Audison Voce AV 5.1k
The Audison AV 5.1 K car amplifier has been with us for a while now. It is enjoying a surge in popularity due to new interest in Hi Res audio listening (previously known as HD audio).
Hi Res audio has taken a while to gain traction. Traditional Hi Fi system messaging has very much focussed around the back-end of an audio system, especially speakers. Amplifiers were previously thought of as simply a means to make the music in your car louder.
With the huge increase in Hi Res streaming services, folk have focussed for a while on the front-end or source units. No longer hamstrung by restrictive CD quality, music sources have demonstrated how much more detail even familiar music can reveal when a Hi Res source is used.
Amplification becomes extremely important once one moves to a totally digital front-end. Source to signal processor was the first link in the chain to get attention. This not only helps to preserve bit-perfect quality but is the best thing one can do to protect delicate audio signals when moving them around a motor vehicle.
A poor amplifier can undo all of this good work. Many “average” amplifiers can flatten dynamic sources and become confused by the amount of detailed information, especially in the mid-range. The Audison Voce AV 5.1k delivers exemplary performance when handling Hi Res input from clean sources.
The addition of an Audison Voce AV bit In module allows the amplifier to accept digital inputs directly from Audison bit Processors or bit Play HD. In this instance, an Audison developed digital bus known as AD link is used to link pieces of digital Hi Res equipment together to make the resulting signal pure and robust all the way to final amplification stage. However, this is seen by some installers as unnecessary due to the sheer quality of the Audison Voce AV 5.1k amplifier even with analogue inputs.
The versatility and final quality of the amplifier comes down to the inclusion of two class A channels, two class AB channels and a mighty class D channel for driving subwoofers. Having this choice of amplification all in one package makes the installers job far easier than with discrete amplifiers. Only one power supply is required and the one-box solution is an absolute boon when working on vehicles where storage space is at a premium.

The amplifier brings the very best out of any speakers connected to it, but is perfectly suited to speakers of higher quality such as Audison Voce, Audison Thesis and beyond.
In use, the amplifier handles all genres. Busy orchestral pieces are delivered with separation to die for. This results in an ability for listeners to pick out even the quietest instruments alongside thundering Timpani or rude Brass. The same can be said for highly dynamic and difficult to reproduce rock music.
If Hi Res music sources are your daily pleasure then you cannot go wrong with a system with an Audison AV 5.1k at its beating heart.
