Overview

X

L-Desk is a modern twist on the classic analogue studio console. It’s designed for tracking or mixing engineers who

r

equire an analogue console within a DAW-centric studio, but don’t want or need the integrated DAW control and analogue

l

evel automation other SSL console products have.

XL-Desk is in many ways a traditional 24 into 8 analogue console but it packs in an incredible collection of features. It has
20 channel strips: 16 dual input mono (switchable between main input or DAW return) and 4 stereo channels. The first
eight channels have VHD mic pre’s. There is an 18-slot 500-series rack built in that can be used for processing or mic
pre’s. XL-Desk ships with a legendary SSL Stereo Bus Compressor module in slots 17 & 18 (hard wired to Mix A). The rack
has its own dedicated high spec’ power supply.

There are four main Mix Buses (A, B, C, D) with buses B, C and D able to be summed into Mix A. The Buses and channels
can access the 500 rack and each have a separate insert point for processing. There are two mono aux sends and two
stereo return inputs. Direct outputs on every channel, stereo return and mix bus enable convenient stem printing. Each
channel has a Cue Stereo Bus section (with Pan and Level) used to provide one of the headphone mixes while tracking.
At mixdown the mono channel DAW return signals can be routed to the CUE ST bus and then summed into Mix A, so there
are 16 main faders + 16 Cue ST inputs + 4 Stereo channels providing 40 summing inputs (using the stereo returns and
insert Sum functions you can squeeze in over 50 summing inputs).

There is also a fully-featured monitoring section with bass management (3 sets of speakers + subwoofer), Foldback A and
B with individual talkbacks for headphone mixes and a built in Listen Mic input + classic compressor circuit, with its own
direct output.

Key Features:

• 20 + 1 fader, over 40 input SuperAnalogue™ SSL console

• 8-built in Variable Harmonic Drive (VHD) preamps

• 16 dual input mono channels (switchable between main input or DAW return)

• 4 stereo channels (switchable to mono for tracking)

• The legendary Stereo Bus Compressor, with new high-pass filter sidechain

• 18-slot 500-series rack built-in, accessible from channels or mix busses

• In addition to a 500-series rack insert each mono channel also has a standard insert point

• 4 stereo Mix Buses with their own insert points and access to the 500 rack

• One stereo and 2 mono aux sends. Two dedicated stereo return inputs

• Direct outputs on every channel, stereo return and mix bus for stem printing

• Fully-featured monitoring section with bass management

• Foldback A and B with individual talkbacks for headphone mixes

• Built in Listen Mic input + classic compressor circuit, with its own direct output

• AFL and Solo-In-Place solo modes, with Solo Clear and Solo Safe (Protect) modes

• Balanced D-Sub rear panel inputs/outputs & Front panel headphones & iJack sockets

• High quality internal PSU

Workflow

There are good reasons why so many leading engineers and producers still choose to mix on a console, some of them
because of sonic aspects and others because of workflow choices. Mixing out-of-the-box gives a wider sound-stage and
a distinct colouration that no plug-in can equal. We’re also told that it is easier to get a mix together quickly with a console
and that it feels more intuitive than a mouse. XL-Desk gives a full-featured console workflow, but with a project-studio
friendly footprint under 1m2. With 2 insert points on each mono channel you can mix and match rackmount and 500-series
processors to make the XL-Desk the hub of your hybrid studio world! Connect your XL-Desk to a patchbay for ultimate
flexibility, and use the direct outs from every channel and Bus to print files back into your DAW for easy mix revisions.

Tutorials

This manual includes a series of detailed tutorials covering different workflow which can be achieved with XL-Desk,
including the connectivity required to achieve them.

Installation Guide

INSTALLATION NOTES

Power Connection

The console is fitted with auto-sensing power supplies which will function at any voltage from 100 to 230 volts ±10%
without adjustment.

Three IEC mains power-leads may be supplied: one with a UK 3-pin fused plug fitted, one with US-style 3-pin mains plug
fitted and one with a european 3-pin plug. Please select the appropriate lead for the local power outlets.

Thermal Considerations

The console is cooled by fan-assisted convection from the front inlet (below the front buffer) to the exit in the rear panel.
It is VERY important that these ventilation grills are not obstructed in any way – particularly if the console is going to be
mounted into additional furniture.

CAUTION. The heatsink fins on the console rear panels can reach temperatures of approximately 30 degrees
Celsius above the ambient room temperature.

