The power amplifiers OVATION MA 8.2 and SA 8.2 deliver nearly any desired power level even into critical loudspeakers without loss of control over the loudspeaker. Far over 1200 Watts into 4 Ohms with the MA 8.2 and over 600 Watts with the SA 8.2 are surely sufficient for reproduction of any kind of music, even when listening at original sound levels. Nevertheless, both amplifiers can also play at moderate levels without loosing precision or missing even finest details and the may reproduce also the intimate atmosphere of a i.e. chamber orchestras.
The new generation of the OVATION MA 8.2 and SA 8.2 have been developed by music lovers for music lovers to satisfy even highest demands on reproduction of music. Forget about noise and distortion and enjoy it’s warm and powerful music reproduction – regardless which loudspeaker you use, regardless which music style you prefer and whatever volume you like best. Its excellent musical quality comes together with a very worthy finish: The case is totally made of polished and anodized aluminum. The power transformers inside (2 x 1000 VA, 2 x 120 VA) are mounted into a shielding case that ensures no mechanical hum or electrical stray fields can influence the electronic circuitry of the amplifiers.
The power supply consists of two 200.000 µF Capacitor banks. The MA 8.2 power amplifier itself is a balanced construction. That means two amplifiers in bridge connection. Each of the power amps has its own transformer and capacitor bank. The amplifiers use 24 output-FETs each and thus are able to deliver over 180 amperes permanently – if needed. The SA 8.2 is the single ended version thereof. The input circuitry is also a balanced construction and offers RCA-Cinch and as well balanced XLR inputs. Besides that we have built in a brilliant blue VF display which informs you about the actual power (power bar) and the peak power (numeric). It is also useful to make settings via the intuitive menu system: Configuring the display (power bar & value display, peak power only and display off), setting the display brightness, setting the operating mode (permanent, trigger, auto, remote from preamp) and setting the actual speaker impedance (8, 4, 2 Ohms).
In the .2 Version of the awarded OVATION amplifiers we have implemented numerous amendments and improvements to increase the performance of these outstanding amps once more. The power supply has been reworked to meet government regulations (Stand-by < 0,5W) and two newly designed main transformers are utilized, one transformer per side resp. per side. On top of that the inner cabling was improved and altered and amended to the increased power and sonic spectrum. Last but not least, the MA 8.2 and SA 8.2now feature an enlarged Class-A range and the power amplifier section works on a higher voltage supplied from the power supplies. The circuit boards all are plated with extra thick copper conductor leads (100µm) and additionally they are completely gold covered to make them inherent to environmental influences.
Linked to an adequate AVM preamplifier, the OVATION power amplifiers MA 8.2 and SA 8.2 may be switched on and off automatically. Together with AVM preamplifiers, additional control functions may be applied from the preamp into the power amps i.e. the display intensity may be changed. For doing so control codes are being sent to the power amp with microscopic levels and at very high carrier frequencies. This way the control over the power amps may be performed without additional cables being necessary.
