To ensure maximum shielding properties.
Case Apollo DAC designed to achieve vibration damping and mechanically extremely robust construction. Special attention was also paid to ensure maximum sealing properties. We developed a special self-locking of the inclined-plane system of locks, which ensures low contact resistance between the bodywork and the reflection of sound waves at the boundaries of the elements.
The material was selected as aluminum-magnesium alloy with high damping decrement of the oscillations and the low propagation speed of sound waves. The elements of the case are manufactured with precision equipment by milling from a solid plate with subsequent ultrasonic quality control on the absence of internal defects. For additional vibration protection Assembly of printed circuit boards and unit transformers produced on a massive monolithic plate with a thickness of 12 mm of the same alloy.
The point of location of the support legs is determined by computer modeling the interference pattern of sound waves propagating in the bottom of the case for different frequencies.
