Safety Instructions

I. Never use the instrument in a humid or wet environment, nor near flammable goods. The instrument must never be operated outdoors but solely in dry rooms.
II. No liquids or conducting substances must get into the instrument. Should this be the case, the instrument is to be disconnected from mains power immediately and examined, cleaned and possibly repaired by a qualified technician.
III. Never expose the instrument to temperatures above +50°C or below -10°C. Before operation, the instrument should have a temperature of at least 10°C. Do not expose the instrument to direct sunlight. Do not install the instrument near heat sources like heaters, open fire places, central heating etc. Keep the top of the instrument clear in order to allow proper ventilation, otherwise the instrument could eventually overheat.
IV. Never place heavy objects on the instrument.
V. Transport the instrument carefully, never let it drop or fall over. Make sure that during transport and in use the instrument is supported properly and cannot drop, slip or fall over because people might get injured.
VI. The instrument may only be used for the purpose described in this operating manual. Due to safety reasons, the instrument must never be used for other purposes.

Installation

Before you start

Morphor modules are designed to be used with an Eurorack-compatible case and power supply. We recommend you to use a case with an adequate high-quality power supply. Before installing the module in your case, you must ensure your power supply has a free Eurorack standard PSU connector (2x8 pin header connector) and sufficient available capacity to power the module:

1. Make a separate sum of the +12 V, -12 V and +5 V maximum current draws respectively for all your modules, including the new one. The maximum current draw is specified in the manufacturer's technical specifications for each module. You can use a tool like ModularGrid to help you calculate the total values for your case.
2. Compare each of these sums to the specifications of your case's power supply.
3. Proceed only with the installation if none of the total values exceeds the power supply's specifications. Otherwise you must remove some modules to free up some capacity or upgrade your power supply to allow more capacity in your case. If you do not adequately power your modules, it may result in damage to your modules or power supply. If you are unsure, please contact us before proceeding.
4. Make sure your case has enough free space (HP) to fit the new module. To prevent screws or other debris from falling into the case and shorting any electrical contacts, do not leave gaps between adjacent modules, and cover all unused areas with blank panels. Similarly, do not use open frames or any other enclosure that exposes the backside of any module or the power distribution board.

Installing your module

Always turn off the power to the case and disconnect the power cable when installing or removing a module from your case to avoid injury or equipment damage.

The Morphor Dual VCA uses the -12 V and the +12 V rail of the power supply (using a standard Eurorack 2x8 pin connector). The red stripe of the included ribbon cable (-12 V side) must be oriented on the same side as the "RED -12 V" marking on the module and on your Eurorack power distribution board.

The module draws a maximum current of 35 mA from the +12 V rail and maximum 30 mA from the -12 V rail.

Introduction

The Morphor Dual VCA is a compact and complete dual DC-coupled VCA module. This module will definitely come in handy as a general purpose VCA without taking up too much space.

The two separate VCA sections each feature extensive gain control (main knob + attenuated CV jack), an indicator LED and a switch to select Linear or Exponential control. This way, the module can be used both for audio and CV processing. Without a cable plugged in, the first output gets normalised to the second, resulting in a 2-channel mixer output.

Happy morphing!

Controls & Connections

INPUT [1]

Insert your audio signal in this protected input.

GAIN[2]

Set the gain of each VCA section with these controls. When fully opened, the VCA will have a gain of 1. When fully closed, the signal gets attenuated by up to 120dB.

GAIN CV [3]

Add extra VCA Gain modulation with this bipolar CV input jack. A CV attenuation knob is provided as well.

LIN/EXP CONTROL SWITCH [4]

Each VCA can be used with Linear or Exponentialcontrol. This way, the module can be used for both audio and CV processing. Just flip the switch depending on your needs.

OUTPUT [5]

Your attenuated analogue audio output. Without acable plugged in, the first output gets normalized to the second, resulting in a 2-channel mixer output.

Support

To provide the best possible performance with the highest quality and reliability for music professionals, all Morphor's products are designed, manufactured and tested in-house with the highest possible standards. In case your module is not functioning as it should, make sure to check your Eurorack power supply and all connections first.

If the problem persists, contact your dealer or send an email to [e-mail]. Please mention your serial number, which can be found on the module's rear side.
