Because immune 'to raise common side turntable rumble, caused by elf tire edge of the border. turntable, an earlier version of the system, binaural Cook (described below In Stereo) as well try. But for not for high fidelity stereo. (At least not yet).
This system is adjusted vertically in a small area near the center. Of the disc for the base of the program started over a half plate to avoid distortion in – Groove, and adjusting for the treble side of In large projects from the edge of the disc halfway through the highs for the program. This means that the next turntable rumble will be filtered out high-pitched electronics. The crossover network of static and crackling highs and may be filtered out from the base by the same process. . [Citation needed].

Production, marketing by RCA Victor as "Dynaflex" process (125 g), considered low by most storage. Most pressing is the combination platter. To 70 percent pure vinyl and 30 percent of recycled vinyl.
New "virgin" or "heavy / Page (180,220 g) vinyl is commonly used for modern "audiophile" version of Onyx in all categories. Many want to accumulate 180 Onyx album. g, and they receive better sound than normal vinyl.
