SIGNAL SWITCH: PRE / POST FADER or FIXED-VARIABLE
The "SIGNAL" switch is located on the back panel in the ”LINE OUTPUTS” field.
The line out signal may be sourced from two different positions inside VIOLECTRIC DHA V590.
If you want to use the activated input signal as is, maybe to source a unit with its own attenuator or
a recording device, then the “PRE-FADER” or “FIXED OUT” mode is the right choice. Here, the input
signal is routed directly to the line outputs without any alteration from the volume attenuator.
If you like to operate you VIOLECTRIC DHA V590 as pre-amp device of outstanding quality to drive
some active speakers or power amps, then “POST-FADER” or “VARIABLE OUT” is the weapon of
choice. Now, the line out signal is attenuated by the volume control of VIOLCTRIC DHA V590.
LINE OUT GAIN ADJUSTEMENT (LEVEL ON THE LINE OUTPUTS)
The level of the activated input is buffered and routed unaltered in its level to the line outputs.
To adapt the level perfectly to the subsequent device(s) the "LINE OUT GAIN" switches are useful.
The operation is similar to the setting of the headphone amp pre gain described on page 18.
You may set gain or attenuation in a range of -18 / -12 /-6 / 0 / +6 / +12 / +18 dB.
Hint:
The unbalanced Signal has always -6 dB less level than the balanced signal!
SIGNAL PROCESSING
inside your VIOLECTRIC DHA V590 is always unbalanced. This is no disadvantage as the
so called “fully balanced” signal processing often generates more issues that solving them.
It is not possible to preserve a reasonable symmetrical integrity of a signal inside a complex
apparatus like DHA V590.
Further, only the unbalanced signal processing is capable to use the device also as a converter
between unbalanced and balanced signals.
With your DHA V590 you will be able to feed an unbalanced signal and to listen with your balanced
or single ended headphones. Further, you can feed subsequent devices from the unbalanced
and/or balanced line outputs.
You may also feed a balanced signal and listen to it with your balanced or single ended headphones.
Simultaneously you may again use the unbalanced and/or balanced line outputs.
