More CLARITY
We can obtain extra clarity and quality in several ways.
Ariane AGC:
Slow down the release times.
Increase the IDR settings letting the release come into play less often.
Decrease the GATE thresholds allowing the release times to release less often.
Increase the band and channel coupling ratios , letting each bands energy be restricted by its neighbour.
Multi-band Limiters:
Speed up the peak attack times, letting less through to the clippers.
Slow down the release times of the average release time constants.
Speed up the average attack time so that the average time constants dominate the control signal providing
slower control.
Increase the HOLD level (lower thresholds) .
Increase the DELAY times.
Decrease the limiter thresholds, letting less through to the clippers.
Increase the band and channel coupling ratios, preserving the spectral and channel balance of the original
program material.
Final clippers: (FM USE)
Decrease the multi-band clipper drive
Possibly switch the bass clipper to soft mode
Lower the bass, mid and HF clip levels to prevent less distortion in the final clipper while carefully listening for
distortion generated in the multi-band clipper.
Decrease the final clipper drive
Increase the clipper finesse control
Look-ahead limiter: (DRUSE)
Decrease the look-ahead limiter drive.
Decrease the attack time constants, speeding up the attack of the secondary time constant circuits.
Increase the decay time constants, slowing down the decay of the secondary time constant circuit.
Adjust the shelf control to obtain the most suitable HF balance.
WE SUGGEST ONLY SMALL MODIFICATIONS FROM FACTORY PRESET SETTINGS IF YOU ARE

More BASS
We can obtain more bass in several ways.
Bass Enhancement:
Increase the shelving filters gain. Listen carefully when adjusting because you can cause suck out of the mid
and upper bass by excessive low frequency boost.
Increase the peaking filters gain.
Decrease the peaking filter Q factor.
Sometimes more AUDIBLE bass can be achieved through more peaking gain and less shelving gain as the
peaking filter operates in the region where the ear is more sensitive. Lots of shelving gain can rob the loud-
ness in this ear sensitive region by the gain being reduced by the less audible low frequency material that
may have more level, controlling the gain reduction of the band 1 AGC and limiter.
Ariane AGC:
Speed up the band 1 release.
Reduce the IDR setting.
Reduce the band 2 to 1 coupling control, letting band 1 increase its gain more often.
