Several years have passed since InnovaSON
introduced the first digital system designed to
meet the needs of LIVE SOUND production:
artists on-stage, impatient producers (tight
budgets), live sound quality identical to studio
recordings, complex productions, etc.
LIVE, for InnovaSON, is a “keyword” reflected in
the products; products that are reliable, sturdy,
and capable of working without a problem, show after
show. Thought was not only given to limit size and
excess weight (as freight in a lorry, car or plane), but also
to speed up the installation, and especially
of the sound engineer”, an essential condition in the creation of
quality live performances.
to “free the spirit
INTRODUCTION 1-1
Thanks to the success of the MUXIPAIRE system, InnovaSON was in touch with numerous users,
who all wished for a digital mixing desk that would, at last, satisfy all their requirements for live shows
in the 21st century:
Total memory of the functions necessary for complete audio signal processing
Immediate reminder of the state of the whole console
Simple to use in spite of sophisticated automation
Sound quality without compromise
All the advantages of a completely computerised digital system
These are the essentials that InnovaSON settled on throughout the design of its range of digital
consoles.
Designed from standard elements in InnovaSON’s modular (or custom) digital audio systems,
InnovaSON consoles now benefit from the field experience gained from those previous products.
All the team at InnovaSON sincerely thank all those who brought another small stone to the structure,
by their suggestions, particular requirements, or sensible comments. Although completely digital,
InnovaSON consoles will not upset a user brought up on classic analogue systems; on the contrary,
their original three-part concept (mixing desk, local and distant audio system racks), brings more
flexibility and quality, without compromise.
Our greatest satisfaction will be to learn that each user has found, in Live Sound, a work tool perfectly
adapted to their needs.
Sensoft 8.1 brings something new to the world of Live Sound – you define the number and position of
all the functions necessary for your mix.
Naturally this number is determined, on one hand, by the number of faders on your control surface
and, on the other hand, by the available DSP resources in your system.
The figure below gives the maximum number of resources that Sensoft 8.1 can handle on various
InnovaSON consoles.
Console faders can handle inputs coming from distant and local audio racks, as well as controlling the
busses necessary for the different mixes required for these inputs.
Each of the console faders can handle the following functions:
The number of faders available in this grid corresponds to that available on the console (shown here is
the Sy80). The Grid functions in the same way for any console as long as it supports Sensoft 8.1.
Later on in this manual we will show you how to access and use the configuration grid.
To give you the time to fully understand and master this feature, preset configurations
allow you to quickly set the parameters of your console. Having first inserted the floppy
disk “Examples”, use the Import function to load these standard configurations.
1.D Spread zones
Let’s take a few moments to consider the concept used by InnovaSON to exploit more physical inputs
and mix busses than there are faders on the console, without having to resort to a system of layers.
As you saw previously, InnovaSON designs consoles dedicated to, among other situations, live
applications. It was therefore important to establish a design that took note of the following points:
A console with a size and weight lower than its analogue counterpart
Retention of the user-friendliness inherent in software previous to Sensoft 8.1
To always have a global view of the general state of the console on the monitor screen
To have to hand the maximum number of controls, for fast and effective user reaction
This last point made InnovaSON decide to implement the X
8.1.
Whether for the management of inputs or the management of busses, the general principle is the
same: a full channel can control a single physical I/O or of a set of physical I/O. In the latter case, the
channel can be compared to a “fader bank”, because every time it is selected, it spreads out all the
channels it controls, in a zone defined by the user.
The channels associated with
one, or a group of, physical inputs
In the same way, Aux, Group or Master channels can spread thei
L, R, C and M busses if necessary, in this case you can compare
them to “Bus Banks”
The spread zone as defined by the user, made
up from as many X
FAD as neccessar
The figure above shows an example of 8 “banks”, each spreading 16 XFAD inputs. A swift calculation
shows that, in theory, you could control 8 x 16 = 128 inputs with only 8 + 16 = 24 faders…….what a
dream!
One of the major points of Sensoft 8.1 is that the number of “banks", and their arrangement as well as
the number of channels spread by the "banks", is defined by the user. Each user can effectively "draw"
the console according to their own needs.
The Sy48 console is a single block, 'all in one' system, with the
local Mix Box and the control surface within the same frame.
The Mix Box provides 6 slots for housing modules of 8 inputs or
8 outputs (analog, digital AES or Ethersound). Its modular
structure lets you configure the inputs and outputs according to
your needs. Hence, when used by itself, it can be equipped as
shown below, with 32 mic/line inputs, 16 line inputs, 16 analog
outputs with processing, and 16 line outputs.
