Rear Panel Connections; External Psu Input; S/Pdif I/O; 6-Pin Firewire 400 Ports - Focusrite Saffire LE User Manual

Rear Panel Connections

1. Line/Instrument (TRS/TS Jack) Inputs for channels 3 (below) and 4 (above)
These 1/4" Jack sockets allow a balanced or unbalanced Line level signal or an
Instrument like a Guitar or Bass to be connected. If plugging in an Instrument then
make sure that the High Gain Switch for the corresponding Input is activated within
the SaffireControl LE software. See the SaffireControl LE section for more details.

2. External PSU Input

This socket is for powering the Saffire LE using the supplied external power
supply. This is only necessary if Firewire bus powering is not available, for example
if the connected computer only has a 4-pin Firewire port.

3. S/PDIF I/O

These RCA connectors are for receiving or transmitting a consumer digital audio
(S/PDIF) signal. With the AC3 THRU switch activated in SaffireControl LE, the RCA
Output can be used to directly stream an AC3 or DTS signal from a software DVD
player to a home surround studio setup. See the Direct AC3/DTS streaming to the
RCA Output section for more details.
4. MIDI I/O
These standard MIDI ports allow MIDI data to be received from and transmitted
to external equipment, routing through your sequencer using the Saffire LE's
Firewire interfacing. 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 or rack synth's MIDI In, activating the MIDI Thru switch in the SaffireControl
LE software will enable the MIDI data to pass from the controller keyboard to the
sound module.

5. 2 6-pin Firewire 400 Ports

These ports allow connection to the computer for streaming of data and (if
connected to an identical type of Firewire port, rather than a smaller 4-pin 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.
6. 6 Balanced Line Outputs: +4dBu, TRS Jack
These sockets are Saffire LE's Analogue Outputs, labeled accordingly for
5.1 surround: Left, Right, Centre, LeftSurround, RightSurround and
LowFrequencyEffects. If recording, then connect Monitors to Outputs 1 and 2
and Headphones to the front panel socket (Outputs 3/4) and use the software
to create independent mixes for each. If mixing in surround or wanting to stream
multiple channels of audio directly to the hardware outputs from your sequencer,
then connect speakers to the relevant sockets and activate the S/CARD switch in
the SaffireControl LE software.
