ART SPLITCOMPRO 2-Way Microphone Splitter and Combiner User Manual

1. Introduction

The ART SPLITCOMPRO is a versatile audio device designed to either split a single microphone signal into two distinct outputs or combine two microphone signals into a single output. This unit is engineered for professional audio applications, providing reliable signal routing with minimal distortion and a wide frequency response. It is an essential tool for studio recording, live sound, and monitor applications, offering flexible connectivity for various audio setups.

2.1 Key Features

• Microphone Splitter: Splits one microphone signal into two outputs (one direct, one isolated).
• Microphone Combiner: Combines two microphone signals into one output.
• Phantom Power Handling: Passes phantom power to the main mic input in splitter mode; blocks phantom power from the isolated mic output.
• Ground Lift Switch: Helps eliminate hum and buzz caused by ground loops.
• Phase Invert Switch: Corrects phase issues between signals.
• Low Distortion and Wide Frequency Response: Ensures high-fidelity audio signal integrity.

3. Setup and Connections

Proper connection is crucial for optimal performance. Always ensure all audio equipment is powered off before making connections.

3.1 As a Microphone Splitter

1. Connect your microphone to the MAIN MIC INPUT XLR jack.
2. Connect the MAIN OUTPUT XLR jack to your primary mixer or FOH (Front of House) console. This output is direct-coupled and will pass phantom power from the mixer to your microphone if required.
3. Connect the ISOLATED OUTPUT (SPLITTER) XLR jack to a secondary mixer, such as a monitor mixer or recording device. This output is transformer-isolated, preventing phantom power from reaching the secondary device.
4. Ensure all XLR cables are balanced for best performance.

3.2 As a Microphone Combiner

1. Connect the first microphone to the MAIN MIC INPUT XLR jack.
2. Connect the second microphone to the ISOLATED MIC INPUT (COMBINER) XLR jack.
3. Connect the MAIN OUTPUT XLR jack to your mixer's microphone input. This output will carry the combined signal of both microphones.
4. Note that when used as a combiner, phantom power from the mixer connected to the MAIN OUTPUT will only be supplied to the microphone connected to the MAIN MIC INPUT. The ISOLATED MIC INPUT (COMBINER) does not pass phantom power.

4. Operating Instructions

The ART SPLITCOMPRO features two control switches for signal optimization.

4.1 Ground Lift Switch

• The GROUND LIFT switch disconnects the ground connection between the input and output.
• If you experience hum or buzz in your audio signal, especially when connecting to different pieces of equipment, try toggling this switch.
• Switching to LIFT can often eliminate ground loop noise. If no hum is present, leave it in the GND (grounded) position.

4.2 Phase Invert Switch

• The PHASE INVERT switch reverses the polarity of the audio signal.
• This is useful when combining signals from multiple microphones or when splitting a signal to different destinations where phase cancellation might occur.
• If your audio sounds thin or lacks low-end when combining signals, try toggling this switch to INVERT to see if it improves the sound. Leave it in NORM (normal) if no phase issues are detected.

5. Maintenance

The ART SPLITCOMPRO is designed for durability and requires minimal maintenance.

• Keep the unit clean by wiping it with a soft, dry cloth. Avoid using liquid cleaners or solvents.
• Protect the unit from excessive moisture, extreme temperatures, and direct sunlight.
• Ensure all cable connections are secure and free from damage.

6. Troubleshooting

If you encounter issues with your ART SPLITCOMPRO, refer to the following common solutions:

• No Audio Output:
  • Verify all XLR cables are securely connected to the correct inputs and outputs.
  • Ensure the microphone is functioning correctly and receiving phantom power if it's a condenser microphone (only via MAIN MIC INPUT).
  • Check the input and output levels on your connected mixers/devices.
• Hum or Buzz in Audio:
  • Toggle the GROUND LIFT switch to the LIFT position. This often resolves ground loop issues.
  • Ensure all equipment is properly grounded.
• Thin Sound or Phase Issues:
  • If combining signals or experiencing unusual sound quality, toggle the PHASE INVERT switch to the INVERT position.
  • This can correct phase cancellation that might occur when multiple microphones are used or when signals are split to different paths.
