5Key Features
The 52/RX Mixing Console, with its 4 to 48 faders, resembles the layout of its predecessing models RM4200D and
RM3200D. At the same time, it features prominent advantages of the Series 52, e.g. linking via Ethernet, operation of up
to 4 independent mixers with one DSP Frame, and the freely configurable TFT Views. Due to module sizes similar to the
mentioned systems, existing RM4200D systems can easily be extended to be a Series 52 mixer by replacing the control
modules and upgrading to the Toolbox5 software and the RM420-852/853 Communication Controller, while keeping DSP
Frame, I/O modules, table installation frames and studio furniture unchanged.
The Series 52 Mixing Console 52/RX has been designed to be an easy-to-use tool for a broad range of TV and radio
broadcasting applications.
It can also be used for:
•On-Air and continuity studios
• Pre or post production, recording, editing, dubbing
•OB Vans and other field applications
The 52/RX uses a special real-time operation system running in the DSP frame. There is no PC-based system inside and it
works completely without any PC.
The configuration software runs on standard Windows(TM) based PCs. However, this PC is not needed to run the 52/RX
from day to day – it is only needed for setting it up.
ASeries 52 Mixing Console 52/RX remotely controls the processing power of a DSP core via TCP/IP. The combination of
the proved and reliable DSP power of an RM4200D DSP Frame together with the Series 52 RM420-852/853
Communication Controller provides you with a great variety of features.
With the completely redeveloped Toolbox5 configuration software, you can flexibly adjust the available audio and logic
resources of your mixing system to meet your individual requirements. Providing a complex range of configuration options,
the software still stays intuitive and easy to use.
6Applications
Note
You need an RM4200D DSP Frame equipped with the RM420-852/853
Communication Controller to operate an 52/RX Mixing Console.
The mixing system consists of two main parts, which are coupled via an industry standard Ethernet connection. These
parts are:
·The DSP Frame. This unit includes all input and output modules, the DSP Audio Engine and the Control Engine.

·The Mixing Console. This is the user interface of the mixer with all faders, control knobs, push buttons, displays and
TFT screens.
Note
To power the modules of the mixing console, you need the necessary number of
PoE-Switches (Power over Ethernet) and a 48V power supply. The PoE switch
must be a DHD type.

DSP frame and control desk coupled via Ethernet.
The mixing console has a modular design, which allows to combine different modules for different applications. All fader
and control modules and TFT displays are linked to PoE switches and finally to the DSP frame via CAT5/6 cables. Modules
can be located apart from each other, as long as the specifications for cable length and power supply are met. The cable
lengths between the control panels and the DSP Frame can be up to 100 m with CAT6-cables. Even larger distances can
be realized with a conversion to fibre-optic cables.
There are two basic kinds of control modules – those containing faders and those without faders. Up to 12 fader modules
(48 faders) can be used together in one single mixing console.
Because the parts of the system are coupled by CAT5/6 cables, you can install them in your furniture at will instead of
having the furniture built around a more traditional mixing desk. The installation depth for the desk-mounted modules is
only 56 mm.
The mechanical construction of all modules is designed to withstand 24/7 use. Sturdy components like EAO Lumitas and
NKK keys, Penny & Giles faders and Lexan foil covers on all front panels let the 52/RX perform for a long time.

7 Examples
The following examples illustrate some typical applications of the 52/RX Mixing Console. Of course, more combinations of
modules and functions are possible. If you need help to define your requirements for an 52/RX, please contact your local
DHD partner.
This examples should show the following possibilities:
·external PoE switches (example 1)
·PoE switches inside a power supply frame (example 2)
You can find general information on Ethernet wiring in the first example, which is also valid for all other examples.
7.1 Example 1: Self Operating Desk
The following example shows a possible combination of modules for a self operating desk and it should explain the
Ethernet wiring of this application. Please use CAT5 cables continuous for wiring. But DHD recommends to use CAT6
cables for longer distances.
Connect the bottom RJ45 jack of the RM420-852/853 Communication Controller of your RM4200D DSP Frame to the
configuration PC or to the DHD Ethernet network, where the PC with the configuration software is located. To establish
the connection to the office network, you should use a server PC with a second network interface card to avoid slowing the
communication in the DHD network and to block non-authorised access to the connected DHD systems.
The middle connector of the three RJ45 jacks needs to be connected to a switch of the DHD network. Because the
controllers and the control modules are power supplied by the Ethernet connection (Power over Ethernet), you have to
integrate at least one power over Ethernet switch (PoE switch) into the controller network. The total number of needed
PoE switches depends on the number of connected control modules (each module is equipped with a 52-4050 controller)
and TFT displays. Use only switches in the DHD network and the controller network, which are shipped and/or
recommended by DHD for the usage in these networks. Especially the switches must be Unmanaged Switches working
with a speed of 100 Mbit/s.
The following non-PoE switches are tested by DHD and are recommended for the usage in DHD Ethernet networks and
controller networks:

7.2 Example 2: Network with two 52/RX Consoles
The following example shows a possible combination of modules for a network with two 52/RX consoles and it should
explain the Ethernet wiring of this application. Please use CAT5 cables continuous for wiring. But DHD recommends to use
CAT6 cables for longer distances.
In general the assembly is similar to the application in example 1. But in this example two independent mixing systems,
each consisting of an RM4200D DSP Frame and an associated 52/RX console, are working in the same DHD Ethernet
network. Both systems are configured by the same PC in this example.
You can insert 52-5088 PoE switches into the Power Supply Frame 52-5083, like it is shown on the right-hand side of this
example.

