Hi-Precision 8-Channel ADAT®/TDIF
AD/DA Converter |
|
|
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.
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, Yamaha
02R compatible technique to record 24 bit data onto 16 bit machines
- Copy Mode adds a unique 24
bit ADAT to/from TDIF converter
- Bit Split/Combine, Copy Mode,
ADAT and TDIF usable in all combinations
- 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 Buffer, allows
to use the internal Low Jitter Clock (quarz crystal) even for DA-conversion
- Automatic storage of all settings

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. 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 ADI-8 DS turns into an extremely
powerful TDIF/ADAT interface.
Each analog output has its own 'Signal Present' LED which 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.
ADI-8 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.
