9.6 Analog Recording
For recordings via the analog inputs the corresponding record device has to be chosen (HDSP
Analog (x+x)).
The input sensitivity of the analog inputs can be adjusted using the front panel switch ANALOG
LEVEL INPUTS to meet the most often used studio levels, see chapter 22.1.
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 (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).
9.7 Digital Recording
Unlike analog soundcards which produce empty wave files (or noise) when no input signal is
present, digital I/O cards always need a valid input signal to start recording.
Taking this into account, RME added a
comprehensive I/O signal status display to
the HDSP system, 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 frequency is
recognized, it will read ‘No Lock’.
This way, configuring any suitable audio application for digital recording is simple. After select-
ing the required input, Hammerfall DSP displays the current sample frequency. This parameter
can then be changed in the application’s audio attributes (or similar) dialog.