Rear Panel Connections

All connections to the console – apart from the headphone and iJack sockets – are located on the rear panel.

• D-Sub connectors are all high-quality 25-way female

• The screw pillars utilise the standard UNC-440 thread

• All connections are balanced and are wired to the AES59 Analogue Standard (also known as the Tascam standard)

• XLR connectors are wired with pin 2 ‘hot’

Connector Summary

* These signals also appear on the MONITOR OUTS DB25 connector

Refer to Appendix C, page 31 for connector pinout information.

D-sub to XLR Breakout Leads

When connecting directly to external equipment – amplifiers, effects units, meters etc. – adapter leads that convert the
console’s DB25 female connectors into 8 x XLRs are likely to be useful. Refer to the table on page 4 for notes on where
these adapter leads might be required.

CONNECTIVITY EXAMPLE

See diagram on page 6 for an example of how other studio equipment can be connected to XL-Desk.

USING XL-DESK WITHOUT A PATCHBAY

If using XL-Desk without an external patchbay, it is necessary to use the 4 included short D-Sub cables (shipped with XL­Desk) to link the following connections on the rear:

1 500 SEND 1-8 to 500 SLOT IN 1-8 Send from channel goes to 500 rack slot input

2 500 SLOT OUT 1-8 to 500 RETURN 1-8 500 rack slot output goes to channel return

3 500 SEND 9-16 to 500 SLOT IN 9-16 Send from channel goes to 500 rack slot input

4 500 SLOT OUT 9-16 to 500 RETURN 9-16 500 rack slot output goes to channel return

Adding these connectors will link the insert points associated with the 500 button, to and from the 500-series rack.

USING XL-DESK WITH A PATCHBAY

For ultimate flexibility, XL-Desk can connect to a standard 25-way D-Sub patchbay. One of the advantages of using a
patchbay is that it will allow patching between 500 rack modules.

The image below is a suggested layout for console connection using 4 patchrows.

Notes

1. Row AB 1–8 should be fully normalled (or could be left un-normalled – requiring the use of patchcords)

2. All other rows should be half-normalled apart form the parallels at B 41–48

3. The parallels at B 41–48 can be created by using a DB25 Mult plug

Patchbay Guidelines

Line Level Input/Outputs

All analogue inputs and outputs can be connected via a patchbay. It is recommended that the cable shield is connected
at the console end and disconnected at the patchrow to avoid ground loops. Wiring to the installation should normally
have the shield connected to the patch row. The shield connection of all jacks should be linked together (note that patch
rows with solid metal front panels will automatically do this) and then linked to a common star point on the patchbay.
This starpoint can then be returned – via a thick grounding cable (6mm sq. or greater) – to the chassis stud on the rear of
the console. This will reduce the risk of earth loops within the installation.

The screen pins of all analogue inputs and outputs – with the exception of the microphone inputs – are connected directly
to the chassis of the XL-Desk.

Mic Inputs

If Microphone inputs are to be connected via a patchbay, the type of patchrow used should be of the insulated variety
where the jack screens are not connected to the main body of the patchrow – there are commercially available patch­rows that meet this requirement. The ground connection from each microphone must be linked through the patch jacks
to the MIC INPUT 1-8 connector on the back of the console without interruption.

THE VHD PREAMPLIFIER

XL-Desk has 8 Variable Harmonic Drive preamplifiers built-in.

The red pot provides up to +75 dBs of gain, whilst the black pot provides a variable mix of 2nd to 3rd harmonics (once the
VHD button is engaged).

The outputs of these 8 preamplifiers feed the main inputs of mono channels 1-8.

VHD Engages the Variable Harmonic Drive circuit within the preamplifier
HI-Z Switches the preamplifier impedance from 1.2K  to 10K 
+48V Applies phantom power
PAD Applies 20 dBs attenuation before the signal enters the preamplifier

Using the preamplier

When the VHD button is not engaged, the preamplifier has been designed to give a transparent
sound, great for sources such as acoustic guitars, vocals and strings.

When the VHD button is pressed, the preamplifier can be driven to give a wide-range of overdriven
sounds, ranging from subtle to... well, not so subtle! Drums and electronic instruments can often
benefit from VHD colouration.

The best way to drive the VHD preamplifier is to increase the input gain (red pot) whilst using the
Line Trim pot to reduce the overall level and not clip the channel output. Remember, it’s the input
to the preamplifier that likes being driven. From this point, adjust the harmonics to fine-tune the
desired sound.

