1. offset is still needed to create a pulse that activates the logic circuits used by most modular synths Binary is designed for logic signals in the positive OV gt 5V range only so it can be used for conversion of S Trig signals to V Trig and vice versa without the need for the additional offset This applies to drum machines and sequencers as well as note on off events generated by or required by some analog synths OR Gate V Trig to V Trig Output is high when incoming voltage is high 5V A A A EN In the diagram above black triangles indicate the onset of an incoming 0 gt 5V signal With the OR gate active input equals output when input is high output is high This is the most common application of Binary and works with most modern devices OR Gate S Trig to S Trig Output is low when incoming voltage is low 5V A A A OY The OR gate is also used when S Trig signals should pass through without being negated S Trig outputs are normally high so the logic output of Binary will remain high when S Trig sources are patched to the inputs The output will fall when the input falls correlating to an active gate trigger from an S Trig device and signals will pass through the circuit without being negated NOR Gate V Trig to S Trig Output is low when incoming voltage is high CO 5V A A A N Things get a bit more interesting wh2. BINARY Binary is a 1 bit analog computer that takes up to six inputs and determines whether the output voltage should be high 5V or low OV Binary was designed to take the individual step outputs of a single Algorhythm module and create an additional pattern with its own controls Another application would be to combine the Pattern outputs of multiple Algorhythm modules into a single stream with the ability to mute certain portions of the sequence during playback However Binary can be used with nearly any gate trigger source Each input has its own illuminated on off switch In the ON position the switch is illuminated at approximately 50 brightness Incoming voltages will increase the brightness from this baseline providing visual feedback about the incoming signal In the OFF position the baseline is to have no illumination with an increase to approximately 50 brightness when input voltage increases The output circuitry of Binary can be switched between OR and NOR logic for different patching applications OR logic is used to combine multiple pulse inputs into a single output without changing the output voltage level With the OR gate active the output voltage of Binary is high when any of the six input voltages are high NOR is a logical negation of OR so switching to NOR logic will provide negation of input voltages With the NOR gate active the output is high by default An incoming positive voltage will cause the output

4. en you want to send V Trig signals to a device with an S Trig input To make this conversion choose the NOR gate Now the baseline output is 5V the off state of an S Trig circuit V Trig input pulses will be negated dropping the output level to OV which is the on state of an S Trig circuit When the V Trig input pulse goes low the output goes high again No offset is needed NOR Gate S Trig to V Trig tant IMA vba ine Output is nign when Inc oming voltage is low 5V A A A EN Binary can also convert S Trig signals to V Trig Patch an S Trig signals to an input and use the NOR gate Because the baseline S Trig voltage is normally high the NOR gate will negate this logic and cause the baseline output voltage of Binary to be low which is the off state of a V Trig circuit S Trig input signals will be negated and the output will remain high for as long as the S Trig input is held low No offset is needed Manual Gate Source Binary can also be used as a manual gate source Switching from OR to NOR will cause the Logic Out voltage to increase from 0 gt 5V The output voltage will remain high until the logic gate is switched back to OR For this patch the inputs would typically not be connected to anything Only the output would be used Audio Rate Experimentation Binary s fully analog design enables it to handle audio rate frequencies Try patching different waveforms from the same VC
5. incoming signals increase the illumination level to 50 to provide visual feedback about the status of muted inputs OJO O O Truth Tables Boolean logic gates can be visualized with truth tables These tables usually take two inputs and compute one output With Binary there are six possible inputs but the fundamental principle remains the same OR GATE NOR GATE Input 1 Input 2 Output Input 1 Input 2 Output 0 0 0 0 0 1 1 0 1 1 0 0 0 1 1 0 1 0 1 1 1 1 1 0 The OR Gate remains low 0 when all inputs are low and goes high 1 when at least one input is high The NOR Gate remains high when all inputs are low and goes low when at least one input is high In the truth tables above 0 represents OV and 1 represents 5V S Trig and V Trig Conversion The gate trigger inputs on most synths drum machines and sequencers are activated by a rising voltage such as 0 gt 5V This is commonly called a V Trig circuit But some devices use a different circuit called an S Trig or shorting trigger in which the circuit rests at a positive voltage and responds when the voltage drops to OV Converting between these two standards is not as simple as inverting the voltage Passing a 0 gt 5V gate signal through an inverter circuit will result in a voltage that jumps from OV to 5V when active Since most gate inputs expect a 0 gt 5V pulse an inverted gate is not generally usable as a logic signal A positive
6. to drop to OV The NOR gate can be used for sidechaining effects where a VCA or filter is closed when a timing event occurs Upbeats can also be changed to downbeats without repatching The NOR gate can also be used to convert S Trig signals into V Trig or vice versa because the output circuitry operates in the positive voltage domain only This patch is explained in detail later in the manual Binary is a fully analog design that primarily uses transistors for its logic circuitry This means that the circuitry works well into the audible frequency range Technical Details In the box Binary module Power cable 10 to 16 pin Dimensions Width 6hp 1 2 or 30mm Depth 30mm with power link cables installed Height 3U 5 06 or 128 5mm Power Requirements Maximum of 30mA at 12V Protected against reverse polarity Module Installation To install the module in your Eurorack system first ensure that power to the system is turned off Please take precautions against ESD electrostatic discharge to prevent permanent damage to the module s components Connect the smaller 10 pin socket of the power cable to the module noting the stripe indicator on the PCB which should align with the red stripe on the cable Then connect the 16 pin socket to your power distribution board Take note of the power cable s orientation with regard to the 12V supply of your power distribution board The red stripe usually b
