Use the
OPERATING LEVEL
switch to adapt the VIRTUALIZER PRO to different operating levels. You
can select a -10 dBV semi-pro level used for home recording and a +4 dBu level used in professional
studios. The level indicators on the front panel are automatically adapted to read the selected nominal
level, i.e. an optimum operating range of the meters is always guaranteed.

These are the VIRTUALIZER PROs analog
INPUTS.
The VIRTUALIZER PRO has both XLR and jack
inputs and outputs. Each XLR and jack set are wired parallel and can be used either balanced and
unbalanced.

Please take the time to make a note of the
SERIAL NUMBER
in the space provided on the enclosed
Warranty Registration Card. Put the instruction manual in a safe place and return the completed
Warranty Registration Card to us within 14 days of purchase, making sure that the dealer stamp
has been acquired (certain countries only).

This is the
MAINS CONNECTOR / FUSE HOLDER / VOLTAGE SELECTOR.
Before you connect the
unit, please make sure that the displayed voltage corresponds to your Mains supply. Please note that
the AC voltage selection is defined by the position of the Fuse Holder. If you intend to change the
operating voltage, remove the Fuse Holder and turn it by 180 degrees before you reinsert it. Matching the
two markers monitors the selected voltage. Please note that, depending on the mains voltage supplied
to the unit, the correct fuse type and rate must be installed (see chapter 6.5 SPECIFICATIONS).
Please use the enclosed mains cable to connect the unit to the mains power supply.
+
Please note that not all appliances can be used with different mains voltage ratings. Please
check the description on the back of the unit and the box.
1.4 The effect algorithms
In a digital effects device all effect programs are based on algorithms computed by a Digital Signal Processor
(DSP). How does this work? A DSP can perform an enormous number of binary computations in a minimum
amount of time. The binary computations used to generate an effect as part of a program are determined by a
so-called algorithm which represents a rule for computing numerical values that are exactly specified for each
effect type. For example, reverb algorithms differ from chorus algorithms in their programming. Plainly speak-
ing: each effect is based on a specific algorithm which processes the input signal (converted from analog to
digital before). All of this work is done by the DSP. Once the effect has been generated and added to the input
signal, the digital music signal is converted back to analog by means of a D/A converter.
The VIRTUALIZER PRO permits the change of as many as five parameters which influence the sound in
different ways. This means that for some algorithms the parameters are chosen by using key combinations
with
ENGINE L
and
ENGINE R
. In these cases a combination of
ENGINE L
and
ENGINE R
with the
EDIT A
and
EDIT B
key will not mean that only one channel is affected. The combination
EDIT A ENGINE L
is a
different parameter than the combination
EDIT A ENGINE R
, these parameters will be changed on both
channels. With a reverb effect (like PRG 1)
Edit B
ENGINE R
does not mean that the right audio channel is
processed, but that the second
Edit B
parameter (with Prg.1: High Multiply) is adjusted.
The only exception is the DUAL MONO (PARALLEL) effects, which produce another effect in the left channel