If sending pre-recorded audio back through the preamplifiers, you will find it useful to engage the
input PAD. This will lower the level at which the signal hits the preamplifier.

MONO CHANNELS

Input

Each channel of XL-Desk has two inputs, switchable by pressing the DAW button.

The primary input on channels 1-8 is the VHD microphone preamplifier. This is labelled as MIC INPUT

1-8 on the rear panel. Pressing the DAW button will instead source the line-level input labelled DAW
INPUT 1-8 on the rear panel.

The primary input on channels 9-16 is the line-level input labelled LINE INPUT 9-16 on the rear panel.
Pressing the DAW button will instead source the line-level input labelled DAW INPUT 9-16 on the
rear panel.

Typically, the outputs from your DAW’s audio interface/converter would be connected to DAW INPUT

1-8 and DAW INPUT 9-16. Some people may like to think of these as ‘monitor returns’. LINE INPUT
9-16 may be connected to outboard microphone preamplifiers (to extend the number of

preamplifiers already available) or perhaps a line-level instrument.

Remember it is possible to rescale the X-Desk’s metering to a +18dBu (as opposed to the standard +24 dBu)
with the option DIP switches on the rear panel. See DIP Switch Selection on page 28.

DAW When pressed, the input labelled DAW INPUT 1-8 or DAW INPUT 9-16 on the rear-panel is sourced.

The following buttons function on the currently selected input to the channel:

Ø Polarity inversion for the channel
500 Engages the insert point normally associated with the in-line 500-series rack slot*
INS Engages the insert point normally associated with an external piece of outboard equipment. The rear panel

connectors are labelled INSERT SEND/RETURN.

Stereo Cue and Mono Auxes

X

L-Desk has a STEREO CUE bus which can be sent to using the green level pot and panned with the blue pot. The Stereo

C

ue is switchable between pre or post-fader, on a per-channel basis using the POST button. During tracking, the Stereo

C

ue could be used for an artist’s headphone mix. For mixing, the Stereo Cue could be used to send to an FX unit for

reverb/delay.

Aux 1 and Aux 2 are mono sends, which would normally be connected to outboard FX processing like reverbs and delays.
Aux 1 is also suitable for the creation of a second headphone mix. Aux 1 and Aux 2 are globally switchable between pre
or post-fader, in the MASTER TRIMS section.

Using the ALT input button when mixing

When mixing, the STEREO CUE can source the input that is currently not selected as the main input to
the channel. This is done by pressing the ALT (alternate input) button. For example, if DAW is selected

as the main input to channel 9, then pressing ALT would bring LINE INPUT 9 into the Stereo Cue for that
channel. The green pot is used to control level whilst the blue pot positions the source within the Stereo Cue
field. Finally, the TO A button underneath the STEREO CUE MASTER TRIM can be used to inject the all signals
on the Stereo Cue bus into Mix Bus A. Using this method will provide an extra 16 inputs to the mix.

Pan Pot, Mix Bus Assignments, CUT, SOLO and Faders

At the base of XL-Desk you will find traditional analogue desk functions.

The blue PAN pot controls the channel’s left/right positioning in the stereo field when assigned to one
or more stereo mix bus.

A B C D buttons will route the channel to the relevant stereo mix bus: Mix A, Mix B, Mix C, Mix D.
CUT mutes the channel’s output.

SOLO - The exact action of the solo is dependant on the desk’s current solo mode: Solo-in-place

(SIP) or AFL (After-Fader-Listen). See page 17 for additional information.

The space below the SOLO button provides enough room to stick the traditional strip of electrical tape
to write track names on.

The 100mm analogue fader provides a gain control for feeding the selected stereo busses and/or direct
channel output if CHOP POST is selected.

Page 12 XL-Desk – Owner’s Manual

STEREO CHANNELS

X

L-Desk provides 4 stereo input channels located immediately to the left

o

f the Mix A master bus fader.

The stereo channels on XL-Desk differ from the mono in the following ways:

•

Stereo channels have one stereo input per strip

• Two signal present LEDs are provided for monitoring incoming left
a

nd right signals

• No insert points

• The pan pot becomes a balance pot when operating in stereo.

Each stereo channel can operate in mono by pressing the MONO button
next to the pan pot. This is useful for heavy tracking sessions, where you
need extra mono inputs to feed these channels – the outputs from extra
preamplifiers, for example.

