What is the E340?

The Synthesis Technology E340 is a dual-output VCO that contains 8 VCOs. These VCOs can
be detuned by a control voltage (SPREAD) and then FM'd by varying amounts of bandpass-
filtered white noise (CHAOS sets the depth of FM and CHAOS BW sets the 'speed' of the
modulation). The effect achieved can range from the 'Super Saw' sound of the '80s to a
swarm of bees.
Since the E340 does not have built-in CV attenuators, you normally first attenuate a CV
before plugging it into the E340. If you want to use a full-scale, -5V to +5V signal, the panel
knob must be set straight up ('12:00 position') or the internal voltage clamps will limit the
swing. Remember, any applied CV to a jack is added to the position on the panel knob for
that function. Overdriving a CV input may cause pitch changes.

Connecting to the power supply

The E340 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 E340,
the red stripe is 'down' (towards the jacks) and by the white lettering on the pc board.

Summary of Contents for Synthesis Technology E340

  • Page 1 Since the E340 does not have built-in CV attenuators, you normally first attenuate a CV before plugging it into the E340. If you want to use a full-scale, -5V to +5V signal, the panel knob must be set straight up (’12:00 position’) or the internal voltage clamps will limit the swing.
  • Page 2 9 – FM CV input. Modulates the VCO fundamental pitch. 10 – SYNC input. A positive voltage exceeding +0.25V will place the E340 VCOs into ‘hard sync (both outputs reset to -5V). The SYNC effect can sound rather interesting at higher SPREAD settings.
