Neumann's Digital Mic!

Neumann goes digital with the Solution-D, a digital mic offering a host of innovative features. Solution-D offers integrated DSP processing, and its newly-designed A/D converter allows for gain adjustments to be made digitally inside the mic. Smaller productions can be recorded with just the Solution-D and a recording device.

The system of the Solution-D digital microphone generation consists of three components: the Digital Microphone D-01, the Digital Microphone Interface DMI-2, and Remote Control Software RCS that permits operation and thus remote control of the microphone.

You can control standard mic facilities such as the low-cut filter and polar response via a Remote Control Software program with a graphical user interface; the software even shows the signal level of the connected mics. Settings can be saved, and notes (about the mic positions or session setup) may be added. Call us today on this cool new mic!

Includes:
  • (1) DO1 Mic
  • (1) DMI-2 Dig Mic Interface
  • (1) EA2 Shock mount
  • (1) IC3 XLR cable
  • Ships in aluminum carrying case
A new milestone in microphone technology

The Georg Neumann GmbH company, Berlin, has repeatedly played a leading role in the field of analog microphone technology. The first condenser microphone, switchable polar patterns, the first stereo microphone and the 48-V phantom power supply were all developed by Neumann and opened up new possibilities in the realm of microphone technology and recording techniques.

With the Solution-D system, Neumann has now succeeded in developing a digital microphone with the dynamic range and signal fidelity of the best analog studio microphones, thus forging the last link in the chain of digital audio production.

By means of a new, high-quality A/D conversion process, a specially developed synchronization method, and remote control of standard microphone parameters and various integrated signal processing functions, the Solution-D system is able to fulfill the highest demands of professional audio production.

The comprehensive features of Solution-D make it possible to achieve excellent quality even in small productions, using only a microphone and a recording device. Neumann is thus once again playing a pioneering role in the field of microphone technology and recording techniques.

The digital Solution-D system consists of three components: the D-01 digital microphone, the DMI-2 digital microphone interface, and the RCS remote control software which operates and remotely controls the microphone. The signal and data transmission of the microphone conform to the new AES 42-2001 standard that governs the transmission of output signals, the power supply and the remote control of microphones with digital outputs. Neumann was instrumental in drafting this new standard, which provides the necessary preconditions for the development of digital microphone technology.

Any sound engineer who is familiar with digital recording technology can begin production with the Solution-D immediately, without extensive training. The same principles of acoustics and recording technology apply as in the case of analog microphones. However the additional features of digital microphones open up new possibilities during production.

Remote control of standard microphone parameters

With the Solution-D, standard microphone settings such as the polar pattern, pre-attenuation and low-cut filter can be controlled remotely. Changing the settings of microphone parameters is greatly simplified, which facilitates rapid testing of different settings so as to optimize the sound quality. It is no longer necessary to make written records of all the parameters.

Integrated digital audio signal processing

An A/D converter developed by Neumann, especially optimized for capsule signal conditions, receives the output signal directly from the capsule. Gain adjustments required for following devices are performed digitally, in the microphone itself. Analog components such as preamplifiers and A/D converters are thus no longer required, resulting in significant cost savings.

The front-end conversion of the analog signal provides a marked improvement in dynamic range. This is noticeable throughout the entire signal chain, and makes level adjustments less critical.

Mixing console functions such as mute and phase reverse, which affect the microphone signal, are likewise integrated into the microphone. Even commands such as "On Air" (red light) are implemented via remote-controlled LEDs on the microphone. A very special feature is the transient limiter. For the first time, this function can be applied at the most effective point, namely at the signal source, in order to reduce damaging transients that are very short but exhibit a large amplitude. Analog microphones require extremely large headroom in the following signal path to accommodate such signals.

Data transmitted by the microphone

Information transmitted by the microphone includes the name of the manufacturer, the model, the serial number, the software version and a list of all remote-control functions supported by the microphone. Microphone status indicators, including certain warning signals and the ready state, are also transmitted.

The operator can control all the microphones centrally from the control room by means of the Remote Control Software, a graphical user interface which is installed on a desktop or laptop computer.

During production, the sound engineer can continuously monitor all the microphones, since all the important parameters, including signal levels, are displayed on the screen. In addition, a text input field is provided, allowing a channel name to be assigned, e.g. indicating the sound source. All of the microphone settings can be stored in configuration files and retrieved as required.

Why digital signal processing ?

The digitizing of audio data started more than 15 years ago, beginning at the end of the signal processing chain, with the development of the first digital recording devices. By now, digital versions of almost all audio signal processing components are available.

It is well-known that digital signals provide the basis for precise mathematical calculations and processing, permitting signals to be changed, copied, transmitted and stored as desired, with no loss of quality.

In contrast, analog signal processing is characterized by limited precision, error accumulation and a lack of redundant signal information and error correction procedures. Each analog signal processing step is associated with a degradation of the original signal quality. This results in a gradual decrease in the dynamic range, due to the addition of noise voltages and nonlinear distortion.

In addition, digital processing enables functions to be performed which are difficult or impossible to implement with analog signal processing. This applies particularly to functions which require intermediate storage of data.

A/D conversion

Despite continuing improvement, integrated circuits available on the market today still constitute a limiting factor with regard to the A/D conversion of audio data.

For example, the best delta-sigma A/D converters currently available as integrated circuits provide a dynamic range of 115-120dB (A-weighted) for a theoretical word length of 24 bits.

In contrast, a high-quality analog condenser microphone has a dynamic range of up to 130dB. A high-performance A/D converter is therefore required, in order to avoid adding noise to the audio signal. In addition, the conversion process must be optimally adapted to the signal levels and source impedance in the microphone.

In the case of A/D conversion in a mixing console or other device, as a rule, deterioration in signal quality is to be expected, since the conversion occurs only after level matching has been carried out. As a result, the dynamics are influenced by the headroom and by the characteristics of the microphone preamplifier and A/D converter.

Therefore, the goal was to develop a method for performing high-quality digitization of the capsule signal in the microphone itself. This permits level adjustments and other processing steps to be carried out digitally, ensuring that the signal quality generated by the microphone is not impaired by subsequent processing.

Synchronization

The digital audio data stream transmitted by the microphone must be synchronized to allow processing by the mixing console. This necessitated the development of a reliable synchronization method which could function independently of the length of the microphone cable.

The Neumann company has made a decisive contribution in this area, by developing a process that has become part of the AES 42-2001 standard:

At the microphone signal receiver side, a frequency-phase comparison is performed by a master clock, and a rather slow feedback signal is generated to control a voltage-controlled crystal oscillator (VCXO) in the microphone. This sets up a closed feedback loop, similar to a phase-locked loop (PLL). Following equalization and A/D conversion of the feedback signal, it is transmitted to the microphone as part of the remote signal data stream, conforming to the AES 42-2001 standard. This procedure is not only reliable, but also results in very small jitter amplitudes.
