orange or green BDA-1
« on: 10 May 2009, 01:35 pm »
 :scratch:,as I'm using the spidf from cdp to the BDA-1,is the upsample led suppose to be ORANGE or GREEN.
I believe I read that if it is orange that it's working at it's best :scratch:.Any users out there that can enlighten me,thanks :dunno:..

Orange is correct, i kinda wish they had given it a green led to match the rest of my led's on all my components.

Actually i think if its coming in at 192k its orange and 176k is green cant remember.

Thanks Lorne,that little black box has to much info for me.
The rackmount 19" in black looks  :bowdown:roadworthy.I have the 26,mps-2 and dac stacked 8).

From the BDA-1 Literature:

•In the BDA-1, 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-1 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.


SO:

The BDA-1 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’ and turn Green or Amber depending on the incoming sample rate. (Green if the incoming is 48 or 96K and Amber if 44.1 or 88.2K)

•If the sample rate coming in is 44K or 88.1K the BDA-1 upsamples to 176K

•If the sample rate coming in is 48K, or 96K the BDA-1 upsamples to 192K.


The upsample feature works on all inputs (including the I2S USB input) assuming the Upsample button is push.

If the incoming signal is 'native' 176K or 192K then no upsampling occurs.

Hope this helps explain it better?

If a regular CD is played through the BDA-1 and it shows 44.1 kHz on the BDA-1 I can see from the above that is the upsampling button is engaged it bumps it to 176 kHz. There is also a button called 'LOCK' that is also lit...what does that mean and should it be on? Thanks.

Yes it should be on ... 'LOCK' indicates that the signal is strong enough for the DAC in the BDA-1 to lock on to the signal.

Blue is so much better.

Drummer,

44.1 + 44.1 =  88.2
88.2 + 88.2 =  176.4

so 44.1 and 88.2 have the Amber LED. if the incoming signal is ALREADY 176.4 khz (which is 88.2 + 88.2) there will be no upsampling by the BDA-1.

---------------------------------------------------------------------------------------------------------------------------------------------

48 + 48 = 96
96 + 96 = 192

so 48 and 96 will have the Green LED. if the incoming signal is ALREADY 192 khz there will be no upsampling anymore. the BDA-1 also accepts 32 khz which will have the Green LED, too.

Al,all figured out in May,thanks.
Now she sits on the rack,waiting to see which  digital highway she'll take and convert.
Had the BCD-1 in there for awhile,but preferred the BCD-1 analog to the 26.
Too much YES-NO,YES- NO,to my ears,they're that closeand that's a good thing as I really like the BCD-1.

right, Drummer. the BCD and the BDA are soundwise very, very close. if i would make a blind A/B test i am pretty sure that i couldn't tell the difference between 'em. :thumb:

i just gave the BDA-1 to my father-in-law. his system is an old NAD/Luxman combination. it took us the first 10 seconds of a song to hear the DIFFERENCE!!! he said "you know what, Alex? this is unbelievable."

the BDA-1 is still at his home...


these are the moments that simply put a smile on my face :D

Werd,

i think it's because to make it easier to differentiate between 32 khz (and up) and 44.1 khz (and up) as the source inputs and the sample rate LED array already have green LEDs.
