Available Filters
There are eight configurable filter types available:
o
All Pass: Frequency range is 20.00Hz to 20.00kHz. All pass changes the phase of
the audio signal at the set frequency.
o
CD Horn: Horn drivers commonly used in arrays in arenas and auditoriums have an
inherent 6dB/octave high frequency rolloff. The CD Horn EQ compensates for this
characteristic.
o
High Pass: Selectable frequency cutoff is 20.00Hz to 20.00kHz. Rolloff is 12dB/-
octave. Level is fixed at 0dB.
o
High Shelving: Provides boosting or attenuation of frequencies above a designated
frequency. The transition between the spectrum above and below the designated
frequency occurs at a fixed 6dB/octave rate. The gain or loss above the corner
frequency is adjustable to +/- 15dB.
o
Low Pass: Selectable frequency cutoff is 20.00Hz to 20.00kHz. Rolloff is 12dB/-
octave. Level is fixed at 0dB.
o
Low Shelving: Provides boosting or attenuation of frequencies below a designated
frequency. The transition between the spectrum above and below the designated
frequency occurs at a fixed 6dB/octave rate. The gain or loss below the corner
frequency is adjustable to +/- 15dB.
o
Notch: Center frequency range is 20.00Hz to 20.00kHz. Bandwidth is from .05 to 5.00
octaves in .01 octave increments. Level is fixed at -80dB.
o
PEQ (Parametric Equalizer): Center frequency range is 20Hz to 20kHz in .01Hz
increments. Bandwidth is .05 to 5 octaves in .01 octave increments. Level range is -
15 to +15dB in 0.5dB increments.
Compressor Button
The Comp button opens the Compressor window.With the compressor you can change the gain
transfer characteristics of the signal path and control the dynamics of a signal.
l Select the Enable Compressor check box to activate the compressor.
l Post Cmprs Gain: Adjust the compressor gain with the gain slider.
l The graph reflects the input/output decibel levels with the gain setting you select.
l Threshold determines the RMS level at which the compressor begins to operate.The range
is from -60 to +20dBu. Default is 0dBu.
l Ratio changes the rate of compression applied to the input signal as the signal exceeds the
threshold level.The range is 1:1 to 1:20dB. Default is 1:1
l Attack determines how quickly compression is enabled. It is calibrated in milliseconds.The
range is 0 to 100ms in .5ms steps. Default is 10ms.
l Release determines how quickly compression is disabled.The range is 100ms to 2 sec-
onds, in 10ms steps. Default is 500ms.
l Input meter: This peak meter shows the level of the signal as it enters the compressor.
l Compression meter: This peak meter shows the instantaneous compression value at a
given time.
The Mute button silences each processing channel independently.
Gain: The slider independently adjust the gain level for each processing channel. Levels for each
channel are reported in the corresponding meter.
The meter displays post processing and post gain levels.
