Once inputs and outputs have been set they can be saved to memory and recalled later. Up to 4
individual input/output routes can be saved. The route will remain in memory until a new route has
been saved to that memory number or the matrix has been factory reset.
Once an input/output route has been saved, it can be loaded at any time.

When the matrix is completely connected and turned on it will load the default EDID, which is the
highest common native resolution of the devices. (i.e. In the diagram below the default would be
720p with 2ch audio. Multi-channel audio and 3D are not enabled on internal mode, unless
all devices have these features.)

On default, all devices in the diagram will work at 720p. If a device is not syncing or a different
resolution is required, internal EDID or EDID copy and load should resolve these issues. The
PRO3HD can copy up to 4 EDIDs to memory.
