The DH-ADSR comes equipped with potentiometers for adjusting its attack, decay, sustain and release stages. Complementary, a delay section can be activated via a switch. It features a potentiometer for editing as well. Furthermore, the switch adds a Hold stage, which allows the user to set the length of the sustain section independently from incoming gate signals. In result, with this option active, the envelope behaves a lot like the EMS Trapezoid Generator.
While in normal operation, the DH-ADSR’s time-sensitive parameters can be set to values of up to ten seconds. For creating longer sweeps, the module offers a slow option, which switches the envelope down to 1/5th of its regular speed. Using the re-trigger function, it is possible to transform the module into a LFO.
The DH-ADSR possesses a normal and an inverted output. The latter can emit, depending on the corresponding jumper’s position on the circuit board, a signal mirrored at the 0 Volt axis (0 V to -8 V) or a biased version, which is shifted in level (0 V to +8 V).
