The ADI-2 FS is a compact and extremely flexible 2-channel Hi-End  AD/DA-converter. The small 9.5" unit offers first-class AD/DA-conversion  from/to SPDIF, AES and ADAT, at up to 192 kHz. Its ability to use  SPDIF, AES and ADAT format provides outstanding compatibility. Whatever  it is - simply get connected!


Balanced analog inputs and outputs,  monitoring via headphone output, SteadyClock FS for optimal conversion  quality, 3-stage hardware input and output level control and the  additional modes D-D and A-A turn the ADI-2 FS into a universal tool and  a flexible problem solver. Its pro-class sound qualifies it also as  extension for other premium converters.

The ADI-2 FS is equipped with two servo-balanced analog line inputs  via XLR/phones combo jacks, simultaneously usable balanced XLR and  unbalanced phone jacks, an adjustable High Power headphone output on the  front, an ADAT compatible optical SPDIF I/O, and a coaxial SPDIF I/O  (RCA, AES/EBU compatible). These extensive connectivity options provide  most flexible and uncompromised signal transmission.

The analog inputs use the advanced circuit design of the highly  acclaimed ADI-2 Pro, thus offering outstandingly low noise and  distortion as well as an extended frequency response. Three different  settings for input and output levels provide perfect compatibility in  the analog domain. A further highlight is SteadyClock FS,RMEs  latest clock technology for maximum jitter suppression and lowest  self-jitter. It guarantees superb sound quality completely independent  from the quality of the current reference clock. The ADI-2 FS also uses  the conversion technology of the ADI-2 Pro: the AK557x family and the  AK4490 not only offer 192 kHz sampling frequency and lowest distortion,  but also a dynamic range of 120 dBA.

But the ADI-2 has more to offer than tremendous sound. It also  provides exciting digital connectivity. Its coaxial RCA SPDIF I/O has a  switchable Channel Status to make it fully AES/EBU compatible (cable  adapter required). The optical TOSLINK I/Os can handle up to 192 kHz and  also serve as ADAT I/O, even at 192 kHz. An operation with SPDIF input  and ADAT output or vice versa is supported, in both AD/DA and D-D mode.

The clear layout and distinct labeling of the front panel with its  functional buttons, the informative status display, a 6 LED level meter  as well as the tidy back panel make it easy to operate the unit right  out of the box.

ADI-2 FS Frontpanel

Unexpected Versatility

With input selection set to DIG the device works as a digital format  converter with simultaneous monitoring. The AD converter is disabled,  the DA converter still used for monitoring the digital input signal, at  the rear outputs and the headphone output. A format conversion is  possible between all options - SPDIF coaxial (or AES) with Professional  or Consumer Status, as well as ADAT.

The output selection ANA connects the analog output circuitry  directly to the analog input circuitry. The DA converter is no longer  active. The AD converter continues to convert the analog input signal to  SPDIF (AES) or ADAT, with the outputs SPDIF coaxial and ADAT optical  simultaneously available. This 'analog bypass' allows the ADI-2 FS to be  used as an analog preamp. Gain and attenuation can be achieved via the  level adjustment of input and output, or even fully variable when the  VOL potentiometer is inserted. In this mode, the ADI-2 FS supports  analog levels up to +22 dBu. In addition, it can work as a converter  balanced to unbalanced and vice versa.

The front panel knob adjusts the volume of the headphone output. It  can also be inserted into the rear signal path via a simple key  combination, so that the rear line outputs can be steplessly adjusted in  level as the phones output. The choice of three hardware levels stays  available, thus allows for a better matching of the desired levels on  front and rear outputs.

High Power² Headphone Output

The ADI-2 FS uses a down-scaled version of the ADI-2 Pro's Extreme  Power output stage. With power of up to 0.7 watts per channel, 0.1 ohm  output impedance, a maximum output level of +19 dBu and very low THD  (-110 dB), the High Power² circuitry is universally applicable. A relay  ensures click-free on and off switching.

Power Supply

Power is supplied via an included, external switching power supply  with lockable connector. Thanks to a wide operating voltage range of 9 -  15 volts, the ADI-2 FS can be easily used with battery or rechargeable  battery, thus also for mobile use. It is also fully suitable for e.g. a  galvanic isolation in the laboratory or measuring
