INTRODUCTION  
Expand your studio with an SSL!  
Solid State Logic are delighted to introduce its latest analogue offering, the X-Panda,  
built with the very same SuperAnalogue™ DNA as our AWS, Duality and Matrix  
consoles. SSL sincerely hope that you enjoy this compact analogue product.  
X-Panda is a 24 Input mixer that can be used for tracking and master mix summing.  
The purpose of the X-Panda is to augment any existing system. Obviously a natural  
partner would be SSL’s own award winning X-Desk. However, X-Panda is designed  
to work with any analogue audio equipment, the limit is really your own imagination.  
Remember this is a true expander in the convenient analogue domain.  
X-Panda was primarily born out of requirements from existing X-Desk owners for  
additional inputs for a larger analogue studio system. When used in conjunction with  
an X-Desk it creates a 44 input SSL studio mixing system.  
Initially the X-Panda may appear to be a relatively basic analogue console, however  
there are a number of design innovations that could significantly enhance your  
studio’s sonic output. If you take a short time to read this guide through, hopefully  
you will discover a few novelties, which may enhance your recording and mixing  
sessions.  
You may wish to consider exactly how you will integrate X-Panda into your studio  
along with your existing equipment. Taking time to plan X-Panda’s integration can  
yield sonic benefits later on.  
Some example system setups are included in the X-Panda Installation guide included  
in your package.  
X-Panda can be used as an elegant and ergonomically refined desktop mixer or placed  
in a 19” rack (by virtue of the supplied removable rack ears) in a 7U space.  
Like all SSL SuperAnalogue™ products, it is extremely robust, hand-built in the UK  
with an all-metal chassis and utilises high quality controls and components.  
X-Panda combines a 24 input SSL SuperAnalogue™ mixer with the ability to truly  
“expand” the other equipment in your studio.  
 
The X-Panda Mono Channel Strip  
Inputs – Channel Input (CH IP), Alternate Input (ALT)  
Each one of the 8 mono channel inputs (CH IP) on the X-  
Panda has a choice of two Line Inputs. The first input is  
traditionally sourced from the Output of a microphone pre  
amplifier, D.I box or perhaps even a line level instrument.  
These connections are labelled “LINE IN 9-16 (1-8)” on the  
rear of the desk. They are so labelled due to the fact that you  
may be using X-Panda stand alone or in conjunction with an X-  
Desk or indeed additional audio equipment.  
The second Line input is selected via the switch labelled “ALT” and is most  
commonly used for Monitor return playback signals, perhaps from a Digital Audio  
Workstation (DAW). These connections are labelled “ALT IN 9-16 (1-8)” on the rear  
of the desk.  
Once you have selected your Input, it then has a +/- 20 dB gain Level Trim, indented  
in the centre at Unity Gain and a Phase Reverse “Ø” button.  
The Post gain signal can also then be affected by Insert processing (perhaps an EQ or  
Dynamics processor.) by pressing the “INS” switch. It is worth noting that in SSL  
tradition the Insert Send is always active, which can be creatively utilised if you so  
wish. Engaging the “INS” switch will activate the Insert return. (All Mono Channel  
Inserts are connected via the “INSERT SEND/RETURN 9-16 (1-8)” connections on  
the rear of the desk)  
The Tri-colour Led under the level control is a 3 colour indictor of signal presence  
and level. By default the following audio levels are indicted by the following LED  
states:  
Green =  
Yellow =  
-24 dBu  
+4 dBu  
+21 dBu  
Red  
=
Remember it is possible to rescale the X-Panda’s metering to a +18dBu (as opposed  
to the standard +24 dBu) scale via the rear panel DIP switch. This would then  
provide the following channel meter scale.  
Green =  
Yellow =  
-24 dBu  
0 dBu  
+16 dBu  
Red  
=
Note: The Red LED will light before actual audio clipping, which can serve as a  
useful warning when recording.

