█ Line out

This standard XLR connector will provide a balanced line level output signal. It's capable of

driving (very) long leads to mixing consoles, recording equipment, etc. The line out is

surrounded by various controls for maximum flexibility.

● pre/post

before (pre) or after (post) the EQ.

● level : adjust the output level by +/- 9dB

● phase

: change the phase of the output signal by 180 degrees*.

● ground lift

any ground loop issues.

Note: There are a few examples

why changing the phase of the

line out signal might be

necessary. Bad wiring, specific

distances from the FOH

speakers when using a speaker

cab too, or wrong settings within

a mixing console to name a few. These issues will result in a phase shift, recognizable by a

vague tone or complete signal loss. Flipping the phase button will usually resolve the issue.

All three functions of the buttons found on the front panel (mute, fx loop and EQ) can be

controlled externally by the optional footswitch. For convenience and the ability to use a

widely available type of cable, a RJ45 connector is used. The control is fully parallel. If you

prefer to build your own footswitch, or integrate these functionalities into a larger control

system, the pinning is available in appendix A below or on http://debontamps.com/manuals/

The Vidur preamp comes with three output connectors.

● Jack output, (un)balanced : A 6.3mm (1/4") standard jack connector. Can be used

unbalanced (TS) or balanced (TRS). Using the jack output will mute the XLR outputs.

● XLR outputs, balanced (2x): These

standard XLR connectors are wired in

parallel. Since most solid state power

amplifiers come as two channel, two input

devices, the second XLR is there simply

for convenience.

: sets the point where the signal is tapped from inside the preamp;

: (dis)connect pin 1 from the XLR connector. This will effectively cure
