The ADI-96 PRO is RME's most outstanding project: a professional 24 bit/96 kHz stereo AD-converter with servo balanced line and microphone inputs. The technical data are of the best you can get today. Modern 24 bit ADCs with up to 96 kHz sample frequency and real 117 dBA dynamic range, a variable frequency synthesizer PLL in double speed technology (Low Jitter Design), CDS® (Constant Double Speed) for highest sound quality even when sampling lower than 64 kHz, Analog Processing or clipless Digital Processing with Look Ahead, and a hi-speed DSP calculating in 48 bit/96 kHz make up a powerful, easy to use device.

DSP FUNCTIONS OF DUAL MONO A/D  
   * CDS®
     CDS (Constant Double Speed) maintains the crystal clear sound of 96 kHz sample rate even when using usual (lower) sample rates. In CDS mode the ADI-96 samples and calculates the audio data with double speed. Before the data reach the digital output they are downsampled to compatible values.
      
   * De-esser
     A De-esser reduces the level of high disturbing sounds (sibilants) in vocal recordings. The ADI-96 uses a configurable dynamic notch filter, but needs no adjustment when the level changes. A special adaptation function compares the overall level with the level of the filtered signal, and changes the Threshold so that a relative level operation is realized. Adjustable from 0,7 kHz to 20 kHz, Q from 0.2 to 10, Ratio 0 dB to -50 dB.
      
   * Expander
     An Expander lowers the signal 'smooth' according to a given characteristic (Ratio) when the level drops under a given level (Threshold.) With this music can be faded in and out without audible distortion, noise between tracks can be easily suppressed. With a more extreme setting, like Ratio 5:1 and Release 0,1 s the Expander operates like a Noise Gate. This for example allows to isolate percussive instruments from environmental noise. With activated Delay the Expander operates in Look Ahead mode. Adjustable from -30 dBFS to -110 dBFS, Ratio 1,2 to 5,0, Attack Fast (1 ms) or Slow (25 ms) and Release 0,1 to 25,5 seconds.
      
   * Low Cut
     High pass filter 12 dB/oct with a resolution of 48 bit, adjustable cutoff frequency from 2 Hz up to 250 Hz. Removes unwanted rumble and low frequency noise when recording from microphones, or transferring old analog audio material. At a setting of 2 Hz also useable as DC-filter.
      
   * Non Linear Compressor
     Realizes a non linear compressor or 'soft limiter' function. Consists of a brickwall limiter with optimized harmonic rendering. Even at +5 dB it is nearly impossible to hear any distortion in mixdowns. Very good for maximizing loudness or when needing additional headroom. Similar to the effect known as tape saturation.
      
   * Auto Level Control
     Serves as automatic level control. When the input signal does not reach a given level for a given time the gain is raised. Optimizes the average recording level, avoids recording levels that are too low. At lower Rise time settings the ALC operates as digital Compressor. In conjunction with the NLC an effect widely known as 'Maximizer', causing an enormous raise of the volume/loudness at minimal audible artifacts can be achieved. With activated Delay the ALC operates in Look Ahead mode. Adjustable are Gain 0 to 24 dB, Headroom 1 to 12 dB and Rise 0,1 s to 25,5 s.
      
   * Delay
     Independent delay for left and right channel up to 170 ms in steps of 0,1 ms. Can be used to eliminate acoustical delays from critical microphone positioning or in bigger acoustical environments (PA.) May be used to generate a light stereo effect by delaying only one channel. Activates the Look Ahead mode for Expander and Auto Level Control.
      
   * Phase
     Phase correction 180° for left, right or both channels. Removes problems with stereo to mono conversion.
      
   * Bit Resolution and Dither
     ADI-96 PRO always samples in 24 bit resolution. The output can be configured to 8, 16, 20 or 24 bit word length. As this would lead to audible distortion at 8 and 16 bit at lower levels, it is possible to add Dither (0,5/1 LSB) to the output signal. Then the signal will be rounded to the desired resolution.
      
   * M/S Processing
     The mid/side processor transforms recordings done in the mid/side positioning technique to a usual left/right stereo signal. Additional it processes usual stereo signals into a mid/side signal. This allows to check a completed mix on the included stereo information, or to manipulate only the stereo signals.
