Overview
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 (front)
System
Monophonic delay unit range response from 20 HZ to 18 kHz with adjustable phase (180 degrees shift)
Time
up to 1 seconds (1023 miliseconds) special HOLD function freezes the sound during 1 second cycling the signal.
Functions
the delay can be changed using the following parameters:
- FEEDBACK sets the amount of repeated echoes
- MIX is the balacing between dry and wet
- TIME is displayed on the LCD
LFO
single digital oscillator (frequency range 0,1 to 15 Hz) modulates the delay pitch with variable depth.
There is two LFo shapes: sine and square.
Filter
a basic low pass filter for the generated delay at 1 pole.
There are only 6 preset cutoff values : 2.5/ 4 / 6 / 8 / 10 / 20 kHz
Midi
Early Midi implementation: really limited and quite useless, in fact in manages only the program change.
CV
the tension controls the internal LFO rate, relative voltage range is from 0 to 10 V.
Memory
- 1 s. max sampling time.
- 6 rom presets
- 16 patches setups.
Review
OK: affordable / intuitive / oldschool
NOT : monophonic / limited Midi
"This were great units at the time, but digital delays are quickly getting old especially monophonic ones. Anyway if you are looking for a solid delay with character, the D1500 could be your dream machine."
