Head Out- Eurorack Headphone Amp & Output Module The Head Out module has stereo line level outputs and a stereo headphone output. The line level L and R outputs have attenuators, and are intended to accommodate hifi/pro audio equipment. The headphone output utilizes a 2164 VCA-based circuit, allowing for plenty of volume. The headphone circuit operates independently of the line level circuit, so all outputs can be used simultaneously. Features: L and R input (L input normals to R input) L and R line level outputs with attenuators Attenuation trimmer (to set max output of st ..read more

BUY HERE The Synthrotek VCA is the latest in our popular Eurorack slider series. The LEDs of the bleed and level pots brighten and dim according to the incoming voltage. A linear/exponential selector switch is located on the rear of the module. Features: Bleed and level control per channel Linear and exponential settings Audio channel 2 is normalled to channel 1 Specifications: DC coupled Module Width: 4HP Module depth: 22mm Current draw: +12V: 40mA -12V: 40mA The post VCA Module first appeared on Synthrotek ..read more

BUY HERE Now with banana jacks for power monitoring! The TS2 builds off the TST module. You still have a 16-pin power header on the front of the panel for testing modules, but we’ve added banana jacks for each power rail and for ground to make it easy to quickly check your voltage levels with an oscilloscope or multimeter. The ground jack can also be used to share a ground when patching Eurorack and Buchla system together. A 16-pin plug is included to shield the header power pins when the module is not in use.   Please note: Use this module at your own risk. You will be exposing electri ..read more

BUY HERE Synthrotek’s Super Power 2 gives you loads of power and is skiffable at just 46mm deep! Designed with safety in mind, Super Power has reverse polarity protection and converters with short circuit, overheating, and over current protection. The Super Power 2 now gives you the ability to set your power voltages precisely to +12V and -12V, which is critical for 1 v/o applications, oscillator tuning, and dialing in voltages between systems. On any power supply, your power voltages will change slightly as modules are added or removed from your system; now you can adjust your voltages q ..read more

BUY HERE The CF is a passive crossfader module. It does not have bleed at the extremes like other passive crossfaders. It is ideal for attenuating, mixing or crossfading audio signals (not as ideal for precision voltages). The max amplitude output will be about half the strength of the original signal. If you’re using unbuffered audio sources, there can be a slight dip in amplitude at the extremes. Specifications: Module width: 2HP Module depth: 14mm Current draw: none The post “CF” Crossfader Module Released first appeared on Synthrotek ..read more

BUY HERE The XFD is a CV-controlled vactrol-based crossfader module, ideal for both audio and bipolar CV sources. It can be used as a cv-controlled attenuator: connecting just one input allows the signal to quickly fade in a VCA-like fashion. Works with video synths! Selecting the video version and we will send high-speed op amps in place of TL072 ICs. (If you purchase the audio version, you can change it to video down the road by swapping the ICs and soldering in a few ceramic caps.) Specifications: Module width: 3HP Module depth: 37mm Current draw: +12V: 15mA, -12V: 15mA The post XFD Mod ..read more

BUY THE MODULE HERE! The Five Amp is a throwback to our original 5A Power Supply with some upgrades. It uses a quality 12V brick for the +12V power regulation instead of a +12V converter. The plus side of doing it this way is that whatever amperage the -12V and +5V rails are not using can be used by the +12V rail, which always draws the most of the three. Five Amp comes in three different power configurations. We recommend selecting an option based upon your -12V rail draw. For a rule of thumb, Red (with red LEDs) will power a single row of 84 or 104HP, Green will power two rows of 104HP ..read more

CLICK HERE TO BUY THE MODULE The VidPix makes all your 8bit video dreams come true! It uses incoming audio to change the video patterns onscreen. It’s in the vein of Atari Video Music, but with heavily upgraded hardware and software. The VID PIX comes in BOTH a handy Eurorack module and a console version for non Eurorack users.   Incoming audio animates custom graphics in an 8 bit style. Program your own code! For code updates, programming instructions and more, please visit our Github page here.   The post Sound Study VID PIX Module first appeared on Synthrotek ..read more

CLICK HERE TO BUY The MIXIV is a four channel mixer in 4HP.  This is Synthrotek’s first partial SMD kit and it is very fun and easy to build (for SMD).  Channels 1 & 2 can have their own output when cable is patched in to the sub-output jack.  When the sub-output is not patched all channels come out of the main output.  Mix CV or Audio simply and with sider precision! Very skiff friendly at only 26mm deep!Current Draw: +12 – 15mA, -12 – 10mA, +5 – 0 ..read more
