being separated by a 2-second pause.
Each sequence provides tones for check-
ing frequency response, as well as left/
right channel identifiers. Configuration DIP
switch 5 is used to select whether the
basic or advanced multi-tone sequence
will be generated. Refer to Appendices
A-1 and A-2 for detailed descriptions of
the multi-tone sequences.
Multiple Play Functions
When more than one play button is se-
lected, a different set of rules apply. If the
voice button is selected, along with the
single tone and/or multi-tone button(s),
the voice sequence of L+R, L ONLY, and
R ONLY will play once, a 2-second pause
will occur, and then the next selected
function will become active.
If the single tone button has been se-
lected, along with the voice and/or multi-
tone button(s), a 400Hz or 1kHz tone will
be generated for 15 seconds, a 2-second
pause will occur, and then the next func-
tion will become active.
If the multi-tone button has been selected,
along with the voice and/or single tone
button(s), one complete basic or ad-
vanced multi-tone sequence will be gener-
ated, and then, after a 2-second pause,
the next function will become active. To
know which function is active is simply
a matter of observing the play LED
indicators.
Master Output
The Model 750’s master output section
contains a variety of buttons and controls
associated with the main and AUX audio
buses.

AUX and Main Master Level Controls
Two controls are used to set the overall
level of the AUX audio bus. The inner knob
controls the level of the left channel; the
outer knob controls the right channel. On
the front panel, note the small arrow
graphic symbol and the letter “U,” located
at the “1-o’clock” rotation position. This
indicates the approximate setting for the
level controls to give unity gain, and is the
position where the controls should nor-
mally be set.
