1. Introduction

The Digital Audio Mixer RM3200D is especially designed for applications in broadcasting. It can equally be used for:

• Broadcast and pre-production for self operation studios or control rooms with one or more studios

• Routing applications

• Audio workstations for editors

• Stations for sound editing and recording

• Video-postsynchronisation and cutting

Up to date workstations in the broadcasting business are often used by people who have small or no technical background. Therefore, the control desk of RM3200D has been especially designed for ease of use and accessability.

For the use in On-Air studios, the mixer can be integrated with automation systems. Optional motor faders can also be used.

RM3200D is the ideal mixer for computer aided systems for sound editing and recording. All necessary functions for these applications are integrated into the system without having

to be specified by the user:

• N-1-summation (mix minus) with preparation mode

• Monitoring including monitor-mute at open microphone

• Independently adjustable monitor and headphone outputs

• In and Out of talkback sign als

• Red-light signalling or fader start contacts and many other logic functions.

Further special functions for monitoring and logic that are typical for broadcasting can be configured.

Microphone processors can be replaced by the DSP functions of the RM3200D: equalizers, dynamic unit (compressor, expander, noise gate) and deesser are integrated. User specific configurations can be stored in Flash-EPROMS. The assignment of the faders to the input channels is stored as well.

RM3200D is the first digital audio mixer of this class where the internal signal processing is carried out with 32bit Floating Point DSPs (Analog Devices SHARCs). Internal overmodulations as sometimes occurring in devices with fixed point processors should not occur here, since the dynamics range is greater than 1000 dB(!).

Asynchronous sample rate converters are used in the digital inputs of the RM3200D. Thus, digital consumer devices and non-synchronisable professional devices can be digitally connected to the mixer.

Despite its wealth of features and its flexibility in adapting to different applications, the costs for the mixer are competitive compared to an all-analog setup.

2.1 Principle of Operation

2. RM3200D System Design

2.1 Principle of Operation

The RM3200D Mixing and Routing System is built with 2 main hardware parts, the:

1. DSP Frame with all Inputs, Outputs, the Control System and DSP

Power

2. Control Desk with all Faders, Push Buttons and Displays

Both are coupled via an industry standard CAN-bus connection. Thus, the units can be placed separately from each other without big wiring efforts.

The DSP Frame can also be used as single device without the control desk, for example as a routing system. In this case, the device is controlled over a controlling protocol.

With our DHD Control Protocol you can access any available internal function via CAN Bus or commonly via RS232/RS422.

Also, we have some PC based windows software tools:

• Configuration Software, for the configuration of the system and for maintenance

functions

• Routing Software (RM330-050) which also includes a small scheduler and macro functions

1.) Digital Signal Processing

Chapter 2: RM3200D System Design

2.1 Principle of Oper ation

2 - 7

• DSP Function Control Software (RM330-051) for easy controlling of the audio processes in a channel

• Mixer Control Software (RM330-0553)

You do not need the PC software tools for the “normal work” – the RM3200D has no PCs inside and works completely with out any PC.

For both main hardware parts we have several different modules that will be described in the next sections.

The DSP Frame of RM3200D can provide a total of 264 input channels: up to 96 mono channels over A/D-converters or digital input modules, plus 3 multi channel inputs (MADI or proprietary formats with up to 56 channels for each module). It can output up to 96 mono channels over D/A-converters or digital outputs and 3 multi channel outputs (56 channels each).

Due to the compact size of the control desk, the RM3200D can be functionally integrated into a workplace. The desk consists of a main module and fader modules. The main module contains 2 monitor level controllers, 49 keys, an ASCII display and a rotary knob for adjusting settings. The fader module is equipped with 4 faders, 20 keys and 4 ASCII displays.

A maximum number of 20 faders per mixer is possible (5 fader modules). The fader modules and the main module are closed modules with their own microcontroller

logic, thus offering the opportunity to be built in separately. They are interconnected only via one cable using 4-pin XLR-connectors (+24 V, CAN+, CAN-, GND).

