ADI-8QS

192 KHZ, 8-CHANNEL HIGH-END AES ADAT MADI AD/DA CONVERTER

RME's ADI-8 QS is an 8-Channel hi-end AD/DA converter with an unrivalled bunch of features. The device combines excellent analog circuit design with outstanding low latency AD/DA converter chips of the latest generation. Along with the integrated SteadyClock, the QS offers an AD- and DA-conversion of the highest quality.

Analog and digital limiters, 4 hardware reference levels up to +24 dBu, AES/EBU and ADAT I/O (optional MADI I/O) at up to 192 kHz, remote control via MIDI, digital input and output trimming for full level calibration, volume control for all 8 analog outputs, either separately or globally, digital thru-mode, operation over a wide voltage range and many more features make the QS truly unique.

The optional i64 module not only adds optical and coaxial MADI I/O, but also enables a digital patch mode between all I/Os, based on blocks of 8 channels.

THE MOST IMPORTANT FEATURES OF THE ADI-8 QS:

8 x Analog I/O (up to +24 dBu)
4 x AES/EBU I/O (8 channels @ 192 kHz)
2 x ADAT I/O (SMUX and SMUX4)
MIDI I/O
Word Clock I/O
optional MADI I/O (I64 MADI Card)
Digital input/output trim, range 6 dB per I/O

Analog and digital limiter for AD-conversion
16 LED level meters with 7 LEDs each
Included Remote control for store/recall, volume and DIM
SyncCheck, unique technology to check clock synchronisation
All settings are stored permanently
Fully remote controllable

Low Latency

In the QS RME uses a high-class AD converter from Cirrus Logic, offering exceptional Signal to Noise and distortion figures. But the biggest difference to all other ADCs out there is its innovative digital filter, achieving for the first time a delay of only 12 samples in Single Speed (0.25 ms), 9 samples in Double Speed (0.09 ms), and 5 (!) samples in Quad Speed (0.026 ms).

These values are less than a quarter of those available from even much more expensive devices. They represent an important step in further reducing the latency in the computer-based recording studio. At DS and QS the added latency can simply be ignored. The DA-converter offers similar conversion in the range of 5 to 10 samples, turning analog digital monitoring into real analog-style monitoring!

OPTIONAL: I64 MADI CARD

The I64 MADI Card extends the QS with a 64-Channel MADI input and output and a sophisticated digital patch mode.

The card has an optical and a coaxial MADI input, which is switched automatically according to where a valid input signal is detected. This ensures full redundancy by immediately changing to the other input in case of signal loss. Coaxial and optical output operate in parallel, delivering the same data.

The QS can also be remote controlled via MADI, and send/receive MIDI data via MADI.

Additionally the i64 card enables a digital patch mode, that allows free routing of all I/Os based on blocks of 8 channels (needs i64 MADI card with Sync LEDs and firmware 3.x or up). Please read the QS manual for more detailed information
