ERROR EVALUATION
In order to guarantee flawless operation and optimum protection of your
valuable headphones, the V281 is equipped with various protection
circuits:
- the delayed activation of the headphone outputs upon power-up
prevents your headphones from potentially adverse signal peaks
from the preceding circuitry.
In a similar manner, the headphone outputs are instantly
disconnected when turning power off.
- Adverse DC voltage should be kept from your headphones at all
times. If DC is detected, the headphone outputs will be
disconnected, indicated by the red “MUTE” LED flashing and the
green “HEAD” LED lit. The detection interval is about five seconds.
If DC disappears during this period, the unit will resume normal
operation automatically.
-
Overloading (i.e. increased distortion) must be avoided in favour of
your headphones as well. If overload is detected, the headphone
outputs will be disconnected, indicated by the red “MUTE” LED
flashing and the green “LINE” LED lit. The detection interval is
about five seconds. If overload conditions resolve during this
period, the unit will resume normal operation automatically.
FACTORY RESET
