Vermona fourMulator User Manual

fourMulator - Owner's Manual

Introduction

Do you really need four LFO units in single module? Let's "fourMulate" it
like this: You cannot really have enough LFOs, can you? Even a classic
synthesizer easily offers four targets for LFO modulations. To name a
few: vibrato, pulse width, the filter's cutoff frequency and tremolo. In a
modular synthesizer there are even significantly more options. Now add
the options deriving from a combination of multiple LFOs to create inter­action between the units to make these applications more thrilling.

We could have simply named this module Quad-LFO. However, this felt
too boring on the one hand and it wouldn't describe the fourMulator's
full feature-set on the other. Its four sync able, phase-variable and CV­controllable LFOs are able to create trigger-sequences that can be varied
in real time thanks to a comfortable user interface. fourMulator acts as a
modulation- as well as clock-central and is capable of being your new
clock-reference for your modular synthesizer.

Important Safety Information

1. Read these instructions.

2. Keep these instructions. Alway include these instructions when pas­sing the product on to third parties.

7. Do not block any ventilation openings. Install in accordance with
the manufacturer's instructions.

8. Do not install near any heat sources such as radiators, heat regis­ters, stoves, or other apparatus (including amplifiers) that produce
heat.

9. Do not defeat the safety purpose of the polarized or grounding­type plug. A polarized plug has two blades and a third grounding
prong. The wide blade or the third prong are provided for your sa­fety. If the provided plug does not fit into your outlet, consult an
electrician for replacement of the obsolete outlet.

10. Protect the power cord from being walked on or pinched, particu­larly at plugs, convenience receptacles, and the point where they
exit from the apparatus.

11. Only use attachments/accessories specified by the manufacturer.

12. Use only with the cart, stand, tripod, bracket, or table specified by
the manufacturer, or sold with the apparatus. When a cart is used,
use caution when moving the cart/apparatus combination to avoid
injury from tip-over.

13. Unplug this apparatus during lightning storms or when unused for
long periods of time.

14. Refer all servicing to qualified service personnel.Servicing is requi­red when the apparatus has been damaged in any way, such as pow­er supply cord or plug is damaged, liquid has been spilled or ob­jects have fallen into the apparatus, when the apparatus has been
exposed to rain or moisture, does not operate normally, or has been
dropped.

15. To completely disconnect this apparatus from the AC mains,
disconnect the power supply cord plug from the AC receptacle.

16. WARNING: To reduce the risk of fire or electric shock, do not expo­se this apparatus to rain or moisture.

17. Do not expose this equipment to dripping or splashing and ensure
that no objects filled with liquids, such as vases, are placed on the
equipment.

18. The mains plug of the power supply cord shall remain readily ac­cessible.

Installation

• Ensure that the room in which you use this product is wired in accor-

dance with the local electrical code and checked by a qualified inspec­tor.

• Only use this product indoors.

• Do not install the product in hot, humid, or excessively dusty locati-

ons, in direct sunlight or in locations where it is exposed to externally
generated vibrations.

• Do not place burning objects (e.g. candles) on top of or near the pro-

duct.

• If condensation has formed on the product, e.g. because it was moved

from a cold environment to a warm one, allow the product to acclima­tize to room temperature before using it.

• Do not overload wall outlets and extension cables as this may result in

fire and electric shock.

Getting Startet

To ensure top quality, we carefully inspected the module before packag­ing. Nevertheless, the unit could have been damaged during transporta­tion. Therefore, we ask you to take a serious look at the module when
unpacking. Do not hesitate to contact us, should there be anything
unusual with the unit or its packaging.

You should find the following items in the box:

• the fourMulator module

• a system bus connector cable (compatible to Doepfer's A100, TipTop

Audio Zeus and others)

• four rack screws 3x6mm

• four flat washers 3mm

• four patch chords (2x15cm, 2x30cm)

• this manual

Setup

The fourMulator was designed to work in modular synthesizer systems
using the common euro rack format. Its power supply, connectors and
dimensions match the specifications of Doepfer's A100 modular synthe­sizer system and compatible units. To mount the module into your sys­tem's frame, carry out the following steps:

1. Switch off the power-supply. Safety first: Remove the detachable
power cable from your frame – it is possible that you accidentally
touch the internal power transformer.

2. Connect the supplied ribbon-cable to the module's rear. The corre­sponding plug socket is protected against reverse polarity. The rib­bon-cable will only fit in one direction.

3. Connect the ribbon-cable's other side to an empty plug-socket of
your frame's system bus. Make sure the color coded side of the
cable points downwards (-12V)!

ATTENTION Connecting the ribbon-cable with reverse polarity

can lead to damage of your module when powe­ring the system!
