A class leading DAC for your home system
Designed from inception to become a class-leading Digital to Analogue Converter (DAC), the Optoma DAC80 simply extracts every last nuance and detail from your digital music collection. It is destined to become the cornerstone of your high-end audio system with three different digital connectivity options and the capability to connect four devices concurrently, the DAC80 is an audiophile’s digital music hub.
Resolution
The DAC80 supports virtually all digital file formats including the very highest quality 192kHz/24-bit PCM studio master or lossless quality music files stored on your computer. The standard resolution digital devices like your TV and games console will benefit from extra detail, depth and clarity.
Digital input stage
At the heart of the DAC80 lies an audio grade toroidal transformer that provides ultra-stable and low noise power to the audio boards. The first of which is its digital input stage, which operates in an asynchronous mode independent of any timing errors associated with the incoming digital audio stream. By synchronizing the incoming data to an internally referenced timing signal generated by an exceptionally stable circuit, the re-clocking circuit’s accuracy is such that any negative timing errors (jitter) are reduced to near theoretical limits. The 24-bit, 192kHz DAC stage then accurately converts the digital audio data back to an analogue signal at its native sampling rate. No up-sampling or other questionable data manipulation is ever employed maintaining the purity of your music – just as the artist intended.

Next is the DAC80’s digital 32-bit volume control which offers extremely precise channel tracking. Unlike more common digital volume controls operating at 16 or 24-bits, the 32-bit dynamic range of the DAC80's volume control avoids any loss of low-level resolution.
Finally, there is an analogue buffer preamp stage of "minimalist" design that offers a signal path approaching a "straight wire with gain" level of performance. Combined with top quality parts and a full 2.0Vrms signal level at the RCA outputs, the preamp section of the DAC80 ensures that only the purest of analogue music signals will ever be presented to your preamplifier.
