ULTRA-VOICE DIGITAL VX2496
2. CONTROL ELEMENTS
To avoid internal overloading, the CLIP LED should only
light up during peak level passages. It should not be
constantly illuminated.
The TUNING control lets you determine the frequency range
to be saturated. All other ranges remain unaffected,
allowing the effect to be finely tailored.
To process the whole frequency spectrum, use the FULL
BW button. This makes the TUNING control inoperative.
2.3 Opto compressor
Fig. 2.3: Opto compressor
The opto compressor reduces the dynamic range of
the input signal, i.e. the level difference between soft
and loud passages. Peaks above a certain value are
reduced, smoothing out the sound.
The IN/OUT button activates the compressor. Use this to
directly compare compressed and uncompressed signals.
The THRESHOLD control determines the level at which
the opto compressor starts to compress the signal. Only if
this value is exceeded will the signal be processed. The
dynamics of passages whose levels lie below the threshold
are not affected. The lower the threshold value, the greater
the compression.
The HARD RATIO button sets the amount of signal gain
reduction to its maximum. This produces a highly-
compressed, flat sound. Do not use this function if you
wish to retain the natural dynamics of the sound.
If the FAST button is pressed, the opto compressor starts
compressing very quickly after the threshold is exceeded.
The overall sound appears significantly more compressed
and the result is a very powerful sound.
The RELEASE control determines how quickly the
compression stops after the signal falls back below the
threshold. The longer the release time, the more compressed
the sound will appear to be, but also the more smoother.
The OUTPUT control regulates the output volume of the
compressed signal. The compression process reduces
the level of signal and this control is used to raise its level
again (known as make-up gain).
Certain frequency ranges may be lost during compression.
These can be regained by using the integrated enhancer.
The sound is subjectively rounded off and acquires a new
brilliance.
The six GAIN REDUCTION LEDs display the amount of
compression. The level reduction displayed ranges from
-3 to -24 dB.
2.4 Voice-optimized EQ
Fig. 2.4: Voice-optimized EQ
The voice-optimized EQ is a 3-band equalizer used for
sound shaping. You can boost or cut frequency ranges
in order to equalize weaknesses in the input signal.
Activate the voice-optimized EQ with the IN/OUT button.
Use the TUNING control to select a frequency range
(130 Hz to 720 Hz).
The selected frequency range can be boosted or cut using
the WARMTH control. Cut employs a narrower bandwidth
than that used for boost, enabling you to tailor the filter to
your specific needs.
Use the PRESENCE control to add high and upper-mid
frequencies to the signal (around 1.7 kHz). This helps to
push vocals to the forefront with more presence in the
overall sonic image.
Use the BREATH control to boost or cut typical noises
associated with the voice (e.g. breathing) at around 8 kHz.
The ABSENCE button cuts the level of those frequencies
that cause an unappealing, harsh sound. These lie around
the area of 4 kHz.
2.5 Opto de-esser and master section
Fig. 2.5: Opto de-esser and master section
Sibilance is an unwanted effect that can occur with
some voices, whereby hissing sounds like that of “s”
or “sh” are produced. With the opto de-esser, sibilance
can easily be removed from the signal.
Depress the IN/OUT button to activate the opto de-esser.
The THRESHOLD control determines the amount by which
sibilance should be suppressed. The lower the value, the
more comprehensively sibilance is removed.
Use the CUT FREQ control to select the frequency range
to be reduced.
The ACTIVE LED lights when the opto de-esser is
functioning. The intensity of the LED reflects how hard the
opto de-esser is working.
