3 System Parts
The Sirius is constructed out of a number of components. The control surface, the in-output
racks and the processing power with operational software.
3.1 The Control Surface
The control surface is actually that part of a system that you interface with the most.
The Control Surface is constructed out of different system parts that can be built into studio
furniture.
It is possible to connect a maximum of two fader control units (with up to 32 faders) and a
Super Module to the main processing power unit. Every unit has its own power supply (115
volts or 230 volts) and a sub-D connector for interfacing with the In-Output (I/O) rack.
3.2 The in- output rack
This rack can be mounted in a rack system accepting 19” rack system parts. It can accept
various I/O units all to your own individual needs. The rack mountable units are taking care of
all in- output signals as well as all remote interfacing.
The main CPU that controls the entire mixer shall also be a part of this rack.
We shall discuss this in one of the next chapters in detail.
The I/O rack (including processing unit) has two power supply connectors (115V of 230V) and
three connectors (9 pin SUB-D) for interfacing with the control surfaces.
3.3 The Control Processing Unit and its software
This is the engine of the Sirius. It is here that all (audio) data is processed. Due to the fact that
the Sirius is software based, all functions can be checked in real time. All i/o’s can be routed,
inputs can be labeled, equalizers set, etc.
We will extensively explain how this works in detail in the following sections of this manual.
