M-Audio Firewire 410 User Manual page 7

•Phones – The level of the FireWire 410's headphone outputs
•Aux Send – The level of the FireWire 410's AUX SEND bus, as controlled by the Input Channel AUX SENDS in the FireWire 410 control panel
Refer to Section 11, CONTROL PANEL, for further details.
9. HEADPHONE OUTPUTS – Each of these output jacks accepts a standard 1/4" stereo TRS headphone connector. The program signal
is identical on both outputs, with individual levels regulated by the HEADPHONE LEVEL CONTROLS. The default source selection for the
headphone output is identical to line outputs 1/2. (Refer to Section 11, CONTROL PANEL, for further details.)
10. HEADPHONE LEVEL CONTROLS – Each of these potentiometers controls the output level of its associated headphone output.
11. S/PDIF IN AND OUT LEDS – The S/PDIF IN LED will glow steadily to indicate the presence of a valid S/PDIF signal at the selected S/PDIF
input. The S/PDIF IN LED will flash to indicate the presence of a valid S/PDIF signal at the incorrect S/PDIF input.
The S/PDIF OUT LED will glow steadily to indicate the presence of a valid S/PDIF signal at either S/PDIF output. (The S/PDIF output is always
sent to both the optical and coaxial outputs simultaneously.)
12. MIDI THRU SWITCH – When this switch is in the IN position, the FireWire 410's MIDI IN and MIDI OUT ports function in bypass mode;
that is, they do not require a host software application, but function as simple hardware MIDI connections. This mode can be used whether
the FireWire 410 is powered on or off.
13. POWER SWITCH AND LED – Turns the FireWire 410 on and off.
Note: When the FireWire 410 is powered OFF, the blue POWER LED will flash if it senses a valid FireWire connection to a running
computer. When the LED is flashing, the unit is in "low-power" mode, and will allow a FireWire peripheral connected to the
FireWire 410 to continue to function. You must turn the FireWire 410 ON (blue POWER LED glows steadily) for the unit to function.
14. PHANTOM POWER SWITCH AND LED – When this switch is in the IN position, +48V phantom power is supplied to both XLR inputs.
Phantom power is required for most condenser microphones.
NOTE: While most modern dynamic microphones are unaffected by phantom power, many ribbon mics and some older
dynamic microphones may be damaged if phantom power is applied to them.

15. POWER SUPPLY CONNECTOR – Connect the 12VDC 1A power supply here when using the FireWire 410 with a four-pin FireWire
connection. Use only the power supply provided with the unit or a power supply with an equivalent value.
16. MIDI IN AND MIDI OUT CONNECTORS – MIDI input and output on standard 5-pin DIN connectors. These connections will allow MIDI
information to pass directly from input to output when the MIDI THRU button is pressed.
17. FIREWIRE CONNECTORS – Dual FireWire (IEEE-1394) inputs allow you to connect one to your computer and another to an external
device. We recommend connecting only self-powered devices to these inputs. Bus powered devices may affect your audio performance.
18. S/PDIF COAXIAL IN AND OUT CONNECTORS – S/PDIF digital input and output on coaxial RCA connectors. The digital input is
selected via the FireWire 410's control panel, while the digital output will be sent to both coaxial and optical outputs. Coaxial is the default
setting in your control panel, so the coaxial input (only) is active until another selection is made.
19. S/PDIF TOSLINK IN AND OUT CONNECTORS – S/PDIF digital input and output on optical TOSLink connectors. The digital input is
selected via the FireWire 410's control panel, while the digital output will be sent to both optical and coaxial outputs.
20. LINE OUTPUTS 1 – 8 – These are unbalanced analog outputs on standard 1/4" TS connectors at 10dB line level. These outputs will
support standard two-channel stereo, as well as surround modes up to 7.1. (Your audio software must support multiple surround outputs.)
When monitoring two-channel stereo program, outputs 1 and 2 are the default outputs; any or all output pairs may be selected in the
FireWire 410's control panel. You may also use the eight outputs to send individual or grouped channels to a mixing console.
21. LINE INPUTS 1 AND 2 – These are unbalanced analog inputs on standard 1/4" TS connectors at –10dB line level. They are parallel
to the front-panel analog inputs, and are functional only when the front panel mic/line switch is in the "in" position.
