Acoustic Revive IP-2Q
input non-shorting RCA

The non-shorting termination for your RCA inputs

Made from materials such as gold plated brass and Dural, this is a plug with considerable weight, so it has excellent damping properties. Finally, vibrations are under control!
The circuit board in your equipment that holds the terminals tends to be very thin and easily influenced by vibration. By using high specific gravity and hard material for the center pin, it reinforces terminals and protects from vibration.