XL-Desk – Owner’s Manual Page 13

500-SERIES RACK

Slots 1–16

Built into the penthouse of XL-Desk is a 500-series rack. This rack is a 16 + 2 slot design. The image shows the
rack filled with SSL modules – but of course, this could be a selection of 500-series modules from other
manufacturers. The first 16 slots are lined up with the 16 mono channels, and pressing the button labelled 500
will activate the insert return, bringing the 500-series processing into that channel...

Slots 9–16

...However, the 4 stereo mix busses (A B C D) are able to steal rack slots 9-16 to use as extra processing:

Mix A can steal 500 slots 9–10
Mix B can steal 500 slots 11–12
Mix C can steal 500 slots 13–14
Mix D can steal 500 slots 15–16

The slots are stolen by pressing the 500 button in the master controls section for each mix bus. See the following section
for more information.

or 500-series modules that support the ability to link sidechains across

o

dd/even module slots, every odd numbered rack slot has a jumper on the

r

ack’s backplane that can be moved from position ‘A’ (Not Linked), to position

‘

B’ (Linked Sidechain).

NOTE. To gain access to these links, you will need to remove the
module (and any adjacent ones that make changing this awkward).
Please ensure that the POWER TO THE CONSOLE IS OFF.

Slots 17-18

The final two slots are reserved for the legendary SSL Bus Compressor. These slots can only be inserted over the Mix A
stereo bus by pressing the COMP button in the Mix A master controls section.

Don’t forget that this is just a standard two-slot 500 rack space, so you can remove the Bus Compressor and use it
anywhere else in the rack if desired or use a different 500-module in place of the Bus Compressor!

Using the 500-series Rack With or Without a Patchbay

The rear panel of XL-Desk allows access to the inputs and outputs of the 500-series rack. These D-Subs are labelled: 500
SLOT IN 1-8, 500 SLOT IN 9-16, 500 SLOT OUT 1-8 and 500 SLOT OUT 9-16.

If using XL-Desk without an external patchbay, it is necessary to use the 4 included short D-Sub cables (shipped with XL­Desk) to link connections on the rear. Refer to the additional information on page 7.

For ultimate flexibility, remove the short D-Sub patch cables and link those connectors discretely to a patchbay. This will
allow routing to be made between modules, so that more than one 500 processor slot can be used on a single channel.

The thing to remember is that the 500button is, in reality, a second insert point which can route the signal
out of and back into the channel. By connecting the short D-Sub patch cables, as described on page 7, the
signal is routed into the associated 500-series rack slot and back again – e.g. Channel 1’s 500 button
inserts Slot 1 from the 500 rack.

XL-Desk – Owner’s Manual Page 15

Bus Compressor

I

ncluded with every XL-Desk is the legendary SSL Bus Compressor for 500-series. It is a simple

u

nit with a simple purpose; it makes complete mixes sound bigger, with more power, punch

a

nd drive. It brings cohesion and strength to your mix without compromising clarity. The

u

pdated design now includes a notched high-pass filter in the sidechain.

The compressor sidechain controls are straight-forward and hopefully require little
explanation. The ATTACK, RATIO and RELEASE and HPF (High Pass Filter) controls are multi­position switches; the THRESHOLD and MAKE-UP controls are continuously variable
potentiometers. The illuminated compression meter above the unit displays gain reduction
for the compressor.

Page 16 XL-Desk – Owner’s Manual

CENTRE SECTION

Stereo Returns

Traditionally, Stereo Returns are usually fed from the outputs of FX units such as Reverbs and Delays.
They could, however be used as extra inputs for any line-level signal.

XL-Desk has 2 Stereo Return inputs each with its own blue balance pot and black level control.

S

T CUE Routes the stereo return to the Stereo Cue bus.
MONO Creates a mono sum of any signals present. The balance pot becomes a left-right pan.
A B C D Routes the Stereo Return signal to any selection of stereo busses.
A

FL Allows the stereo return to be auditioned in the studio monitors.

Remember to turn the AFL master pot up in the monitoring section first!

Master Trims

This section provides useful level trim controls.

The green ST CUE level pot provides up to +10dBs of gain for the Stereo Cue bus. This pot is centre-indented at
0dB. AFL allows the Stereo Cue bus to be auditioned in the studio monitors.

