Trinnov Audio Amplitude16 16-Channel Power Amplifier Review
Table of contents
Since I just reviewed Trinnov's Altitude16 in combination with the Amplitude16, a stunning 16-channel power amplifier that's a wonderful complement to the Altitude16, I decided to give the Amplitude its own review because it is truly deserving of one.
Specifications
The Amplitude16, developed in collaboration with Denmark's ICEpower, fits two unique power supplies and 16 class-D modules into a roughly 5-inch tall, 3RU rack-mountable chassis. The amp contains LEDs on the front that display the state of each of the 16 channels, including any that are bridged, as well as an illuminated Trinnov logo that indicates whether the amp is in standby (red), booting up (green), or full power (white). These LEDs are visually appealing, but they can be turned off if you want to keep your theater as dark as possible.
The Amplitude16 is rated to drive all channels at 200 Watts into 8 ohms and 400 Watts into 4 ohms. Due to the dual power supply, the device comes with two power lines since it's basically two eight-channel amplifiers in one single chassis. Weighing in at about 45 lbs, the build quality is also quite impressive, with a full-metal chassis and a thick aluminum front plate.
You get a major benefit when combining the Amplitude16 with the Altitude16 (or Altitude32). The input level sensitivity of the Amplitude16 perfectly matches the output level of the Altitude, which maximizes system dynamic range and signal-to-noise ratio. This means a noise floor 6 to 8 dB quieter than with other amplifiers, especially important with high channel count systems.
Design
First, there are two AC power inlets, both of which are necessary regardless of whether you're operating a single amp channel or all 16 of them. It might come as a surprise to some, but there are no RCA or XLR inputs. Instead, Trinnov includes two multipin DB-25 connectors with Tascam pinouts, making it as easy as possible to wire the amp. (The amplifier would have to be larger to accommodate 16 XLR connectors.) There are 16 speaker outputs which are grouped into eight odd/even channel pairs that span the width of the rear panel, and a 12-volt trigger input/output.
When switched to the BTL position, each output group contains four binding posts and a bridging switch that combines the channels for a significant increase in power. The binding posts can accommodate bare wires, spade lugs, or banana plugs. When channels are bridged, a white band in each cluster indicates which two of the four binding posts are used to attach the speaker cable. When two channels are bridged, the front panel display displays a solid line connecting the LEDs on each channel to signify that they are connected. Single-channel output rises from 200 to 800 watts into 8 ohms or 400 to 1,000 watts into 4 ohms in bridged mode with less than 0.1% THD+N at 1kHz, which is pretty outstanding.
Setup
To set up the connection between the Altitude16 processor and Amplitude16 power amp, Trinnov provided two eight-channel DB-25 cables, which are 1.5 meters long. It only took about 15 minutes to plug in my speaker cables to the Amplitude16 and connect it to the processor.
Performance
I put the amp through its paces with "Fast Five" on a 7.2.4-channel system. It's a very dynamic, object-based soundtrack, and the Amplitude16 was the perfect component for the Altitude16s' processing and navigation. While the Dodge Chargers roar through the streets and patrol cars are pummeled by countless crashes, the film's climactic chase scene gives plenty of opportunity for all the channels to be involved. The dynamic, energetic power amplifier recreates collisions and destruction with depth and clarity, especially during the scene where the safe is dragged through the bank and absolutely demolishes it.
While the Amplitude16 completely engulfs my entire soundstage, the efficiencies provided by this Class D amp are evident, as is its potential to create massive volume with ease. It's not just a brute force of power; this amplifier produces sound with an incredibly refined and flawless delivery.
Ghost Rider's "Make us Stronger" is an electronic music bass-fest, and my subs electrified my home theater space far more than any other power amplifier I've used in the past. Not only does this track wreck havoc on my subs, but it also demonstrates the Amplitude16's ability to handle dynamics adequately. The Trinnov successfully reproduces the track's instruments without a hint of distortion.
Conclusion
The Amplitude16 sole purpose is to maximize the performance of your speakers. The amplifier itself is robust, with more power than I could ever utilize. When it comes to speaker wire installation, it is flexible and easily configurable. Trinnov's build quality is beyond exceptional. Above all, the amplifier made my speakers sound better than they ever have. Of course, this amplifier is meant for the high-end market at an MSRP of $12,500.
Nevertheless, other amps have drawbacks such as fan noise or restricted control and connectivity choices while the Amplitude16 does not. I had a lot of fun putting this amplifier through its paces, and it's definitely worth a look and listen. The Trinnov Amplitude16, like its sibling, earns a high recommendation and is an AVS Top Choice for 2023. When combined with the Altitude16, you'll be enveloped in auditory euphoria.

FAQ
What is the difference between an amplifier and a receiver?
A power amp is a stand-alone amplifier that amplifies an audio signal. The amplifier channels will send a particular amount of watts per channel to each of the audio devices connected to it, depending on the type of amplifier you pick. The amplifier you want will be determined by several parameters, including the size of the room, the sensitivity rating of the speakers, the distance you require the music to travel, and the loudness you desire. An amplifier, on the other hand, is insufficient to power your home cinema system. You will also require a preamp or a processor. An AV receiver, on the other hand, features internal amplifiers and all the amenities, such as a radio, a tuner, an equalizer, and a preamp.
How many watts of amplification do I need for home?
It all depends on your listening habits and the effectiveness of your speaker. If you want loud, uncompressed music and your speakers are 90dB efficient, 200 Watts should be enough. If you merely listen to classical or jazz music and don't expect to play it loud, as low as 50 Watts should suffice.
Do more powerful amplifiers sound better?
Absolutely, the more watts (power), the louder and clearer the speakers will sound. Slight changes in power, on the other hand, don't produce much of an audible difference. The volume would have to be doubled to hear a change (a 3dB increase). A 50 watts per channel receiver would have to be increased to 100 watts per channel before you could perceive a difference.
