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 arent found on
other audio mixers. Their uniqueness may
make them seem a bit confusing at first
glance. However, they arent 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.
