1.0 INTRODUCTION AND INSTALLATION
1.1 INTRODUCTION
The PRIME TIME Model 93 is a sophisticated digital delay system incorporating
a high performance delay 1 ine, specia 1 effects capabilities, an·d versati 1 e
mixing functions. The heart of M.93, its digital delay circuitry, is the
very same as that of our professional DELTA-T series• Model 92 with one im-
portant exception: there•s more delay -- twice as much, over
~
second, at
the full bandwidth and up to 16 times as much, over 2 seconds, at reduced
bandwidth (utilizing an optional memory extension).
For special effects M.93 incorporates a delay time modulator (VCO), feedback
equalization, phase inversion, a repeat-hold function (for unlimited repeti-
tion without degradation) and more. Multiple inputs and outputs and indepen-
dent four-function input and output mixers make M.93 an extraordinarily flex-
ible instrument. M.93 is capable of reverberation enhancement or distant
echoing, of flanging or doppler pitch shifting, of musical vibrato or dis-
cordant resonance -- of nearly anything that can be done with time delay.
1.2 UNPACKING AND INSPECTION
Remove M.93 from the packing material taking care to avoid breaking or bend-
ing any of the many switches, levers, and knobs. Thoroughly inspect both
the unit and packing carton for indications of shipping damage and report any
damage found to the carrier. If in good condition, be sure to save the car-
ton and packing materials in the event it becomes necessary to reship the
machine.
1.3 INSTALLATION
M.93 is designed to be rack mounted in a standard 19 inch relay rack (unit
dimensions: 3~ 11 H X 12
11
D), but it can also be rested on a flat surface. If
the unit is to be shipped while rack mounted, it may be desirable to support
the rear of the chassis to protect it from mechanical shock. Be sure to
leave ventilation space around the top and bottom covers since electronic
equipment lasts longer and is more reliable if kept cool~
1.4 POWER REQUIREMENTS
M.93 can be operated from either 115 or 230 volts at 50 or 60 Hz, provided
