X-Rack Installation and O eration
3. X-Rack Installation
3.1 Assembling the X-Rack
The X-Rack unit is normally shipped either as an empty rack (SSL Part No. 729935X1), a part filled (custom)
rack or as a fully loaded unit; for example, a unit fitted with eight 729618X1 Dynamics modules (SSL
Part No. 729935X2) – if you have purchased a fully loaded unit you should skip the rest of Section 3.1.
In the case of empty or part filled racks, any empty module slots will be covered by blank panels which
will need to be removed before fitting additional modules. Panels for module slots and the Total
Recall/CPU are secured, top and bottom, by a ‘one piece’ floating threaded bar. The position of the bar is
factory set so that there is adequate space to accommodate eight module panels. The correct position of the
threaded bars is initially set when the Total Recall/CPU module is installed and screwed in position
against the inside right edge of the rack.
Do not attempt to fit or remove modules with power applied. Always switch the rack off and remove the power
cord prior to working on this unit. When fitting or removing modules, it is advisable to observe suitable ESD
precautions. ake care when handling modules and blank panels; sharp corners may be present.
Modules are fitted from the front of the X-Rack, normally starting from the left hand end. Note that it is
recommended that any required blank panels (SSL Part No. 729618X2) are fitted prior to fitting modules.
Each module plugs into the backplane; use the two 8mm M3 counter sunk screws supplied with the
module or blank to fix the item to the front of the rack – a 2mm AF hex key is supplied with the X-Rack
unit. The rear connector panel or blank should be screwed to the rear of the case using the two 8mm M3
button head screws supplied with the module. The end result should be a unit that is fully loaded with
modules and/or blank panels. For ease of fitting, do not tighten the screws until all modules and/or blank
panels have been fitted.
o ensure peak operating performance, please ensure all front and rear panel fixing screws are securely
tightened; slight warping on the rear of the chassis may be observed – this is no cause for concern.
enerally, any module may be fitted in any position but with the following provisos:
• To use the Dynamics Link function, Dynamics modules must be placed in adjacent slots.
• The Dynamics Link function should only be used with similar types of Dynamics module!
• Only one Master module should be fitted in any one X-Rack.
• When fitting a Master module to X-Rack serial no. XRK0110 or earlier, the module should be fitted
immediately to the right of any modules which use either the Mix, Record or Solo/AFL Buses. This
limitation does not apply to later X-Rack units.
3.2 Mounting
The X-Rack unit is designed to be rack mounted or free standing. It is 4RU (178mm/7 inches) high. Its
depth is:
• 180 mm/7.2 inches
• 255 mm/10.2 inches including connectors
The unit does not require rack shelves. A 1RU space should normally be provided above the unit.
The unit is supplied fitted with both feet and rack ears. If the unit is to be rack mounted the feet should be
removed using the supplied 2.5 mm AF hex driver. The same driver can be used to remove the rack ears
if the unit is to be free standing.
Feet and rack ears are fixed using M4 x 8mm screws – do not replace them with longer screws as this may
damage the rack electronics.

