It is powered from either 110Vac or 240Vac mains with no need to select the input voltage. With user text overlays and a simple file storage system that allows the user to search for files only within the user defined project name and download them from the internal 1TB SSD to a USB stick. The console is easy to use. To record simply press the central button to start and press it again to stop. All other recorder functions are accesed by a built in touchpad so if you don't have a mouse or keyboard you are not delayed, however the 2x USB sockets allow an mouse & keyboard to be attached if preferred. This console has an analogue control knob giving a smooth and precise control over small and medium RSL lamps, which is excellent for underwater camera use. Finally this console has an audio input that is recorded onto the videos, good for narrating or recording the line/record output of a diver comms box. It is not surpriseing that this console is popular with professional divers.