The platform features everything you expect from a digital mixing console in a particularly compact
frame weighing less than 40 kg, including :
48 motorized and assignable faders with immediate access to the main parameters (selection,
monitoring and mute)
48 LED bar-graphs for immediate metering of input or output signals
A section for adjusting all the parameters of the current selected channel
A section for managing memories
A collapsible 12" screen for real time visualization of all the mix parameters
An access panel to all the main functions (patches, monitoring, talkback circuit, …)
A PC computer handles everything in the system
A keyboard/track-ball drawer for labeling and access to advanced functions
Space reserved for the local audio rack, where the I/O modules, the MC-64 controller and the DSP
Sy48 module can be found.
The digital aspect of the console is managed by the MC-Optical controller module, which generates
the audio clocks, drives the bus, and handles communications with the console’s integrated PC. This
module is equipped with BNC and optical connectors dedicated for the connection of a Stage Box,
which then allows the remote management of 48 Mic/line inputs and up to 32 mix busses. Therefore,
the slots of the local Mix Box can be equipped with more output modules, which leads to a maximum
of 6 analog or AES output modules, plus the 16 line outputs available on the SubD25 connector… that
gives us a total of 64 local outputs.
Coaxial or optical cable transmission is not an option. Every InnovaSON platform is equipped with this
transmission system. No need to invest in any format converter or other hardware to establish a
connection between a Stage-Box and the Mix-Box. Just connect the MCoptical (card featured in the
local rack) to the SCoptical (card featured in the remote rack) to immediately benefit from a digital
transmission, where 64 channels can be exchanged between both audio racks..
In the local audio rack, on top of the MC
controller, one
OPTICAL
can find the DSP (digital signal processor) Sy48 module, which
handles the digital processing of signals, and all the algorithms
that the console functions may use. This module is equipped
with 4 Sub-D 25 connectors which can manage 16 inputs and 16
outputs of line level signals,
which therefore add up to the resources
provided by the I/O cards of the rack. Four Sub-D /
XLR adapter cables are provided with the console.
The firmware currently available in the DSP Sy48 card provides simultaneous mixing of 64 inputs (48
Muxi + 16 line inputs) to 34 mix busses (two of which are reserved for stereo monitoring). The mix
busses have no predefined functionality. It’s up to you to use them as groups, sub-groups, auxiliaries,
masters, matrixes, …
The inputs/outputs accessible via the SubD connectors can be used as line inputs o
mix bus outputs, bus also as Insert Send/Return pairs to insert external processors.
As with any InnovaSON console, once the input and output cables are connected to their designated
devices, you no longer need to touch them. All patching operations are done electronically and are
memorized – all of which is managed directly from the control surface.
The Control Surface is relatively easy to understand; even beginners will rapidly feel at ease with the
digital mixing provided by the Sy48.
The various console channels are equipped with motorized faders which move into position rapidly,
quietly, and even feature a “sensory point” that can be felt under your fingers. Therefore, you always
have the last memorized position in mind.
The bar-graphs located just above the faders provide direct metering of various working levels, after
processing (dynamics, EQ) or before processing (reflecting the output level of the pre-amps),
depending on the option selected in the general preferences.
Last but not least, as soon as the console is switched on, the flat
LCD screen displays the main mix window or, depending on
preference settings, the other control windows of the platform. The
internal computer drives the DSP in real time according to the
actions taken by the user on the control surface. If necessary, the
console’s internal PC can be removed and replaced by the external
PC connection kit. You can therefore control the platform from any
PC on which Sensoft has been previously installed.
To make things easier in a given situation, provision has been made to replace the internal flat screen
by another SVGA standard screen. The keyboard and mouse can also be relocated (or replaced) by
removing them from their drawer.
2.B Personalization, options
Each system, within certain limits, can be adapted to the latest performances and options of the
InnovaSON range of products.
For this, please contact our authorized technical services for specific updates: DSP resources,
Sensoft, advice, etc
2.B.1 L.E.M : optional External Mix Box
In certain situations, it could be more practical to access the audio cards without having to go around
to the back of the console. In these cases, The L.E.M. option (for Local External Mixbox) is the
solution. You also benefit from 8 slots instead of the 6 inside the console.
