Processing Parameters
24
The 'L+R' menu contains the controls for the L+R (SUM) section of the matrix mode of operation
.
'IDR Sets the range in dB of the window gating system. The processing will turn off while the
audio is inside this window. The window can be set between 1 and 15dB.
'GATE' The gate function prevents 'suck-up' of noise during periods of silence or low level audio.
The level can be adjusted to turn on when the input drops to a level from -15dB to -35dB below
the reference level. After 10 seconds of being gated the gain reduction will return to the 0dB refer-
ence point.
'B1 RELEASE' Controls the release/decay rate of band 1 of the AGC, the time the AGC takes
to respond to a decrease of input level. The DECAY time can be varied between 1 and 10 with
smaller numbers indicating faster release times.
'B2 RELEASE' Controls the release/decay rate of band 2 of the AGC, the time the AGC takes
to respond to a decrease of input level. The DECAY time can be varied between 1 and 10 with
smaller numbers indicating faster release times.
'B3 RELEASE' Controls the release/decay rate of band 3 of the AGC, the time the AGC takes
to respond to a decrease of input level. The DECAY time can be varied between 1 and 10 with
smaller numbers indicating faster release times.
'B4 RELEASE' Controls the release/decay rate of band 4 of the AGC, the time the AGC takes
to respond to a decrease of input level. The DECAY time can be varied between 1 and 10 with
smaller numbers indicating faster release times.
The 'L-R' menu contains the controls for the L-R (difference) section of the matrix mode of operation
'IDR Sets the range in dB of the window gating system. The processing will turn off while the
audio is inside this window. The window can be set between 1 and 15dB.
'GATE' The gate function prevents 'suck-up' of noise during periods of silence or low level audio.
The level can be adjusted to turn on when the input drops to a level from -15dB to -35dB below
the reference level. After 10 seconds of being gated the gain reduction will return to the 0dB refer-
ence point.
'B1 RELEASE'
Controls the release/decay rate of band 1 of the AGC, the time the AGC takes
to respond to a decrease of input level. The DECAY time can be varied between 1 and 10 with
smaller numbers indicating faster release times.
'B2 RELEASE' Controls the release/decay rate of band 2 of the AGC, the time the AGC takes
to respond to a decrease of input level. The DECAY time can be varied between 1 and 10 with
smaller numbers indicating faster release times.
'B3 RELEASE' Controls the release/decay rate of band 3 of the AGC, the time the AGC takes
to respond to a decrease of input level. The DECAY time can be varied between 1 and 10 with
smaller numbers indicating faster release times.
'B4 RELEASE' Controls the release/decay rate of band 4 of the AGC, the time the AGC takes
to respond to a decrease of input level. The DECAY time can be varied between 1 and 10 with
smaller numbers indicating faster release times.
ATTACK Controls the attack rate of the Ariane AGC, the time the AGC takes to respond to an
increase of input level. The ATTACK time can be varied between 1 and 10 with smaller numbers indi-
cating faster attack time.
'B1<B2 COUPLING' Sets the amount of coupling between the band 2 gain reduction system and
the band 1 gain reduction system. This is adjustable from 0dB to 15dB with an option for no coupling
(OFF) This coupling is uni-directional, band 2 into 1.
'B3<B4 COUPLING' Sets the amount of coupling between the band 3 gain reduction system and
the band 4 gain reduction system. This is adjustable from 0dB to 15dB with an option for no coupling
(OFF) This coupling is uni-directional, band 3 into 4.
'B1 L-R MUTE' Mutes the output from the B1 L-R processing stage. This can be set to ON or OFF.
