The 12V rail consumes 8mA of current REAR PANEL CONNECTIONS The HLFO module PCB contains additional inputs and outputs allowing for bussing signals between modules from the rear panel This can be useful for normalizing modules in a rack or creating auxilliary inputs and outputs J10 connections are as follows Pin 1 Force sensor output 0 to 5V Pin 2 CLK Out 10V to 10V Pin 3 Sample hold output 5V to...

Page 4: ...MPER J1 The HLFO produces the default S H waveform by sampling the module s internal noise source The S H input signal can be normalized to an external signal instead To do this the external signal must be connected to J10 pin 5 S H EXT INPUT and J11 pins 2 3 must be jumpered For normal operation jump J11 pins 1 2 FSR FAST SLOW MIN RATE C3 C12 C16 C17 C25 C26 C27 C28 C29 C30 C31 C32 C33 D2 D6 D8 D...
