In stereo linked operation, the input and output meters double up, left above
right. When more than two channels are linked, the top meter corresponds to
the current channel selected and the bottom meter corresponds to the channel
to its right.
The GainBall and RMS
vs. Peak Detectors
A red dot will light to the right of the output level meter when the Soft Clip
circuit threshold is crossed.
The vertical gain reduction meter along the right side of the GainCurve graph
shows dynamic gain variation. Note that this meter is not influenced by
adjustments to input level or makeup gain, its purpose is to show how the gain
is changing over time. Absolute gain, which includes makeup gain, can be
determined by looking at the dB numbers along the vertical axis of the graph.
A single channel in the ES108A can perform two separate dynamics pro-
cesses, such as gate and compressor, simultaneously. In some cases these
different processes will use different detector algorithms to sense the level of
the side chain signal. Two types of algorithms are possible: RMS or Peak.
Recall that the GainBall’s horizontal deflection follows the side chain signal
level. Because the RMS and Peak levels of the side chain signal are not
generally the same, the GainBall must choose which one to follow. To address
this situation, Euphonix has adopted the following convention: When a Peak-
driven processor (gate or peak limiter) is adjusted, the GainBall follows the
Peak level of the side chain signal. When an RMS-driven processor (compres-
sor, expander, or ducker) is adjusted, the GainBall follows the RMS level.
Because the GainCurve can show a combination of two processes on the same
curve, it is possible for the GainBall to land “off the curve”. For example, if a
+10dB steady sine wave is present in the side chain and a gate parameter was
most recently adjusted, the GainBall will sit 3dB to the right of the compressor
curve. When adjusting parameters which do not directly control a dynamics
process (such as Bypass or Side Chain Listen), the GainBall keeps following
the detector of the process most recently adjusted.
