Maximum delay for the Super Prime Time is 640 mS (standard) or 1.28 
sec (with memory expansion) at X1 clock rate and 960 mS or 1.92 sec 
at X1.5 clock settings. I don't know if there was ever any 
aftermarket memory expansion that allowed longer delays.

There is a single delay line with two taps. Each delay tap has its 
own feedback control and its own level control for the main output 
mix. Separate audio outputs are available for Delay A, Delay B, Inpur 
mix, and Master mix out.

The modulation LFO has a frequency range from 0.05 Hz to 500 Hz and a 
3:1 sweep of the delay time. The modulation waveshape is selectable 
as either sine or square wave, and may be be continuously varied 
between either of these and an envelope follower that tracks the 
input signal. Both delay sweep and LFO rate may be controlled with 
external foot pedals and the LFO section has both signal output and 

The unit was pre-MIDI so it doesn't accept program change commands, 
but it does have its own system for program storage and retrieval 
that can be address with an external foot switch.   There are 8 
factory programs in ROM and 32 user registers in nonvolitile RAM.

The front panel controls include a nice set of linear faders grouped 
as an input mixer (main input, aux input, feedback A, feedback B, low 
pass filter) and an output mixer (main input, aux input, delay A, 
delay B, master output). The unit is 3U high, giving plenty of space 
for these controls. There are also four rotary pots for LFO 
modulation (manual sweep, depth, waveshape, rate) and two knobs to 
set the delay taps.
