EMG BTS System Instruction Manual

1. Introduction

The EMG BTS System is a specialized tone control module designed exclusively for use with EMG active pickups. This system provides enhanced tonal shaping capabilities for your instrument. It features dedicated controls for bass and treble frequencies, allowing for precise adjustments to your sound.

All controls are center-detented, facilitating quick returns to a neutral tone setting. A dual-dip switch located on the PC board enables four distinct high-end frequency response programs, offering customization to suit various musical preferences and instrument setups.

2. Key Features

• Bass Control: Provides approximately 12dB of cut and boost for bass frequencies.
• Treble Control: Provides approximately 12dB of cut and boost for treble frequencies.
• Center Detent: All tone controls feature a center detent for easy return to a flat response.
• Dual-Dip Switch: Allows for four programmable high-end frequency response settings.
• Compatibility: Designed specifically for EMG active pickups.
• Solderless Connections: Facilitates easier installation (requires compatible EMG pickup connectors).

3. Setup and Installation

Installation of the EMG BTS System requires careful attention to wiring and component placement. This system is designed for use with EMG active pickups and utilizes solderless connections for convenience. Ensure all components are handled with care to prevent damage.

3.1 Component Overview

3.2 Wiring Connections

1. Compatibility Check: Verify that your existing pickups are EMG active pickups. The BTS System is not compatible with passive pickups or other active systems.
2. Power Supply: The system operates on a single 9V battery. Ensure the battery is correctly connected to the power input.
3. Pickup Connections: Connect your EMG active pickups to the designated input terminals on the BTS system. Note that while the system uses solderless connections, specific pickup connectors may need to be acquired separately if not already present on your pickups.
4. Output Jack: Connect the output of the BTS system to your instrument's output jack.
5. Grounding: Ensure all components are properly grounded to minimize noise.

3.3 Dip Switch Configuration

The dual-dip switch on the PC board allows for customization of the high-end frequency response. Experiment with different settings to find the sound that best suits your instrument and playing style. Refer to the diagram below for switch positions and their corresponding frequency responses (Note: Specific frequency details may vary; consult EMG's official documentation for precise values).

• Setting 1: (Example: Both switches OFF) - Standard high-end response.
• Setting 2: (Example: Switch 1 ON, Switch 2 OFF) - Slightly brighter high-end.
• Setting 3: (Example: Switch 1 OFF, Switch 2 ON) - Milder high-end roll-off.
• Setting 4: (Example: Both switches ON) - Enhanced high-end presence.

4. Operation

Once installed, the EMG BTS System provides intuitive control over your instrument's tone. The system typically includes controls for master volume, balance, bass, and treble, depending on your specific configuration.

4.1 Tone Controls

• Bass Control: Rotate the bass knob clockwise to boost bass frequencies, and counter-clockwise to cut them. The center detent represents a neutral (flat) bass response.
• Treble Control: Rotate the treble knob clockwise to boost treble frequencies, and counter-clockwise to cut them. The center detent represents a neutral (flat) treble response.

The 12dB cut and boost range for both bass and treble allows for significant tonal variation. Adjust these controls to achieve your desired sound, from warm and mellow to bright and articulate.

4.2 Master Volume and Balance (if applicable)

If your BTS System configuration includes master volume and balance controls, operate them as follows:

• Master Volume: Adjusts the overall output level of your instrument.
• Balance Control: Blends the output of multiple pickups (e.g., neck and bridge pickups) to achieve a desired mix.

5. Maintenance

The EMG BTS System is designed for durability and requires minimal maintenance. Adhering to these guidelines will help ensure its longevity and optimal performance:

• Battery Replacement: Replace the 9V battery regularly, especially if you notice a decrease in output level or tonal clarity. Active systems are powered by the battery.
• Cleaning: Keep the control knobs and surrounding areas clean. Use a soft, dry cloth to wipe away dust and grime. Avoid using abrasive cleaners or solvents.
• Connections: Periodically check all connections to ensure they are secure. Loose connections can lead to intermittent signal or noise.
• Storage: When not in use for extended periods, consider removing the battery to prevent potential leakage and damage to the circuit.

6. Troubleshooting

If you encounter issues with your EMG BTS System, consult the following troubleshooting tips before seeking professional assistance:

6.1 No Sound or Weak Output

• Check Battery: Ensure the 9V battery is fresh and correctly installed. A dead or weak battery is a common cause of no sound or low output from active systems.
• Verify Connections: Inspect all wiring connections, especially those to the pickups, output jack, and battery. Ensure they are secure and properly seated.
• Output Jack: Confirm the instrument cable is fully inserted into the output jack.

6.2 Excessive Noise or Hum

• Grounding: Ensure all components are properly grounded. Improper grounding can introduce hum.
• Loose Connections: Check for any loose wiring connections within the system.
• External Interference: Test the instrument in different locations to rule out external electrical interference from lighting, power supplies, or other electronic devices.

6.3 Tone Controls Not Functioning

• Wiring: Re-check the wiring for the bass and treble controls. Ensure they are correctly connected to the main circuit board.
• Dip Switch Settings: Verify the dip switch settings. Incorrect settings might lead to unexpected tonal behavior.