The green AUX 1 level pot provides up to +10dBs of gain for the Aux 1 bus. This pot is centre-indented
at 0dB. PRE globally sets Aux 1 sends be pre-fader. AFL allows the Aux 1 bus to be auditioned in the
studio monitors.

The green AUX 2 level pot provides up to +10dBs of gain for the Aux 2 bus. This pot is centre-indented
at 0dB. PRE globally sets Aux 2 sends be pre-fader. AFL allows the Aux 2 bus to be auditioned in the
studio monitors.

Mix B, Mix C, Mix D Master Controls

3 of the XL-Desk’s 4 stereo mix busses are controlled in this section. The controls that apply to Mix B, C and D are identical.

Mix Busses B, C and D do not have dedicated 500-series rack slots associated with them. However, by pressing the 500
button, XL-Desk allows each Mix Bus to ‘steal’ a pair of slots from the rack:

Mix B – Pressing 500 allows Mix B to steal 500-series rack slots 11-12
Mix C – Pressing 500 allows Mix C to steal 500-series rack slots 13-14
Mix D – Pressing 500 allows Mix D to steal 500-series rack slots 15-16

This way, processing modules inserted into the 500-series rack can be swapped between use on mono channels or stereo
mix busses. (For additional information see diagram on page 13.)

When a pair of 500-series rack slots are stolen, they are unavailable for use on the mono channels they are
normally associated with. They can be released back to these by simply pressing the 500 button again.

INS engages the insert point normally associated with an external piece of stereo outboard equipment. The
rear panel connectors are labelled MIX A B C D SEND and MIX A B C D RETURN.

The SUM button, below the INS button, sums the Insert Return and the original Mix Bus feed together providing
a direct stereo input to the Mix bus. This also provides a clever way of ‘instant parallel compression’ if using
an outboard compressor. Use the output gain of the compressor to control the level of compressed signal.

TO A routes the output of the mix bus into Mix A.

The black pot controls the overall level of the mix bus. This pot is centre indented at unity gain. At full clockwise
rotation +10dBs of gain is provided.

AFL allows the Mix Bus to be auditioned in the studio monitors.

XL-Desk – Owner’s Manual Page 17

Mix A Master Controls

T

ypically, the output of Mix A would be used as the final stereo output from which the final mix would be

p

rinted back into the DAW.

Mix A has its own dedicated 100mm heavy-duty fader, with 0dB gain at the very top of the fader travel. In
addition, the following buttons can be found above the MIX A fader:

The 500 button allows Mix A to steal processing slots 9 -10 of the 500-series rack.

INS engages the insert point normally associated with an external piece of stereo outboard equipment.
The rear panel connectors are labelled MIX A B C D SEND and MIX A B C D RETURN.

The SUM button below the INS button, sums the Insert Return and the original Mix Bus feed together
providing a direct stereo input to the Mix bus. This also provides a clever way of ‘instant parallel
compression’ if using an outboard compressor. Use the output gain of the compressor to control the level
of compressed signal.

The button labelled COMP engages the in-built SSL Bus Compressor. In true SSL tradition, the send is always
active, so be sure that both the COMP button and the IN button on the compressor itself are active, as the
compression needle will be moving regardless of whether it is in circuit or not.

Solo Master Section

CLEAR - Cancels any solos

SAFE - Enters/exits Solo Safe setup mode. This is useful when you want

to protect channels from being cut when a solo is made.

A prime example would be a vocal reverb return.
This presumes you are in Solo-In-Place mode.
Imagine a dry vocal is routed into channel 8 of the
desk. From this, Aux 1 is being used to send
signal into an outboard reverb unit. The output of
this reverb unit is being sent into channel 23­24(stereo fader). The desired effect is that when
channel 8 is solo’d, channel 23-24 is not cut and
the listener ‘automatically’ hears the reverb
return without needing to pressing the solo
button on channels 23-24.

AFL - When this button is lit, the desk operates in
After-Fader-Listen (AFL) solo mode.

To Solo Safe channels do the following:

1. Press the SAFE button to enter the setup mode

2. Press the SOLO button on desired channels (they flash)

3. Press the SAFE button to exit this setup mode.
Now, these channels are not cut when a solo is made.

To remove channels from Solo Safe mode do the following:

1. Press the SAFE button to enter setup mode.

2. Any channels that are Solo Safe’d will flash their SOLO

buttons

3. Press any flashing SOLO buttons to remove them from

Solo Safe mode

4. Press the SAFE button to exit.

The difference between Solo-In-Place (SIP) and After-Fader-Listen (AFL) solo modes:

SIP – XL-Desk’s default soloing mode. When a solo is made, all other channels are CUT.

