SYNARE-X SENSOR ASSEMBLY MANUAL
For Board Assembly # 110116 ONLY
This vintage style synth board will give you all the great sonic possibilities of a true analog system. . Although this circuit is vintage technology compared to the digital synth world, it is still preferred by seasoned professionals for tone versatility, ease of use, and responsiveness to "on the fly" patch changes. Direct control parameters are completely step-less giving you infinite control combinations. Whether its melodic tones, or the sounds of sweeps, pops, blips, you name it...... this Percussive Synthesizer kit will provide you with an endless variety of sounds.
Construction notes:
All parts except as indicated should be mounted on the side of the PCB indicated by the silk screen.
Some components must be mounted in a particular orientation on the PCB. Follow the mounting instructions carefully and read each step completely before mounting the component.

C4, C5 3.3 uf electrolytic capacitor
D1 IN914 diode
D2 LED
Q1 2N3904 transistor
Q2 780L05 voltage regulator
U1 CA3080 transconductance op-amp
U2, U3 LM324 quad op-amp
P1, P2, P3 Solder-less Screw Terminals
NOTE: resistors R18 and R22 are no longer used in this current board design, therefore you will
not see their part designations on the board and they are no longer packaged with the kit.
Component mounting :
When soldering to the PCB, it is only necessary to apply solder to the side of the board opposite to the component being soldered. The holes on the PCB are plated through so the connection will be made on both sides.
Much time and frustration can be avoided by installing the component families on the circuit board in the order shown in the following photographs.
To avoid misplacement of a part, pay close attention the silkscreen part designators. Once the part has been soldered, it is very difficult to remove without damage to the board and/or component.

The Synare-x Inputs and Outputs:
P3 - Power Input ... 9 to 12 volts (DC only)
P2 - trigger input ... connect piezo here.
P1 - Audio output ... connect to amplifier or sound system.
P3 - Power Input ... 9 to 12 volts (DC only)
P2 - trigger input ... connect piezo here.
P1 - Audio output ... connect to amplifier or sound system.
The Synare-x Controls :
Tune - controls the pitch of the Oscillator
Freq - controls the speed/rate of the LFO wave that controls the pitch
Mod - controls the depth of the LFO wave that controls the pitch
Decay - controls the length of the sound
Sweep - controls the range in which the oscillator sweeps
Vol - controls the output volume
NOTE: The first time you power up and test the board, make sure that the trim-pot VR7 is not fully off. Trim-Pot VR7 is used to adjust the input sensitivity of the external piezo signal. Its recommended you start with it set midway on initial setup, then adjust as needed for best sensitivity response.
