Behringer SYSTEM 55 Modular Synthesizer User Manual

1. Introduktion

Welcome to the Behringer SYSTEM 55 Modular Synthesizer user manual. This document provides essential information for the proper setup, operation, and maintenance of your new modular synthesizer system. The SYSTEM 55 is a pre-assembled modular synthesizer featuring 38 vintage-sounding modules from the 1970s, designed to offer unparalleled sonic exploration and creative freedom.

Please read this manual thoroughly before operating your SYSTEM 55 to ensure safe and optimal performance.

2. Produktet er slutview

The Behringer SYSTEM 55 is a comprehensive modular synthesis solution, housed in two EURORACK GO cases. It includes a wide array of modules for sound generation, filtering, modulation, and control. Key components include:

• 914 FIXED FILTER BANK: Features 12 active bandpass filters ranging from 125 Hz - 5.6 kHz, plus low-pass and high-pass filters for precise tonal shaping.
• 923 FILTERS: Provides 6 dB low and high pass filters, along with white and pink noise sources for adding texture and percussive elements.
• 904B VOLTAGE CONTROLLED HIGH PASS FILTER & 904A VOLTAGE CONTROLLED LOW PASS FILTER: Essential modules for dynamic frequency manipulation.
• 992 KONTROL VOLTAGES: Allows for CV mixing and switching with an inverting attenuator, crucial for complex modulation routing.
• Multiple Voltage Controlled Oscillators (VCOs), Envelope Generators, and other utility modules.

3. Opsætning

The Behringer SYSTEM 55 comes pre-assembled within its EURORACK GO cases, simplifying initial setup. Follow these steps to get started:

1. Udpakning: Carefully remove the synthesizer from its packaging. Retain all packaging materials for future transport or storage.
2. Placering: Place the SYSTEM 55 on a stable, flat surface. Ensure adequate ventilation around the unit.
3. Strømtilslutning: Connect the provided power adapter to the DC input on the rear of the unit. Plug the adapter into a suitable power outlet. Ensure the power switch is in the OFF position before connecting.
4. Lydudgang: Connect the main audio output(s) of the SYSTEM 55 to your audio interface, mixer, or amplifier using appropriate cables (e.g., 1/4-inch TS cables).
5. MIDI-forbindelse (valgfrit): If using the MIDI-to-CV converter, connect your MIDI controller or computer's MIDI output to the MIDI input on the converter module.
6. Initial Patching: For first use, you may want to create a simple patch (e.g., VCO output to VCF input, VCF output to VCA input, VCA output to main mixer, and an Envelope Generator to VCA CV input) to confirm basic functionality.

4. Operating the SYSTEM 55

Operating the SYSTEM 55 involves understanding the function of each module and how they interact through patching. Modular synthesis is an experimental process, so feel free to explore and deviate from standard practices.

4.1 Basic Signal Flow

A typical basic signal flow in a modular synthesizer involves:

1. oscillation: Voltage Controlled Oscillators (VCOs) generate the raw sound waves (e.g., sine, saw, square).
2. Filtrering: Voltage Controlled Filters (VCFs) shape the timbre of the sound by removing or emphasizing certain frequencies.
3. Ampliifikation: Voltage Kontrolleret Amplifiers (VCAs) control the volume of the sound, often modulated by an Envelope Generator.
4. Modulering: Envelope Generators (EGs) and Low-Frequency Oscillators (LFOs) provide control voltages (CV) to dynamically change parameters of other modules (e.g., VCF cutoff, VCA level).

4.2 Patching

Patching involves connecting modules using patch cables. The SYSTEM 55 uses standard 3.5mm (1/8-inch) patch cables. Always ensure cables are securely connected but do not force them. Experiment with different connections to discover new sounds.

4.3 MIDI-to-CV Conversion

The integrated MIDI-to-CV converter allows you to control the SYSTEM 55 using a MIDI keyboard or sequencer. This module translates MIDI note and control change messages into analog control voltages (CV) and gate signals, which can then be patched to control VCO pitch, VCA gates, and other parameters.

5. Vedligeholdelse

Proper maintenance ensures the longevity and optimal performance of your Behringer SYSTEM 55.

• Rensning: Brug en blød, tør klud til at rengøre enhedens yderside. Ved genstridigt snavs kan du bruge en let tør klud.amp cloth with mild soap can be used, ensuring no liquid enters the modules or connections. Avoid abrasive cleaners.
• Støvbeskyttelse: When not in use, cover the synthesizer to prevent dust accumulation, which can affect module performance and longevity.
• Opbevaring: Opbevar enheden et køligt, tørt sted væk fra direkte sollys, ekstreme temperaturer og høj luftfugtighed.
• Kabelstyring: Keep patch cables organized and avoid excessive bending or tangling to prevent damage.

6. Fejlfinding

If you encounter issues with your SYSTEM 55, refer to the following common troubleshooting steps:

• Ingen lyd:
  • Check all power connections and ensure the unit is powered on.
  • Verify audio output cables are correctly connected to your mixer/interface and that volume levels are up.
  • Review your patch cables. Ensure a complete signal path from sound source (VCO) through VCF and VCA to the main output.
  • Confirm that VCA and VCF modules are receiving appropriate CV/gate signals to open them.
• Modulet svarer ikke:
  • Check if the module is properly seated in its rack.
  • Ensure all patch cables connected to the module are secure.
  • Test the module with a known working patch or by swapping it with another similar module if possible.
• Uønsket støj/brummen:
  • Ensure all power cables are properly grounded.
  • Try connecting the unit to a different power outlet.
  • Tjek for jordsløjfer i din lydopsætning.