Page 6
X-Rack Owner’s Manual
3.3 Connection
3.3.1 ower Connection
The X-Rack unit has an auto-sensing power supply that can operate on 100 – 230V without adjustment.
The power connection is made via a standard IEC mains cord to an un-switched IEC mains socket on the
rear panel and a latching power switch is provided on the front panel of the unit.
3.3.2 Audio Connection
enerally, each module will have an input connector (normally a female XLR) and an output connector
(normally a male XLR). Depending upon the type of module other connectors, such as key inputs, may be
present also. Connect the module inputs to the insert sends of your console or to your workstation outputs.
Connect the module outputs to the corresponding insert returns or to your workstation inputs.
Once the unit is connected switch it on, then route a signal to each channel in turn and check that it is
returned to the correct input on your console or workstation.
Some module input and output gains can be set to operate at a nominal level of +4dBu or –10dBV using a
switch on the connector panel. Select the appropriate level for the equipment you are connecting to. If in
doubt either refer to the section of this manual specific to the particular module or experiment!
3.3.3 Connection to an AWS or Matrix Console
If the X-Rack is being used with an AWS console, connect the
TOTAL RECALL LINK IN connector (a 9 pin D-type) to Serial
Port 1 on the conole’s connector panel using the supplied 2
metre cable. If connecting to a Matrix console, connect the cable
to the X-RACK/DIAG connector. For either console, this cable
may be extended to a maximum of 15 metres using a suitable
pin to pin extension cable.
If you have more than one X-Rack unit connect the
TOTAL RECALL LINK IN connector on the second unit to the
TOTAL RECALL LINK OUT connector on the first unit using
the supplied cable. Further units may be connected in the same
manner up to a maximum of four (AWS) or six units (Matrix).
3.3.4 MIDI Connection
The MIDI port can be used for several functions:
• Archiving of the 32 internal stores as SysEx (System Exclusive) dumps
• Remote control of the ‘soft’ functions of the XR622 Master module
• Updating the system software
If you wish to use this facility connect the X-Rack MIDI IN connector to a spare MIDI out connector on
your MIDI interface and the X-Rack MIDI OUT connector to the corresponding MIDI input.
A separate connection is required for each X-Rack.
3.3.5 Mix Bus Link
Some X-Rack modules can route signals onto the X-Rack’s internal mix busses. This 25-way ‘D’ type
connector is provided to enable access to these buses and, using this connector, multiple X-Racks may be
connected together enabling a large stereo mix system to be constructed. The pinout for this connector is
detailed in Section 5.2.

4. Operation – Total Recall
4.1 Overview
The Total Recall computer stores all of the switch and rotary control
positions for each X-Rack module in one of thirty two internal stores.
These can be recalled and compared with the current settings using
front panel LEDs to show which controls do not match. If the module
layout has changed since the snapshot was taken, only the modules
that match will be recalled.
The contents of all the stores can be archived and restored as a MIDI
system exclusive data dump.
Additionally, the X-Rack can interface with the Total Recall system on
AWS 900, AWS 900+, AWS 924, AWS 948 or Matrix consoles. This
allows the settings of up to four (AWS) or six (Matrix) X-Rack units to
be stored along with the console settings.
4.2 Stand-alone Mode
4.2.1 Saving Stores to Internal Memory
A maximum of 32 stores can be saved in internal non-volatile memory, provided the stores have not been
write-protected – indicated by the ‘Wr rot’ LED being illuminated.
First select a store by turning the D-Pot , then press SAVE to
store all of the current control positions.
If the store has already been used the SAVE LED will flash. Press the
SAVE switch a second time to overwrite the store.
4.2.2 Recalling and Displaying Stores
To select a store using the D-Pot then press the D-Pot to select that store.
The current store is displayed on the dual 7-segment display .
If the selected store is empty the ‘Empty’ LED lights and the unit will not switch to display mode.
With a valid store selected, the X-Rack module SEL LEDs will light if the module type in the store (EQ,
Dynamics etc.) matches the module currently fitted in that slot. A flashing SEL LED indicates that some controls
on that module do not match the stored positions. A steady LED shows that all controls are matched. The
switch LEDs will light if the current switch position does not match the stored positions. Press or release
the switch as required to extinguish the LED.
Above each rotary control is a bi-colour LED:
The LED extinguishes when the control matches the stored position.
If a store is already being displayed when you select a different store the display will flash and the new
store will not become active until you press the D-Pot for a second time.
4.2.3 Exiting Display Mode
Push the D-Pot a second time to exit display mode.
All SEL LEDs will extinguish and the channel switch LEDs will now show the position of their respective
switches.

