Each channel of the A-150-8 features a push-button and a CV input for controlling the built-in switch. Furthermore, there are three connectors per channel (O/I, I/O 1, I/O 2). Two basic types of usage can be distinguished:
- One signal is fed to the channel via the O/I socket. Depending on the switching state, signals are routed to either I/O 1 or I/O 2.
- Two signals are fed to the channel via the connectors I/O 1 and I/O 2. Depending on the switching state, one or the other signal is routed to the O/I socket.
Users can choose between two modes of operation:
Toggle mode: The state of the switch is changed by pressing the push-button or a rising edge at the CV input.
Level mode: The state of the switch is changed by the level of incoming control voltages (< +1.5 V = I/O 1; > +3.5 V = I/O 2). The push-button works differently in this mode as well: As long as the button is pressed, I/O 2 is used. If the button is not pressed, I/O 1 is used.)
Several channels can be linked via master / slave groups.
Please note: The O/I lines feature protection resistors. This can lead to small voltage drops, which in most cases can be neglected. Exception: Pitch control voltages for oscillators. If you experience any problems, please us an active multiple like the A-180-3 as a buffer circuit.
