function as an Insert FX Bus, with 3 PAUs all its own. So if you run into trouble with PAUs on
the Insert FX buses and can sacriÞce a global effect, this is one solution.
Metering
KDFX has two kinds of metering: arrow meters and bar-graph meters.
Arrow meters
All Input and FXBus pages have rudimentary signal meters, as weÕve seen. On the Input pages,
the arrow next to the input letter ßashes when there is signal present at the input. On the Insert
and Aux FXBus pages, the arrow next to the FXBus number ßashes as long as there is signal
being processedÑin effect, itÕs an output meter. The arrows ßash whenever the signal level
exceeds 14 bits below full scale, which is -84 dB relative to the maximum level the KDFX can
handle. Since typically the K2500 is operated with about 20 dB of headroom, this translates to
about -64 dB relative to normal operating level
.
Bar-graph meters
In addition, a number of KDFX Algorithms include a fast visual metering system for
monitoring what the Algorithms are doing. Many of these Algorithms deal with dynamics
control like compression and limiting. An example is Algorithm 950, HardKneeCompress.
Meters are most often found on the
PARAM2
page of the FXPreset Editor:
In this Algorithm, the meter is showing the gain reduction that the compressor imposes on the
signal coming into it.
Metering is also used for other purposes in some other Algorithms, for example 902 LFO Sweep
Filter. In this Algorithm, the meters show the current center frequency of the left and right
Þlters as they sweep up and down the spectrum:
Meters use up a certain amount of KDFXÕs processing power, although less than a whole PAU,
and so they are only used only in Algorithms where they are particularly appropriate.