4.3.1 System Requirements
The X-Rack ‘TOTAL RECALL LINK IN’ connector must be connected either to AWS serial port 1 or the
X-RACK/DIA connector on Matrix using the pin-to-pin serial lead supplied with X-Rack – see Section
3.3 for more details. If more than one X-Rack is connected each X-Rack must have a different address – refer
to the Setup/MIDI Mode Section.
An AWS 900 must be running V1.2/6 or higher software and have otal Recall enabled for this to function.
Current AWS 900 software can be downloaded from the SSL website.
4.3.2 Operation
Pressing the Total Recall STORE switch on the console will send a message to all attached X-Racks asking
for the current control settings to be returned. The returned settings are appended to the console’s Total
Recall stores and are automatically archived and restored as part of the console Total Recall system.
Similarly, displaying a Total Recall setup on the console will return the selected Total Recall setup to the X-
Rack unit(s). The remote load command will always replace the current setup and the X-Rack display will
read ‘re’.
To display the new settings, press the D-Pot as in ‘Stand-alone’ mode and to exit display mode press the
D-Pot a second time. If the console store does not contain valid data (for example if it was saved on a
console not connected to an X-Rack) the ‘Empty’ LED will light and it will not be possible to select display
mode.
Settings can be saved to X-Rack’s local store and recalled at any time by turning the D-Pot (though see the
Remote option in the Setup menu section). Storing the Total Recall settings on the console will always save
the current state of the X-Rack and displaying a Total Recall setup will replace the store to be displayed
with the store from the console.
See the Remote and the Address options in the Setup/MIDI Mode Section.

4.4.1 Overview
Enter SETUP/MIDI mode by holding down SETU /MIDI until the
display reads ‘5e’. The SETU /MIDI LED flashes to show you are in
this mode. Press and hold the same switch to return to normal
operation.
Navigating in the Setup menu
The setup menu contains a number of options. These each contain a number of sub-options. Turn the
D-Pot to scroll through the main list of options and push the D-Pot to select an option for editing. The D-
Pot will now scroll through the available list of possible settings for that option. Pressing the D-Pot again
will save the currently selected setting and return to the normal option menu. The options are:

4.4.2 MIDI (m1)
Under this menu it is possible to set the MIDI controls which can control parts of the X-Rack XR622 Master
module and also to save and load all internal stores to and from a MIDI sequencer or librarian as a SysEx
dump.
MIDI Remote Channel (ck)
Under the MIDI menu, use the D-Pot to select MIDI Channel.
Then press the D-Pot and turn it to select the required channel (‘01’
to ‘16’ or ‘al’ for all/any channel). This is the MIDI channel that
will be used for remote control of the XR622 Master module.
By default X-Rack will listen on all channels.
MIDI Remote Learn (le)
Under the MIDI menu, use the D-Pot to select
MIDI Learn (le) and press SAVE. The green
‘Wr rot’ LED will flash to indicate you are in MIDI
Learn mode. Operating any one of the ‘soft’ controls
on the XR622 Master module will cause the LED of
the selected control to flash (the module ‘SEL’ LED
will flash if either of the potentiomenters have been chosen) – indicating it has been chosen. Assign a MIDI
controller to the selected function by operating the required MIDI controller. To cancel or change the
assignment either operate the Master module control again, or operate a different control. A successful
assignment will be indicated by the flashing LED changing to just being illuminated steadily.
Only single controls can be mapped to a MIDI controller. herefore, mapping an X-Rack control to a MIDI
controller which is already in use will remove the previous mapping. he original X-Rack control will require
re-mapping itself before it can be controlled again.
To exit MIDI Learn mode, press the D-Pot – the green ‘Wr rot’ LED will stop flashing. Switch assignments
can be reset to the system defaults by pressing CO Y/DEL when in MIDI Remote Learn mode; the ‘Empty’
LED indicating when the assignments have been deleted.
MIDI Save and Load
In order to use the MIDI save and load utility the X-Rack must be connected to a computer running a
suitable sequencer or MIDI librarian package.
All the stored setups can be saved as a System Exclusive dump to any software package that supports
MIDI SysEx dumps. In practice this includes most packages and you would normally save the TR setups
to an additional track in your current DAW project so that your setups are stored with the rest of the
project.

