ROSETTA 800 – User’s Guide APOGEE ELECTRONICS Introduction Apogee Electronics’ Rosetta 800 is a multi-channel Analog and Digital converter designed to provide the highest quality signal path for all modern digital systems, while setting a new standard of performance at an accessible price. The following features are included: • • • • • • Sample rates up to 96kHz, upgradeable to 192kHz.
ROSETTA 800 – User’s Guide APOGEE ELECTRONICS Getting Started Quickly CONNECTING POWER The Rosetta 800 accepts an AC input of 100 to 240v AC at a frequency of 50 to 60 Hz. Thus, the unit may be connected to virtually any AC power outlet found worldwide without concern for voltage settings or fuse ratings. RESET To reset the Rosetta 800, power up the unit while pressing the SAMPLE RATE button.

The LED goes out when the Rosetta 800 is powered on. 2) The 176.4 and 192 values cannot be selected on the 96kHz version of the Rosetta 800. The unit may be upgraded to 192kHz operation at any time. 3) A different AES format may be selected for each sample rate range. 4) When clocking to an AES input (i.

ROSETTA 800 – User’s Guide APOGEE ELECTRONICS Navigating the Front Panel - continued 4 5 9) The clock circuitry of a typical D-to-A converter must be designed as a compromise between the ability to attenuate input signal jitter and the ability to accept any bitstream, regardless of it’s stability. The more the clock is allowed to track timing variations of the input, the more jitter remains in the clock at the conversion stage, with the degradation of conversion quality as a result.

Soft Limit transparently rounds transient spikes in a manner similar to analog tape, allowing several more dB of signal to be recorded onto the digital medium. 11) A blinking digital source LED indicates that the selected source is not synchronous with the unit’s clock source.
