A 68-pole connector (to interface with the CPU) is also to be found on this unit.
6.1.3 Power ON/OFF switch
The internal Power supply shows the power supply cord connector for accepting 115volt or 230
volts 50/60Hz.
All other units are internally connected with this unit.
6.1.4 Digital to digital unit
The digital input and output unit provides you with the ability to read several different types of
digital signals. The software allows you to choose from SPDif (Coax), Optical or AES/EBU
inputs and outputs. All outputs are giving an identical signal; so interfacing should not be a
problem.
To make life easier the Sirius has sample rate converters on all inputs. It is therefore possible
to connect signals with different sample rates or even asynchronous on different input channels
without facing any synchronization problems. The frequency range that can be dealt with can
be anything between 20kHz up to 100kHz.
The LED’s on the left side are indicating the status of the DD-unit:
Power
indicates power is present.
OK
indicates software is running.
The digital unit has four identical sections offering two input channels and two output channels.
On the top left you find the Coax input and the Coax output connector.
Beneath these two coax connectors you see two XLR connectors for interfacing with the
AES/EBU (AES3 standard). To the right you will find the optical S/PDIF interface.
The LED’s in these units indicate the status of the digital input:
Error
indicates whether synchronization is present on the digital input.
Active
indicates whether the input is in active.