Saving Setups to a Mac or C (sa)
With the X-Rack in Setup Mode, saving TR setups to Mac or PC can be achieved as follows:
• Under the MIDI menu, use the D-Pot to select MIDI Save.
• The display will show ‘5a’ and both the ‘SAVE’ LED and display flash.
• Create an additional MIDI track in your DAW program. Select its input and output to be the MIDI
port connected to your X-Rack.
• If available select the track to store System Exclusive data and record enable the MIDI track.
• Press Play and Record on the DAW to put the MIDI track into record.
• Press the SAVE switch to start transmission of all saved Total Recall setups.
A ‘rotatingsegment’ display will start and run until all data has been transmitted
• Once the display changes to ‘m1’ stop the DAW to end recording.
An unlimited number of Total Recall setups can be stored in this way.
Loading Setups from a Mac or C (l0)
Restoring setups from a Mac or PC is even simpler:
• Enter MIDI mode as before, and turn the D-Pot until the display
changes to ‘l0’ and begins to flash.
• Locate the DAW to just before the SysEx data containing the setups you wish to load.
• Play through the SysEx block of data. The display will show a rotating segment while data is received.
As soon as the X-Rack detects the start of valid data it will delete all the current setups and replace
them with the stored ones from the MIDI track.
4.4.3 Write rotect Mode (pr)
Write Protect prevents existing stores being over
written or deleted, providing an extra level of
protection for units that have been programmed
with particular settings.
When set to ‘0n’ the Save and Delete functions are
disabled. When set to ‘0f’ they are enabled. The
‘Wr rot’ LED lights to show this mode has been
selected.
4.4.4 Remote Mode (re)
This mode enables remote
control of X-Rack, either from a
console for saving and recalling
Total Recall snapshots or from a
MIDI controller for control of the XR622 Master module.
When Remote Mode is ‘0n’, selecting a TR setup on the console will change the current X-Rack setup to
the one saved in the console. The X-Rack display will change to read ‘re’ (remote) and pressing the D-Pot
will display the TR setup as normal. When Remote Mode is ‘0f’, turning the D-Pot will change the current

X-Rack setup to one of the internal stores but when Remote Mode is set to ‘0n’ the D-Pot is disabled once
the X-Rack has received a setup from the console. This also prevents saving or deleting of local stores.
When Remote Mode is set to MIDI (‘m1’), the ‘soft’ controls on the XR622 Master module may be remotely
operated as MIDI controls. The Master module controls will continue to function until a valid MIDI packet
has been received, after which all of the ‘soft’ controls will be locked out – this condition will be indicated
by illumination of the right-hand decimal point in the X-Rack display. Which MIDI channels and controls
are used is set through the MIDI learn process (see above).
Setting Remote Mode to MIDI will disable the console otal Recall connection.
4.4.5 Address Setting (ad)
If more than one X-Rack is to be connected to an AWS 900 then each must have a different address. Enter
Address mode and turn the D-Pot so the display reads ‘a1’, ‘a2’, ‘a3’ or ‘a4’ then press the D-Pot to save
the address:
The order of addressing is not important, but we recommend you address the racks in the order they are
connected to the AWS 900. This will increase the chances of data being correctly mapped if you move to a
different facility.
4.4.6 Record/Mix (rm)
This function is applicable only to X-Rack units fitted with one or more XR623 Line Return module(s). The
‘rm’ setting allows the REC switches on these modules to opperate in either ‘Alternate’ mode where the
switches flip between the Record and Mix busses or ‘Sum’ mode where the Mix bus is permanently fed
with signal routed to the Record bus only when the REC switch is pressed.
Select Record/Mix by turning the D-Pot till the display shows ‘rm’.
To select ‘Alternate’, turn the D-Pot to show ‘al’ then press the D-Pot to set it.
To select ‘Sum’, turn the D-Pot to show ‘su’ then press the D-Pot to set it.
4.4.7 Show Version (ve)
Select Show Version by turning the D-Pot till the display shows ‘ve’.
Press the D-Pot to show the software version
in three blocks. As an example, software
version ‘V1.3/1’ will display in this sequence
before returning to display ‘ve’.

