Product Features

Unique Decoding and Rendering

Dolby Atmos

The Altitude16 joins the Altitude32 as the only AV Processors on the market capable of decoding and rendering Dolby Atmos Home content with any 20-channel speaker layout.

When it comes to channel count, the devil is in the details when it matters which channels are supported. Within its 20-channel capability, the Altitude16 supports any speaker layout, including multiple side surround speakers and high numbers of subwoofers.


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. It benefits not only native DTS:X playback, but also the Neural:X upmixer, which greatly improves immersive playback of traditional soundtracks, maximizing speaker usage and listening envelopment.


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 Auro-Matic upmixer, highly popular among Altitude owners for music playback is also supported for all inputs.

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.

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.

Exclusive 3D 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 of 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.

+4 Channels

This feature increases the capacity of the processor to a total of 20 discrete channel decoding and Optimization.

Combining the 16 analog outputs and 2x S/PDIF outputs of the processor, Trinnov unlocked the full potential of the Altitude16.

This update comes free of charge to all Altitude16 owners. By adding S/PDIF / Analog converters to their system, Trinnov customers can add extra subwoofers or channels to their system to increase its performance.

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.

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.

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.

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.

Award-Winning Platform

Trinnov’s exclusive, award-winning software platform is at the heart of the Altitude16. Industry organizations and publications have honored it for its new features and continuous improvements, delivered to owners at no cost. Over time, this effectively makes their Altitudes new products.

    I’ve joked at times before about being upset over having to return a piece of review gear, but more often than not, it’s just that: a light bit of fun. With the Trinnov Altitude16 Home Theater Preamp/Optimizer, though, this is no joking matter. I’m literally miffed about having to box this beast up in a few days and ship it back to its manufacturer. I’ve been to the promised land and I don’t take kindly to being kicked out.

    Trinnov has been at the forefront of 3D audio since the beginning, and that shows with the Altitude16. It’s the most sophisticated and flexible processor I’ve encountered, and while not cheap it certainly delivers the goods, creating a seamless immersive audio experience thanks to its 16-channel talents.

    The Home Theater holy grail in terms of decoding and acoustic optimization is probably named Altitude16.

    I absolutely loved Trinnov's Altitude16, which is by far the best-sounding surround sound processor I've had the privilege to use, even though I've barely scratched the surface of the processor's capabilities, this receives my highest recommendation and I'm putting my money where my mouth is.

    One more point worth mentioning, in my experience with the Altitude16, you will likely need a recalibration of your own ears to fully appreciate what a truly optimized home cinema should sound like.
