Studio applications and recording with the highest sound standards
In the recording studio and in other recording situations, the highest demands are placed on the quality of the signals. A lot of time is spent to find the right sound, it would be a pity if not every detail is transmitted! When using the XMIC+ board, the recorded signal recreates the full dynamic range of the microphone capsule, thanks to the unique circuit design. Therefore the board meets every quality requirement. The signal from the connected microphones is transmitted unchanged without adding any noise. Unlike conventional recording chains that rely on a microphone preamplifier, the XMIC+ microphone input board converts the signal directly to reproduce the sound true to the source. The XMIC+ board shines, not only in situations where nuances matter, but also in everyday tasks a clear difference to other digital converters is noticeable.
Direct conversion of critical signals with low level
When it comes to digitizing low level signals, the XMIC+ card is the means of choice, as the noise level is lower than that of conventional microphones. By means of an innovative converter concept which, with the aid of several digital converters per input, finds the appropriate level control for the respective level and intelligent DSP technology which measures and corrects the smallest deviations that occur, e.g. by heating the module. With the purely digital amplification, an excellent signal can be provided for further use. This feature is particularly noticeable with low level microphones or even with quiet sound sources, because in a normal procedure, the gain increases the signal before digitization in order to better control the converter, but also the noise of the amplifier. This effectively reduces the dynamics, the upper limit represents the clip boundary. With an amplifierless circuit and gain only in the digital range the entire dynamic range of the microphone is maintained and the noise carpet to be raised is that of the microphone itself.
Applications with a high number of simultaneously open microphones
In situations with a large number of simultaneously open microphones, such as orchestra recordings, a disturbing noise carpet quickly adds up from the basic noise of the microphone preamplifiers and the quantization noise of the digital converters. This phenomenon does not occur when using the XMIC+ card, because in these situations it shines with its very low noise level, which is lower than that of conventional microphones and thus leaves room for even the smallest levels. In addition, the excellent common mode rejection ensures an excellent reduction of interference such as that of lighting systems, which are usually installed in the immediate vicinity of the stage and thus of the microphone sections.
Setups with changing requirements for microphone or line inputs
If you need high-quality analog inputs, but want to connect signal sources with different levels, the XMIC card is the right choice. Although the board still converts the smallest microphone signals with high resolution, it can be controlled with up to 24 dBU, which is significantly above the usual line levels. Using the patented TrueMatch principle, each level is converted with the appropriate amplifier stage, enabling unsurpassed dynamics. This gives the user the freedom to connect line sources to microphone inputs and eliminates the need to think in two categories of input types.
