BUS
LIMITERS
Each DTC™ card comes with thirty-two look-ahead bus limiters. The limiters
can be arbitrarily linked to accommodate mono, stereo, or multi-channel signals.
Each limiter has a set of "anti-breathe" controls which negate the
"pumping" effect that results when a traditional limiter is used
on difficult source material. These features combine to provide transparent
multi-channel limiting of the console busses (or any other signal that you
need to limit to a maximum level before the next stage of processing). An
advantage to this bus limiter is transparent response with Ceiling, Release
and Output Gain controls for undetectable processing. Input and Gain reduction
meters are provided on all thirty-two bus limiters.
AUDIO
LOOPING
Each DTC™ card provides an "audio looping" feature of twenty
seconds for “in console” sampling. This exclusive Harrison feature
allows any audio signal to be sampled and looped indefinitely while the user
manipulates the signal. When used with companion IKIS™ software, the
Audio Looper becomes a Super Looper. Press any PFL switch to route its source
audio to the looper’s input and start recording. Pressing the AFL on
the same channel ends the recording process and substitutes the looper’s
output as the signal source. Now you have a source signal even after your
talent goes for coffee.
ZERO-PHASE
LINEAR EQ
Zero-Phase Linear EQ provides sixty-four bands of equalization without the
phase shift. The Linear EQ is specifically designed for removing trouble frequencies
while allowing control of the remaining bands. Each of the sixty-four bands
can be individually adjusted, or you can use the "stiffness" control
to apply broader changes similar to adjusting the "Q" control of
a traditional EQ band. Each band can be "locked" in place so that
it will ignore the effects of the stiffness control. This allows you to notch
out selected frequencies and then continue to apply broad EQ settings to the
incoming signal.
MULTI-BAND
COMPRESSOR
A multi-band dynamic EQ specifically designed to function as a multi-band
compressor. The Multi-Band Compressor can be selected to be a two, three or
four band device with full spectrum frequency control for each band. The controls
also include separate meters threshold, ratio, attack and release controls
per band. The frequency ranges and maximum gain reduction (depth) of each
band can be manipulated directly on the graphical display. The display also
serves as a meter showing the dynamic EQ curve that is being applied to the
incoming signal.
HARMONIC
NOTCH FILTER
The Harmonic Notch Filter is a highly specialized, multi-band dynamic dip
filter designed to attenuate noise. The user is able to quickly and easily
apply only as much harmonic filtering as needed for the application. Each
of the eight harmonically related bands has an In/Out switch for signal comparison.
Each harmonic band includes four internal bands providing a thirty-two band
filter set. Minimum and maximum depth settings allow for more flexible signal
targeting. Additional dynamics controls include variable threshold, attack,
and release times. Full spectrum frequency and Q controls are also provided.
DE-ESSER
The DeEsser tool provides quick and easy de-essing. You can manipulate the
sibilance frequency range as well as the maximum gain reduction directly on
the graphical display. The display also serves as a meter showing the dynamic
EQ curve that is being applied to the incoming signal.
LEVELED
EQ
The Leveled EQ is a dual four-band, gated EQ. The Leveled EQ is specifically
designed to provide dynamic switching between two EQ settings on signals with
a wide dynamic range where it is necessary to EQ the signal at low levels
differently than the signal at high levels.
Variable settings for threshold, crossover rate and hysteresis control the
transition between the EQ's creating a gentle crossfade. Each band of EQ in
both banks has multiple shape selections - bell curve, graphic bell, notch,
search, low shelf, high shelf, LP filter, and HP filter.
SUBHARMONIC
SYNTHESIZER
The Subharmonic Synthesizer generates ultra-low frequency content based on
the existing low-frequency content of the incoming signal. Individual level
controls are provided for 2 subharmonic oscillators as well as an overall
synth level and general "LF boost" control. There are also controls
for the crossover frequency and whether the resulting output should be full-range
or subharmonic content only.
TELEPHONE
FILTER
The Telephone Filter allows the user to add color and texture to a signal
to simulate sound through a telephone line. The filter provides a typical
300 to 3kHz "steep side" filter with additional controls such as:
• Crackle Generator
• Density
• Width and Half Width
• Even and Odd Distortion Controls
• Aliasing Level and Density
• AM Modulation
• Frequency Controls
• Hiss Level
• Threshold
CROSSOVER
EQ
The Crossover EQ is a dual four band dynamic EQ. The Leveled EQ is specifically
designed to provide dynamic switching between two EQ settings on signals with
a wide dynamic range where it is necessary to EQ the signal at low levels
differently than the signal at hi levels. Upper and Lower threshold settings
determine the crossover range. Crossover time can be adjusted to create a
smooth transition between the two EQ's. Odd and even distortion can be added
to create a "warm" analog response or create a desired effect or
texture. Each band in both EQ banks has multiple shape selections including
bell curve, notch filter, search filter, hi shelf and low shelf.
INSERT
The Insert tool provides a flexible "insert point" for an external
device. The input to the device, output from the device, and the bypass path
each have four bands of parametric equalization and a comprehensive set of
polarity, delay and trim controls which, when combined with a smooth cross-fade
function, allow you to transparently insert and remove an external piece of
gear from the signal chain.
MULTI-BAND
EXPANDER
A Multi-Band dynamic expander specifically designed to function as a multi-band
expander. It is often used to remove hiss often found in the high end of a
track. The Multi-Band Expander can be selected to be a two, three or four
band device with full spectrum frequency control for each band. The controls
also include separate threshold, ratio, depth, attack and release controls
per band.
TRAINING
DENOISER
The new "Learning DeNoiser" tool is a simple-to-use denoising tool.
Loop a short noisy segment in the Audio Looper and click the "train"
button. "Window" and "Release" controls adjust the amount
of denoising based on the level of the input signal.
DIALOG
MASSAGER
The new "Dialog Massager" is a
multiband dynamic EQ that is perfect for cleaning up those difficult dialog
takes. Each of the 4 frequency bands can ramp between 2 independent EQ curves
based on the amount of energy in the band. De-essing, de-noising, special
effects and "audio forensics" tasks are possible with this powerful
tool.
STADIUM
SIMULATOR -- Coming Soon in 2005!
The "Stadium" tool simulates the sound of a multi-element speaker
system in a large, reverberant area.
