7.2 Settings Dialog – Analog

Level

Line In

Defines the reference level of the

rear analog inputs 5-8. The

available settings are -10 dBV, +4

dBu and LoGain.

Line Out

Defines the reference level of the

rear analog outputs 1-6. The

available settings are -10 dBV, +4

dBu and HiGain.

Phones

Defines the reference level of the

analog outputs 7/8. The available

settings are -10 dBV, +4 dBu and

HiGain.

Microphone Inputs

Channel 1/2 of the Fireface 400

have digitally controlled

microphone preamps of the

highest quality. The digital control

offers a gain setting in steps of 1

dB within a range of 10 dB to 65

dB. The configuration is done

either directly at the unit via the

rotary encoder, or via the Settings

dialog's tab Analog.

The option Link simplifies the setup in case both channels shall have the same setting/values.

The current gain is displayed in dB below the fader.

In the lower range the fader jumps from 10 dB to 0 dB. This useful additional setting allows to

operate even line signals with the microphone input (up to +10 dBu).

Instrument/Line Inputs

The inputs 3 and 4 have digitally controlled preamps. They allow for an additional gain between

0 and 18 dB, in steps of 0.5 dB. The configuration is done either directly at the unit via the rotary

encoder, or via the Settings dialog's tab Analog. The option Link simplifies the setup in case

both channels shall have the same setting/values. The current gain is displayed in dB below the

fader. Further information is found in chapter 21.3.

Activate the option Inst to use inputs 3 and 4 with instruments. The input impedance is raised to

470 kOhm, the input sensitivity increases by 10 dB. Pad decreases the input sensitivity by 12

dB to prevent overload.
