• Power Adaptor Input. This is where you plug the provide IEC power cable into the FireStudio Project.
• Power Switch. Push the top part of the switch to turn your FireStudio Project on ( | ). Push the
bottom part of the switch to turn your FireStudio Project off ( O ).
• FireWire Ports. There are two standard 6-pin FireWire ports on the back of the FireStudio Project.
Either (and only one) should be used to connect your FireStudio Project to a vacant FireWire port on
your computer. If your computer has a 4-pin connector (commonly found on laptops), you will need a 4
to 6-pin connector to connect your FireStudio Project to your computer.
Use the ‘extra’ FireWire port to connect additional FireWire devices in such as external Hard Drives.
• S/PDIF In and Out Jacks. These allow the FireStudio Project to receive and transmit audio from other
digital audio devices. The S/PDIF standard allows two channels of audio to be transmitted at rates up
to 24bit/96kHz. The S/PDIF input also allows the FireStudio Project to receive Word Clock – the
synchronizing signal indicating the sampling frequency or rate of sample words over a digital interface.
You should select ‘S/PDIF’ as the Clock Source in the FireControl when using the S/PDIF input.
• MIDI In and Out Ports. MIDI stands for “Musical Instrument Digital Interface”. However, the MIDI
standard goes well beyond just instrumentation and sequencing. The MIDI inputs and outputs allow
connection and/or communication with external MIDI equipment. One function of this port is MIDI
programming. These can also be used for MMC (MIDI Machine Control) and MTC (MIDI Time Code).