The L.E.M. is equivalent to the Sy48's internal audio rack, except it is located outside of the
console. All the modules that would normally be fitted in the console's internal rack are 100%
compatible with the L.E.M.; no updating of the card is necessary to use the L.E.M.
The L.E.M. is the same local audio rack as the one used by the Sy80 platform. Therefore, you must
follow the same rules concerning the location of the audio cards within the rack:
Always start by the output cards (XO, MO, DO) and then finish by the input cards (SI, DI), if you
are using any.
The Stage-Box (is you are using one) will follow the inverse rule: first the input cards, then the
output cards. Don't forget that the cards with the Hyperdrive option (XO-8D2, DO-8X, DO-8Xes)
do not work in a Stage-Box. Only the MO and DO-8A are designed to work in a Stage-Box.
A standard SG3100 audio rack is equipped with two internal power supplies, with automatic
switchover if a problem was to occur on one of them. For the automatic switchover to function
properly, it is imperative that both power supplies of the rack be connected to the mains.
The PSU module, in the last

Blank face plates are used on the integrated audio rack on the back of the console. They are placed in
the audio and MC cards position. One of these cards, the DSP Sy48, is replaced by the SF2077
module, which is a Jeager adapter enabling the connection to the external Mix-Box.

A Quadfad module features 4 motorized faders. Each fader has its own 4-character label. The 12
Quadfad modules of the console are identical. Sensoft lets you determine the purpose of each fader.
Their presence is automatically detected by Sensoft.
The main characteristics of a Quadfad module are as follows :
ALPS 100 mm motorized fader
8 bit linear conversion for servo-control and fader positioning
nominal positioning time: 100 ms
Sensory memory of stored fader position
Illuminated switch to indicate Channel selection
Illuminated [CUE] switch (green) to indicate assignment to the Monitor bus
Illuminated [MUTE] switch (red)
4-character Labeling display (adjustable highlighting / for when the channel
is selected)
2.C.3 The CHANNEL CONTROL panel
Integrated within the console frame, and
ideally positioned to be accessed rapidly, this
panel centralizes all the channel's parameter
controllers (gain, EQ, Dynamics section,
etc…). Pan control, and amongst other things,
access buttons to the various 'LIVE' functions
such as Copy, OverRam, and the patch
windows, are also found on that panel.
2.C.4 Screen and UTILITIES panel
Three sections complete the access to the
console's functions with, from left to right, the
page and show management panel, the
central screen to visualize the current mix, and
the patch grid, monitoring circuit management
and talk-back mic panel.
On top of the screen, you will find three small holes that let you adjust
brightness and other settings. A user manual for the screen is supplied
with the console to guide you in the procedure. In any event, one of the
configuration menus offers an automatic adjustment, which will
optimize settings according to the video signal' characteristics.
During the console's startup procedure, the image may be unstable. This is perfectly normal. As soon
as Sensoft is launched, the image will be stable.
2.C.5 On the front of the console
Left of the keyboard drawer, you will
find 3 connectors:
- A 1/4" headphone jack
- An XLR connector for a talk-back mic
- A USB connector for any storage
device
Volume of the headphone jack can be adjusted with the [Level] pot of the monitor section
Read this section carefully in order to use the control surface safely.
1.Never connect a receiver (camera) that has its own phantom power activated: this
would destroy the output to which it has been connected. Switch the phantom power
off, or if this is not possible, go through an external device first (isolation transformer,
intermediate pre-amp, etc…).
2. Only the swapping of presumably defective modules is advised, and made possible by
the modular philosophy of the control surface.
ANY SWAPPING OF MODULES MUST BE DONE WITH THE CONSOLE SWITCHED
OFF.
3. Do not store or use the console in extreme temperature conditions, or in an
environment where it might be exposed to vibrations, dust or humidity.
4. Never use any liquid to clean the surface of the console (ideally, use a soft and dry
cloth). Only use water or ethylic alcohol to clean the casing and silk-screen printed
surfaces; other solvents could damage the paint or plastic parts.
5. Do not place the audio racks, local or remote, or the console itself, too close to strong
electromagnetic radiation sources (video monitors, high-voltage cables, …), as this
might cause a degradation of audio quality via induced currents in the connections
and frame.
Before you move the console, make sure that
everything is disconnected. Never put excessive
pressure on the pots, switches and connectors.
The Sy48 console provides two grips under the
plastic flanks on each side, for easy maneuvering.
