AMPLIFIERS - REQUIREMENTS AND OPTIONS
A particularly misunderstood part of the choice of audio equipment is the category of audio amplifiers, as we encounter many cases where the interested party has purchased speakers with high quality features, giving little importance to the capabilities of the amplifier, thus receiving the minimum of its capabilities. audio equipment. Other times we choose amplifiers ignoring the environmental conditions and their operation, as a result of which we constantly face issues of malfunctions, and we have to either temporarily replace them in order to repair them, or replace them with the appropriate material, spending extra money. unnecessarily.

Therefore, when buying reinforcing devices we should pay attention to both their quality of construction and technical characteristics such as their power (RMS power rating), which should possibly reach twice the price listed as rated or average power of the speakers it is called to drive (more detailed information in the technical leaflets of our website). Also, we need to know the type of speakers that it is called to drive, ie if they are speakers that belong to the Commercial category and therefore have a transformer and require an amplifier that works at 100V, or belong to one of the other categories of simple ohms speakers. Finally, an important factor is the degree of so-called Headroom, which marks the difference between the maximum power that our amplifier can deliver without distortion, and the average rated power of the device. The higher this rating is, the less likely it is that the amplifier will be distorted in the output signal and will therefore overheat and damage our speakers as well.

It is worth mentioning at this point that in many cases of audio coverage of a multi-space, we encounter the need to install an amplifier with multiple audio outputs, in order to avoid the volume of multiple machines and to reduce the relevant cost when buying them. In this case we must pay special attention to both the technical characteristics and the adequacy of outputs and consequently separate sound control zones in the individual spaces.

So this is one of the most serious decisions we have to make, when we need to procure the necessary reinforcements in order to effectively equip our system and invest our space in the best way.
