Synergy D1
"Hardware for a New Era"
3 analog saturation circuits, digital delay and modulation.
Hardware product.
Full DAW control and automation and easy preset management with presets stored on the computer drive or in the HW unit.
Requires API500 system lunchbox.
Takes up two positions in the API500 rack, processes signal from inputs to outputs of both positions.
Connects to a Mac or PC via micro USB connector, the cable is included.
Stereo or mono input and stereo output.


There is no mystery in the standard delay. But D1 is a fine combination of effects offering something what is hard to describe but it is a pleasure to hear it.

Powerful DSP delivering phaser, chorus and flanger modulations
3 selectable pure analog saturation circuits
Has its own vibe like no other delay
Plug-in control and parameter automation
Top quality analog components and AD/DA converters
Designed, built and produced in the EU

Loaded with experience

The Synergy R1 quality is based on the experience of the whole Audified team. It is a culmination of everything we have discovered in 20 years of work in the audio industry. Read more about the background of the Synergy D1 value

We have created precise models of vintage devices which include control plug-ins and other solutions for the famous companies in the audio industry. We produce hardware with extreme demands for reliability, which are installed in countless studios in widespread locations. Our team participates in research and teaches audio engineering at a technical university. All this experience is reflected in the Synergy D1. We continue in our development and we are constantly planning improvements, but there’s no need to spend money on a new unit: The complete firmware including control, indication and reverb algorithms can by updated from the Synergy D1 control application.

Elegant extension
of your API500 collection

Synergy D1 is a module for API 500 series lunchboxes. There is no compromise in the Synergy design although it takes only a small portion of the valuable space in your studio. Read more about Synergy R1 design

You will be surprised by the front panel and its ease of use. The display offers both analog and digital indication of parameter values which are clearly visible even if your rack is located further away in your set up. There is no need to browse through countless parameter pages, all parameter value indicators are visible simultaneously. The brightness of the display is adjustable, either manually or automatically. You can also turn it off if you prefer. The weakest aspect of all hardware devices are the moving components. But Synergy D1 uses extremely durable ALPS encoders with deep bearing.

Modulation & Delay

The Delay and LFO Modulation section of the D1 is digital. It contains premium quality 24 bit A/D and D/A converters, 32 bit floating point DSP and true bypass function. The DSP offers 3 modulation algorithms.


The analog section contains three switchable premium saturation circuits with Germanium diodes, J-FET transistors and with discrete Op-Amp in the standard socket. You can control the analog gain and the wet/dry ratio from the device or from a connected computer. You can therefore use the D1 unit as a 100% analog saturator or a 100% digital reverb processor, if you wish (and everything else between those 2 worlds).

Ordinary hardware

Modern producers tend to turn their backs to audio hardware effects. Recalling sessions is time consuming so they rather decide to sacrifice their CPU power to plug-ins.

Audified Hardware

But Synergy is different. The USB connection lets you control the device from your DAW, automate it and store its settings within the session. No more papers. No more turning knobs.

Full SW control

Control every single function of the device using software plug-ins or a standalone application. Adjust the automated parameters and they will be recorded in your DAW. It works even independently for multiple tracks, as one Synergy D1 works with many control plug-in instances. Read more about the software control

The sound


The story about Synergy design

The reason to build our own device is simple: The software models of the vintage devices are very popular, but they utilize the wisdom of engineers of the previous era. We decided to make our own remarkable addition, creating a device for the next era, a device which will be so original that some next generation company will be interested to create a software model after thirty or more years :-)

We started building the analog saturation circuits as a standalone device, equipped with many potentiometers and switches. We have spent a significant time with our cooperatintg artists and engineers searching for values of these parameters to have the best possible sound color.

The digital part has a different story. We believe, the soul is in the algorithms. The quality of the hardware platform in Synergy was proven. It was able to run a quite comples automatic mixer with more than 1200 audio parameters. The board is so universal that it could run many kinds of digital processing, offering a bright future for improvements and more types of similar devices. Putting the digital and the analog parts together was a technical step, but we were surprised that we got much better sounds than we expected when we had both the parts separated.