2.F Power supplies and EC standards
The Sy48 console may be powered by any voltage ranging from 90 et 253 Volts AC / at 47-63 Hz.
The power supply must be earthed.
For optimal performance, it is essential that the earthing network be free of noise, since all signals are
going to be referenced to it. A central point must therefore be determined as the main earthing
connection, and all other earthing connections must originate from that point. It is recommended that
you pull an extra earthing wire from each socket, wire that will be directly connected to the central
earthing point: this is the best way to ground all the devices of your installation.
When the console is in use, do not block the cooling vents. Be especially careful of that if you are
using the console while it remains in the lower half of its flight-case.
For electrical precautionary measures, please refer to chapter 10 - Appendices
2.G Connections
Connections to the control surface are reduced to a minimum for easy installation, and an increased
reliability of the system. To use an external PC (desktop or laptop) you will need accessory SG9008
which will replace the internal PC, with connectors provided for hooking-up the external PC.
2.G.1 Audio connections
The Sy48’s platform connections are all standard and were chosen to correspond with the most
widespread in the professional live audio industry. No need to buy extra adapters or specific
connectors when using the console in a normal environment. If, however, you have specific needs,
feel free to contact InnovaSON’s technical service. The contact information can be found on our web
site and at the end of this manual.
Do not connect other audio devices which are switched on, before you power up the console. The
Sy48 is a computerized platform which starts up in the last saved statuses, that you do not necessarily
know. Unknown parameters relative to gain settings, or output levels, could damage various audio
equipment (power amps, speakers,…), or even cause hearing damage to people too close to the
speakers. Good practice would be to always shut down the console on a blank page, in which all the
settings would be zeroed.
The standard screen housed in the console is a collapsible color LCD flat screen. The collapsed
position is used during transportation. The screen can be tilted to suit your viewing position. A user
manual for the screen is supplied with the console.
With a stylus, the holes on top of the screen's plastic casing give you access to the brightness, color
and contrast settings.
Instead of the integrated screen, you can use any other standard SVGA monitor. Pay particular
attention to the electromagnetic radiations that could appear when using a CRT (Cathode Ray tube)
monitor.
The screen’s connector is linked to the internal computer, on
the rear of the console. If you are using an external
computer, the screen (built-in LCD or other) can be quickly
connected to the current working computer.
2.G.3 Connecting MIDI equipment
The Sy48's MIDI connectors are located on the internal PC,
at the rear of the console: they will accept any MIDI compatible device. To make sure your
connection will work, always use a cable that complies with MIDI specifications. Sensoft
provides a utility tool for testing MIDI cables: refer to section 8.
2.G.4 Connection of an external power supply
An external power supply unit SV0038 can be connected to the console to provide backup to the
internal power supply in case it fails. It is even possible to connect two external power supplies, and
control the power-up of the console remotely from them.
Contact our technical services for further information on that matter.
The Jaeger connecter dedicated to connecting an external power supply is equipped with a protection
cap that MUST be in position when this function is not used. The cap keeps any short circuits from
occurring between the Jaeger connector's pins.
2.G.5 Connecting an external PC
Any IBM-PC compatible computer, hosting a processor of at least 800MHz with 64Mb of
RAM can be used to supervise the operation of the console instead of the internal unit. The
SG9008 accessory is necessary for this type of operation. While on tour, we more than
recommend that you purchase this accessory and keep a laptop PC ready, to "save the day".
The Windows XPE operating system installed in the console’s internal PC is an XP core
assembled by InnovaSON developers, in order to contain only the required elements
necessary for managing the Sy48 platform. This is a mandatory condition to guarantee a
stable, crash free, system. InnovaSON can not be liable for the instability of the operating
system installed on your personal computer, connected to the platform. Our technical support
is always ready to help you configure your computer for such a use.
2.G.6 Connecting an optional Stage-Box
The MC
OPTICAL
and SC
cards, supplied as standard with the Mix-Box and Stage-Box, have their
OPTICAL
own coaxial and optical transmission system. It is very easy to initiate this transmission, as shown in
the diagram below. The link may be uni or bi-directional. If it is uni-directional, only one TX of the
Stage-Box will be linked to the RX of the MC. In this case, the console is in « Slave » status and
cannot control the gain and PH48V of remote microphone input cards.
We must insist on the need to use good quality cables or fibers and to take particularly good care of
the connections used for this link.

