Auray IP-S Isolation Pad for Studio Monitor (Small, Single)

The small IP-S Isolation Pad from Auray is a monitor speaker isolation pad made from high-density acoustic foam. It is designed to decouple your monitor speakers from its resting surface by absorbing the monitor's vibrations. This stops reverberation through the desk or speaker stands, therefore preventing unwanted resonance. Removing these unwelcome vibrations results in greater depth of field, tighter low end and transient response, and a higher level of detail across the frequency spectrum.

Set at Three Different Angles
Up position: Angle your speakers up for desktop use
Down position: Angle your speakers down for use on a monitor bridge or shelf
Flat position: Flip the pads upside down to set your speakers flat on adjustable speaker stands

Does it require an external power supply when usin

Does it require an external power supply when using it with and iPad pro?
Asked by: Mark
Yes, the PreSonus Quantum ES 4 USB-C Audio Interface will require use of an external power supply when connected to an iPad Pro, as mobile devices often cannot provide enough bus power through a single USB-C connection. You will need to use a 5V DC, 2.6A (approximately 13W) power source connected to the aux port on the ES 4, which can be a portable USB battery power bank or wall adapter.
