Amplifier Parasound A52

Multichannel Power Amplifier Parasound A52 refers to the elite series components HALO, which completely specify the design of its facade. Polished aluminum plate champagne color with the name and logo of the company in the central part of the cracked bottom horizontal recess concealing key power-ups and a set of LEDs. Five of these are indicators for the gain of each channel, and sixth reports on the machine overheats. Given the considerable weight of the model, will be very useful carrying handle on the back. If necessary, you can buy a set of brackets for mounting the component in a standard 19-inch rack. On top of the body is worn metal housing with a plurality of vent holes. Under it, immediately behind the front panel, mounted a huge toroidal transformer, closed to minimize interference on the preamplification solid metal screen, and directly behind the transformer installed the power supply board and switching. In filters block used six tanks of 10 000 uF. Each amplifier is assembled on a single printed circuit board secured to the cast finned heatsink. Along the right wall of the housing are three such a radiator, and along the left side, respectively, two. Input stages on JFET-effect transistors (Junction Field Effect Transistors) for fully balanced circuit. At the output of each channel gain work six field (MOSFET) transistors in the output circuits provide current up to 30 A. In this case, the damping factor at the frequency of 20 Hz, the assurances of the manufacturer, more than 1,000 units, which allows the use Parasound A52 virtually any acoustic. To connect with AV-processor or receiver can be operated not only the usual interface connectors RCA, but balanced connections on connectors XLR, get rid of the interference with impressive lengths of interconnects. However, switch the input type is common, so apply a mixed connection fails. Next to the switch located input and output 12V trigger and gun control Power On and Off, which can operate in three modes - manual, when to enable or disable the amplifier will have a button on the front panel, the alarm trigger from AV-processor or receiver or depending on the presence of the useful signal at one of the inputs of the unit. In this case, it is possible to adjust the sensitivity of the machine at the entrance. Terminals for connecting the speakers - a medium-sized, gold-plated, with colored plastic nuts.

Accompanying movies Parasound A52 demonstrates true American swing, creating large-scale surround sound field. Fine, without undue straining, he fulfills the dynamic bursts of intense moments of the modern blockbuster, but at the same time and minor details of the soundtrack pays due attention. When working with the musical material is especially good at his fervent rock songs and symphonic works. The necessary scale, remove and drive the amplifier does not hold! However, the quiet chamber records are presented very natural and airy, with a gentle transfer of the smallest details and finest reverberation.
