Digital Inputs (OPT, COAX, USB)
The 200 Pre’s built in DAC (Digital to Analog Converter) uses a high resolution 192kHz Burr-Brown DAC IC.
Since the 200 Pre’s DAC is superior to the DAC in most source components, they will sound better if you
connect them via their digital output rather than their conventional analog line output.
Using the Digital Output on a TV, Blu-ray/DVD Player or Gaming Console
If you connect a TV, Blu-ray player, DVD player, cable TV box, satellite receiver, video streaming device or
gaming console to your 200 Pre you must go to that device's audio setup menu and select stereo PCM (2.0)
output. The 200 Pre’s DAC accepts only two-channel stereo PCM. It does not accept Dolby Digital or DTS
formats.
Opt (Optical)
The optical input is a high speed Toslink receiver with a 25MHz bandwidth. It accepts standard sampling
rates up to 192
kHz-24 bits:
Optical Cable Note
:
192 kHz sampling rates will only play reliably with a short optical cable. Be careful
when handling the optical cable. It has limited flexibility and if you bend it at a sharp angle you’ll impair
its ability to transfer the optical signal from your source to the 200 Pre.
Coax (Coaxial)
The Coax (also called S/PDIF) input connector is an RCA jack. The Coaxial input accepts standard
sampling rates up to 192
kHz-24 bit.
Coaxial Cable Note: The 200 Pre’s Coax input works best with a true 75 ohm cable which typically has
“75 ohm”, “RG6” or “RG59” printed on the cable. Using an ordinary audio cable can make the signal
unstable, resulting in high levels of jitter and even audio dropouts. Most digital coaxial cables with RCA
plugs look like typical analog audio cables, but their electrical characteristics are not always the same.
USB
The USB input is used to connect your 200 Pre to your PC or Mac computer. This allows high quality
playback of any music that is stored on your computer and streaming music services accessed via the
internet. The USB input accepts sampling rates up to 96
kHz-24 bit. The 200 Pre uses the USB 1.1 Audio
standard which allows use of 12’ (4 m) USB cables without any performance penalty. The USB connection is
plug and play with Windows and Mac computers and therefore doesn’t require the installation of any drivers.
