Control Elements
Working on established inter-channel phase principles, the
STEREO WIDTH control increases the subjective soundstage
width of any stereo source. The off-centre signals of the stereo
source are detected and fed back phase inverted to the opposite
channel. This effect can be applied to overall mixes as well as to
single instruments.Very interesting is the spreading of the stereo
image of overhead mics of drums-sets, choruses or horn sections.
The Surround Processor section is independent from all other
processes and is not affected by the ACTIVE buttons or PROCESS
DEPTH controls. To deactivate the effect of this section, the
STEREO WIDTH control should be set fully counter clockwise. In
standard applications a STEREO WIDTH setting above the
2 o’clock position is not recommended for complete mixes.
However,such settings can produce some very interesting special
effects for single instruments.
Special care has gone into the design of the power supply of the
VITALIZER – the better it is, the better the system works. In an
audio system,this translates into better sound quality,lower noise
and lower distortion.
The power supply is based around a 15VA toroidal transformer
and is designed to minimise induced hum and noise due to the
lack of an air-gap.
The primary voltage may be selected between 230 V / 50Hz and
115 V / 60Hz by means of a recessed slide switch on the rear panel
and a rear-panel ground-lift switch is fitted for use where ground
loops are causing hum problems.When the Gnd Lift switch is set
to off,the circuit ground is isolated from the chassis ground.
The detachable power cord is a standard 3-wire type fitted with
an IEC mains connector; the transformer, power cord and mains
connector have VDE,UL and CSA approvals.
The fuse has a value of 315mA for the primary voltage.
On the secondary side of the power supply, an RC combination
is used to filter out noise and hum voltages. Both half-waves are
smoothed with 4000 microF capacitors in the positive and nega-
tive supply path, and both lines use precision voltage regulators
for optimum stability. Deviations of only a few millivolts can
impair audio quality, introducing artifacts such as loss of stereo
imaging or a diffused sound character.
