Model 750

The Model 750 uses an IEC standard connector to mate with the AC mains cord. Normally the cord supplied has a North- American standard plug on one end and an IEC connector on the other. In non- North American applications the appropri- ate plug must be attached. The wire colors in the mains cord will, in most cases, conform to the internationally recognized CEE color code and should be wired accordingly:

Connection

Wire Color

Neutral (N)

Light Blue

Live (L)

Brown

Earth/Ground (E)

Green/Yellow

Because the Model 750 contains no power switch it will start operating as soon as AC mains power is connected.

Configuration

As in life, power leads to responsibility. The Model 750 is no exception as its features, flexibility, and operational power leads to a number of configuration issues that must be reviewed once installation has been completed. All are quite simple and, with the exception of the front panel configuration DIP switches, will only need to be addressed once.

Configurable Outputs

The Model 750 contains four configurable outputs, the likes of which aren’t found on other audio mixers. Their uniqueness may make them seem a bit confusing at first glance. However, they aren’t too weird, simply being electronically-balanced output circuits whose input source is selectable, rather than being fixed. The hardest part of using the configurable

outputs is deciding which audio source, or sources, should be assigned to which output! By carefully reviewing the choices, and how their selection may benefit an installation, the power of this humble out- put should become apparent. These four outputs may well eliminate the need for external distribution amplifiers, combining amplifiers, and microphone preamplifiers.
