DALPG the active version has a control circuit that removes the minimum voltage threshold and LPG work like VCA.
This device, without supplying voltage to the control input, almost does not pass the signal, when the control voltage is applied, it changes the amplitude and opens like a VCA amplifier, with a characteristic curve corresponding to the resistor optocoupler, which has a small signal release (LPG envelope), and the memory effect of a resistor optocoupler.
Technical specifications:
- Normally closed gate / VCA
- Noise transmission is dark -75db (+ - 10%) with an input signal Sine 1kHz + -5Vp-p in the mode without cutting the high frequencies.
- The maximum CV source current required for maximum opening is 3mA, operating is less than 1mA.
DALPG and DPLPG use matched pairs of opto-resistors and LEDs to provide excellent speed performance. The maximum frequency of distinguishable modulation of one signal by another signal is 10 kHz.
IMPORTANT
This is the updated version with the improved passive mode.
Size: 2hp
