SynQuaNon Demo System Detailed View
Front view:

Back panel view:

There are eight 1/4" TRS jacks on the back, six for balanced line outputs and two for balanced line inputs. These are all connected to the corresponding 1U modules in the top row. The MIDI jacks and USB connector are intended to be used with the Intellijel 1U MIDI module, which is not included in these systems. Finally on the far right there is a connector for the AC adapter and a power switch.
The modules are listed by row below. Highlighted links to ModularGrid pages provide more information on each module, as well as manufacturer's page links where manuals can be found. While these manuals will also be sent with the system in printed form, it is highly recommended to study them in advance.
Top row 1U:
Intellijel Buff Mult 1U Dual 1x4 Buffered Multiple (2x)
SynQuaNon Blank Panel 22HP 1U
Intellijel Digiverb 1U Digital Reverb Effect
Intellijel Audio I/O 1U Dual Balanced Line Audio Input and Balanced Line Audio Output
Intellijel Stereo Line Out 1U Stereo Balanced Line Audio Output (2x)
The Audio I/O and two Stereo Line Out modules are connected to the TRS jacks on the back panel. The three modules perform the necessary conversion between Eurorack (using the 3.5mm jacks on their front panels) and line level signals at the TRS jacks.
Top row 3U:
SynQuaNon 13-Pin Input Breakout Roland/BOSS GK Guitar Interface
Tenderfoot Electronics pinhl 2020 Triple Passive Low Pass Gates (2x)
SynQuaNon Hex Fuzz Amplifier 6-Channel Fuzz and Overdrive Distortion
SynQuaNon Hex Fuzz Output Expander Tone Controls, Wet/Dry Mix, and Level Control for Hex Fuzz
SynQuaNon Hex VCF 6-Channel VCF with Master Controls
SynQuaNon Hex VCA 6-Channel VCA with Master Controls
omsonic UPE (Universal Panning Expander) Stereo Panning and Mixing Utility
Endorphin.es Milky Way 16 Algorithm Stereo FX Processor
The UPE module is very handy for panning the six channels into a stereo output. The Milky Way module has an impressive array of stereo effects, ranging from reverb, echo, modulation, to looping.
Bottom row 3U:
SynQuaNon 19-Pin Input Breakout Cycfi Research 19-Pin Guitar Interface
SynQuaNon Hex VU Meter 6-Channel Programmable VU Meter for Audio Signals
Bubblesound Instruments HEXa(s)r Six Channel AR / ASR Envelope Generator
Bubblesound Instruments HexVCA Six-Channel VCA
SynQuaNon Hex EF-Gate-Trigger Six Channel Envelope Follower with Gate and Trigger Outputs
Instruo DivKid ochd 8-channel Analog LFOs
Bastl Instruments Knit Rider 6-channel Trigger Sequencer
Erica Synths Pico SCALE CV Attenuator, Booster, Inverter and Offset
Synthrotek MST Expressor Dual Foot Controlled Expression Module
The 19-Pin Input Breakout does not have a built-in amplifier; patch the outputs into the amplifier inputs on the 13-Pin Input Breakout and adjust the levels for desired amplification.
The 6-channel triggered sequencer has gate outputs suitable for the LPG and HEXa(s)r modules and can create a wide variety of rhythms or percussive sounds.
The MST Expressor can accommodate two expression pedals and generate either foot-controlled CVs or modulate audio and CV signals.
Wiring Diagram
The Demo Systems are prewired from the factory with typical SynQuaNon Audio and CV Bus connections:

Since the Bus connections significantly reduce patch cable clutter, it is highly recommended to leave them in place. However, they can be modified with SynQuaNon's assistance. Factory connections should be restored before sending the Demo System off to its next destination.
The included case cover protects the modules while allowing patch cables to remain in place.
Other included items:
Binder with paper copies of all module manuals
Dedicated AC adapter for the system. Caution: do not use any other adapter or serious damage to the system will result!
Bag with lots of different length colored patch cables
Pelican case with padded interior for transportation and shipping
