Information
The Orban 642B Parametric Equalizer/Notch Filter is an
efficient and powerful tool for a wide range of creative and
corrective equalization applications.
• Full parametric operation with no interaction between
parameters.
• True infinite-depth notch filtering (made possible by the
642B’s constant-Q design).
• Each band is continuously tunable over a frequency range
exceeding 20:1.
• Tuning ranges of bands overlap significantly to maximize
versatility.
• Verniers on the FREQUENCY controls facilitate fast,
precise tuning of sharp notches.
• +16dB boost to infinite cut (~45dB typical) available in
each band.
• Bandwidth can be varied from a broad (Q = 0.29) curve to a
sharp (Q = 5.0) curve.
• Dual 4-band or mono 8-band configuration can be selected
with the front-panel cascade button.
• Continuously tunable 18dB/octave high-pass filters and
12dB/octave proprietary Automatic Sliding Besselworth™
low-pass filters provide full flexibility while retaining
maximum musicality.
• Noise and distortion specs are significantly better than
16-bit digital.
• Input signal gain can be adjusted throughout a range of
+14dB to -©o.
• overload lamps warn of overload when the output of any
internal amplifier is within 1dB of its clipping level.
• Extensive RF suppression on input, output, and power leads.
