Extremely low distortion limiting is accomplished by the
use of type 1537A VCAs in each band coupled with individual
precision comparator/pulse charge gain control circuits. The
attack time is sufficiently fast to prevent audible overshoot
clipping (with the help of ALT) but is slow enough to prevent
"hole punching" by transients such as record pops, etc. The
limiting thresholds for all bands are equal and are DC
programmed by the ALT bus. Release time is likewise equal and
DC controlled.
2.5 Tracking Control
TRACKING locks the gain control signals together for each
band. This provides the most stable stereo image . However,
greatest average loudness is acheived when the two channels are
operated independently.
2.6 Output Ceiling Control
The calibrated OUTPUT CEILING control is the only control
on the studio Dominator that is not a DC control. It is a
precision attenuator that is adjustable in ldB steps from -2dBU
to +21dBU. In-between levels can be accomplished by an internal
trimpot if desired. This setting represents the
actual peak voltage of the output signal, not RMS voltage. This
limit will not by exceeded under ANY conditions of limiting .
The RANGE control selects HI or LOW range of the OUTPUT CEILING
knob.
2.7 Factory options
To adapt the Studio Dominator to the widest varjety of
applications, several factory options are available.
a) Pre/De-emphasis - Allows insertion of a precise
preemphasis curve prior to limiting. Oeemphasis is
jumper selectable to restore flat response if
desired. 75 uSee is standard, others available.
b) Lowpass Filter - In addition to the above, an
overshoot corrected lowpass filter of exceptional
quality may be installed to restrict bandwidth for
broadcast or digital recording. 15kHz is standard.
