RME ADI8QS AD/DA Converter
192 kHz 8-channel High-End AES/EBU/ADAT/MADI AD/DA converter

The RME ADI8QS AD/DA Converter is an 8-channel hi-end AD/DA converter with an unrivalled set 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 I64 MADI card) 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 RME ADI8QS AD/DA Converter truly unique.

The unit is 1U in height, and has outstanding AD/DA conversion from/to AES/EBU and ADAT (optional I64 MADI card), at up to 192 kHz. The balanced inputs and outputs use RME's circuit design, guaranteeing outstanding noise and distortion values. Four different input and output levels each are available, offering a perfect adaptation to the analog domain. The latest generation AD/DA converters provide samplerates up to 192 kHz with a SNR of 120 dBA.

Due to its efficient jitter reduction, SteadyClock 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.

RME's superior technology products like SyncCheck ensure perfect synchronization 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 RME ADI8QS AD/DA Converter can be fully remote controlled and configured via MIDI, and all status displays can be queried through MIDI.  Each unit can be given a separate ID, allowing separate remote controllability of various devices with only one MIDI channel.

An included hardware remote allows to control the monitoring volume directly from the working place. A reference volume once saved can be recalled anytime, and of course RME did not forget to add a DIM function (-20 dB). 

The RME ADI8QS AD/DA Converter 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 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!
