3. Brief Description and Characteristics

The ADI-96 PRO is a 2-channel analog to digital converter in a 19" rackmount enclosure
of 1 U height. Newest 24 bit converters using 64 times oversampling result in 115 dBA dynamic
ratio. This value is not only printed in the brochure, thanks to our Low Jitter Design it is avail-
able with every sold unit.
The servo balanced line inputs are fitted with both XLR and 1/4" TRS jacks separately. The
signal path from the jacks to the ADC is totally balanced. A super low noise amplifier stage
provides 20 dB adjustable gain, set by two hi-precision potentiometers on the front panel. This
brings a perfect adaptation to the most used levels -10 dBV and +4 dBu for each channel sepa-
rately.
The discrete low noise and low distortion microphone preamp works totally independent from
the line circuits. A high quality relais connects the output of the line and mic electronics directly
to the AD-converter. The Mic XLR jacks also provide +48 V of phantom power for condenser
microphones.
The clearly structured front panel design ensures an easy start when working with the device
for the first time. The Peak Level Meter is visualized by a hi-precision LED chain with reliable
Over detection. The AD-converter is able to sample at 32, 44.1, 48, 64, 88.2 and 96 kHz. The
digital output is available at SPDIF (coaxial and optical) and AES/EBU (XLR) connectors.
Thanks to the unique Constant Double Speed technology the crystal clear sound of 96 kHz
sample rate is preserved even when using common sample rates below 64 kHz, as the ADI-
96 PRO samples and calculates in double speed. RME's exclusive Analog Processing
brings typical analog behaviour and sound to the digital domain. When using Look Ahead our
Digital Processing technology minimizes changes in sound even with heavy processing.
The DSP adds phase shift, low cut and mid/side processing in pure digital 48 bit quality. Proc-
essing all data in the DSP avoids all unwanted effects typical for analog circuitry, like additional
noise, distortions, changes in frequency response and deviations between both channels. Cal-
culating Phase, Low Cut, Expander, De-esser, M/S-Processing and Compressor by a 48 bit/96
kHz DSP results in a previously unreached sound quality.
