Series 52 - 52/RX Mixing Console Manual
during its full life cycle.
With a 52/RX there is no need to design customer-specific firmware. However, DHD values the feedback of its partners
and customers on its products. If there is growing demand for a special feature or function, DHD will of course consider
this during its ongoing development efforts.
The basic structure of a mixing system with a 52/RX and an RM4200D DSP Frame is shown in the figure below. There are
three main function units: the Audio Engine and the Control Engine in the RM4200D DSP Frame as well as the Control
Modules in the 52/RX Mixing Console. Additionally, external systems can be connected to the Control Engine.
Basically, the system works like this:
The Audio Engine provides the signal processing for all audio signals. It is connected to the audio inputs and outputs – no
matter if they are analog, digital or multi channel MADI ports. The audio processing itself is done by several DSPs, which in
turn are controlled by the Control Engine. It consists of several micro controllers, which handle all communication to and
from the control modules and external systems.The Control Engine constantly reads all incoming data on its inputs.
Depending on the configuration, it acts on these events.
As an example, if a fader is moved on a control module, it transmits this event to the Control Engine. This engine reads
the configuration and determines, which audio channel should be affected. After that, a control command is sent to the
corresponding DSP processing unit. The signal gain is changed accordingly.
Of course this is a very simple example, in reality much more complex combinations of control functions and audio
processing are used.
