RME ADI-8 DS 8 Channel AD/DA Converter

Full Description

The ADI-8 DS is nearly identical to the ADI-8 PRO. Additional features include 88.2 and 96 kHz sample rate and Dither.

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/ADI-8 DS allows DVD-compatible Hi-End recordings (up to 8 channel @ 96 kHz), at an astonishing low price.

The ADI-8 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.
