Nice
Got the NEOTECH DAC. Smaller USB PWR plug & basically the same as the
older unit. Except the NEOTECH headphone output plug works. The old unit was pure static, run simultaneously with the TOSLINK engaged, with the same static bleeding, regardless, into the TOSLINK with the sensitivity jacked up for a discernible noise floor. The NEOTECH also has a noise floor -- either need be workable at high volume amps fed by: a mixer unit's: cntrl out 22dbu (13 uV) headphone out 19dbu (9 uV) both into mixer from mixer into four J61 tubes @ tube buffers ratings (set for about a quarter the vol: output): Input Sensitivity: 300 ~ 2000MV Output: 3000MV The Issue before was: a) Mixer unit's handling XONAR analogue (RCA jack) outputs b) Mixer unit's handling of DAC/TOSLINK laser carrier unit (initial TOSLINK out provided, additionally and as well from the Xonar Soundboard): Balance impedances were screwed: Non-musical interplay canceling out, stomping all over frequencies between blending the above two. The Fix and result from the NEOTECH DAC: With both NEOTECH output channels, quad speakers: mini-headphone and RCA jacks -- there is no such above disparity between blending both from a mixer board's channel inputs. Both are matched and clean. Thus: One NEOTECH channel to a DBX Compressor: Input - 30V RMS Max Output - 7V RMS @ 1kHz for 5k-ohm load And DBX back to the mixer. I can now expand on RMS voltages, blend the NEOTECH headphone separately, with the mixer for Wet/Dry weighing. I like this TOSLINK data carrier stuff. I set all the software to oversampled rates. Seems a little more crystalline, glassy and the most accurate for higher-end encodes [FLAC] at a lower spectrum of recording media. Five, six stages of software processing the audio, outside and into another three or four hardware stages with mixer, tubes, and compressor: No rules - you got the golden ears or not. It's been nice to say that's settled. Anybody listened to a hi-end $300 DAC unit? |
