1. Eight balanced analogue outputs on 1/4 TRS jack, labelled 1-8
in ascending order from bottom to top
These could be used for mixing in 7.1 (or 5.1) surround so the
outputs are marked with Left, Right, Centre, LeftSurround,
RightSurround, LowFrequencyEffects, LeftCentre and RightCentre
accordingly. If using 5.1, ignore ouputs 7 and 8 (LeftCentre and
RightCentre).
2. DC power adaptor input
This means that the interface can be powered by an external PSU
if required.The most common (larger, 6 pin) type of Firewire port
can supply power, so the use of an external power supply will not
normally be necessary. However, if the connected computer/laptop
only features the smaller 4-pin Firewire connector, which cannot
supply power, then the PSU must be connected.
3.Two RCA (phono) connections
These enable a digital SPDIF signal to be inputed and outputed. As
an SPDIF signal is stereo, this enables a total of four channels to be
recorded simultaneously, for example two separate mono sources
(voice and guitar) from microphone inputs on the front panel, at
the same time as recording a stereo SPDIF signal sent from a
synthesizer, outboard with digital I/O or additional DAW.
4.Two standard 5-pin MIDI connectors
These allow MIDI data to be received from external MIDI
equipment and transmitted from the sequencer to the DAW
(Digital Audio Workstation — most likely your computer) via the
firewire connection.Alternatively, if the Saffire s MIDI In is connected
to a controller keyboard s MIDI Out and the Saffire s MIDI Out is
connected to a sound module s MIDI In, pressing the MIDI Thru
button on the front panel will enable the MIDI data to pass from
the controller keyboard to the sound module without having to
launch any sequencing software.
5.Two Firewire 400 ports
These allow connection to the computer for streaming of data and,
(if connected to an identical type of Firewire port), supply of power
to the unit. Either port can be used for this purpose, leaving the
additional port free for connecting to other Firewire equipment
(e.g. hard drives) should the Saffire be using up the only available
Firewire port on the computer.The nature of Firewire connectivity
means that chaining equipment in this way is possible and will act
as if the equipment is connected directly to the computer through
separate Firewire ports.
