Trinnov Audio Amplitude8
Built for reference-scale cinema and music, the Amplitude8 delivers tremendous drive, explosive dynamics and remarkably composed control across eight channels. LowBeats found it equally convincing with dense orchestral climaxes and exposed vocals, retaining fine detail, separation and imaging under sustained demand. Its dual-supply authority makes demanding low-impedance speaker systems feel effortlessly covered.

What Reviewers Are Saying
SOUND QUALITY PERFORMANCE 90/100
The available listening report describes an unusually forceful yet finely detailed multichannel amplifier, remaining composed when demanding material and high levels would overwhelm typical AV receivers. Its most clearly documented strengths are power, dynamic contrast and maintaining musical separation under pressure; the review is less specific about its tonal balance.
Transparency Resolution
91/100
LowBeats found the Amplitude8 impressive for detail as well as impact, noting that it could shift from dense orchestral and big-band passages to placing Ella Fitzgerald's voice clearly in focus. The reviewer also attributes a pleasingly fine level of detail to the amplifier stages even during sustained high-output operation.
Tonal Balance Musicality
80/100
The review portrays the presentation as engaging across both large-scale music and solo vocal material, rather than merely spectacular or blunt. It says little, however, about tonal color, warmth, treble character or timbral naturalness over extended listening.
Dynamics
96/100
LowBeats reports tremendous drive and an especially satisfying balance of macro- and microdynamics. With 375 watts available to all eight channels simultaneously into 4 ohms, the amplifier reportedly never runs out of breath on powerful orchestral peaks or sustained high-level passages.
Soundstage Imaging
91/100
During dramatic climaxes, the Amplitude8 was said to continue increasing its output without losing differentiation or imaging. That ability to preserve separation in dense, loud material is particularly valuable in a multichannel system.
Assessments of Build Quality, Usability, and Overall Propositions.
Build Quality
93/100
This is a very substantial 48kg eight-channel design, built around two large toroidal power supplies and extensive heatsinking for thermal stability. Its engineering is also well suited to demanding installations, with load-stable operation down to 2 ohms, balanced XLR inputs on every channel, five-way binding posts and 12V trigger input/output.
Value for Money
85/100
At roughly $12,750 to $16,500, the Amplitude8 is a serious investment, though it combines eight powerful channels in one chassis and is specified for difficult loads. The available review does not directly assess whether it outperforms competing amplifiers for the asking price.

Manufacturer's Description — Trinnov Audio
Achieving maximum performance in an Altitude32 theater requires equally proficient amplification. That is the reason we created the Amplitude8 power amplifier. Optimized to work with Trinnov processors, it integrates seamlessly with the Altitude both visually and technically, and in operation creates a powerful three-dimensional soundstage, with huge dynamic range and bass impact to equal and exceed that of the best commercial theaters.
State of the Art Performance
The Hypex Ncore® NC1200 class-D power module represents the state-of-the-art for audiophile performance, with unparalleled clarity, musicality and resolution. It features the industry’s lowest distortion and noise specifications, and its performance is frequency-independent. You’ll find it in the finest audiophile monoblocks, and that’s why we use it in the Amplitude8.
The audio performance of the Amplitude satisfies the most demanding audiophiles, and when watching movies, you’ll find its silent background noise and enormous dynamic range ensures you’ll hear every detail in the quietest passages and clean, undistorted output and impact when the soundtrack is at its highest loudness levels.
Feel the Power
Think of this 8-channel class-D power amplifier as two high-output four-channel amplifiers on a single chassis, each with its own power supply.
Each linear power supply is built around a separate heavy-duty toroidal power transformer, enabling every module of the Amplitude to deliver 225W into 8 ohms, 375W into 4 ohms and 500W into 2 ohms.
In fact, the Amplitude requires two AC power connections.
Perfect Integration
We perfectly matched the input level of the Amplitude to the output level of the Altitude32, optimizing the system’s dynamic range. By doing this, we are able to decrease the background noise of the system by a highly significant 6 to 8 dB, a benefit unavailable when using other amplifiers.
Why is this so important? Immersive audio systems have a large number of speakers, and each is a potential source of background noise, especially when the system has high-sensitivity speakers. A silent background ensures that low-level sounds critical to a soundtrack will not be obscured.
Magnificent Impression
The physical integration of the Amplitude and your Altitude processor has also been taken into account. You can take the conventional approach with eight independent XLR input cables, or elegantly simplify your rack installation with a single D-Sub cable that handles all 8 channels.
Convection cooled, the Amplitude8 operates silently, without internal fans, making it ideal for use when the equipment rack is located inside the theater. Once installed, the Amplitude8 front panel complements the look of the Altitude32, creating a magnificent impression in your home theater rack.
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.
