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.
