The module features a large central 'AMOUNT OF SHIFT' knob, 'SQUELCH THRESHOLD', 'SCALE', 'ZERO ADJUST', and 'MIXTURE' knobs, along with 'SIG IN', 'CTRL 1', 'CTRL 2', 'CTRL 3', 'OUT A', 'OUT B', and 'MIX OUT' jacks.

2. Setup

2.1 Unpacking and Inspection

Carefully remove the module from its packaging. Inspect the module for any signs of damage during transit. If any damage is found, contact your dealer immediately.

2.2 Power Requirements

The Behringer 1630 is a Eurorack module and requires a standard Eurorack power supply. Ensure your power supply can provide sufficient current for the module. Refer to your Eurorack case manual for power distribution details.

2.3 Installation

1. Turn off and unplug your Eurorack case before installation.
2. Locate an available 14HP (HP-HSC) space in your Eurorack case.
3. Connect the ribbon cable from your power supply to the module's power header. Ensure the red stripe on the ribbon cable aligns with the -12V pin on both the module and the power bus board. Incorrect connection can damage the module.
4. Mount the module into your Eurorack case using the provided screws. Do not overtighten.
5. Once securely mounted, you can reconnect power to your Eurorack case.

3. Operating Instructions

The 1630 Bode Frequency Shifter is designed to create unique sonic textures by shifting the frequency of an input signal. It can produce metallic, bell-like, or ring-modulator type sounds.

3.1 Controls and Jacks Overview

• AMOUNT OF SHIFT: This large central knob controls the primary frequency shift amount. It features both linear and exponential scales, allowing for precise or dramatic shifts. The range is from -50 to +50 Hz (linear) and 2 Hz to 2 kHz (exponential).
• SQUELCH THRESHOLD: Adjusts the input signal level at which the frequency shifting begins. Useful for noise reduction or creative gating effects. Range from -60 dB to 0 dB.
• SCALE: Controls the overall scaling of the frequency shift. This knob works in conjunction with the AMOUNT OF SHIFT. Range from 0 to 5K.
• ZERO ADJUST: Fine-tunes the zero-point of the frequency shift, ensuring accurate pitch centering when desired.
• MIXTURE: Blends the dry input signal with the wet (frequency-shifted) signal. 'A' represents the shifted signal, 'B' represents the dry signal.
• SIG IN: Audio input jack for the signal to be processed.
• CTRL 1, CTRL 2, CTRL 3: Control Voltage (CV) input jacks for modulating various parameters of the frequency shifter. Refer to advanced patching guides for specific assignments.
• OUT A: Output for the frequency-shifted signal.
• OUT B: Output for the dry (unprocessed) signal.
• MIX OUT: Output for the blended signal, as set by the MIXTURE knob.

3.2 Basic Operation

1. Connect an audio source (e.g., an oscillator, drum machine) to the SIG IN jack.
2. Connect OUT A, OUT B, or MIX OUT to an audio mixer or another module for further processing.
3. Adjust the AMOUNT OF SHIFT knob to hear the frequency shifting effect. Experiment with both the linear and exponential ranges.
4. Use the MIXTURE knob to blend the original signal with the shifted signal.
5. Fine-tune the SQUELCH THRESHOLD to control when the shifting engages based on input level.
6. Utilize the SCALE and ZERO ADJUST knobs for more nuanced control over the shifting characteristics.

4. Maintenance

The Behringer 1630 module is designed for reliable operation with minimal maintenance. Keep the module clean and free from dust. Use a soft, dry cloth for cleaning the front panel. Do not use abrasive cleaners or solvents. Avoid exposing the module to extreme temperatures, humidity, or direct sunlight.

5. Troubleshooting

• No Sound:
  • Ensure the module is correctly powered and the ribbon cable is properly connected (red stripe to -12V).
  • Check all patch cable connections (SIG IN, OUT A/B/MIX OUT).
  • Verify that the input signal is present and at an appropriate level.
  • Adjust the SQUELCH THRESHOLD knob.
  • Check the MIXTURE knob setting.
• Unexpected Sound/Noise:
  • Ensure proper grounding of your Eurorack system.
  • Check for loose connections or damaged patch cables.
  • Adjust the SQUELCH THRESHOLD to filter out low-level noise.
  • Experiment with the ZERO ADJUST knob to eliminate unwanted artifacts.
• Module Not Responding to CV:
  • Verify that the CV source is active and connected to the correct CTRL input.
  • Check the CV signal range and ensure it is compatible with Eurorack standards.
