1.1 Integrated Monitoring Solution
1.1.1 Modular Architecture
Trinnov processors are based on a modular hardware and software architecture.
Modular hardware architecture:
Trinnov audio processors use the same audio core associated with different combinations of I/O
expansion boards. Multichannel processors can be custom-configured depending on the type and
number of necessary I/Os whereas Stereo processors hardware is fixed. Please see the Hardware
Guide chapter for more details on the hardware of your model.
Modular software architecture:
oSystem software: all Trinnov processors run the same system software. It includes all the
main features of a standard loudspeaker processor as well as a complete DRC/Submix
engine to emulate end-user listening conditions. However, most of the time the system
software is used with one or more optional software modules:
oOptimizer Runtime: runs and applies the Optimizer filters as a "black box":
Measurement and analysis functionalities are not available.
The calibration and computation must be performed on another machine where the
Optimizer Toolbox is installed.
oOptimizer Toolbox: implements loudspeakers calibration and analysis tools:
Optimizer Settings, Target Curves, Multipoint Calibration & Graphs.
Measures and computes the Optimizer filters which then are loaded in the Optimizer
Runtime.
oSmartMeter: comprehensive Time-Code aware metering module (CF Chapter 6).

1.2 Main Features of the System Software
The Trinnov Processor provides all the basic functionalities expected from a digital audio processor:
routing and level settings of inputs and outputs (Audio Matrix functionality)
word clock input and output
remote control options via an Ethernet network or via GPIO commands
presets save, backup and restore
basic peak level metering of inputs and outputs
calibrated, global gain/volume adjustments
monitoring controller
This allows to integrate the Trinnov Processor into any professional studio environment and to meet
the highest standards for sound quality and system flexibility and reliability.
1.2.1 Manual Equalization
The Processor is very useful in addition to the Optimizer as it offers a comprehensive set of tools to
fine-tune the results of the automated correction. This is usually done by using a separate acoustic
measurements system to measure the results of the automatic optimization and improve them.
Two different tools are offered:
State-of-the-art FIR EQ: based on Finite Impulse Response filters, the Optimizer's FIR EQ
allows for accurate equalization without introducing additional phase problems.
1/3-octave EQ: 31 band Graphic Equalizers are also provided in order to support established
methodologies and standards.
1.2.2 Active Crossovers
The Processor features 2-way, 3-way and 4-way active crossovers. Depending on the chosen audio
interface, these crossovers may be used on up to 64 output channels (MADI). This makes Trinnov
processors a comprehensive equalization and crossover solution for high-end sound systems.
1.2.3 DRC/Submixes
The DRC/Submixes complete the list of features of our integrated monitoring solution for professional
applications. These features combined allow for emulating end-viewer listening conditions. It
consists of a Dynamic Range Control as well as a flexible downmix system.
1.3 Main Features of the Optimizer module
The Optimizer Runtime and the Optimizer Toolbox are complementary. As a whole, we simply call it
the Optimizer module. Its main features are as follows.
1.3.1 Level and Time Alignment
Based on its own acoustic measurements, the Optimizer automatically aligns the relative levels of
each loudspeaker, and applies delays to time-align the system. This can be disabled in the Optimizer

Reference Manual –Software version - 3.8 Trinnov Audio. All rights reserved.
13
Settings/Runtime page, and may be configured separately for the front and surround loudspeakers in
the Optimizer Settings/Settings/Advanced Settings page.
The Optimizer also calibrate the absolute level of the system.
1.4 Automatic Optimization
The Optimizer uses state-of-the-art time-frequency algorithms to analyse calibration measurements
and uses specific methods to compensate for direct sound, first reflections, late
reflections/reverberation and room modes. All the subtlety of the Optimizer resides in knowing which
defects may be corrected without creating additional problems.
Improved Phase Response: the Optimizer corrects the frequency response of the speakers,
both in amplitude and phase. This means that the Optimizer corrects both the tonal balance to
obtain a neutral timbre for every speaker and it also works in the time domain to achieve a high
resolution stereophonic image with well-focused phantom sources.
Target Curves: the Optimizer automatically defines the filters that will achieve the required
frequency response defined by a target curve. This is particularly useful in Film Studios in order
to comply with the X-Curve SMPTE and ISO standards. Phase and Group Delay targets may
also be defined, making the Optimizer a unique tool for sound system designers.
Fine-tuning options: the Optimizer provides over 12 different parameters, such as maximum
boost/attenuation, to customize the behaviour of the room correction algorithms. This opens
many possibilities for fine-tuning the sound according to loudspeaker capabilities and
listening tests.
1.4.1 Loudspeaker Positions Remapping
Thanks to its measurement probe with 4 capsules, the Optimizer determines in 3D the relative position
of each loudspeaker. From the Input Format setting, the Optimizer knows the reference loudspeaker
positions defined by the standard for the target system, for example ITU 775. The Optimizer computes
the remapping matrix that must be applied to the input signal to create the same acoustic field that
would be obtained if the speakers were positioned correctly.
For an in-depth description of Trinnov’s remapping technology, please read the AES Paper 6375,
Reproducing Multichannel Sound on Any Speaker Layout, available in the download section of our
website at www.trinnov.com.
1.5 Main Features of the SmartMeter module
The SmartMeter is a time code-aware metering system. It includes a set of instruments and features
that make it one of the most cost-efficient and innovative solution on the market, saving precious time
during mixing when constrained to the new Loudness recommendation in any kind of environment.
Synchronizing the measurement to an external time code also allows for unique possibilities such as
measurement session recall and real-time alerts system integrated with every instrument.

