SAMARA utility waveform processor ii operator’s manual rev. 1962/2.
module explained SALUT MODULE OVERVIEW Thank you for purchasing this Xaoc Devices Samara features four channels—each with product. Samara II [saˈmara] is both a flexi- two inputs and an attenuator, plus two ad- ble mixer and a multifunction utility that may ditional switchable (+5V/-5V) offset gener- be used for processing audio signals, control ators, four voltage level and polarity indica- voltages, and modulation waveforms.

Three input signals from channels 2, 3 and 4 are scanned (or selected) by the voltage in channel 1 (fig. 4).
