ERROR REPORTING:
To ensure error-free operation and not to harm your valuable headphones in a comprehensive way
your VIOLECTRIC DHA V590 is equipped with a number of protective circuits:
- During powering on there is a five seconds delay to protect your headphones from possibly
unwholesome noises. After the time the headphone outputs are switched to the amp.
Also, the instant cut-off after powering off is intended to protect your headphones.
- DC voltages are no good part of the output signal and must be avoided. If such are detected, the
headphone sockets are cut from the electronics and the ”PROTECT” LED is switched to red.
When the DC voltage has vanished, the amp will automatically return to “normal” operation.
- Overload causes distorted output signals and is also harmful for the headphones. If an overload
was detected, the headphone sockets are cut from the electronics and the ”PROTECT” LED is
switched to red. When the overload disappeared, the amp will automatically return to “normal”
operation.
- All errors will also reset when the unit is switched off and on again.
In case that there is still an error condition the protecting circuits will keep the error mode and
the status LED is red.
RESET OF THE PROCESSORS
Many internal procedures are enabled by processors.
If - of any reasons - nothing seems to work as it should anymore,
follow these instructions to come back to DEFAULT SETTINGS:
Push and hold the “ANALOGUE INPUT” button whilst powering the unit.
Soon after all LEDs on the front panel will light up.
Now you can release the “INPUT SELECT” button as all settings had been reset to default.
