Criterias of choice

But just getting to know these models is not all. It is very important to make the right choice when buying a receiver … The range of Onkyo is quite large, and therefore it is necessary to understand what specific functionality a good device should have. The most important thing here is to decide how many amplification channels should be in the system . Not only technical perfection depends on this, but also the cost of individual systems.

A few years ago, many believed that the 5.1 standard was absolutely everything one could wish for . Times are changing, however, and the proliferation of Blu-ray quality audio has forced such concepts to redefine. The recording of seven-channel soundtracks has already become the modern standard. Even more channels are needed if you are trying to achieve surround or even more spatial sound.

Of the five-channel systems, only the most successful samples remained on the market, and they are already among the budgetary modifications of the entry class.

9 or 11 channels - solutions that will help expand the panorama using additional acoustic generators . It is worth noting that many experts disagree with their application. They believe that receivers of this level are justified only for playing 9 or 11-channel recordings. But if you plan to use the Dolby Atmos option, this is exactly the level you should focus on . The power of the receiver is always selected taking into account the area of the room and the power of the combined acoustic devices.

On average, for each square meter, a power of 25-30 watts is required. But you must additionally take into account the manufacturer's instructions regarding the area of the room. Don't seriously trust a parameter like PMPO. These are always overestimated figures.

It is imperative to evaluate the level of harmonic distortion (both THD and IMD).