AFL – Press the AFL button to switch XL-Desk into AFL solo mode. When a solo is made, the signal(s) is sent to the AFL bus. The

monitoring section will automatically source the AFL bus if a solo is made in this mode. Ensure the AFL bus master level
control is turned up. AFL may be useful when recording/printing stems because soloing a channel does not cause other
channels to CUT.

Page 18 XL-Desk – Owner’s Manual

Monitoring Section

X

L-Desk features a comprehensive professional monitoring section.

MONITOR LEVEL - Controls the monitoring volume.
DIM button - Attenuates the monitoring volume.
C

UT button - Mutes the monitoring path.
DIM control - Sets the level of attenuation applied by the DIM button.
AFL control - Sets the level of the AFL bus.

Mon Select

XL-Desk allows up to three pairs of stereo monitor speakers to be connected, as well as a dedicated sub
speaker.

MONO sends the summed Left and Right Stereo signal to both monitor speakers.
MINI 2 selects the speaker set connected to the MINI 2 monitor outputs.

This speaker set can be setup to work in mono – for use with a single “grotbox” for instance.
(See OPTION DIP SWITCHES section on page 28.)

MINI 1 selects the speaker set connected to the MINI 1 monitor outputs.
SUB engages bass management for the selected monitor speaker set. When SUB is lit, the bass management

sums left and right signals through a 3rd order low-pass (high cut) filter at 80Hz and sends the sum out of
the Sub monitor output. Also, 2nd order high-pass (low cut) filters are inserted into the selected left and right
monitor outputs.

Did you know… The bass management on XL-Desk is intelligent. It will remember if the SUB
button is on or off for each speaker set!

Mon Source

MIX A selects Mix A as the source for the monitoring.
EXT selects the rear panel External Input as the source for monitoring.
iJack selects the front panel mini-jack (⅛ inch) socket as the source for monitoring.
SUM allows any selection of monitor sources to be selected at once and sums them into the monitoring path.

H/P

The black level pot controls volume for headphones connected to the front panel ¼ inch jack socket.
With neither F/B A or F/B B selected, the headphones source whatever is currently selected in the MON SOURCE

section (MIX A, EXT, iJACK).
Pressing F/B A (or F/B B) allows the front panel headphones to audition Foldback A (or B) – useful for checking

the performer’s headphone mixes.

Please be aware that when sourcing F/B A or F/B B in the front-panel headphones, the talkback signal will
not be heard.

XL-Desk – Owner’s Manual Page 19

Foldback

X

L-Desk has 2 in-built Foldback circuits. In a recording situation, foldback circuits are used to provide performers with
i

ndividual headphone mixes with talkback. Typically, the foldback outputs on the rear ox XL-Desk are plugged into

h

eadphone amplifiers in the studio live room.

FOLDBACK A (ST CUE) - The black level pot controls the overall level of foldback. This
foldback circuit picks up the Stereo Cue bus. TALK A activates the front panel talkback
mic and sends it to Foldback A.

FOLDBACK B (AUX 1) - The black level pot controls the overall level of foldback. This
foldback circuit picks up the Aux1 bus. TALK B activates the front panel talkback mic
and sends it to Foldback B.

The MON buttons below each foldback’s black level control override the default foldback source (Stereo Cue or Aux 1)
and replace it with whatever is selected in the MON SOURCE selection. This is really useful for quickly playing back the
studio control room mix to the performer(s) in the live room.

IMPORTANT – Please be aware that pressing the MON buttons may cause a significant increase in the level sent to the
foldback headphone amps. This is because control room sources are likely to be significantly louder than CUE/AUX 1
levels. You may need to reduce the overall foldback level before pressing MON. Alternatively, increase the CUE/AUX 1
master trim level beforehand to match levels, with and without the MON buttons pressed.

The OPTION DIP SWITCHES on the rear panel allow the TALK buttons to be configured as latching or
momentary. Also, talkback can be set to either SUM with or REPLACE the existing signal. (See page 28 for DIP

switch settings.)

LISTEN allows the engineer to monitor the incoming Listen microphone signal. The listen microphone is typically
set up somewhere near the middle of the live room. (The LISTEN INPUT to XL-Desk is found on the rear panel as a

female XLR connection.)

