Violectric DHA V590² Pro Headphone Amplifier, Preamp, and DAC - Manual (Page 19)

CAUTION
To avoid unwanted level leaps the settings should be altered under the following conditions only:
- the "VOLUME" control should be set to minimum
or the headphone outputs shall be deactivated using the “HEAD“ button
- left and right channel settings should be the same
unless you want to settle the amp for different hearing abilities
Ex-factory, all switches are set to their lowest position - i.e. 0 dB PRE-GAIN - which should be
sufficient for most applications.
THE AMPLIFIER(S)
The input signals are fed to an amplifier stage especially designed for this application, with 2 x eight
transistors per channel. Because of the true balanced operation VIOLECTRIC DHA V590 houses no
less than four of those! All in all, 32 of over 52 transistors of the unit are responsible to process
analogue signals. The channels are physically separated from each other to ensure optimum
crosstalk rejection.
The frequency range covers 5 Hz ... 250 kHz (-0.5 dB) in order to ensure fully linear performance
within the entire audible range. Overall gain is set to 0 dB (unbalanced) or +6 dB respectively
(balanced) to ensure lowest self-generated noise.
ACTIVATING / DEACTIVATING THE HEADPHONE OUTPUTS
Pressing the "HEAD" button will activate or deactivate the headphone outputs.
The white LED shows the activated state.
This procedure is also maintained by the “x2” button of the remote control in the alternative mode.
ACTIVATING / DEACTIVATING THE LINE OUTPUTS
Pressing the "LINE" button will activate or deactivate the line outputs on the back panel.
The white LED shows the activated state.
This procedure is also maintained by the “x4” button of the remote control in the alternative mode.
HINT:
When the "MUTE“ Button of the remote control is pressed, all outputs from DHA V590 are muted,
this concerns the back mounted line outputs and the front mounted headphone outputs.
The front "MUTE“ LED is red now.
The mute may be deactivated separately for the headphones outputs or the line outputs by pressing
the dedicated button on the front panel or on the remote control.
For both ways simultaneously the mute may be released by pressing the “MUTE” button on the
remote control again.
