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.
