RME ADI8QSM
ADI-8 QS with I64 MADI Installed

ADI8QSM

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 truely unique. The ADI-8 QS is RME's reference - highest performance in every detail, at an unbeaten price/performance ratio!

Features:

• 8-Channel AD converter, fully symmetrical design, 117 dBA
• 8-Channel DA converter, DC-coupled signal path, double balanced output, 120 dBA

This version includes the 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.
