Entry System / Central Office Gain Adjustment - DKS 1816 Owner's Manual

2.5 Entry System / Central Office Gain Adjustment

This section applies to 1885-010 REV S boards and higher.
These potentiometers are adjusted when more than one entry panel is attached to the 1816 system.
By default, both are set to the fully counter-clockwise (minimum gain) position and both should be left
in this position when a single entry panel is attached to the system.
ES OUT is used to adjust signal gain to the entry system lobby panel. The CO OUT is used to adjust
the gain of the signal going back to the C.O. Increasing the gain will increase the loudness.
Both should be left in the full counter-clockwise (least gain) position, unless it becomes necessary to
increase the gain (loudness) to the entry panel or out to the Central Office line. When adjusting the
gain, it may affect the echoing and may cause howling; therefore, small incremental adjustments should
be made to each potentiometer.
