Product Features

Unique Decoding and Rendering

Dolby Atmos

The Altitude32 remains the only AV Processor on the market capable of decoding and rendering Dolby Atmos Home content in its full 24.x.10 channel count.

It's been capable of doing so since 2015, years before competition.

With the Altitude48Ext and its extra processing power, we can support up to 64 outputs.


In 2019, Trinnov worked closely with DTS to introduce DTS:X Pro to the consumer market.

Altitude owners enjoyed this major upgrade a year before our competitors could offer it.

The Altitude32 is the only processor capable of native rendering and upmixing with DTS's full count of 30.2 channels, delivering the highest spatial resolution with all content.



The founders of Trinnov and Auro-Technologies know each other well, having been at the forefront of immersive sound research and development dating back to the early 2000s.

Auro-3D, up to 13.1 channel configuration has been available on the Altitude32 since 2015. The popular Auro-Matic upmixer is also supported for all inputs.

Immersive Sound Unleashed

In a league of its own, the Altitude32 has no peer when it comes to immersive sound decoding and playback.

Our pure, uncompromised implementation of 3D Codecs, made possible through our own software, enabled us to deliver the full specifications and channel count of both Dolby Atmos
and DTS:X Pro years ahead of the competition.

Altitude owners enjoy a unique feature available on no other product:

The Dolby Atmos Object Viewer provides the user with a real-time view of the location and movement of sound objects in 3D space for all Atmos content.

Unique Bass Management

The Bass Management solution in the Altitude gives users the most sophisticated tool available for managing low frequencies.

Complete flexibility regarding high and low pass frequencies, filter types and filter slopes is just the beginning. The low frequency content of any channel can be fed to any combination of subwoofers, and there is no limitation to the number of subwoofer channels other than the number of available outputs.

Going further, our unique intermediate bass management system is ideal for immersive systems using smaller height channel speakers. It can redirect low frequencies not just to subwoofers, but from a speaker with limited bass capability to the closest, more-capable speaker, before sending the lowest frequencies to the subs.

Trinnov Optimizer

Our world-renowned Loudspeaker/Room Optimizer is recognized as best-in-class by users and reviewers across the professional, commercial cinema, and high-end home audio worlds. Introduced to the pro audio market in 2006, its revolutionary solution was quickly embraced by many of the most demanding music, broadcast, and post-production sound engineers.

Optimizer technology is now used in nearly 2,000 studios across the globe with nearly 10,000 high-performance installations worldwide.

This same technology, enhanced and refined over the years, is at the heart of the Altitude. To this day, the Optimizer remains the most powerful and flexible calibration system available.



This feature increases the capacity of each Altitude32 model by extra discrete channel decoding and Optimization.

By enabling the use of 4x AES/EBU outputs in addition to the analog outputs, Trinnov further unleashed the potential of the Altitude32.

This update comes free of charge to all Altitude32 owners who can now add extra subwoofers or channels to their system to increase its performance.

Unique Remapping Technology

In real-world rooms, we can’t always place speakers where we should. And in any case, Dolby, DTS, and Auro each have a different idea where they should go. Trinnov’s exclusive, patented Remapping is the only solution.

During calibration, Trinnov’s unique 3D microphone precisely maps the location of each loudspeaker in the room regarding distance, azimuth and elevation. 

When decoding a particular soundtrack, we know the intended placement of each of the various sound elements. Then Remapping, taking the reality of the room into account, ‘remaps’ errant sounds to the proper locations by using adjacent speakers and the principle of stereo imaging.

HDMI Unbound


HDMI and its evolving standards continue to create challenges for manufacturers, integrators, and end users. Rest assured that the Altitude philosophy of sustainability applies to HDMI.  The Altitude’s modular hardware design ensures that future developments of the HDMI standard will not make the processor obsolete. All Altitudes use an exclusive HDMI 2.1 Board, developed in partnership with Cypress Technology

Today, our proprietary software platform enables users to monitor and analyze all incoming and outgoing HDMI data directly on the Altitude, in addition to providing unique tools that can address HDMI  incompatibility issues.

Remote Access

Through its Paris-based server, Trinnov enables remote access to any processor connected to the Internet.

Integrators can remotely access each processor they have installed, with full control of all parameters, thus eliminating the need to be on site to adjust a customer’s system or to diagnose problems.

In addition, the Trinnov factory support team, based in the United States and France, and acknowledged as among the best in the industry, also has remote access to provide higher-level remote assistance and troubleshooting.

The most awarded sound processor in the industry

The Cinema Designer

The Cinema Designer (TCD) is a powerful online design tool that allows integrators and system designers to create not only technically impeccable cinema designs in a matter of minutes, but also a complete set of support documents and aesthetic room renderings.

Trinnov Altitude processors and Amplitude amplifiers are fully supported in the TCD software, enabling designers to integrate the Altitude in the most complex speaker layouts in a matter of minutes.

TCD integrates Trinnov's exclusive recommendation for speaker placement by default.

Step by Step Wizard


First-time users will find the Altitude Wizard an invaluable tool for setup and calibration.

This onboard software guides the integrator through the entire process, step-by-step. From configuring the speaker layout, setting up the input and outputs, to the microphone setup and calibration, the Wizard greatly simplifies the process of getting the Altitude up and running.

    Besides exceptional audio performances, the Altitude32 is the only processor able to handle immersive formats’ incompatible speaker positions. The level of details of its audio calibration is unequaled. But most of all, it is future-proof. We don’t know yet if we can call it « a lifetime processor, » but it should most certainly accompany its happy owner through cinematic and musical adventures for a very long time.
