A quick reference to these basic functions is found in this manual’s Section 1.2 -The 1788-R Remote Controller at a Glance.
2.0 FUNCTIONS 2.3 PRESET HANDLING BLOCK In applications using multiple Model 1788’s, such as theater and live concerts, it is critical that mic preamp settings can be stored and changed quickly as Presets. The Model 1788-R is a state-of the-art solution that not only duplicates the key functions of the Model 1788 but provides a means to quickly recall a series of settings that are used in every performance.

This means that a preset can be selected and modified using the Local Block without actually transmitting the changes to the selected unit. This makes it possible to change settings for an upcoming preset, for example the next preset used in a live show, without interfering with the current settings of the connected Model 1788s.

The audio industry has accepted for years the necessity of running microphone lines from the microphone back to the mix position. Once at the mixing console (or dedicated microphone preamp) the microphone levels are amplified to line levels.
