LushOne system technical specifications
|Module size||LushOne modules are designed as single circuit boards which carry all electronics, connectors and controls. The board size is:
5.675" (144.145mm) x 2.95" (74.93mm).
|Mounting holes||Mounting holes are inset horizontally and vertically 0.15" (3.81mm) from each corner.
Holes are diameter 0.12" (3.05mm).
|Signal connectors||Signal connectors are 2mm banana sockets mounted on the board. Suitable connectors are Rapid Electronics "2mm Economical PCB Socket" (code 17-1042).|
|Power connectors||Power is connected via solder terminations that should be located at the edge of the board near the lower-left corner.|
|Power supply voltage||Power supply is nominal +9V and -9V, but the LushOne may be battery operated and modules should tolerate reasonable variations on this level|
|Power supply current||Approximate values (positive, negative):
LushOne Base: 70mA, 40mA
LushOne Contour: 30mA, 20mA
LushOne Inca: 30mA, 25mA
LushOne Echo: 60mA, 35mA
|Signal voltage||Audio signals are at nominally +1V/-1V peak.|
|Control voltage||Standard control voltage is 0V to +5V. Most, but not all, control voltage inputs will tolerate voltages outside this range.
Control voltage to frequency ratio is uncalibrated. The "Log F" control voltage output on the LushOne Base and operates at about 0.65V/octave.
|Base Oscillator Waveforms||Saw, Square, Sine, Triangle, Ramp
Triangle/Square Combo, Rectangle (Medium mark-space ratio), Rectangle (High mark-space ratio) (Version 2 only)
