Model 750

The five choices are main output left, main output right, AUX output left, AUX output right, and mic/line direct:

•Main output left and main output right are the same signals that connect to the output circuitry associated with the main outputs.

•AUX output left and AUX output right are the same signals that connect to the output circuitry associated with the AUX line-level output.

•Mic/line direct is a signal that is derived from its associated mic/line input chan- nel. The signal is the same as that connected to the pan-pot; post input preamplifier, low-cut filter, and phase reverse function. Configurable output 1 has access to the signal from mic/line input 1; configurable output 2 has access to the signal from mic/line input 2; etc.

Using the five DIP switches associated with each configurable output, simply select the source or sources desired. Note the word “sources”—more than one source can be selected! As an example, selecting switch 3, AUX out left, and switch 4, AUX out right, will produce a monaural (L+R) version of the AUX output. Selecting switch 1, main out left, for configurable output 1, and switch 2, main out right, for configurable output 2 will result in another stereo output, viola, main output 4!

It would be the author’s choice to use the configurable outputs in this way: Configurable output 1 set for a mono version of the main output, configurable output 2 set for a mono version of AUX output, and configurable outputs 3 and 4

set for mic/line direct outputs. Terminating on the patch bay, these four outputs could provide quite handy for those “once in a blue moon” situations that seem to occur about once a month!

The two mic/line direct outputs may prove especially helpful, providing two channels of “mic/line amplifier” for general purpose or emergency use. In special situations, a signal of virtually any audio level could be “bumped” to nominal +4dBu.
