The Equalizer section of the VXP contains a 4 Band Semi-Parametric
Equalizer. There is also available Low Mid Narrow Q Select and High
Mid Narrow Q Select, as well as, an 80Hz filter. An In/Out switch is
provided for auditioning the effects that the equalizer settings are having on
the signal being processed.
LOW SHELVING
The 100Hz control adjusts frequencies 100Hz and below. The operator
can boost (up to +12dB) or cut (down to -12dB) those frequencies below
100Hz. The term Shelving describes a filter that adjusts all frequencies
above or below a center frequency.
LOW MID RANGE
The LOW MID-RANGE controls those frequencies in the lower mid
portion of the frequency spectrum. The controls provide for continuous
sweep from 90Hz to 700Hz. The outer concentric knob adjusts the desired
frequency up to +12dB or –12dB, if desired. The inner concentric knob
adjusts the frequency.
HI Q
The position of the HI Q switch determines the width (shape) of the
frequency being affected when boosting or cutting at the selected frequency
with the level control. The widest bandwidth effect is available with the HI
Q switch in the “
OUT”
(UN-depressed) position The value in the “
OUT”
(UN-depressed) position is a Q of 0.5. By depressing the HI Q switch the
width of the frequencies which are acted upon become greatly narrowed
and the result is a much more precise tuning of the selected frequencies.
When the HI Q switch is engaged the value changes to 2 and the width of
