8.5 Analog Recording

For recordings via the analog inputs the corresponding record device has to be chosen (Fire-

face UFX II Analog (x+x)).

The input sensitivity of the rear inputs can be changed in two steps and with adjustable gain in

TotalMix (Input Channel Settings, Level), assuring the highest signal to noise ratio will be

achieved. A further optimization can be achieved by adjusting the source itself. Raise the

source’s output level until the peak level meters in TotalMix reach about –3 dB.

The level of the front-side analog inputs can be optimized via TotalMix (Input Channel Settings,

Gain), or directly at the Fireface UFX II by the key Mic/Gain and the encoders 1/2. A double

coloured signal and clip LED provides useful information about the current level state.

Further information is found in chapter 19.

It often makes sense to monitor the input signal or send it directly to the output. This can be

done at zero latency using TotalMix FX (see chapter 25).

An automated control of real-time monitoring can be achieved by Steinberg’s ASIO protocol

with RME’s ASIO drivers and all ASIO 2.0 compatible programs. When 'ASIO Direct Monitoring'

has been switched on, the input signal is routed in real-time to the output whenever a recording

is started (punch-in).

8.6 Digital Recording

Unlike analog soundcards which produce empty wave files (or noise) when no input signal is

present, digital interfaces always need a valid input signal to start recording.

Taking this into account, RME added a

comprehensive I/O signal status display to the

Fireface UFX II, showing sample frequency, lock

and sync status for every input, and several status

LEDs directly at the unit.

The sample frequency shown in the fields Clock

Mode and Input Status is useful as a quick display

of the current configuration of the unit and the

connected external equipment. If no sample fre-

quency is recognized, it will read ‘No Lock’.

This way, configuring any suitable audio application for digital recording is simple. After select-

ing the correct input, Fireface UFX II displays the current sample frequency. This parameter can

then be changed in the application’s audio attributes (or similar) dialog.
