The Analog Input Box (AIB) allows connection of sensors (battery or mains driven) or the attachment of any signal generating products. All the inputs are processed differential. For each signal which are connected to the AIB box, an AIB channel is required. The Input range of the AIB is +/-1 Volt (2 Volt peak to peak). Standard the AIB is equipped with 8 channels (can be ordered with a maximum of 32 channels). The speedmode switch on the frontpanel of the AIB should always be set to 8. With an AIB, the ActiveTwo EEG only works at speedmode 4. Package comes with the AIB box (8 channels) fitted with a D-SUB 37 socket, the power socket, an IN/OUT socket for the connection of the optical fibers; 1 x optical fiber and 1 x power supply. Please note: the Analog Input Box can be internally switched to 2-0 Volt. Select number of input channels, includes fitting of channels.
