What is it? The Sound of Shadows (SoS) is a voltage-controlled (VC) digital delay module based around the PT2399 echo IC from Princeton Technology – which was, by the way, originally designed for Karaoke equipment. As with all f(h) products, the SoS was engineered towards maximizing functionality while keeping cost as low as possible.

delay steps through its memory array and thusly the amount of delay. Clockwise rotation increases the rate (which decreases the delay time), counter-clockwise decreases the rate (which increases the delay time). Feedback: Controls how much of the delayed signal is fed back into the delay cell.

disconnect the output of the delay cell from the input of the feedback cell, with the inserted signal now going directly to the feedback gain cell. One use for this is to insert an effect – or even another delay unit (yes, they can be daisy-chained quite effectively) –...
OF HARMONY CANNOT ACCEPT RESPONSIBILITY FOR ANY DAMAGE CAUSED BY USE OF THIS FEATURE. The Chaining Delay Trimmer only affects the chained signal connected to the Delay In pin and has no effect on unchained devices. Power The power connector header is a 2x8/16-pin shrouded box header which accepts the standard Doepfer power cable.
