About this listing
Module A-150-1 (Dual VCS) contains two separate voltage-controlled switches.
Each switch has a control voltage input, a common Out / Input, and two In / Outputs. The switches are bi-directional: they can work in both directions, so can connect one input to either of two outputs, or either of two inputs to one output. Voltages in the range -12V...+12V at the O/I resp. I/O sockets can be processed by the module.
Two LEDs show which in / output is active (ie. which is connected to the common out / input).

Technical notes:
To protect the electronic switches in case of an unsuitable patch (e.g. connection of two outputs) a 1k protection resistor is inserted into the O/I line of each switch. If control voltages used for VCOs are switched this may cause a small voltage drop and lead to undesired audible detuning. For this application we recommend to insert a CV buffer between A-150-1 and the VCO(s), e.g. the modules , or the Precision Adder . Integrating the buffers into the module A-150-1 is not possible because this would ruin the bidirectionality of the switches.
Since May 2004 an improved version of the module is manufactured. The revised version allows to process voltages in the full A-100 voltage range (i.e. -12V....+12V). The previous limitation to -8...+8V is no longer valid. The new version can be distinguished from the previous version by the printing at the pcb ("A-150 DUAL VC SWITCH VERSION 2"). Another way to distinguish the two versions are the integrated circuits: "CD4053" for the old version, "DG409" for the new version. Sorry it is not possible to update the old version of the A-150 to the new one as the complete circuit has been changed.
Remark: Module A-150 has been renamed to A-150-1 to distinguish it better from other modules of the A-150 series (e.g. )
