Page 3: Introduction
3. Brief Description and Characteristics The ADI-2 is a 2-channel analog to digital and digital to analog converter in a half-rack (9.5") enclosure of 1 U height. Latest 24 bit / 192 kHz converters offer up to 119 dBA dynamic ratio. -

Output voltage RCA Consumer 0.8 V, Professional 2.3 V 5. Power Supply In order to make operating the ADI-2 as flexible as possible, the unit contains a switching regulator of the latest technology, which not only has a high efficiency (> 90%), but also prevents internal hum noise by operating beyond 100 kHz. -
Page 6: First Usage - Quick Start
–3 LEDs light up. The analog line inputs of the ADI-2 can be used with +4 dBu and -10 dBV signals. The elec- tronic input stage is built in a servo balanced design which handles monaural and stereo jacks correctly. -
Page 7: Inputs And Outputs
The amount of headroom is different in different standards and again differently implemented by different manufacturers. Because of this we decided to define the levels of the ADI-2 in a most compatible way. The headroom of the ADI-2 is defined according to the chosen reference level. -
Page 8: Analog Outputs
When used unbalanced it automatically corrects the gain by 6 dB. To maintain an optimum level for devices connected to the analog outputs, the ADI-2 includes a discrete hardware gain stage, directly behind the DA-converter. Electronic switches of the latest technology, which introduce no additional noise or distortion to the audio path, are used to control the gain, and offer highest operating comfort. -
Page 9: Digital Inputs
The digital input format is detected automatically. Be it AES, SPDIF or ADAT, further settings at the ADI-2 are not necessary. In case of ADAT optical only channels 1 and 2 are converted to analog, channels 3 to 8 are ignored. -
Page 10: Digital Outputs
7.4 Digital Outputs The ADI-2 has a coaxial and an optical digital output. The key OUTPUT sets the format: ADAT: The optical TOSLINK output operates in ADAT mode. Included support for Sample Split (S/MUX) enables sample rates up to 96 kHz. -
Page 11: Clock Section
The ADI-2 has to be master, all attached devices slave. To prevent clicks caused by imperfect or even no synchronisation, a special method called SyncCheck compares the synchronisity of the incoming data with the internal clock of the ADI-2. The actual state is indicated by a blink- ing (error) or constantly lit (Ok) CLOCK LED. -
Page 12: Noise Level In Ds / Qs Mode
9. Noise level in DS / QS Mode The outstanding signal to noise ratio of the ADI-2 can be verified even without expensive test equipment, by using our famous DIGICheck tool or the record level meter of Steinberg's WaveLab. When activating the DS and QS mode, the displayed noise level will rise from -110 dB to -104 dB at 96 kHz, and –82 dB at 192 kHz. -

Page 16: Warranty
RME does not accept claims for damages of any kind, especially consequential damage. Liabil- ity is limited to the value of the ADI-2. The general terms of business drawn up by Synthax Audio AG apply at all times. - Page 17 In order for an installation of this product to maintain compliance with the limits for a Class B device, shielded cables must be used for the connection of any devices external to this prod- uct.
