Behringer MDX 2200 Composer Pro+
Live Performance Bass Settings.
Daisy Chain both halves of the Stereo Compressor by patching channel one output into channel two input.
Bass>Preamp>Channel 1 Input>Channel 1 Output>Channel 2 Input>Channel 2 Output>Amp
Both Channels:
Expander Gate (both pots set to "12 noon"): Threshold: -35, Ratio 2.5, Release: Slow
Interactive: ON
SC Filter: ON
Auto: OFF
I/O Meters set to: OUTPUT
Channel 1:
Threshold approx. -6.5 db, ("12:30")
Ratio: 4:1
Attack: 30 ms]
Release: A little faster then ¼ second, i.e., 0.25. "9:30"
Output: Boost +3db, ("2:00")
Set Peak Limiter to where it barely flashes on your strongest open E slap.
{suggestion @+12, "12:30"}
O.K., these seem like reasonable compressor settings.
The magic is in the second channel that maintains dynamics
and raises the headroom thus making the amp louder.
The trick is just "re-compressing" the peaks only.
Therefore the noise floor does not go up and
the remaining high energy peaks are tamed, not limited,
for more headroom without over compressing the dynamic signal.
Channel 2:
Threshold: approx. +6.5 ("2:30")
This Threshold setting allows Channel 1 to duck under this setting
and therefore only the peaks are processed by Channel 2.
Ratio: 4:1
Attack: Fastest Setting (1 ms)
Fast Attack times cause "click."
This phenomenon is eliminated by the Attack setting on the Channel 1,
and the Channel 2 Threshold also protects against click.
A very fast Attack is necessary on Channel 2 in order to have the Peaks
acted on a fast as possible, thus extending headroom.
Release: A touch above 0.25 ms. ("10:30")
Output: ("1:30")
Peak Limiter: to taste...
Or the slightest flash with the the hardest slap on open E
{suggestion @ set at +16 db.}
