Resistance (Pin 6): ΩkΩ Delay Time (ms): Internal Clock Frequency (MHz): THD (%): Solve for: ResistanceDelay Time Calculate Using the PT2399 Calculator The PT2399 Echo Processor chip allows you to adjust the delay time via a simple resistor across pin 6 and ground. This calculator allows you to calculate the delay time from a resistance, … Continue reading PT2399 Calculator