4.4.8 Test Mode (te)
This mode is used for testing the front panel switches and LEDs.
There are three test modes available, selected using the D-Pot as for the other Setup functions:
Test LEDs (tl)
This toggles the bi-colour LEDs above the pots between red and green.
Test Switches (t5)
This mode flashes all the channel switch LEDs. Pressing any switch (apart from SEL)
should make the corresponding LED flash out of time with the other LEDs on the front
panel.
Pressing a SEL switch should light the corresponding LED.
Pressing any of the switches on the TR computer section should flash the corresponding LED. Pressing the
D-Pot should turn off the flashing ‘Empty’ LED and flash the ‘Wr rot’ LED.
Test ots (tp)
This mode scans all the modules from the top left to the bottom right of the unit and
displays the value of the last rotary control not turned fully counter clockwise. If all
controls are turned counter clockwise then the display shows ‘tp’.
To use this diagnostic first turn all controls fully counter clockwise. The module SEL LEDs will flash on
all modules with a control not in the correct position and the individual pot LEDs will light green on all
controls not in the correct position. Turning any control should make the display change from ’02’ to ‘255’.
Note that ‘02’ is the lowest value that can be read before the pot is skipped.
The decimal points on the two displays are used to show numbers greater than ‘99’. The left hand decimal
point lights to indicate that you should add a 100 to the displayed value and both decimal points light to
show that you should add 200 to the displayed value, hence:
4.4.9 Set DIM Level (d1)
Select DIM Level by turning the D-Pot till the display shows ‘d1’.
Press the D-Pot to show the current DIM level. The level can be varied from –3dB (‘03’) to –30dB (‘30’).
Press the D-Pot once more to change the DIM level.
‘101’ will display like this: whilst ‘201’ will display like this:

4.5 Software Download and Installation
Software to upgrade your X-Rack unit should be downloaded from the SSL website
(www.solidstatelogic.com/support).
The X-Rack software is packaged as a 50kB (approximately) java archive, the format of which is
compatible with both PC and Macintosh (PowerPC and Intel but OS X only) platforms. Some users may need
to install additional files on their computer before continuing – see System Requirements below.
4.5.1 System Requirements
PC users should ensure that they have the latest version of Java installed. This can be downloaded from
www.java.com. There is a link to this address on the download page.
To enable Java to access external MIDI devices, Mac OS X users may need to download and install either
‘Plumstone’ (PowerPC) or ‘MandolaneMIDI’ (Intel) from www.mandolane.co.uk. Drag this file into the
‘ /Library/Java/Extensions ’ folder then restart the Macintosh before running the upgrade utility.
4.5.2 Software Update
Once the software package has been downloaded, it will need to be moved onto a Mac or PC that is
connected to the X-Rack via MIDI after which you will be ready to install the new software. The following
steps detail this process:
1. Ensure that the X-Rack is turned on and connected to a MIDI port on your PC/Mac.
2. Enter Setup mode and turn the D-Pot until the display shows
‘fl’ (‘Flash’). Press the D-Pot and the display should change to
read ‘te’ (‘Test’).
To exit from this mode without updating software turn the unit off and on.
3. Close all current applications on your PC/Mac.
4. If upgrading from V1.0/0 or V1.1/0 double click on the
xrack_flash.jar file. If upgrading from V1.2/0 or
later, double click on the xrack_vn_n_n.jar file (where ‘ n_n_n ’ denotes the new version number). You
should see the SSL X-Rack Software Update Utility window appear:
5. o to the In MIDI Port menu. Select the MIDI IN port which is connected to your X-Rack from the drop
down list. In the example shown below this was ‘port 1’ on an 8-Port interface. If nothing appears in the
list check that you have installed the files listed in the System Requirements section opposite.
