8-Channel, 24bit/192kHz AD/DA Converter

Show full description »

!! Now 192kHz as standard !!

The all-new Rosetta 800 takes two of Apogee's most celebrated products and the latest in high-definition digital and combines them into one impressive package. The Rosetta 800 gives you eight channels of superior AD/DA conversion at sample rates of up to 192k, Apogee´s "SoftLimit", "UV22HR", and our advanced “Intelliclock”. The result is a premium digital recording solution that is built for the professional recording facility yet economical enough for the project studio.


  • 8 channels of premium 24-bit AD/DA conversion
  • Sample rates up to 192kHz
  • 8 channels of AES, ADAT I/O
  • Optional Firewire card for compatibility with OS X, and Windows XP
  • "Soft Limit" for maximum digital level without overs
  • "UV22HR" for superior dither to 16-bit

SoftLimit: Maximize Levels, Minimize Overs

One of the greatest difficulties in digital recording is getting an adequate level without clipping and unwanted distortion. With Apogee's SoftLimit, you can maximize digital output levels without overs.

UV22HR: Dither Down with 24-bit Detail

UV22HR is Apogee´s industry standard technology for reducing the word-length of a high-resolution digital signal to 16 bits for the internet and CD mastering. UV22HR is also being employed to produce dramatically improved internet and computer audio content without increased file sizes or data rates.

Intelliclock: Dual Stage Jitter Reduction

Another essential for outstanding digital recording is maintaining an ultra-low-jitter, clock signal. To accomplish this, Rosetta 800 utilizes Apogee's Intelliclock. Intelliclock is really two clocks in one. A fast-responding ´read´ clock, with a wide locking range, fills a dedicated FIFO buffer, while an ultra-low-jitter ´write´ clock writes the data out of the buffer, and is used to clock the converters.

Legendary Apogee Conversion in High-Definition

The most crucial component in the digital recording environment is high-quality conversion and the most trusted and desirable converters are made by Apogee. With up to 192kHz as standard, the Rosetta 800 combines Apogee's legendary conversion quality with flexibility that complements any digital audio workstation.

Firewire for Future Connectivity

Rosetta 800 has room for expansion. With the optional Firewire card installed (available later this year), you'll be able to connect the Rosetta 800 natively to any Firewire input device, without the need for additional hardware.

Price Matching

Dolphin Music brings you the best music gear at the best price. We are committed to superior customer service and have extensive product knowledge. However, in today’s market we may not always be aware of all the price fluctuations of the products we sell. So, we offer competitive price matching.

Please fill in the following form to request a price match.

What prices we will match?

We will compare prices for new, direct from manufacturer items, excluding any add-ons, options, or other special features which may affect price.

The item must be new and must be the exact same make and model (ie, the same size, version, etc.).

Since our postage charges are lower than most of the shops, the comparison price must be a "delivered cost" to the consumer.

If we are unable to verify the previous condition, we will notify you that we require additional information to verify the Price Match request. Our goal is to make this policy simple and hassle-free. We are committed to responding to your requests quickly.

The price you have found must be the Internet Retailer's regular, advertised price for a current and available item. The price you found cannot be a closeout, discontinued, blemished, year-end, inventory reduction, or any other type of advertised sale price.

Price Matching requests may not be combined with any other promotional discounts, specials or other price incentives.

Prices and price sources you have found which do not meet the above criteria or in which incomplete or inaccurate information is provided to us, will not be approved for our Price Match.
