VI. Clip/OL
In light of the internal routing complexities and the considerable amounts of gain
available in both the EQ and Dynamics sections of the Model 2020 High Resolution
Discrete Input Channel, the Clip/OL LED indicator provides an essential metering
function. This peak detection meter monitors both the EQ and Dynamics outputs to
warn of signal overload, regardless of the routing option selected on the Routing control.
It should be noted that although this warning LED is triggered at 24dBu from either
aforementioned output, actual clipping throughout the Model 2020 is not experienced
until approximately 26.8dBu, thanks to the extended headroom of GML 9202 discrete
opamps.

VII. Control Link
The Link function of the Model 2020 provides a unique means of connecting multiple
units together via the RCA connector on the back panel of the unit. The link signal is
always present at both connectors, but only affects the normal Dynamics operation
when the Link switch is engaged. It is paramount to remember that in this mode of
operation, signal peaks in any channel will affect all channels linked with that unit.

always present at both connectors, but only affects the normal Dynamics operation
when the Link switch is engaged. It is paramount to remember that in this mode of
operation, signal peaks in any channel will affect all channels linked with that unit.
Engaging the Link switch in the Dynamics section allows the control path to continue
converting the incoming signal (regardless of control path input source) as in normal
operation, but each Dynamics section's resultant logarithmic control signal will affect the
other's operation. Thus, signal peaks in either channel will affect both channels for
linked operation. This feature allows the Dynamics sections of multiple Model 2020's as
well as Model 8900's to interact.

Activating the Link switch affects the GML 2020 Dynamics section in a much different
manner than traditional stereo couple or link switches in most conventional dynamic
range devices. The control signals are combined in such a manner as to leave all of the
various conversion, detection, and comparison circuits intact and operational in all
channels simultaneously. Other dynamic control units have a predilection to merely use
the control signal generated by one channel in deference to the other channel’s
complete control path, thus obviating the second control path. This inferior method
renders the resultant dynamic control insensitive and impervious to the second
channel’s unique dynamic content and unresponsive to desired dynamic content
differences between channels. It is important to remember that in order to achieve
identical dynamic range control characteristics for both channels, the Threshold, Output,
and Ratio front panel controls must be adjusted accordingly since these controls still
affect the actions of the Knee circuit, which follows the control link signal tap.
