R/C Manual

1. R/C OVERVIEW

 

 

A CONSTELLATION refers to the whole array of preamps attached to the same LAN. It may comprise only one 1788A or up to 128 of them. Preamps may be assigned NET numbers placing them in different banks even when any given bank is not filled. For example, you could have up to 16 preamps all within one bank, or assign them variously to as many as 8 banks. At the other extreme, you could have 128 preamps that occupy 8 fully filled banks. That’s a damned lot of channels (1024).

1.4 HARDWARE R/C

Aphex manufactures a dedicated companion controller unit, the 1788A-R. Each 1788A-R can control a bank of up to sixteen 1788A’s (equalling 128 microphone channels). Each 1788A-R has MIDI In and Through ports that can be used to extend remote control to MIDI control devices which will be directed through the 1788A-R to the targeted 1788A’s. Communications between 1788A-R’s and 1788A’s is exclusively by LAN.

NOTE: One 1788A-R can control one of eight assignable banks. Up to eight 1788A- R’s can be used to control up to eight banks of 1788A’s.

Direct selection of any 1788A within a bank gives rapid access to all functions through a control surface that exactly matches the front panel of a 1788A including Group Select and Test Tones. The 1788A-R also supports Preset Store and Preset Recall within its bank. Remote control action as well as preset change propagation is fast and reliable.

1.5 COMPUTER R/C

Software developed especially for the 1788A is available for both PC and Mac platforms. Using a friendly GUI (Graphic User Interface) the software program makes monitoring, controlling and automating multiple 1788A’s easier in many ways. It is certainly more economical than using multiple 1788A-R’s for large installations.
