Marton\u00a0‘s new\u00a0Opusculum\u00a0Omni\u00a0dual mono amplifier\u00a0offers maximum electronic and mechanical symmetry. The device is designed in such a way that it can act as three independent devices – an integrated stereo amplifier, a stereo power amplifier and a monoblock. This is what the developers say.<\/p>\n

The design uses a powerful battery of capacitors with a \u201clong service life\u201d – 528,000 \u03bcF and several separate power stages built on low-noise stabilization systems. The power supply design ensures free flow of energy from the powerful capacitor bank to the final stage.<\/p>\n

The entire amplifier housing (except for the shielded transformer housing) is made of non-magnetic materials and is resistant to electromagnetic and radio frequency interference. The case rests on high-quality anti-vibration feet – the\u00a0GigaWatt Rolling-Ball\u00a0isolation system .<\/p>\n

Heavy-duty CNC-milled heatsinks and perforated top and bottom covers facilitate heat transfer and are\u00a0CE\u00a0and\u00a0OHS\u00a0compliant .<\/p>\n

The 1000 VA toroidal transformer, dedicated exclusively to audio circuits, is mechanically isolated from the housing. To ensure maximum isolation from vibrations (internal and external), the transformer was filled with a special anti-vibration mass.<\/p>\n<\/div>\n<\/div>\n

For digital systems and control, a separate EU toroidal transformer was used. It is also anti-vibration isolated and does not create unwanted interference. This transformer powers the digital circuitry that controls the amplifier.<\/p>\n

\"Image\"All electronic circuits are assembled on printed circuit boards made of laminate 2-3 mm thick and a layer of copper 120 microns thick coated with a precious metal, ensuring maximum current propagation speed. All connections are soldered with an alloy of tin and silver. The final power amplification stage consists of 28\u00a0Sanken\u00a0bipolar power transistors operating in a push-pull circuit. The input signals to the amplifier are electrically isolated from the power stage.<\/p>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