2.1.1 Power on
Important Note: don’t forget that the speakers/amplifiers should always be powered up last.
Every Trinnov processors have power switches on both back panel and front panel.
The back panel power switch always needs to be pressed first to supply the processor with electricity.
The front power button shall then be used to start the processor. It should illuminate after a few
seconds.
Note:
Trinnov 2U chassis have a permanent power switch.
Trinnov 4U chassis have a momentary power switch.
The optional 4U chassis with built-in touch screen has a separate power switch, on the left side of the
front panel and is labeled “PW”. The menu button shows the OSD for LCD screen setup. The reset
function can be used to recall factory settings.
2.1.2 Shutdown
Shutdown differs depending on your Processor model:
Processors mounted in the Trinnov 2U chassis require pushing the power button only once to
initiate normal shut down.
The 4U processors shut down procedure requires pushing the power button a first time then a
second time or selecting the "yes" option on the graphical interface.
About pops coming off the loudspeakers at power on and shutdown:
RME analog boards generate pops, therefore, you should switch the monitors on after the
Trinnov is powered on. And you should power the monitors off before shutting down the
Trinnov.
The Trinnov analog boards are equipped with relays on the outputs to prevent electrical
discharges and protect your speakers. Shutting down the Optimizer does no longer require
switching off amplifiers.
Note: it is not recommended to cut the AC power (back panel), as the system saves several "last used"
settings.

2.2 User Interface
Trinnov Processors open architecture offers a variety of solutions to access the user interface:
from an external monitor with a keyboard and a mouse,
via an external touch screen (recommended with the SmartMeter),
from a VNC Client running on remote device (laptop, smartphone or tablet) connected through
the network to the Trinnov Processor
Important Note: because of network latency, using VNC is not recommended for metering
purpose.
2.2.1 Multiview Mode
The Multiview is an optional display mode for the SmartMeter that divides the graphical user interface
in 4 zones. The user can configure its own layout by affecting any measurement and control
instrument to each of these zones.

2.2.2 Using an external display, mouse and keyboard
Trinnov Processors have VGA (and/or DVI) and PS2/USB ports at the back for standard PC monitor
and mouse/keyboard use and may be used with KVM (Keyboard Video Mouse) extenders (available
as an option). In this way, one has comprehensive, remote access to all the functionalities of the
Processor.
Using an external display is also the easiest way to find the IP address of the processor that is needed
to use VNC (Setup/System Status).

2.2.3 Using an external touch screen
External 8”, 12" or 17” touch screens (with up to 3m cables) are available as an option. They can also
be connected via a KVM system with full USB capability for an extension of more than 30 meters. For
extension below 30 meters, a long VGA cable and a simple USB extender on CAT5 cable (available as
an option) may be used.
The 17" touch screen use is optimal with the SmartMeter on MC Processors in Multiview mode.
17" touch screen
Important Note: Most KVM systems can only handle PID devices (i.e. mouse and keyboards)
but do not support USB touch screens. For the KVM system to support an external touch
screen, it must support full USB connectivity, including, for example, memory storage
devices. For further information regarding compatibility, please contact Trinnov Technical
Support.
Touchscreen Calibration
If you want to control your Optimizer with an external touchscreen, it first needs to be calibrated
properly. The procedure is the same for 8”, 12" and 17” touchscreens:
-Proceed as instructed in chapter 3.4.1 to display the startup menu and select Touchscreen
calibration.
-Use the provided stylus to click on the center of each mark.
-Check calibration is OK by moving the cursor using the touchscreen. Pay particular attention
to the corners.
-If Calibration is OK, press Enter. If not, press Escape to perform a new calibration.
Please note: after the Calibration Process, the processor will reboot using the same startup mode than
during the previous startup.

2.2.4 Using a VNC Client through the local network
Trinnov Processors have a built-in VNC Server that allow you to fully control the processor from any
VNC client host device over the network.
VNC is a graphical desktop sharing system that transmits the keyboard and mouse events from one
computer (server) to another (client), relaying the graphical screen updates back in the other direction,
over a network.
In other words, VNC provides full control of the processor from a laptop (PC, Mac or Linux),
smartphone or tablet (iOS, Android, Blackberry, Nokia...)
VNC control from Windows XP VNC control from Mac OS X
You can find different VNC Clients/Viewer on the Internet. As examples, we've chosen "TightVNC" for
Windows 7 and "Chicken of the VNC" for Mac OS X.

As you launch the VNC client, you will attempt to establish a connection to the server. The VNC Client
will ask you the server address and a password:
The server address is IP address of the Trinnov Processor. You will find it in the Setup/Network
page:
Note (advanced user): You can also find the IP address in the DHCP Client list of your
router/set-top box administration page
a password which consists of:
oThe 6 digits serial number for TAC-based Processors (Trinnov Audio Core) labeled on
the back panel.
oThe “Product ID” number displayed in the Help/About page:
7 digits for TAC based units.
6 digits for RME based units.
2.2.5 Screenshots
Screenshots of the graphical interface can be stored during operation by pressing the “print screen”
key on a keyboard connected to the unit. These files then can be downloaded to a USB stick or through
Ethernet (cf chapter 4.3).
