Doepfer A-150-8, Octal Voltage Controlled Switch, Eight manual or CV controllable switches, Shared output / input (O / I) and two inputs / outputs (I / O1, I / O2) per switch, Functions of inputs and outputs are interchangeable, Two modes: toggle or level, Possible to chain multiple channels from the master / slave function, Width: 12 HP, Depth: 55 mm, Power requirement: +40 mA (+12 V) / -5 mA (-12 V)@+*Note:* A protective resistor in each O / I line can cause voltage drops when transmitting CV voltages. When transferring pitch control signals to a VCO, it is therefore advisable to insert a CV buffer (e.g. Art.#378330#, not included).
