BDA-3 Sample Rate Explanation
• In the BDA-3, the sample rate is increased from the input sample frequency (48K, or 96K upsamples to 192K.
• The 44.1K or 88.2K upsamples to 176.4K).
The 16 bits of depth (the CD standard) is increased to 24 bits.
OPTIONAL UPSAMPLING FEATURE
A very unique feature of the Bryston BDA-3 External DAC is the ability to disengage the upsampling feature. You can compare an upsampled signal with a non-upsampled signal simply by engaging a switch on the front panel. This feature is functional when using sample rates of 44.1K, 88.2K, 48K, and 96K.
The BDA-3 tells you what is ‘COMING IN’ not what is going ‘out’.
The Digital Lock light will turn ‘green’ if the digital signal is locked.
The incoming sample rate will be indicated by that LED going green – so if the incoming digital signal is 96K the 96K LED will light green.
If you push the UPSAMPLE button on the front panel then the incoming digital signal will be ‘SYNCHRONOUSLY UPSAMPLED.
•If the sample rate coming in is 44K or 88.1K the BDA-3 upsamples to 176K
•If the sample rate coming in is 48K, or 96K the BDA-3 upsamples to 192K.
The upsample feature only works on SPDIF inputs (not USB or HDMI).
If the incoming signal is 'native' 176K or 192K then no upsampling occurs.
If you want to maintain NATIVE file playback only leave the Upsample button OFF
