normal operation, you should not have a need to change this control.
If you find adjustment is necessary, left click on the knob and use the mouse wheel
to increase or decrease the value. Double clicking and typing a new value is disabled for
this control.
Band Coupling (Expert Control)
Each band of the five band AGC/Compressor can be offset from its neighbor
by using the Band Coupling control.
Each Band Coupling control may be adjusted over the range of 0-6dB of
decoupling (Band 1 has the option to decouple by 9dB). When all the coupling
controls are set to 0dB, only Band 2 can take on more gain (if Band 2 is the
key band, if Band 3 is the key band, that band then is the only band that can
add gain). All of the other bands will remain “flat”. Such a setting is useful in
formats such as Classical and Jazz that typically would not enjoy the automatic
spectral balance “correction” that more processed formats usually prefer.
In most programming situations the optimum setting of the Coupling controls
will likely be somewhere between -1.0dB and -3dB for bands ABOVE the key band
and -2.0dB to -6dB for bands BELOW the key band.
Decoupling the LEVELER’s
bands beyond -6dB can allow their gains to “wander” too much, causing unnatural spectral
buildup on some material. Therefore the maximum decoupling is 6dB (except for Band 1,
which can decouple to -9dB for added bass)
Normally, the EQ and iAGC settings in the preset dictate how much band coupling
should be allowed, thus Wheatstone recommends not changing this setting. If, however,
you find you NEED to adjust the band coupling, left click on the knob and use the mouse
wheel to increase or decrease the value. You can also double click on the current value
and type in the new value.
Compressor Attack (Expert Control)
The compressor attack control dictates how quickly the embedded compressor
in each band will reduce gain on “peaky” audio that is not corrected by the
slower AGC. Faster attack times will yield tighter level control at the expense
of a more dense sound. Slower attack times allow more peaky audio to pass
on to the limiter stages downstream.
As with the other controls in the expert group, the compressor attack has
been carefully set based on a number of other factors. If you find you need to
change the compressor attack, left click on the knob and use the mouse wheel
to increase or decrease the value. You can also double click on the current
value and type in the new value. The range of the control is 10mS to 1000mS (1 second).
Compressor Release (Expert Control)
The compressor release determines how quickly the embedded compressor
recovers after making a correction to the audio. Faster release times add loudness
to the audio (at the expense of more audible processing). Slower release time
allow for a smoother sound to the audio that tends to be more open.
As with the other controls in the expert group, the compressor release
control has been carefully set based on a number of other factors. If you find
