Dual Trigger Delay A-162

1. Introduction

Module A-162 (Dual Trigger Delay) contains two

separate delay circuits for trigger signals.

This module makes it possible to delay the onset of a

trigger pulse, and also change its length (see Fig. 1 on

page 3).

On each of the trigger delays, two controls can alter

the onset time and duration of triggers, from 0 up to

round about ten seconds. A control LED indicates the

onset and duration of the new trigger.

User examples Modulation delay The A-162 is particularly useful for delaying the onset of modulation, for instance of a VCF, VCO, VCA, etc., by causing the gate to open later. It can also create pseudo echo effects. Gate VCA 1 VCO CV doepfer VCA. By patching in an AR envelope (in this case an A-170, but an A-140 could also do the job) the intensity of the vibrato can increase and decrease gradually. Stereo "Echo" The patch in Fig.