Outputs - Direct Channel Outs (CH OP), Post Fader  
Each Mono channel of the X-Panda has a Direct Output. The  
Channel Direct Outputs (CH OP) are primarily used to feed the  
inputs of your chosen recorder or DAW. On the rear panel connection panel of X-  
Panda they are labelled “CHAN OUT 9-16 (1-8)”.  
The operator has a choice of whether the output Signal is sourced Pre or Post fader.  
By default the output is Pre fader / Post Input Trim but by selecting “POST” the  
Output level will be sourced after, and thus controlled by, the Channel Fader. This is  
useful if in classic British audio engineering style one wishes to “ride” the signal level  
to tape or in this modern day and age, the DAW.  
Stereo Cue – Post Fader, ALT source  
This is the channel send to the Stereo CUE Bus. There are  
separate controls for both Level and Pan, and this is normally  
used as a Cue audio feed for the recording artist. But this is just  
the beginning!  
Selecting the POST switch will source the Stereo Cue post the  
channel fader.  
A very useful feature of the X-Panda mono channels is that the CUE ST can source  
the ALT channel input (even if it has not been selected as the main channel input.) To  
achieve this simply engage the “ALT” switch. This is useful when recording as an  
entirely independent Cue mix can be built up.  
Alternatively if the requirement is for a large analogue summing system (when used  
in conjunction with an X-Desk), an additional 8 channels could be connected to the  
ALT input, sourced on the CUE with independent Level and Pan, and reassigned to  
the MIX bus via the CUE to MIX button on the Master section of an X-Desk.  
Note: Selecting ALT (on the CUE send) when it is sourced as the Channel Input will  
result in no change to the Cue source.  
FX Sends 1&2 and Stereo Returns (ST RET)  
Each Mono Channel on the X-Panda has two mono FX sends  
(FX1 and FX2)  
The Send is permanently ON but rotating it fully counter  
clockwise will result in no signal being sent onto the FX bus.  
Normally the FX sends are sourced Post Fader but they can be globally switched for  
the whole X-Panda by the PRE switches on the last Stereo Channel. (See next  
section)

Channel Pan, Fader Cut & Solo  
At the base of the X-Panda Mono channel strip you will find  
traditional analogue desk functions.  
The channel stereo “PAN” control, which controls the channels  
Left/Right positioning on the Stereo Mix bus.  
The analogue signal level FADER, for feeding the Stereo Mix Bus  
or controlling the CH OP (Direct Channel Output) level.  
Above the Fader you will find two switches:  
The “SOLO” button, which mutes all other channels and provides  
an AFL monitoring signal, and finally the “CUT” button which  
immediately mutes the channel’s output.

THE X-PANDA STEREO CHANNEL STRIP  
The X-Panda features 4 Stereo Input Channels that differ slightly from the Mono  
Channels.  
Stereo Inputs – Channel Input (CH IP)  
The X-Panda Stereo Input channels (CH IP) feature a +/- 20 dB gain stereo Level  
Trim, indented in the centre at Unity Gain and a pair of independent Phase Reverse  
Ø” switch for both the L+R Inputs.  
The Post input gain signal can also then be affected by Insert processing (perhaps  
stereo EQ or Dynamics processing) by pressing the “INS” switch. On the Stereo  
channels on the X-Panda the Insert point is true Stereo.  
It is worth noting that in SSL tradition the Insert Send is always active, which can  
creatively utilised if you so wish. Engaging the “INS” switch will activate the Insert  
return. (All Stereo Channel Inserts are connected via the INSERT SEND/RETURN  
ST 1-4 connections on the rear of the X-Panda)  
There are independent Level Meters for both Left and Right Signals of your Stereo  
source.  
The Tri-colour LEDs under the level control are 3 colour indictors of signal presence  
and level. By default the following audio levels are indicted by the following LED  
states:  
Green =  
Yellow =  
-24 dBu  
+4 dBu  
+21 dBu  
Red  
=
Remember it is possible to rescale the X-Panda’s metering to a +18dBu (as opposed  
to the standard +24 dBu) scale via the rear panel DIP switch. This would then provide  
the following channel meter scale.  
Green =  
Yellow =  
-24 dBu  
0 dBu  
+16 dBu  
Red  
=
Note: The Red LED will light before actual audio clipping, which can serve as a  
useful warning when recording.

Stereo Outputs - Direct Channel Outs (CH OP), Post Fader  
Each X-Panda Stereo channel features a dedicated Channel Output (CH OP). This  
provides a direct Stereo Output.  
Normally this is sourced Pre Fader but by engaging the “POST” switch that source  
becomes Post Fader. The Channel Direct Outputs (CH OP) are primarily used to feed  
the inputs of your chosen recorder or DAW. On the rear panel connection panel of X-  
Panda they are labelled “CHAN OUT ST 1-4”.  
(Note that there is no “ALT” option on the X-Panda Stereo Channels)  
Stereo Cue Send  
Provides a Stereo Send primarily for Cue purposes. By default the signal is sourced  
pre fader but additionally it can be sourced after the Channel Fader by selecting  
POST”. It may be worth bearing in mind that if you are using X-Panda in  
conjunction with an X-Desk and on the X-Desk are using the “Cue to MIX” function  
you may wish to turn this CUE ST send off on the X-Panda Stereo channels.  
FX Sends 1&2  
There are two FX sends on the Stereo channels and they take a summed Mono signal  
of your Stereo Input source. By default the signal is sourced post Fader.  
6
 
Note that it is possible to globally switch the FX Sends independently for the X-Panda  
to source the signal pre fader by engaging the “PRE” switch for either of the two FX  
Send busses on the last X-Panda Stereo Channel.  
Channel Balance, Fader, Cut & Solo  
At the end of the Stereo Channel there is a Balance control. Note  
that this is entirely different to the Pan control on the Mono  
channels. Simply, it controls the channels respective Left/Right  
Level feed to the Stereo Mix Bus. If you are unfamiliar with this  
type of control it may be worth playing some stereo material into  
the channel and experimenting with the control to perhaps give you  
an idea of it creative potential.  
In addition to the usual Solo and Cut switches along with a long  
throw Channel fader, all of which function as they do on the Mono  
channels.