Nothing is easier than adapting the console to your needs, whether you are using it for monitoring,
Front of House, theatre, opera, broadcast…
The only limitations are:
No similar type cards (input/output) on the same remote and local slots (A, B, C,…).
Maximum simultaneous mixing of 48 Muxi inputs (inputs coming from SI and DI cards) plus the 16
line inputs of the DSP card (Sub-D). These 48 Muxi inputs can be selected, for each page of the show,
amongst the 64 possible inputs.
Maximum transmission of 32 busses to the Stage-Box, patchable on 4 MO-8D3 or DO-8A cards.
These cards must imperatively be installed in slots E, F, G or H of the Stage-Box.
Using remote output cards condemns the use of input cards installed on the same local slots.
Please refer to the Sensoft 9.1 Addendum for further detail.
Example of a Stage Box and its optical fiber
Also refer to section 9 for the rules concerning the use of the Stage-Box.
2.G.7 Digital audio clock sync with external devices
There are several ways to sync the digital audio clocks of external devices with InnovaSON’s platform
clock. This can be done through SRC (Sample Rate Converter), on one or several digital audio inputs
or via a Word-Clock or AES link, to synchronize the entire system to the same clock source.
Principle of the SRC (real-time sample rate conversion) :
This allows each equipment to keep its internal digital audio clock source. The digital inputs (AES or
other) is immediately followed by a SRC algorithm allowing the synchronization of the incoming
sample rate to the one used by the receiving system. The conversion has a range of about 10%
around the sample rate of the receiving system. The DI-8SRC
an algorithm. Each one of the card’s 4 AES inputs can receive an external digital audio signal with a
sampling frequency between 32 and 50 KHz. The card output is itself synchronized to the global clock
rate defined in the InnovaSON platform.
This feature has the advantage of letting you connect several digital audio sources to the console
without having to worry about syncing the sources to one another. Be careful: the SRC creates an
additional calculation latency, which leads to a non-negligible delay of up to 1.5ms in the « worst case
» conversion… Moreover, again for calculation reasons, the original 24 bit resolution at the SRC’s
input will be « reduced » to 20 bits after conversion… Rest assured: the audio quality is still very
InnovaSON card is equipped with such
good.
Using Word-Clock input and output :
When the console is meant to exchange a great number of digital input/outputs or is
integrated in a digital audio environment where all the machines are synced to one
another, it might be more useful to use the Word-Clok I/O of the platform. The console
can be used as the « master clock source » or be synchronized to a reference clock. In
the first case, just take the WC output of the MC and/or SC (if there’s a Stage-Box) and
distribute that signal to the WC inputs of the other devices. Note that the WC signal is
available both on the local audio rack and on the optional Stage-Box. If, on the other
hand, you wish to sync the console to a reference clock (48KHz), connect that clock
signal to the MC’s WC input. If you are also using a Stage-Box, then you MUST use
the WC input of that Stage-Box’s SC instead. The Stage-Box being the clock master for
the platform, it must be the one receiving the external clock signal. If you are using a
Stage-Box, the MC’s WC input is ignored (the L.E.D normally showing synchronization stays off).
Using the AES input:
The MC and SC cards also feature an AES input. When a digital audio signal is connected to this
input, the platform can extract the clocking information from the signal and sync to it. The same rule
concerning the Stage-Box applies here : always sync the Stage-Box if you are using one, not the MixBox.
A few cases where no external synchronization is necessary :
There are a few cases where it is not necessary to use any sync signal between the console and
digital audio devices. Indeed, when the console feeds a digital audio signal to a device for processing
purposes (effect, dynamic processor, digital recorder, …) which is then returned to the console after
processing, no need to use an SRC or a WC. Just configure the external device so it syncs on the
incoming AES signal (fed by the console). The signal supplied by the device’s output will also be
synced by the incoming signal, and therefore, to the console’s digital audio clock.
For signal exchange with digital outboard, it is therefore possible and even simpler to use DO-8 and
DI-8A cards without worrying about syncing devices with one another. This will be done by configuring
each outboard’s digital clock source.
2.G.8 Connecting headphones
There are no restrictions to the use of headphones on the console’s
headphone connector (refer to section 2.C.5
not to use the MC card’s headphone jack, which goes way back in
InnovaSON’s history of developments! This output was originally designed for
monitoring functions of the Muxipaire, when no console was used. This output
does not feature a volume control.
). However, it is strongly advised
CAUTION:
operational only when using a Muxipair and when the card is configured as an MC and not as
an SC.
