1U Tile Specs



The Spring Reverberation tile allows you to add the unique sound of a real spring reverb into a compact 1U space.  The tile has controls for drive, feedback and mix and has jacks for a mixed output, direct tank and external feedback.

The “DRIVE” control determines how hard the tank is excited by the signal patched to the “IN” jack.  The “FEEDBACK” control provides a normalized internal loop with soft clipping that is active only when nothing is patched into the external feedback jack “EXT FB”.  When a cable is patched into the “EXT FB” jack, the internal feedback is broken and the “FEEDBACK” control becomes a secondary drive into the tank.  The “TANK” output jack provides access to the full wet signal from the tank for processing feedback loops or external mixing.  The “OUTPUT MIX”  sets the wet/dry mix on the “OUT” jack.

The  Spring Reverberation tile is designed to work with tanks with an input impedance of 150 to 200 ohms and output impedance’s of 1500 to 2600 ohms.  Send and return headers are used for connecting to the Accutronics “Blue Reverb” mini reverb tanks (2BF2 & 2BF3).  An adapter cable is available for using the Spring Reverberation tile with tanks using traditional RCA jack inputs.  When experimenting with alternative tanks it is important that only tanks with floating input coils are used (insulted input).  The Amplified Parts webpage has some useful information about reverb tanks here.
