Connecting to the Audio InterfaceBy default, the inputs and outputs are set to receive or send a +4dBu signal. Youcan switch between +4dBu and –10dBV for each individual input and output viathe console software (see “Console” section below).The FireWire ConnectorOn the rear panel of each AudioFire interface box is a pair of connectors with theFireWire symbol above them. These six-pin IEEE 1394A connectors operate at400 Mbps and are used to connect the audio interface to your computer, and toother FireWire devices. These connectors do not pass power from the computer toother FireWire devices, so other devices will require external power to function.A FireWire cable was supplied with your AudioFire product.S/PDIF (AudioFire8 only)Next to the FireWire connectors on the back of AudioFire8 is a pair of connectorslabeled S/PDIF, IN and OUT. These S/PDIF connectors are used to transmitdigital audio data between digital audio devices via an electrical signal.When connecting devices to the S/PDIF jacks, the use of standard analog RCAaudio cables is not recommended. For reliable S/PDIF operation, 75-ohm coaxial(RG59) video cables are recommended.15Connecting to the Audio Interface
