RME ADI-8 QS MADI
RME ADI-8 QS MADI -
The ADI-8 QS is a new highly flexible and fully featured 8-channel AD/DA converter. The ADI-8 QS combines excellent analog circuit design with outstanding low latency AD/DA converter chips.
Reference class 8-channel, 24 bit/192 kHz remote controllable AD/DA converter
New digital filters reduce the conversion delay to just 8 samples
2 x ADAT I/O, 25-pin AES/EBU, expansion slot for MADI option card
Full remote control, intelligent Clock, SyncCheck, and SyncAlign
Along with SteadyClock, the QS surely redefines the reference class of analog/digital converters. The compact 19"/ 1U device has a host of extraordinary features, including analog and digital limiters, 4 hardware reference levels up to +24 dBu, AES/EBU and ADAT I/O up to 192 kHz, optional MADI I/O, remote control via MIDI, remote digital input trimming for full input calibration, remote volume control for all 8 analog outputs, either separately, globally, ganged and much more.
The analog inputs and outputs feature the same circuitry as RME's well-known ADI-8 series, ensuring excellent signal to noise ratio and low THD. On the digital side, SteadyClock, RME's unique clock technology and jitter suppression, further enhances the list of features, ensuring the best sound quality regardless of the quality of the reference clock signal. The QS uses the latest AD- and DA-converter circuits with up to 192 kHz, with S/N ratios of 120 dBA. New digital filters reduce the conversion delay from over 40 samples to just 8 samples. Now that's some serious low-latency!
Numerous Interface Options
The ADI-8 QS also offers an unsurpassed choice of interface options. In addition to 2 ADAT I/Os that support up to 192kHz (S/MUX), the device also features a 25-pin AES/EBU interface for all inputs and outputs. And that's not all - The ADI-8 QS features RME's latest technological achievement - an expansion slot that makes the device even more flexible. The slot can host a MADI option card for direct connection to MADI systems. All interface options can be used simultaneously under all conditions; analog (balanced TRS and/or D-Sub), ADAT, AES/EBU and the MADI option card.
Within the ADI-8 series of converters, the full remote controllability of the QS allows the device to be placed anywhere on stage or in the studio as a remote controllable SuperStageBox with full access from the control room or FOH mixer. Other typical RME features like Intelligent Clock Control (ICC), SyncCheck, and SyncAlign have also been implemented.

I64 MADI Card:
I64 MADI Card
The I64 MADI Card provides the QS with a 64-Channel MADI input and output. Coaxial and optical output operate in parallel to the AES/EBU and ADAT output, therefore deliver the same data.
The I64 MADI Card features an optical as well as a coaxial MADI input. The input is switched automatically, according to where a valid input signal is detected. Full redundancy is ensured by the automatic input switching, immediately changing to the other input in case of loss of the input signal.
The MADI input will operate as an optional clock source (Clock section, OPTN), as signal source of the DA-converter and as thru-input. Since each QS uses only 8 channels, up to 56 channels can be passed through. This technique is used to serially cascade several QS converters. Incoming MADI data is passed through unchanged, only one block of eight channels is replaced. This allows up to 8 devices to be connected serially. All 64 combined channels are available at the last device's MADI output.
With an installed I64 MADI Card the QS can also be remote controlled via MADI. At the same time MIDI data are transmitted via MADI.
When multiple devices are connected serially, the MADI I/O of each QS causes a delay of 3 samples. Therefore at the MADI output of the last device, the data of all upstreamed devices are delayed. The problem of this offset is solved by the function Delay Compensation.
