Introduction
Congratulations on your purchase of the DELTA CEP A Synthesizer. Whether you use it in
its basic configuration in a modular system or as an expressive solo, bass or sequencer
synthesizer - we hope you enjoy the instrument.
1.1
DELTA CEP A - a semimodular, paraphonic Synthesizer
You probably know what these two adjectives mean. For many of you, they may have even
been the reason to include the DELTA CEP A in your setup. The following paragraphs are
for those who bought the DELTA CEP A because of the sound, without worrying about the
meaning of these two features.
Semimodular?
A modular synthesizer is an electronic sound and noise box made up of individual modules
for sound research, which have no pre-wiring apart from their common power supply.
Sound and noise generating modules, such as oscillators or noise sources can be freely
connected to sound modifying modules such as filters. A third category of modules - the
modulators - such as low-frequency oscillators (LFOs) and envelopes, provide automated
control of sound parameters. For beginners, so much freedom can quickly become
confusing. That’s why semimodular systems such as the DELTA CEP A have pre-wiring,
which greatly simplifies entry into the world of modular systems and, ultimately, electronic
sound generation. Once you gain experience with the pre-wired system, you can break or
add connections to enjoy all the freedom of a modular system.
Paraphonic?
Paraphonic synthesizers can be played polyphonically, because their oscillators allow for
independent pitching according to chords. Although all of its oscillators share the same
filter, VCA, and envelopes, polyphonic oscillator control allows for multiple voices to be
played simultaneously, which is ideal for pad sounds. The DELTA CEP A sounds particularly
good in paraphonic mode, because it consists of two oscillators per voice, which provide a
nice beating effect when two oscillators are detuned against each other.

Installation and first use
Before we go into the detailed description of the DELTA CEP A features, we first need to
install the unit into a Eurorack cabinet. DELTA CEP A Desktop customers can of course skip
this chapter. Before you start to install the module, you should disconnect the mains plug of
the Eurorack cabinet.
Next, calculate the power requirements of the installed modules in the cabinet plus the new
DELTA CEP A synthesizer (12V 140mA, -12V 80mA). To calculate the current consumption,
add the current values of all installed modules. The overall power consumption should be
below the cabinets maximum current for both voltages +12V and - 12V. In the following
example table you see a typical calculation:
