RME ADI-8 DS
24-Bit/96kHz, 8-Channel ADAT/TDIF, Word Clock, Bit Split, D-Sub, S/MUX, AD/DA Format Converter

The RME ADI-8 Pro DS is nearly identical to the RME ADI-8 PRO. Additional features include 88.2 and 96 kHz sample rate, Dither and automatic storage of all settings.

DS stands for Double Speed, meaning double sample rate. As ADAT® optical does not support sample rates higher than 48 kHz the DS mode requires two channels to transmit the data of one channel. The used method called Sample Split is compatible to S/MUX, and also found in the Hammerfall and Hammerfall Light. The combination Hammerfall/RME ADI-8 Pro DS allows DVD-compatible Hi-End recordings, at an astonishing low price.

The RME ADI-8 Pro DS is an 8 channel AD/DA converter with reference approach. The compact 19" 1U rackmount enclosure includes several outstanding features, like Intelligent Clock Control (ICC), SyncCheck, SyncAlign®, TDIF/ADAT converter and Bit Splitter. AD- and DA-circuit automatically operate either independently or linked. The latest 24 bit converters with 128 times oversampling achieve 117 dBA true dynamic range. All digital inputs and outputs operate at full 24-bit resolution. If you have been waiting for a flexible, fully professional yet affordable multi-channel converter - the wait is over.

Tour de ADI

The RME ADI-8 Pro DS' astonishing capabilities are easy to explore thanks to a simple and easy to understand user interface. Setting up the RME ADI-8 Pro DS starts with an input sensitivity that perfectly suits your needs and maintains the excellent dynamic range of the AD-Converters. INPUT LEVEL lets you choose between Lo Gain, +4 dBu, -10 dBV.

Each analog input has its own 'Signal Present' and 'Clip' LED, so levels and Overload are easy to check. The key PROCESS activates Bit Split (spread the 24 bit signal on two outputs), Double Speed mode (DS) and Dither (Dith). Bit Split allows two 8-channel 16 bit tape recorders to record 8 channels in 24 bit resolution. Bit Split works with both TDIF and ADAT.

RME's intelligent clock control (ICC) provides professional features you won't find anywhere else. First set the clock of the AD-Converter, choose between INTERNAL, EXTERNAL (BNC word clock) or INPUT (the digital input signal ADAT or TDIF). The internal clock can be 44.1/48 or - when DS is active - 88.2 or 96 kHz. The DA-Converter has the same settings available. The current state of locking and clock synchronization is shown by blinking or constantly lit LEDs. The next key DIGITAL INPUT determines the used digital input, and the clock source in case INPUT was activated.

DIGITAL INPUT is already part of the DA-Converter section. Next is COMBINE, which activates both the re-combination of split signals back to a full 24 bit signal and Double Speed mode. The key COPY MODE routes the digital input to the digital outputs ADAT and TDIF. As these operate simultaneously sending identical data the ADI-8 DS not only turns into a superior ADAT/TDIF converter, but also allows copying between devices of the same format and a distribution to different devices. For example an ADAT signal can be distributed to 2 ADAT plus 2 TDIF outputs simultaneously. In Copy Mode also both Bit Split and COMBINE are available, so it's possible to recombine a split signal while copying, or split a not split signal, or recombine and split again into another format. With this the RME ADI-8 Pro DS turns into an extremely powerful TDIF/ADAT interface.

Each analog output has its own 'Signal Present' LED that works in an analog fashion (brighter at higher levels). A push on OUTPUT LEVEL sets Hi Gain, +4 dBu or -10 dBV as analog output level. RME ADI-8 Pro DS's back shows an impressive number of connectors of all kinds, which result in an unbeaten flexibility and compatibility.

Whatever it is - simply get connected and enjoy the sonic clarity you've been missing when doing multitrack recording for so long.
