RME's ADI-8 QS is an 8-Channel high-end AD/DA converter with an unrivalled set of features. The device combines excellent analogue 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.
Analogue 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 analogue outputs, either separately or globally, digital thru-mode, operation over a wide voltage range and many more features make the QS truly unique.
The ADI-8 QS is RME's reference - highest performance in every detail, at an unbeaten price/performance ratio!
The most important features of the QS:
8-Channel AD converter, fully symmetrical design, 117 dBA
8-Channel DA converter, DC-coupled signal path, double balanced output, 120 dBA
Low latency conversion: only 8 samples of delay!
4 x AES/EBU I/O via D-Sub, 8 channels @ 192 kHz
2 x ADAT I/O, 8 channels @ 96 kHz
Digital input/output trim, range 6 dB per I/O
Analogue 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

Features
This 1U height device offers an outstanding AD/DA conversion from/to AES/EBU and ADAT (MADI optional), at up to 192 kHz. The balanced inputs and outputs use RMEs renowned circuit design, therefore guaranteeing outstanding noise and distortion values. Four different input and output levels each are available, offering a perfect adaptation to the analogue domain. The latest generation of AD/DA converters provide sample rates up to 192 kHz with a SNR of 120 dBA.
Due to its efficient jitter reduction, SteadyClock(TM) guarantees pristine sound quality independently from the quality of the external clock signal. Additionally Intelligent Clock Control (ICC) will retain the last valid sample frequency in case of a loss of the input signal.
The technologies known from other RME products like SyncCheck® ensure perfect synchronisation and clear detection of errors. Multiple units can be stacked and operated sample-aligned, using word clock. All settings are stored when the unit is switched off.
The QS can be
fully remote controlled and configured via MIDI, and all status displays
can be queried through MIDI. Each QS can be given a separate ID,
allowing separate remote controllability of various devices with only
one MIDI channel.
Remote Control
The ADI-8 QS has built-in support for the RME BRC (Basic Remote Control) via the 'Remote' input on the rear panel, although please note that the RME BRC has now been discontinued.
Please also note: the ADI-8 QS is also NOT compatible with the RME ARC USB remote control.
The BRC allows control
of the monitoring volume directly from your work station. A reference volume can be saved for easy recall, and the DIM function allows for a quick reduction in volume (-20 dB).

Low Latency
The ADI-8 QS 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 analogue digital monitoring into real analogue-style monitoring!
Optional: 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.
