7. Headphone Output Level 1 & 2 – These rotary encoders control the levels of the

individual headphone outputs. These controls are independent of output levels.

8. S/PDIF Input and Output Indicator LEDs – The green S/PDIF In LED will glow

steadily to indicate the presence of a valid S/PDIF signal at the active S/PDIF

input. The green S/PDIF Out LED will glow steadily to indicate the presence of a

valid S/PDIF signal at the S/PDIF output(s). The active S/PDIF input is selected in

the Control Panel, with coaxial S/PDIF being the default selection.

NOTE: When S/PDIF is selected for the digital output port, S/PDIF signals will be sent to

both the optical and coaxial outputs.

9. ADAT Input and Output Indicator LEDs – The green ADAT In LED will glow

steadily to indicate the presence of a valid ADAT signal at the optical input. The

green ADAT Out LED will glow steadily to indicate the presence of a valid ADAT

signal at the optical output.

10. Line Input and Output Indicator LEDs – The green Line Input LEDs will light at -

30dB and above. The green Line Output LEDs will light at -60dB and above.

11. A/B Status Indicator LED – This LED indicates the currently selected mode of the

A/B Switch. LED off = A, and LED on = B. In its default setting, the A/B switch

controls Direct Monitoring On/Off, but may be configured as a headphone source

switch (see the “Hardware Page” section, “A/B Source Switching” for more information, and

also “Using the A/B Selector Switch).

12. A/B Selector Switch – This momentary switch turns Direct Monitoring on and off, and may

be used manually or controlled by ASIO Direct Monitoring (see your audio application’s

documentation). LED off (A) = DM off, and LED on (B) = DM on. This switch can also be

programmed to select the monitor source sent to the headphone outputs, in conjunction with

the Headphone Source settings on the hardware page of the Control Panel.

13. Level Controller – The Level controller is a rotary encoder that is set by default to

control the output level of the FireWire 1814’s analog outputs. It can be assigned to

any group of mixer or output faders in the FireWire 1814’s software Control Panel.

The available selections are:

A. SW Return Bus – Levels of sw rtn 1-4

B. Output – Levels of analog 1/2 out; this is the default selection

C. Input – Levels of the eight analog, eight ADAT, or L/R S/PDIF digital inputs

D. Aux Send – Levels of the L and R virtual Aux Send buses

14. Power LED – The Blue Power LED glows steadily when power is applied to the

FireWire 1814.

15. Power Switch – This push-on, push-off power switch turns the FireWire 1814 on

and off.

16. Phantom Power LED – The red phantom power indicator LED will light solid when the

Phantom Power Switch is in the “in” position, sending phantom power to both XLR mic input

channels 1 & 2.

17. Phantom Power Switch – This push-on, push-off switch turns the phantom power on

and off.
