BEHRINGER CT200 Microprocessor-Controlled Cable Tester User Manual

Introduction

The BEHRINGER CT200 is a microprocessor-controlled cable tester designed for comprehensive analysis of various cable types. It features three primary modes: cable test, installed cable test, and test tone mode. This versatile device accepts all standard connectors including XLR, Speakon, TRS (1/4", 1/8"), RCA, RJ45, MIDI, and USB. It provides super-easy operation with an intuitive LED display, offering continuity checks, intermittent contact detection, phantom-power checks, and ground-shield checks. This manual will guide you through the setup, operation, maintenance, and troubleshooting of your CT200 to ensure optimal performance.

Setup

1. Battery Installation: The CT200 requires two AA batteries for operation. Locate the battery compartment on the underside of the device. Unscrew the cover, insert the batteries according to the polarity markings, and replace the cover, ensuring the screw is securely fastened.
2. Power On: Locate the power switch on the device. Slide it to the "ON" position. The LED display should illuminate, indicating the device is ready for use.
3. Mode Selection: The CT200 offers different testing modes. Select the appropriate mode (Cable Tester, Test Tone, or Phantom) using the MODE switch based on your testing requirements.

Operating Instructions

The CT200 provides intuitive testing for a wide range of cables. Follow these steps for effective cable analysis:

1. Cable Test Mode

• Set the MODE switch to "CABLE TESTER".
• Connect one end of the cable to an "INPUT" port and the other end to an "OUTPUT" port.
• The LED display will show the continuity of each pin. A lit LED indicates a good connection.
• The device checks for crossed wires, shorted connections, open circuits, and intermittent contacts.
• For cables with multiple pins (e.g., XLR), the display will show the connection status for each pin (Pin 1, Pin 2, Pin 3, Tip, Ring, Sleeve).
• If an issue is detected, the corresponding "CROSSED", "SHORTED", "OPEN", or "INTERMITTENT" LED will illuminate.

2. Test Tone Mode

• Set the MODE switch to "TEST TONE/PHANTOM".
• Select the desired tone level using the "TONE LEVEL" switch (+4 dBu, -10 dBV, or -50 dBV/MIC).
• Connect the cable to the appropriate output port (e.g., XLR OUT, 1/4" OUT).
• The CT200 will generate a test tone, which can be used to trace signals through a sound system or confirm signal flow.

3. Phantom Power and Ground-Shield Check

• In "TEST TONE/PHANTOM" mode, the device can also check for phantom power presence and ground-shield integrity.
• Connect an XLR cable to the XLR input. The "PHANTOM" LED will light up if phantom power is detected.
• The "GND/SHIELD PASS" LED indicates proper grounding.

4. Supported Connectors

The CT200 supports a wide array of connectors, making it an indispensable tool for audio professionals and enthusiasts:

• XLR (3-pin)
• Speakon (4-pin)
• TRS (1/4" and 1/8")
• RCA
• RJ45 (Ethernet)
• MIDI (5-pin DIN)
• USB (Type A and B)

Maintenance

• Cleaning: Use a soft, dry cloth to clean the exterior of the CT200. Avoid using abrasive cleaners or solvents, as they may damage the finish or internal components.
• Battery Replacement: Replace batteries when the display dims or the device behaves erratically. Always use fresh AA batteries.
• Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures.
• Connector Care: Keep all input and output connectors free from dust and debris to ensure reliable connections and accurate readings.

Troubleshooting

• No Power:
  • Check if batteries are correctly installed and have sufficient charge.
  • Ensure the power switch is in the "ON" position.
• Inaccurate Readings:
  • Ensure cables are fully inserted into the correct input/output ports.
  • Clean connectors if they appear dirty or corroded.
  • Test with a known good cable to verify the tester's functionality.
• Intermittent Connection Indication:
  • If the "INTERMITTENT" LED lights up, gently flex the cable near the connectors while testing. This can help pinpoint loose or faulty internal connections.
  • This feature is particularly useful for diagnosing issues that are not constant breaks but occur under movement or stress.
• Phantom Power Not Detected:
  • Ensure the connected device is supplying phantom power.
  • Verify the XLR cable is functioning correctly with another test.
