4.4 File Transfer Via the USB Port

On the front panel of the amplifi er is a USB Type A port which can transfer fi les either direction between a USB fl ash drive and the amplifi er. These fi les can be of two types: A Preset file, which contains amplifi er DSP settings for a specifi c loudspeaker/ amplifi er confi guration.

A Device file, which contain all 50 presets and the current amplifi er DSP settings.

When you plug in the drive, the amplfi ier defaults to a fi le-exchange mode and is muted. Then you can load or save individual fi les. No computer is needed for this fi le transfer.
