Information
The
Orban 672A is a single-channel eight-band quasiarametric
equalizer of high professional quality. It is equipped with
graphic-type EQ controls providing up to 16dB of reciprocal
boost or cut. The center frequency and bandwidth of each
band are continuously variable to enable precise control of
the audio spectrum. Wide-range high- and low-pass filters
(12dB/octave) follow the EQ section for added versatility.
When these filters are overlapped (200-2000Hz), the
672A can
be used as a combined graphic/parametric equalizer and
tunable electronic crossover. Separate lowpass and highpass
outputs are provided for this purpose.
The
672A has an electronically-balanced bridging input, and
unbalanced outputs (which can be balanced by the addition of
optional output transformers). Input, outputs, 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 "peaktretching"
overload detector, so that peak clipping can be detected and
corrected before it becomes audible.
The flexibility offered by the
672A makes it a particularly
powerful tool in nearly all areas of audio: sound
reinforcement, public address, recording studio,
broadcasting, motion picture sound, disco, theater.
The
672A 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
672A are fully described in
this manual. It will familiarize you with the unit's
potential and enable you to imaginatively use the
672A for
your specific installation and application.
EQ Section
Eight bands, each with TUNING and BANDWIDTH control + l6dB
equalization range Reciprocal curves
Each band tunes over 3:1 frequency range "Q" is variable
between 0.5 and 10
"Tic" marks on TUNING and BANDWIDTH controls guide you to
octave-band graphic equalization settings
Bands are totally non-interacting
LP/HP Filter Sections
Each section is continuously tunable over 100:1 range in 2
decades
Each section is independently switchable l2dB/octave slopes
Separate highpass and lowpass outputs permit use as full
electronic crossover in the range of 200-2000Hz
General
l2dB available gain
Very low noise and distortion
High slew rate for minimum TIM (SID)
"Peak-stretching" overload lamp warns of clipping anywhere
in equalizer before distortion is audible
EQ controls are long-throw dust-shielded sliders for good
resolution Industrial-grade parts and construction,
including socketed IC's RFI suppression on input, output,
and power leads Balanced output optional (order retrofit kit
as required)
Holes for XLR-type connectors are provided