The DSP Frame contains all signal processing, consisting of the following:

• DSPs

• A/D- and D/A-converters and microphone amplifiers

• Digital in- and outputs

Chapter 2: RM3200D System Design

2.1 Principle of Operation

• Multi channel in- and outputs

• Controlling in- and outputs

• Clock generation

• Power supplies

The standard size of the DSP Frame is 19''/6U, for smaller systems 3U height. Both control desk and DSP Frame use identical controller systems based on the industry-

standard 68k microcontroller. The whole system is to a large degree built in a modular way. It is configured by the PC

software supplied with the system. The software runs on a standard Windows system (Windows NT , Windows 95/98). This PC is not necessary for daily operation, since all setup information is stored in the system itself.

The power for the control desk is supplied from the DSP Frame or a separate power supply unit with a voltage of 24V.

The RM3200D is ready for operation within 1 second after switching on or restarting. The mixer can be synchronized using an internal (48 kHz, 44.1 kHz) or an external clock. A

TTL-wordclock, the clock of a digital input or the clock from the MADI input can be used as external clock. On failure of the external clock (Sync Source 1), the device automatically switches to the internal quartz or another external clock (Sync Source 2).

Important parameters like the function of the CAN-bus, all distribution voltages, sampling clocks or the temperature within the device are constantly monitored in the background. If they exceed the limits given by the manufacturer, an alarm is triggered (LEDs in control desk and DSP Frame, triggering of a relay, logging of alarms on a PC is possible). The light bulbs in the control desk are monitored as well. If one of them fails, an alarm is triggered.

The power consumption of the device is small compared to commonly used devices. Depending on the level of extension, the power consumption is approximately between 30W and 120W.

Except for the mechanical wear of the input devices (faders, keys), the front panels and the lamps (bulbs, LEDs), the mixer is maintenancet free. No batteries or hard disks are used.

2.2 Functions

2 - 9

2.2 Functions

RM3200D can be equipped with a maximum of:

• 264 input channels (mono) and 264 output channels (mono)

• 42 summing buss es (f or p rog ram bus ses, aux buss es, mix- mi nus- buss es/c onf ere nce

matrix, PFL bus)

• 6 independent monitoring paths (stereo), each can be configured as output for monitor, headphones or level metering

All inputs and Aux sends can be used as 1 or 2 channels (stereo). In stereo, all functions of the two stereo channels (filter configurations, level values, etc.) are coupled with each other.

If necessary, the input channel for a fader can be selected using an input crossbar. With the Input Select function, all existing inputs can be accessed even with few faders. The selected input channel is displayed in the fader display. Logic Functio ns like fad er s t art ar e linked to the actual channels (not to the faders), also the parameters for the DSP functions (gain, EQs...) in the channel.

The following functions are available on the input fader channel:

• Input routing with the DHD Pool Fader Function

• Summation and Aux selection

• Linking to monitor busses 1...6

• Several logic functions like fader start (static or impulse), monitor mute, timer start,

telephone hybrid on/off, voice/music signalisation etc. (ref. section Logic Functions)

• Equalizer, various EQs can be cascaded

• Limiter, compressor, expander, noise gate

• Deesser

• The sequence of the DSP functions can be configured as required. The overall

computing power of the system determines the maximum number of DSP functions available.

It is possible to use DSP functions like limiters, compressors or EQs after summing busses with the internal fixed processing functions.

To build special functions like split headphone or talkback, we have up to 54 powerful output functions.

Also the system has a full function output routing without any restriction. Additionally, a lot of powerful logic functions and special functions like level detectors

available. Logic functions (global functions) and fadervalues (global pots) are interchangeable via RS232/422 to other RM3200Ds.

Important Note: The RM3200D is not a system with dedicated functions. With the

powerful configuration software DEFINITION.EXE and the several available hardware modules, the system can be entirely configured by the user.
