Input global Settings

In the Input menu, you'll find a gain
switch (INPUT Gain) that increases the
input signal by 20 decibels before it is
sent to the digital analog converter. This
means that with the proper cords you
can connect a microphone, an electric
guitar or a record player directly to the
Virus Rack. However, to attain the best
possible sound quality, it is advisable to
patch the signal into an appropriate sig-
nal processor such as a microphone
preamplifier, a mixer, or a guitar preamp
before you route it into the input of the
Virus. Please turn down the Master Vol-
ume knob before you turn input gain up.
Be aware that boosting the signal by 20
decibels increases the level tenfold!
Additionally the Virus is equipped with
an amplifier stage (INPUT Boost), that
can boost the signal level of the two
inputs continuously by up to 36 dB. The
signal is boosted in the digital section of
the Virus, so the noise level of the ana-
log-digital converters increases automat-
ically. Consequently you should dial in
the cleanest, loudest possible signals at
the external sound generator, or use the
INPUT Gain switch.
Since record players have a characteristic
frequency response, we equipped the
Virus Rack with a suitable Phono equal-
izer. It may be activated via the "INPUT
Phono" parameter.

Input Level Indicator

Alternatively, the RATE LEDs of LFO 1
and 2 can also serve as level indicators
for the left and right external audio
inputs. The Virus automatically switches
to this level indicator mode when the
selected SINGLE program accesses the
external audio inputs. The LEDs will flash
rapidly to indicate that the inputs are
being overloaded. You should dial in the
proper level on the device that is send-
ing the analog signals. The reason for
that you want to feed the highest possi-
ble clean signal level to the analog-to-
digital converters of the Virus so that
they will deliver the best possible perfor-
mance ( Siehe "LED Mode" auf
Seite 155).