8Principle of Operation
The 52/RX is based on a simple philosophy: The hardware modules provide a stable and powerful foundation for a special
software, which in turn implements all the available functions of the system. At first this concept might be difficult to
grasp, but once you understand it, a lot of things will become clear.
Basically you connect a number of modules together and afterwards a software is used to configure the way the system
works. This approach is the key element to the versatility of the system, because the configuration is by no means final. It
can be changed anytime, by anyone who knows how to do it. That way, the system can be adapted to changing
requirements during its whole life cycle. If you are refurbishing your studio and need to change its configuration – just do
it. If you are buying more modules to extend your system, the software will easily integrate this new hardware. Of course
you will always need a DSP frame and certain modules for signal input and output as well as for controlling the system.
But how these modules work together can be changed anytime by software.
The 52/RX Mixing Console itself is controlled by the RM4200D DSP Frame and has no own intelligence.
When the hardware of an RM4200D DSP Frame is assembled at the factory, it is „blank“. A configuration file needs to be
uploaded to the system to let it perform its tasks. What a such configuration looks like and what it does is determined by
the requirements of the prospective users of a certain system. DHD and its partners assist in designing a matching
configuration for the customers application. If desired, an RM4200D DSP Frame can be delivered without any configuration
and the customer can use the included configuration software to adapt it to his requirements himself.
Note
Please see the RM4200D manual to get more information on the RM4200D DSP
Frame.
The configuration of the 52/RX Mixing Console and the RM4200D DSP Frame is
described in the Toolbox5 configuration software manual.
Please keep in mind, that configuring an RM4200D DSP Frame and its connected 52/RX Mixing Console is a step-by-step
process. A configuration is designed using the configuration software and is than uploaded to the system. After that, the
system stays in the currently configured state until the upload process is repeated. The configuration software and the PC
it is running on are not needed during normal operation of the system. This implies that the configuration can not be
changed „on the fly“ during normal operation of the system.
Another consequence of the configuration process is the fact, that the system only does what it is told to do by the current
configuration. If the system shall perform a certain function, it must be configured to do so. During the configuration
process there are already many high-level functions available to choose from. Additionally, more complex functions can be
build with the configuration software for special applications.
Since there are so many configuration options available to choose from, it pays off to invest some time into thinking about
the requirements of the desired application. If these requirements are clear, it is a good idea to discuss them with your
DHD partner. He will help you to find the matching solution for your application.
If you are planning to purchase an Series 52 mixing system for the first time, you might be uncertain about the right
configuration for your requirements. As a start, think about the following things:
·The number and kind (analog, microphone, digital, MADI) of the desired inputs and outputs.
·The number and kind of faders and control modules you need.
·The special functions you require for monitoring, talk-back, routing and On Air switching.
·The number of buses and clean feeds.
·How are you planning to install the modules mechanically?
Furthermore, for the configuration of the DSP frame you need to know:
·The functions you need for signalling and integration with other systems.
·Will you need more than one mixing system? If yes, how will they be networked with each other?
With the help of this list DHD and its partners will be able to select the right hardware modules and the matching software
configuration for your application. In case your requirements should change later on, the system can easily be adapted –

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.

Detailed information on the Audio Engine and the Control Engine of the
RM4200D DSP Frame as well as the connection of external elements can be
found in the RM4200D manual.

Control Modules (52/RX)
The control modules are the interface between the user and the functions of the mixing system. Different control modules
are available, each of them providing its own set of features. Moreover, you can integrate TFT screens into your setup.
These TFT displays are not only able to show information. Due to they are sensitive to touch, you can design views with
buttons to control functions via the TFT screens.
Weblink
For a comprehensive list of all available modules, please see the 52/RX List of
Modules.
All control modules have in common that they consist of control elements – such as faders, buttons, rotary knobs – and
status indicators. These are LEDs inside the buttons, alphanumeric displays for text, defined parts of TFT views and so on.
Some typical applications for displaying information to the user are:
·LEDs showing the active bus assignment for a given channel.
·An alphanumeric display in the fader modules shows, which input signal is selected for a given channel and shows a
channel timer.
·Alphanumeric displays on the main modules give several feedback to the user and offer menus for different selections.
·LEDs inside the push buttons are switched on or off to indicate the state of the button.
All control modules are tightly integrated with the Control Engine. It collects all events from the faders, rotary knobs and
buttons and sends back the information into the status indicators and displays. Using the configuration software, the
functions of all control elements and status displays can be defined according to the given application of the mixing
system. As with the Audio Engine, this configuration can be changed anytime, if desired.
To make configuration easier, the software allows to print out labels for the buttons of the control modules. These labels
are slid under the key caps. If necessary, they can be changed again later to reflect changes in the configuration of the
system.

9Further Information
9.1 Suitable PoE Switches for DHD Devices
The available PoE switches of the computer distribution business are often not suitable for the use with DHD devices,
because there are different sub versions of the PoE standard "IEEE 802.3af". Hence, not all devices are able to work
together. Indeed, it is only possible to test the interaction, but DHD strongly advices against doing that. Only the DHD
components 52-5088 and 52-4080 are recommended.
Disadvantages of non-DHD PoE switches:
·The interaction with DHD components can not be guaranteed by DHD. Hence, in case of fault, DHD declines any
warranty and support for such systems.
·Mostly, devices without cooling fans are not available. The usage of devices with cooling fans within studios and other
recording rooms is only restricted possible.
·The needed power of the DHD components from 10W to 15W per port that is connected with a PoE end device, is often
not provided for a larger number of ports. That especially applies to low cost devices.
·At this time, there are only a few devices with redundant power supply available.
·More significant devices are often managed switches, that are not recommended in general according to the DHD
network specifications.
·With some of the by DHD tested devices (power source), problems occur after switching-on. In some cases this
procedure had to be repeated to recognize the standard compliant DHD end devices and to switch on the 48V supply
voltage.