The black TALK control sets the gain of the in-built front panel talkback

microphone.

The black LISTEN control sets the gain of the Listen microphone input preamplifier.

Bargraph Metering

The top-right of the penthouse hosts 20-segment peak metering for
XL-Desks 4 stereo mix busses. The metering of XL-Desk can be globally
switched between +24dBu and +18dBu scales via the rear panel
OPTION DIP SWITCHES.

HOW TO TRACK WITH XL-DESK

T

here are many different ways in which XL-Desk can be used to record music. If you’re looking for some “tried and tested”

i

ndustry techniques from the pro’s on how best to operate this desk, then please read on.

Example 1 - Recording a small ensemble in a ‘split’ console style.

L

et’s assume we are recording a small group, that requires no more than 8 microphones to be setup in the live room. For

e

xample, a Jazz Trio may involve the following setup:

Input List

1 Kick Drum Microphone
2

Snare Drum Microphone
3 Overhead Left Microphone
4 Double Bass Microphone
5 Guitar Microphone
6 Vocal Microphone
7 Room Left Microphone
8 Room Right Microphone

Split Recording

We’re going to treat XL-Desk like a ‘split’
console. This means that the first 8
channels will be our inputs and channels
9-16 will be our DAW returns. We will be
treating Mix B as a “record bus” (a bus
which the input recording channels are
routed to) and Mix A as the “mixing bus”
(a bus to which the DAW returns are
monitored and mixed).

1) Plug 8 microphones into MIC INPUT 1-8 of XL-Desk. (Using the DB25 to 8

XLR female interface lead, where necessary.)

2) Set channels 1 to 8 of XL-Desk to source from the microphone inputs

(DAW button is not pressed)

3) Increase the gain (red control) on the microphone preamplifiers until
the tri-colour LED starts to show some signal. If the microphone needs
phantom power, use the +48V button.

4) It’s probably a good idea to listen to how the microphones are
sounding. To do this route the first 8 channels to Mix Bus B by pressing
the B routing button above the CUT buttons. Raise the faders.

5) Make sure the MIX B master level control is at 0dB in the centre section
(centre-indented position). Press the MIX B AFL button and raise the
MONITOR LEVEL control to hear your inputs through the speakers.

XL-Desk – Owner’s Manual Page 21

6) At this point as the engineer you have some decisions to make as to how you
want to record. The direct channel output (CHOP) can be set post-fader or pre­fader using the CHOP POST button. You can process the input recording
channels using external rack gear connected to the insert points (INS button)
or the 500-series rack slots (500 button).

7) Set up 8 tracks in your DAW session to record the 8
microphone signals. This tutorial assumes that the
first 8 direct channel outputs have been connected
to the first 8 inputs of your DAW’s audio interface.

8) In your DAW record arm the 8 channels for
recording. Route the outputs of these tracks into
DAW INPUT 9-16 on XL-Desk.

9) Press the DAW button for channels 9-16 and
you will see signal coming into the desk.
Route these channels to Mix Bus A using
the A routing button (above the CUT
button).

Ensure that the MIX A master fader is
raised and that MON SOURCE is set to
MIX A.

Don’t forget to un-select the Mix Bus B AFL button when you want to hear the DAW returns. At any point, you
can choose whether you’re listening to the input signals on Mix B or the DAW returns on Mix A by simply
toggling the Mix B AFL button on or off.

Example 2 - Recording a Full Band and Monitoring Back Via Stems

L

et’s assume that a band are coming into the studio to record and the input list looks as follows:

Input List

1 Kick Drum Inside Microphone 9 Room Left Microphone
2

Kick Drum Outside Microphone 10 Room Right Microphone

3

Snare Drum Top Microphone 11 Bass DI

6

Floor Tom Microphone 14 Lead Electric Guitar Microphone
7 Overhead Left Microphone 15 Backing Vocal
8 Overhead Right Microphone 16 Lead Vocal

For this recording, you have decided that
a click track will be necessary.

1) Plug the first 8 microphones into MIC INPUT 1-8 of XL-Desk (all the drums).

(Using the DB25 to 8 XLR female interface lead.)

2) Use external preamplifiers for inputs 9 -16. Plug the outputs
of the preamplifiers into LINE INPUT 9-16. (If using your own

500-series amps, see notes on page 25.)

3) Make sure channels 1-16 are NOT sourcing from the DAW input. (The DAW button

should be released.)

