What is the E580?
The Synthesis Technology E580 is a mono-in, mono-out audio digital delay that uses a unique
‘resampling’ algorithm to mimic analog BBD and tape delays. Analog delays have the property
that when the delay time is changed, the pitch of the output changes. The E580 recreates this
effect. There are 3 modes: clean, BBD and Tape. The BBD mode adds a low-pass filter that is
based on delay time as well as noise. The Tape mode adds non-linear distortion (tape
saturation effect) and “wow & flutter” (motor speed variations). The E580 has 2 outputs: a
main Delay and a Tap. The Tap is a percentage (0-100%) of the main Delay. All 4 panel
controls are also under CV (-5V to +5V range).
Connecting to the power supply
The E580 can use either a MOTM 4-pin, MTA-156 style connector (+-15V) or a 16-pin Euro
style (+-12V) connector. See the photos below. The Euro ribbon cable has a red stripe to
indicate -12V. The supplied Euro power cable is keyed so that when inserted in the E580, the
red stripe is ‘down’ (towards the jacks) and by the white lettering on the pc board.
