By now we recommend the
“Tenor” chip-set for Windows applicatons
and the
“X-Mos” chip-set for Mac users.
The
192 kHz
modules are equipped with a top-notch converter offering
a 115 dB dynamic range and
–103 dB THD+N, along with significantly
improved analog output circuitry.
Please note:
-
The digital input has priority over all other inputs and will mute these
when a valif digital signal is detected
-
When a USB cable is inserted, it may be required to restart running
media applications on the host.
-
Volume control of the host application should be set to 100%.
Too loud ? Too soft ? The PRE-GAIN method
The V280 is specially designed to drive headphones. Headphones
however can present load impedances from 8 to 2000 ohms and
efficiency ratios from 85 to 115dB per milliwatt. Thus it can be quite
tricky to fulfil all demands, since...
… owners of high-effectivity headphones will rarely set the volume
control higher than 9 o'clock in order to exclude hearing damage, while
... the maximum setting may still be too soft for low-efficiency
headphones, but
… all users expect highest quality at lowest noise and distortion.
Thus, the
circuitry
must adapt itself as the headphone won't !
