Parametric Equalizer
Informacja
The Orban 622A/B are parametric equalizers of high
professional quality. The 622A is a single-channel
equalizer; the 622B is a dual-channel Equalizer. Each
channel contains four parametric equalization bands.
Isolation of the two channels in the 622B is extremely high
(greater than -90dB, 20-20,000Hz). Therefore, each channel
may be used independently without danger of audible crosstalk.
The 622 is equipped with rotary-type EQ controls providing
up to 10dB of boost and better than 40dB of cut. The
controls are non-reciprocal, providing musically useful
"constant-Q" characteristics, and permitting the Equalizer
to be used as a notch filter. The center frequency and
bandwidth of each band are continuously variable to enable
precise control of the audio spectrum.
Each channel of the 622 has an electronically-balanced
bridging input and an unbalanced output which can be
balanced by the addition of an optional output transformer.
Input, output, and power line connections all contain
effective RF filtering. l2dB of gain is available. AM
potential overload points in the Equalizer are monitored by
an extremely fast "peak-stretching" overload detector, so
that peak clipping can be detected and corrected before it
becomes audible.
The flexibility offered by the 622 makes it a particularly
powerful tool in nearly all areas of audio: sound
reinforcement, public address, recording studio,
broadcasting, motion picture sound, dance bars (discos),
theater...
The 622 easily meets the quality, performance, and
reliability requirements of the demanding professional, and
is also well-suited for use in semi-pro or audiophile
applications.
The controls and features of the 622 are fully described in
this manual. It will familiarize you with the unit's
potential and enable you to imaginatively use the 622 for
your specific installation and application.