4) Increase the gain (red control) on the microphone preamplifiers until
the tri-colour LED starts to show some signal. If the microphone needs
phantom power, use the +48V button. Repeat this process for your
outboard preamplifiers.

Tip: Engage the VHD button on the drum preamplifiers to add crunchy
harmonics and liven up the drum sound. Use the gain (red control)
to drive the signal and the TRIM to back off the overall output level.

5) It’s probably a good idea to listen to how the microphones are sounding.
To do this route the first 16 channels to Mix Bus B by pressing the B
routing button above the CUT button. Raise the faders.

6) Make sure the MIX B master level control is at 0dB in the centre section
(centre-indented position). Press the MIX B AFL button and raise the
MONITOR LEVEL control to hear your inputs through the speakers.

9) In your DAW record-arm 16 tracks for recording. Next, create 3 sub-groups – Drums, Guitars and Vocals. Finally, insert
a click track.

10) Route the sub-groups out of the DAW into the stereo channels of XL-Desk. Route the click track into
the final stereo input on XL-Desk and press the MONO button. Route these channels to Mix Bus A using
the A routing button above the CUT button.

Ensure that the MIX A master fader is raised and that MON SOURCE is set to MIX A.

Don’t forget to un-select the Mix Bus B AFL button when you want to hear the DAW returns.
At any point, you can choose whether you’re listening to the input signals on Mix B or the
DAW returns on Mix A by simply toggling the Mix B AFL button on or off.

With a session such as this you are likely to want to create some headphone mixes for the performers. Please read the

Creating Headphone Mixes for Tracking

H

ere is a useful example of how to create headphone mixes during tracking. XL-Desk provides two foldback circuits.

F

oldback A is fed by the STEREO CUE bus and talkback can be injected using the TALK A button. Foldback B is fed by the

A

UX 1 bus and talkback can be injected using the TALK B button.

This example presumes that you have the Foldback A
and Foldback B outputs from XL-Desk feeding
independent headphones amps in the live room.

1. Set the Stereo Cue on each channel to be pre-fader. Use the Stereo Cue level and pan pots across
the channels to create a mix for the first performer.

2. Turn up the Foldback A level master in the centre section until the performer can hear the mix at a
desirable level (insert drummer joke here…)

TIP: The front panel headphones socket can be sourced from Foldback A (FB A) or Foldback B
(FB B) by pressing the appropriate front panel button. This is a useful way of auditioning the
mix that has been created for the performer in the live room.

3. Turn the TALK pot up to an appropriate level. Pressing TALK A activates the built-in talkback
microphone so you can communicate with the first performer.

To set up the second headphone mix, repeat the process but this time using Aux 1
(globally set to pre-fader), to create a mono mix for the second performer. Turn up
Foldback B level master to the desired level and use TALK B to activate talkback.

Aux 2 can be used to create a headphone mix without talkback, or perhaps as a mono send to a reverb
unit.

Using 500-series Rack Slots 9-16 with Microphone Preampliers

Y

ou may already own 500-series microphone preamplifier modules and

w

ish to use these with XL-Desk. You can fill 500-series rack slots 9-16

w

ith microphone preamplifier modules and use them by doing the

f

ollowing:

1) Plug the microphone(s) into the microphone preamplifier
module(s). If it does not have a front panel XLR then connect via
XL-Desk’s rear panel connector labelled 500 SLOT IN 9-16.

2) Press the channel’s 500 button. This will bring the signal into the
channel (presuming that the rear connector labelled 500 SLOT OUT
9-16 is connected to 500 RETURN 9-16).

3) Use the channel direct outputs to record signal into the DAW.

5 - Configuration

Adjusting the Level of MINI 1 and MINI 2 Monitor Outputs

Speaker sets often require level trimming to allow a consistent listening level when switching between different sets. XL­Desk allows the MINI 1 and MINI 2 monitor outputs to be adjusted in 0.5dB steps.

T

o adjust a MINI speaker set:

1) Press and hold the MINI 1 button for three seconds. Upon entering this mode the MIX A bargraph meter
will change to make clear you have entered the setup mode correctly.

2) Press DIM to attenuate in 0.5 dB steps, press CUT to increase gain in 0.5 dB steps.

Adjust until the desired result is achieved.

3) Press the MINI 1 button again to exit the setup mode and return to normal operation.

To adjust MINI 2, repeat the process but replace MINI 1 button presses with MINI 2 button presses.
