Processing Parameters
25
Can help reduce multi-path when enabled. More on this in this manual.
'L-R RESTRICTION'
couples the L-R control system to the L+R control system so that the L-R gain
reduction can not increase any more than a certain dB above the L+R gain reduction. This prevents
build up of an excessive amount of stereo content. This is adjustable from 0dB to 15dB with an option
for no coupling (OFF)
'L-R INJECTION'
Sets the level of the L-R output in relation to the L+R output. This control can set
the maximum level of L-R energy in the output audio. This is adjustable from 0dB to -15dB with an
option for no L-R (OFF) which creates a mono output signal.
The
'STEREO'
menu contains the controls for the stereo mode of operation
(SHOWN IN STEREO MODE)
'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 refer-
ence level. After 10 seconds of being gated the gain reduction will return to the 0dB reference point.
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 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.
'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.
'CHANNEL COUPLING'
Couples the Left channel control system to the Right channel control system
so that the either channels gain reduction can not increase any more than a certain dB above the
other channel gain reduction, helping to preserve stereo balance. This is adjustable from 0dB to 15dB
with an option for no coupling (OFF)
The
'BYPASS'
menu contains no entries
(SHOWN IN BYPASS MODE)
The
'ENHANCE'
menu contains the low frequency enhancement filters which are used to provide bass
enhancement and help overcome the bass reduction effect of multi-band compression.
‘
DEEP BASS’
A 12dB/octave shelving bass equalizer that provides between 0 and 12dB of bass boost.
Use this control with caution as too much low frequency bass boost can cause loss of mid-bass because
the very low frequency bass, often inaudible on many receivers dominates the gain reduction of the
BAND 1 AGC and limiter. A setting of 6dB is a good compromise and starting point.
'BASS TUNE'
Adjusts multiple points in the dynamics control system, allowing you to control the 'flavour'
of the bass.
