7.1.1 Clock source
In this field you can select the type of clock you are going to use for internal synchronization.
The clock selected here shall be used in the entire system and shall be used as the overall
clock for all interfacing with outside equipment.
When you select ‘Internal’ the clock speed will be generated internally and you can further
select in the field ‘Internal clock frequency’ the requested sample rate.
In all other cases an external sample clock will be used and you have to choose the “external
clock frequency’ in another selection box.
If you want to sync to a ‘External’ clock you may need to re -sync if you apply a new sample
rate. You can simply hit the ‘Re-sync’ button.
7.1.2 Selection
In this field you can switch the option CRM Interlock on or off. When this option is set to
“interlock” it is only possible to listen to one CRM source at the time. But when not activated
a summing of CRM sources can be realized. This is also applies for the Studio input selection.
7.1.3 Generator
The Sirius has an extensive audio signal generator. You can choose out of: Pink noise, White
noise and Sine wave. This test tone generator can be switched on or off in every channel. Level
can be adjusted (0 dB is 0dB full-scale with 24 bits) as well in this menu section, but only by
way of mouse movements. There is no hardware knob available for the global setting page.
The frequency of the sine wave generator can also be set. Type the requested frequency in the
edit box and hit the SET button.
7.1.4 Metering
This section allows you to choose between reading the input signal pre or post-processing. The
channel meters can be found on the main screen and on your control surface.
The potentiometer on the right side in this box allows you to adjust the release time of all
meters of the Sirius.
The flexibility of the Sirius systems becomes clearer with the meter type selection! You are
able to select your own meter standard. You have options to choose from: Analog, Digital,
BBC and Clock.
Below you will see an overview of all these meter types:
