2.0 SUMMARY OF CONTROLS
This section is a brief run-down of the functions of all controls and indi-
cators to be followed in the next section by a more comprehensive set of
operating instructions. See FIG. 2.0 for reference.
2.1 POWER SWITCH
M.93 comes on with the opening of a blue eye in its push-push type power
switch. It switches both sides of the power line, consistent with good
safety practice.
Note: The REPEAT. HOLD function may occasionally be activated dur-
ing power-up disabling other M.93 functions. If the REPEAT
HOLD indicator lights, simply press the REPEAT HOLD button to
return to normal operation.
2.2 DELAY SELECTION
Each of the delay selectors, A and B, selects one of 60 possible delay set-
tings which is then displayed (in milliseconds) in the display window. If
the delay time selected is a prime value, the "prime" indicator will light.
The maximum delay for a standard M.93 occurs at the 128 msec position. How-
ever, there are seven more positions, up to 256 msec, for those machines
equipped with optional memory. When without optional memory and beyond 128
msec, an overrange indication is given by a decimal point in front of the
delay time displayed. When in the overrange condition, the actual delay is
128 msec, the maximum allowed, regardless of the longer delay setting appear-
ing in the window.
The indicated delay settings can be multiplied by factors of 2, 4, and 8 with
the DELAY MULTIPLY switch to achieve delay times up to 128 msec X 8
=
1.024
seconds (or 256 msec X 8
=
2.048 seconds for machines with optional memory).
The l, 2, 4, and 8 positions also program the system bandwidth so that the
12kHz bandwidth (available at the DELAY MULTIPLY lX position) becomes 6kHz
at the 2X position, 3kHz at the 4X position, and 1.5kHz at the 8X position.
In addition to the discrete display selection described above, one can select
any delay from a continuous sweep using the DELAY ADJUST control. It can
