Sometimes, depending on when the remote controller and preamplifiers received their IP addresses, it may be necessary to use the Wake-up function to get the controller attached to all preamps in its bank and clear all red lights. This is a good practice just to assure full synchronization of the constellation some time after all units have been powered up.

NOTE: Avoid giving more than one 1788A the same NET number. It will cause network errors and unpredictable results.

3.7.4 Coexisting with a Software R/C

One PC or Mac computer running Aphex 1788A R/C software can operate in concert with up to eight 1788A-R’s. Read Section 5 to learn about using the software controller.

3.8 MULTIPLE SELECT GROUP BEHAVIOR

When using Multiple Select to create a group, you will pass certain characteristics to the controls.

1.All on/off functions will synchronize and follow the control of any individual in the group. For example, you switch on the PAD of any one channel in the group and all other PAD’s will also switch on. Any function not deliberately operated will remain in the original state of member mic channels, however. To make all grouped channels the same, you need to operate all the on/off controls.

2.Input, Aux, and Main Gain values will remain Relative. Even if you top or bottom out all the controls, an overscale memory will retain their original relative difference and when you bring the gains back out of limits, they will regain their relative values. This is good for maintaining a deliberate mic balance while nudging them all up or down a certain amount. This characteristic is identical to the Local Control characteristics that are covered in the 1788A Owner’s Manual.

3.Input, Aux and Main Gain can be group equalized to limits by first Multiple Selecting a group, running their gains to the upper or lower limit, and turning Multiple Select button off and on again. Now the overscale memory is erased, and all controls will track at the same gain as any one of the group that is adjusted.
