Overview
The Hex Fuzz Output Expander module is an important add-on for the Hex Fuzz
Amplifier, creating a large variety of tones with complete control over the mix of
sounds for each of the individual channels."
The module features passive tone control circuitry that consists of low-pass and high-
pass filters with cross-fade control, much like the classic fuzz pedals. The Tone
controls determine the relative amounts of each filter type. On the rear of the module
one can select two different values for each resistor and capacitor in the each of the
two filter types, resulting in 16 different possible response curves for each channel."
The tone circuit outputs are fed into an active buffer with variable gain of 0.1x - 2x via
the channel Volume controls."
The six EQ’d and volume-adjusted fuzz signals are cross-faded with the
corresponding clean guitar inputs (obtained from the Hex Fuzz Amplifier Input Thru
connector) for the desired wet/dry balance."
Ideal for guitar or bass single-string processing."
Made in the USA."

Connections to Hex Fuzz Amplifier
Use two 6-inch (or 12-inch if the modules are not located next to each other) SynQuaNon
Audio Bus cables to connect the Hex Fuzz Output Expander to the Hex Fuzz Amplifier (or
any other SynQuaNon hexaphonic audio effects module) and a third SynQuaNon Audio Bus
cable to connect the Expander output to the input of the next SynQuaNon module in the
signal chain or to the Hex I/O module for patch cable connections to non-SynQuaNon
modules."
1. Connect the FUZZ IN on the Expander to the OUTPUT from the Hex Fuzz (or other
effects output)"
2. Connect the DRY IN on the Expander to the THRU connector on the Hex Fuzz (or other
audio signal you would like to blend with the processed signal)"
3. Finally, connect OUT on the Expander to the next module in the signal chain

Making filter adjustments: "
The upper dip switch is for channels 1 (switches 1-4) and 2 (switches 5-8), the center dip
switch is for channels 3 and 4, while the lower dip switch is for channels 5 and 6. Experiment
with different settings for each or for all channels by rotating the corresponding Tone control
between minimum and maximum and selecting combinations that create the desired tone."

Support
In case of difficulty:"
1. Make sure power is available to the Eurorack and that it is turned ON."
2. Check the rear module power connection (turn OFF Eurorack power first)"
3. Check patch cables for continuity or shorts."
4. Check level settings on front panel. Check gain select header on rear of
module for proper gain range selection (turn OFF Eurorack power first)."
