The ADI-8 QS M from RME is their top of the line, eight-channel analog-to-digital and digital-to-analog converter that balances excellent analog circuit design with the latest in converter technology. The combination provides conversion of the highest order along with a healthy supply of features.

The unit is outfitted with both balanced 1/4" phone input/output connectors, along with 25-pin D-sub connectors, the latter providing slightly higher maximum output levels. Conversion is available to/from AES/EBU and ADAT optical at sample rates up to 192kHz for the AES/EBU streams and 96kHz for ADAT. The installed I64 MADI interface card provides the ADI-8 QS M with sixty-four channels of MADI input and output.

Efficient jitter reduction via SteadyClock guarantees prestine sound quality while Intelligent Clock Control (ICC) will retain the last valid sample frequency in case of a loss of the input signal. SyncCheck ensures perfect synchronization and excellent detection of errors, allowing multiple units to be stacked and operated sample-aligned, using word clock. All settings are stored when the unit is switched off.


  • Low latency conversion with only nine samples of delay (in double speed mode)
  • ADAT 24-bit optical inputs, with RME's Bitclock PLL for sample accurate lock. Optical outputs fully compatible with all ADAT optical inputs and S/MUX compatible
  • Includes I64 MADI card for sixty-four channels of MADI I/O
  • Digital input/output trim, with a range of 6dB per input/output
  • SyncCheck technology checks clock synchronization
  • MIDI I/O ports
  • Sixteen LED level meters with seven LEDs per each meter
  • Included remote control for store/recall, volume and DIM
  • All settings are stored permanently
  • Fully remote controllable via MIDI or MADI
