THE BALANCED HEADPHONE OUTPUT
VIOLECTRIC DHA V590
offers a dedicated headphone output
to connect balanced headphones.
The output is situated on the front
panel and comes as a gold plated
4-pin XLR socket.
THE UNBALANCED HEADPHONE OUTPUTS
The DHA V590 offers two stereophonic headphone outputs,
each equipped with a 6.3 mm (1/4") TRS jack socket.
Because DHA V590 has a 4-channel amplifier (2 x stereo),
each socket is driven by a dedicated stereo amplifier
Please note:
The RIGHT phone jack is connected to the in-phase stereo signal, whereas the left phone jack is
connected to the 180
0 phase shifted signal.
HINT:
To protect the headphones from interferences during powering on/off the outputs are cut during
powering on. This procedure takes about five seconds. When powering off the outputs are cut
instantly.
THE LINE OUTPUTS
THE UNBALANCED LINE OUTPUTS
are located on the rear panel of the unit and are marked as “RCA OUT L/R”.
Gold-plated RCA connectors are implemented here.
THE BALANCED LINE OUTPUTS
