info RACKMOUNT EFFECT
Main panel features a simple 7-segments LED display, a LED peak meter, 2 knobs and 18 buttons.

Terminal connectors:
- Midi interface
- modulation CV tension input
- 3 footswitch inputs (bypass, modulation and hold)
- delay out (-20/+4 dB)
- mix out (-20 / +4dB)
- input signal (-20 / +4dB)
- XLR I/O
- headphones (frontal).


 


edit
SYSTEM based on 8-bit CMOS micro processing unit HD6303 family.
The D-1500 is a Monophonic delay unit, max time 1 seconds (1023 miliseconds to be precise) range frequency response from 20 Hz to 18 kHz with adjustable phase (a 180 degrees phase shift).


hold

 


edit FUNCTIONS
the delay can be changed using 3 parameters:
- FEEDBACK sets the amount of repeated echoes
- MIX is the balacing between dry and wet
- TIME is displayed on the LCD.

hold

 


edit TIME
special HOLD function freezes the sound during 1 second cycling the signal.

 

hold



edit LFO single digital oscillator (shape: sine or square) modulates the delay pitch with variable depth. and frequency range from 0,1 to 15 Hz.
CV the tension controls the internal LFO rate: relative voltage range from 0 to 10 V.


LFO modulation



edit FILTER a basic low pass filter for the generated delay at 1 pole.
There are only 6 fixed cutoff values : 2,5/ 4 / 6 / 8 / 10 / 20 kHz.


15 hz





edit
MIDI Early Midi implementation: really limited and quite useless as it manages only the program change.


 


edit MAINTENANCE
not much to say, quite reliable unit .
Reported missing segment on displays.
Latest and only OS -seems- to be V.1.0.



CPU+ EPROM V1.0

 



edit
MEMORY:
- 1 s. max sampling time.
- 16 patches setups.
Memory system works with a soldered 3V Cr-2032 lithium battery, replacement needs some basic skills.
