ADI-8 DS

High-Precision 8-channel 96 kHz ADAT . TDIF AD/DA converter

Overview

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  exible, fully professional yet a ordable multi-channel

converter - the wait is over!

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.

Use the following feature list to compare our ADI-8 DS with all other multitrack converters, and you will agree: The

ADI-8 DS has the best price/performance ratio!

- 8 channel AD-converter, completely symmetrical and DC-coupled audio path, 117 dBA SNR AD

- 8 channel DA-converter, balanced output, 112 dBA DA

- ADAT optical inputs, 24-Bit, based on RME’s unsurpassed Bitclock PLL for sample accurate lock

- ADAT optical outputs, 24-Bit, fully compatible to all ADAT optical inputs

- TDIF-1 interface, 24-Bit, Low Jitter PLL, Emphasis support, DA-88 compatible

- Bit Split/Combine, Copy Mode, ADAT and TDIF usable in all combinations

- Copy Mode adds a unique 24-Bit ADAT to/from TDIF converter

- Digital Patchbay operation, allows to copy, duplicate and distribute the digital input signals

- Dither available, for full compatibility to 16-Bit even at 96 kHz

- SyncCheck, unique technology to check clock synchronisation

- Virtual Sample Bu er, allows to use the internal Low Jitter Clock (quarz crystal) even for DA-conversion

- Automatic storage of all settings

Features The ADI-8 DS’ astonishing capabilities are easy to explore thanks to a simple and easy to understand user interface. Let’s have a short walk over the front panel from left to right. Setting up the ADI-8 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.

Analog to Digital Physical access to the analogue inputs is either via 1/4” stereo jack socket or 25-pin D-type connector conforming to the Tascam DAxx analogue I/O pinout. These recorders are very common, so a suitable multicore cable (e.g. for connecting directly to mixing consoles or to XLR) should be relatively easy to find. The entire input stage - from the sockets to the converter chip’s internal input - is fully symmetrical.
