I have: dbx drive rack PA -> crown d-45 amp -> 115db/w/m horns. No hiss due to correct gain structure.
Sort of makes my case.
dbx PA specs
From DCX specs
Dynamic range: 109 vs 110dB: you've managed to do it Steve with a unit with the same basic specs, so it must
be possible, something I've been saying, and doing
, for ages.
And just to top it off here's someone else's set of measurements on a stock DCX, abeit using the SPDIF in (44.1k digital silence), so it shows the base noise of the processing and DAC and O/P stage.
and with a 1kHz -3dBFS 1kHz signal.
Note the vertical scale differences between the two images.
Analogue in won't be quite as good but the AD is a good unit (AK5393VS
) and it's still a massive
leap to go from this basic performance to a measured level of 60dB SPL.
From AK5393 datasheet.
My tests will be similar, but using the analogue in. Nothing else to get involved. I can get a stock DCX to loan, but maybe not till late in the week or next w/e. Going away this w/e.
When people continue to post technical rubbish, I will call them on it, no matter how much they scream and try to get me not too. Perhaps if said people did not post this, I wouldn't need to reply, no matter the title of the thread.
