engineers and rental
company heads as well as theatrical production designers and artists alike. The criteria
was to develop a mixing environment which enhanced the creativity of the mixing
engineer by automating the repetitive functions of specific mix and cue requirements,
thus leaving he or she free to concentrate on the main thrust of live mixing by
reproducing the Artist’s music as it should be.
In our opinion, the XL4 combines all these criteria in a coherent, easy to operate
mixing aid with unsurpassed sound and sonic quality.

Midas XL4 Features
48 Mic Inputs.
Direct Outputs.
The XL4 features a new mic amplifier which further improves on the XL3 design giving increased
gain range and lower distortion whilst retaining the XL3's constant HF bandwidth topology which
assures excellent amplifiers stability, RF rejection and noise performance at all gains.
Every input module is fitted with a direct output as standard with its own level control and front
panel switching which selects the source from post fader, pre fader or pre insert and equaliser.
16 audio sub groups.
The 16 main audio groups can be assigned to any of the 8 automute groups and to VCA control
from any combination of the 2 motorised grand master faders. A safe switch is again included for
each group. The input for the groups is normally derived from the 16 group busses but for monitor
applications the fader change over routes the 16 mono aux busses to the group faders.
Equaliser.
Inserts.
The sonic performance of the legendary XL3 equaliser is maintained including the full parametric
mid's and traditional Midas bass and treble shelving responses. In addition the treble and bass
sections now have an extended frequency range and are switchable to full parametric operation.
Each channel has a half normalised fully balanced insert send and return point which can be
switched in or out from the front panel and set as either pre or post equaliser.
Input metering.
Audio busses.
These peak reading meters cover a 60dB range in 3dB steps and can be switched globally to
monitor pre fader signals or pre insert and equaliser signals.
Each channel can be routed to any combination of 42 audio busses comprising of 16 mono aux'es,
8 stereo aux'es, 16 stereo groups and 2 stereo masters. All this is switchable on the module front
panel but also via the automation control.
VCA and mute busses.
Each channel can be controlled by any combination of the 10 motorised VCA master faders and 8
mute masters. Assignment of these busses is again switchable on the module front panel or by the
automation control. A safe switch disconnects the channel from all mute groups and an isolate
switch removes the channel from all VCA control.
Line inputs.
A separate Hi Z line input with its own dedicated gain control is incorporated which is ideal for
playback of recorded material. Global change over from mic (record) to line (playback) is easy
because it is under automation control.

Group aux inputs.
An additional 16 inputs with treble and bass equalisation can be routed directly to the groups or via
a pan to the masters mix and can be further controlled by assignment to any of the 10 VCA masters.
Master.
The stereo master module provides the main left and right console outputs plus 4 more record
outputs and a mono output. A solo to master facility is incorporated on the left, right and mono
outputs to aid the engineer at sound checks.
Output meters.
28 peak reading meters (each covering a 60dB range in 3dB steps) are used to monitor all the main
outputs i.e. 16 groups, 8 matrix, 2 masters and 2 local outputs. They and can be switched globally
to monitor pre fader or post fader signals and can also be used to monitor the 24 aux outputs.
10 input VCA faders.
10 motorised VCA master faders control the channel and aux inputs whilst a further 2 VCA grand
master faders control the audio groups. Each VCA master has a solo switch which gives the
engineer an opportunity to monitor the signals within the VCA subgroup. Also incorporated is a
VCA mute which act on post fader signals only and effectively adds a further 12 automute scenes
to the existing dedicated automutes.
Matrix.
As standard the 8 matrix outputs derive their signals from the 16 audio groups, left and right
masters creating a 18X8matrix. The module also houses the stereo aux masters which have their
own outputs at all times but which can be routed directly into the matrix giving an additional 48 X
8 matrix sourcing direct from the input channels.
Automutes.
The 8 automute masters can be assigned to any input or audio group and act on pre fader and post
fader signals. Apart from assignment the operation of these mutes is entirely independent of the
automation system.
Automation.
The automation system can store and recall up to 2000 scenes. All channel routing and major
functions are automated as well as all major output mutes. The 12 motorised VCA master faders
give dynamic control of signal levels within the console and all automation information can be
exported or imported in a variety of different mediums for storage or console and system linking.