ADDITIONAL INFORMATION  
Rear DIP Switch Options  
The rear of the X-Panda unit features a 4-way DIP switch which allows you to change  
the Meter scaling of the signal LEDs on the channels.  
Switch number “1” alters the meter scaling between:  
0 dbfs= +18 dBu  
or 0 dbfs= +24 dbu  
Note: that the default factory setting is set to +24 dBu  
The Diagnostics 1,2, and 3 switches are for internal SSL factory use only and should  
not be engaged by the user without dire repercussions on a truly monumental scale.  
Well perhaps not that bad, but please don’t do it!  
Cascading X-Panda and X-Desk  
One of the most useful features of the X-Panda/Desk is the ability for multiple units to  
be cascaded together to build a bigger SSL system.  
It is possible to connect an X-Panda and X-Desk units together by simply connecting  
the rear panel connection on the X-Panda “UNITE” to the “X-DESK LINK IN” on  
the X-Desk. You should connect your monitor loudspeakers and FX processors to the  
X-Desk as it will be the main audio MIX bus, as well as acting as the master sends for  
the CUE and FX busses.  
Currently we recommend that you connect no more than 8 X-Desk/Panda  
combinations in a cascaded array.  
As mentioned, once connected the MIX, CUE, FX 1&2 and AFL solo Busses are  
combined on the master X-Desk.  
So for example:  
If you engage SOLO on any channel, all other Channels in your cascaded X-  
Panda/Desk System will mute.  
A single FX processing unit can be connected to the FX 1 or 2 output of the Master  
Desk yet can be fed audio from sends on any of the cascaded desks.  
More advanced users may wish to consider the possibilities of such delights as  
parallel compression, differing FX destinations, extremely complex Cue sends and a  
whole host of other creative possibilities

Using X-Panda with an X-Rack Summing System  
Although not essential, a natural partner for the X-Panda is an SSL X-Rack. While  
some of the more obvious X-Rack modules such as the Mic Amp (XR621) or the  
VHD Input modules (XR627) would be suitable for recording various sources, and of  
course the X-Rack EQ and Dynamics modules, Superanalogue (XR625) & (XR618)  
or 4000 series (XR425) & (XR418) would be a natural partner for audio processing  
duties.  
However the real fun begins if you would like to create a “bigger” analogue mixer.  
Because the X-Rack has a “Mix Bus Link”, if you have a Master Bus Module  
(XR622) simply connect the X-Panda’s “XRACK EXPANSION” to the X-Racks’  
“Mix Bus Link”  
Note: The X-Rack REC BUS (Record Bus) is fed from the X-Panda’s ST CUE as it  
has no associated bus.  
Using X-Panda with other audio equipment  
While you may assume that X-Panda is designed to only work in conjunction with  
other SSL equipment, you would be mistaken. X-Panda can be a welcome addition to  
any existing set up.  
Use with another audio mixing console:  
Lets assume you have a classic console from the good old days, or a highly affordable  
offering from a current manufacturer. X-Panda allows you to add additional inputs for  
this device. Simply connect from the Unite socket on the rear of the X-Panda to your  
audio console. Remember that you can “break out” the 8-way D-sub (Using a  
commonly available D-Sub to 8x XLR cable for example) into its component audio  
signal elements. So you can access the Stereo MIX bus, Cue bus the two Mono FX  
Sends and of course, the AFL bus. You do not have to use all of these of course. SSL  
are providing you with a set of tools, and as ever you choose the correct one for the  
job. A simple setup would involve simply connecting the X-Panda MIX bus to a  
Stereo Input or indeed two mono channels. This would provide many more inputs into  
your console. A more complex set up might involve the above in combination with  
the CUE and FX also connected. Useful if you wish to access hardware outboard FX  
equipment that is connected to the other mixing console. How you accomplish this on  
your other console will either involve donating a channel for this purpose or some  
have dedicated summing input often called Bus injects. Consult the documentation  
that came with your other audio mixer to see what is possible and how it might work  
best for you in your studio. No two mixers are alike!  
Use with another analogue summing system:  
The last few years has seen a growing appreciation for the benefits of analogue mix  
summing. There are quite a few systems available and X-Panda can work in  
conjunction with any of them.

Racking your X-Panda  
Supplied with the X-Panda are 2x Racking “ears”. These can be simply fitted to the  
Desk by the use of 3x screws per side (included) thus facilitating 19” rack mounting  
of the X-Panda. We recommend 4x screws for securing an ear equipped X-Panda into  
a standard 19” rack.
